DEER-TOLERANT ORNAMENTAL PLANTS Jeff Jackson, Professor of Wildlife Management and Retired Gary L. Wade, Extension Horticulturist Reprint from The South Carolina Nurseryman, September/October 2008

As shadows lengthen in the late afternoon, deer leave the shelter of the woods in search of food. They inspect your trees, shrubs and flowers as if they were a buffet table. Nibbling pansies for an appetizer, they progress to azaleas for the main entree. Then it's on to the daylilies for dessert. All across America, this scene is repeated in countless locations where native areas are being replaced by managed grounds. Nuisance deer are difficult to control in residential communities. There are a number of commercially available repellents on the market, but they tend to wash off with rain and must be reapplied frequently to be effective. Unreliable results have also been obtained from other so-called "home remedy" repellents such as soap, human hair and animal dung. Shooting is often prohibited, and many citizens are opposed to this method of control. Fencing whole communities or individual properties is often not practical. Planting ornamental plants that deer do not like to eat is a solution to deer browsing. Please remember, though, that very few plants are totally deer-resistant. When deer populations are high and

food becomes scarce, deer are more likely to feed on ornamental plants. Deer prefer tender new foliage on newly-planted ornamentals and those fertilized to produce lush new growth. During dry weather, deer are attracted to irrigated plants. Buck deer may also cause considerable damage to young trees by rubbing them with their antlers. Repellents will not stop antler rubbing. The following list may be helpful when selecting ornamental plants for your landscape. If your favorite plant is not on the list, information is lacking on its level of deer resistance.

MOST TROUBLESOME WINTER WEEDS Winter weeds are prevalent in nursery crops and flowerbeds Fall and winter are my favorite times of the year. After battling the heat all summer and fighting weeds like torpedograss and bushkiller, winter weeds are a welcomed non-challenger. Cool season weeds are flourishing and it’s time to turn our attention to several unwanted plants that you might see in the nursery and flower bed this winter. Bittercress (Cardamine hirsuta) - Bittercress, members of the Brassicaceae (mustard) family, are considered to be one of the most troublesome weeds in container nursery production in Louisiana. In the wild, bittercress behaves as winter annual but germinates year round in optimal growing conditions found at nurseries. Conditions are perfect this time of the year for bittercress. Populations reach their peak from October to February.

ceae (woodsorrel) family, are perennial weeds that produce numerous creeping above and below ground stems and deep taproots that make hand removal difficult. Woodsorrel has three heart shaped leaf components that vary in color from dark green to reddish purple. Creeping woodsorrel (Oxalis corniculata) has a prostrate growth habit and produces numerous above ground stems, whereas, yellow woodsorrel (Oxalis stricta) grows more upright and produces below ground stems. Both species produce thousands of seed and have a very effective method of seed dispersal. At maturity “okra” shaped seedpods burst open and expel seed 10 to 12 feet in all directions.

The plant can produce as many as 5,000 seed and has an effective method of dispersal that forcefully expels mature seeds two to three feet. Seed are extremely viable and can germinate immediately when growing conditions are favorable. Bittercress matures very quickly and is capable of producing seed 4 weeks after germination.

Heavy seed production is just one reason that makes woodsorrel difficult to manage. The good news is that there are several preemergence options for this particular weed. However, many growers often think their preemergence herbicides failed. The problem could be that the existing plants were allowed to produce stolons and rhizomes before they were hand removed. Once woodsorrel is established, hand pulling often fails to completely remove

Drought Tolerant Plants: Part III Yucca Highlight I am growing 19 species of yuccas and all of them are cold tolerant and drought tolerant here in Mansfield, LA – at least I’ve seen no damage on any of them with temperatures down to as low as 15 degrees F. But one has exceptional beauty. Yucca gloriosa var. recurvifolia ‘Hinvargus Margaritaville’ or simply Margaritaville is a patented plant and introduced around 2001. I acquired mine from Hines Nursery in 2006 and today it stands about 3 ½ feet tall and spreads to about the same. The foliage is gorgeous in that it has green margins followed by a yellow stripe on either side and the middle is light yellowish green to chartreuse. Margaritaville grows to between 4 to 6 feet tall and the flowers form in the center on about a 4 foot spike and are white. The foliage is sharp pointed and leathery in texture. Grow it in full to partial shade and enjoy it as a mass planting or as a specimen plant but give it excellent drainage. Article and image submitted by Severn C. Doughty, Sr.

NEWS, VIEWS & THANK YOU’S August 18, 2011 Dear Mr. Doughty, On behalf of the LSU AgCenter and Burden Horticulture Society (BHS), I want to thank you and the Louisiana Nursery and Landscape Association for helping sponsor “An Evening of Wine and Roses”. Through your generous $250.00 sponsorship, you are contributing greatly to the success of one event and helping BHS raise awareness of beautiful Burden Center. Thank you for helping us preserve and enhance this magnificent green space that makes our community such a nice place to live and work. With appreciation, Gigi Gaithier

October 27,2011 Dear Members of LNLA, On behalf of the Louisiana Nursery Landscape Foundation for Scholarship and Research (LNLFSR), I would like to thank you so much for your most generous, non-specific contribution of $5,000.00 on June 16, 2011 to the Foundation. General, non-specific contributions, will be used to help fund scholarships to Louisiana college students, enrolled in horticulture or closely related fields, provide grants to individuals and research organizations and/or to support institutions providing education in horticulture through financial assistance for research, education and information expenses. LNLFSR is a 501(c)3 nonprofit organization. Your contribution of $5,000.00 is tax-deductible to the extent allowed by law. No other goods or services were provided in exchange for your generous donation. Sincerely, Severn Doughty, Sr., Ph.D.

A Word from our President It’s hard to believe that the holidays are already upon us. The weather has been unseasonably warm and dry and still feels like summer at times. The good news is that spring is getting closer and closer and we certainly have that to look forward too. Since the last newsletter, we have held a membership drive in New Orleans at Perino’s Garden Center. It was held with the help of Lisa Loup and the New Orleans Horticulture Society and a special thank you to Buddy and Peter Perino for hosting the meeting. We had a nice dinner and then had a special presentation by Buddy Lee with Encore and Southern Living plant collections. There were approximately 30 people in attendance and we will see how many new members we pick up. This is something that we need to continue to do as an association. Get out and tell non-members all that the association does for us and our industry. It takes spreading the word and showing the confidence in the association to keep it as strong as it is today. There are many associations that are not as strong as us, but now that we are, we have to keep growing and pushing to be better and stronger. We also recently held an LNLA and a Louisiana Nursery Landscape Foundation for Scholarship and Research (LNLFSR) board meetings at the Hammond Research Station. When the meetings were concluded, Commissioner Mike Strain joined us to walk the grounds of the station. I want to personally thank the Commissioner for his time and let him know how much we appreciate him. During his visit, LNLFSR made a $10,000 contribution handed to Dr. Allen Owings for research and education development there at the station. Finally, please be sure and mark your calendars for the upcoming Gulf States Horticultural Expo in Mobile, AL. The dates are Thursday and Friday, January 19 and 20, 2012. Our annual meeting will be held on Thursday morning at 7:00 A.M., January 19th in the Convention Center. I look forward to seeing you there.

Sincerely, November 16, 2011 Severn and LNLA Board, Thanks for the prayers, concerns, etc., at my mom’s recent passing. I appreciate the contribution to the Forest Hill Baptist Church in my mom’s name as well. Allen Owings

NOTES FROM THE SECRETARY Hello to all my good Friends,

This has been a very busy fall for me and it’s almost been nonstop. It began with my attendance at the Northwest Louisiana Nursery and Landscape Association meeting, held on September 1st, at Keeling Company in Shreveport. The following week I left for the Louisiana Irrigation Association (LIA) 2-day Basic Landscape Irrigation Contractors Training; 27 people preregistered for the event. The class is designed to help attendees learn about the basics of irrigation and potentially pass the exam; although the class doesn’t teach specifically to the exam questions. Interestingly enough, each time we offer the class, we consistently have a 75% pass rate for individuals taking the exam for the first time. I then traveled to Folsom, LA for the SELNA Trade Show, held at Magnolia Park, on September 9th. There was a great turnout. An estimated 175 people were in attendance and 75 of them represented the green industry; being either landscape architects, horticulturists, retail nursery or wholesale nursery personnel. Educational classes were held throughout the day in conjunction with the trade show. I really enjoyed seeing so many of my good nursery friends; some of which I don’t see very often. Dan Gill and I had a block buster Certified Nursery & Landscape Professional Review and Exam on September 22-23, held at the Ira Nelson Horticulture Center in Lafayette. Thirty-seven people registered for the class, 33 took the exam and 19 passed all 5 sections of the exam. Dan taught the lecture portion and I toured the students around the facility and reviewed the plants they might see on the plant identification portion of the exam. On October 4th, I attended the LIA board meeting at Ralph & Kacoo’s Restaurant in Baton Rouge. The next day, I returned to the restaurant to attend the LIA Annual Meeting and Recertification training. The following week, on October 12th, I attended the LNLA board meeting at the Hammond Research Station. Later that afternoon, both LNLA and the Hammond Research Station hosted a tour of the Hammond Research Station trial gardens and a dinner for special guests: LDAF Commissioner Mike Strain and LDAF staff, Craig Roussel and Ansel Rankins. I have to say that Mike Strain is a true friend of the nursery industry and to Louisiana agriculture as a whole.

On Friday, October 14th, I was honored to be asked by Louisiana Southern Garden Symposium committee to conduct a workshop with my dear friend Walter Imahara at Imahara’s Botanical Garden, in St. Francisville. The program was entitled “Inspiration for Creating Your Own Botanical Garden”. About 75 people attended the two workshops. As they toured the gardens, participants learned how to create landscape views, planting techniques for azaleas, trees, palms, cycads and agaves. Participants also learned how to prune topiary shrubs, crape myrtles and trees.

The Louisiana Nursery & Landscape Foundation for Scholarship and Research Update “The Louisiana Nursery Landscape Foundation for Scholarship and Research’s (LNLFSR) Gala II was a huge success. The Gala was held on June 16, 2011 at Rip Van Winkle Gardens, Jefferson Island, LA owned by Mike Richard of Live Oak Gardens. Mike waved the rental fee and the bar and bartender fees to allow the Foundation to receive more revenue - Thank you, Mike, for this most generous gift! Around 75 people attended; special guests included Dr. Neil Odenwald, who gave us a very inspirational message as to the value of the Foundation; and Commissioner of Agriculture, Dr. Mike Strain who provided us with the key note address. Profit earned was $32,069.92, which was considerably more than we earned at Gala I which amounted to $24,239.44. We had live and silent auctions; which earned $2005.00 and $6,842.00, respectively. Everyone who attended thoroughly enjoyed the evening. A special ‘THANK YOU’ is extended to everyone who attended and provided such overwhelming donations and income. Thank you, Fred Hoogland and Allen Owings, for your most generous contribution of $5,000.000 each. Fred’s donation was non-specific and Allen’s was specifically for scholarships. At the October 12, 2011 Foundation Board Meeting, the Board approved a new named scholarship, ‘The Foret, Meadows and Owings Scholarship Award’ from seed money donated by Dr. Allen Owings and honoring the previous LAN/LNLA Executive Secretaries. Interestingly enough, I received a call from the Minnesota Nursery and Landscape Association asking us how we were so successful in raising that amount of money in one evening. Bob Finch, Executive Director of MNLA, and his staff are state-of-the-art in nursery association management, so I was quite honored for them to contact me. Most recently on October 12, 2011, LNLFSR President, Pete Newton, presented Dr. Allen Owings with a check for $10,000.00 at the Foundation’s board meeting. An evening supper was attended by Agriculture Commissioner, Dr. Mike Strain, after a tour of the Hammond Research Station to see the results of research being conducted there. The Foundation will sponsor a Gala annually. You can provide a sponsorship in any one of the following categories: Gold/Event Sponsor at the $5,000.00 level or Silver at the $2,500.00 level or Bronze at the $1,000.00 level. You can sponsor a table at the Gala for $700.00 (Continued on page 19)

The IA Welcomes WaterSense’s Move to Remove 40 Percent Turf Restriction From New Home Labeling Program FALLS CHURCH, VA. (Oct. 25, 2011) – The Irrigation Association applauds the recent announcement of the WaterSense program’s intent to remove the 40 percent turfgrass restriction from the single-family new home specification. WaterSense’s announcement culminates three years of the Irrigation Association’s efforts to remove this option from the new homes specification. Released in December 2009, the final specification of the WaterSense single-family new home labeling program that enabled a new home to qualify for a WaterSense label contained two options for landscape design: 1) adhere to a water budget tool, or 2) restrict the use of turfgrass to 40 percent of the landscapable area. With the recent announcement by WaterSense, the only requirement for builders wishing to be eligible for this labeling would be to adhere to the water budget tool. “This announcement by WaterSense is a huge win for the irrigation industry,” said IA’s Federal Affairs Director John Farner. “IA’s volunteers, staff and green industry partners should celebrate this move.” The WaterSense notification of intent identifies the process for stakeholder input regarding the decision to remove the turfgrass restriction, along with several other changes to the single-family new home specification, including the requirement to use labeled weather -based irrigation controllers. “We look forward to WaterSense implementing these recommendations within the revised new home specification,” continued Farner. “With these recommendations, the Irrigation Association looks to be a strong partner in supporting and promoting WaterSense labeled products, irrigation professionals and programs.” To view the official WaterSense notification of intent, please visit For more information about IA's position on WaterSense labeling, please contact IA Federal Affairs Director John Farner at Editorial Contact: Erin Fisher, Communications Manager, (E), (P) 703.536.7080.

New Orleans CZO The City Planning Commission and citizens of New Orleans have been busy at work shaping a new city following the destruction of Hurricane Katrina. Out of this turmoil has emerged a great vision of the future that involves creating a sustainable city. A city built around sustainable ideas, rules and methods, and more importantly, one of the most innovative landscape codes in the country. The first item of this vision was the GreeNOLA Plan, created soon after the hurricane, that sets forth a strategy for a sustainable future. Following this, the city, working with planning consultant, Goody Clancy from Boston, and several other technical consultants, spent well over a year working with citizens to prepare a new Master Plan referred to as the Plan for the 21st Century, New Orleans 2030. According to this plan, the vision includes building a ‘green city’ exhibiting environmental innovation, energy efficiency, green building regulations and urban agriculture. The master plan of course addresses a new land use plan, parks, open space and a complete overhaul of the city Zoning Ordinance known as the CZO. It is this last step that interests members of the green industry the most.

CZO The Comprehensive Zoning Ordinance will be used to build the new city of the future. Public hearings are now being held to replace the very outdated ordinance that has been in use in the city and parish for many decades.

The CZO will devise new standards based upon sustainable practices for land use, building disposition, lot size, setbacks and building standards for even paving, storm water management and landscaping. Known as Article 23 of the CZO, this draft landscape code addresses landscape, stormwater management & screening. The draft ordinance shows promise of being one of the most interesting in the country. Primarily since it’s driving objective is landscape sustainability.

Article 23 In many ways this is a good landscape code for a large redeveloping city. New Orleans is the last large city in the country to write a landscape code. Both the public and the building industry will accept this code as a reasonable method to ensure that the special character of New Orleans is maintained and will benefit both tourists and citizens while protecting property values. The basic design elements to be addressed in the landscape code include “landscape yards, parking lot landscaping, buffer yards, screening, parkway trees, tree preservation, irrigation, stormwater management and plant material standards.” But what is not addressed are parking lot detentions and drive thru service lanes. Landscape plans must be drawn, reviewed and permits issued. But one thing that should be added to the code is a way to measure sustainable results of landscape design. The way to do this is to require that the landscape plan be designed to achieve a minimum One Star Rating based upon the LEED-SITESTM Sustainable Landscape Design (Continued on page 22)

The Bug Doctor bleached effect and later, the leaves turn yellow, gray or bronze. Complete defoliation may occur if the mites are not controlled. Southern red mites first attack the lower leaf surface. As the numbers increase, mites move to the upper surface. Injured leaves appear gray. Six-spotted mites feed along the midrib on the underside of the leaf, and the upper surface has yellow spots. When heavy infestations occur, the entire leaf becomes yellow, distorted and drops prematurely. Spruce spider mite feeding causes the plants to appear off-color and eventually turn completely brown when high numbers are present.

Mites Three major groups of mites attack ornamentals: spider mites, false spider or flat mites, and gall or eriophyid mites. Mites are not insects. The body of spider mites and false spider mites is separated into two distinct parts: (1) the gnathosoma and (2) the idiosoma. The gnathosoma includes only the mouthparts. The idiosoma is the remainder of the body, and parallels the head, thorax and abdomen of insects. The first immature stage (larva) has three pairs of legs. However, nymphal stages and the adult have four pairs of legs.

False spider mites have no webbing. Damage from these mites varies considerably, ranging from faint brown flecks to large chlorotic areas on the upper leaf surface to brown areas on the lower leaf surface, depending on the host.

Spider mites are the most common mites attacking plants. False spider mites and eriophyid mites are less common. Eriophyid mites exhibit great modification of body structure. They have only two pairs of legs; the four rear legs are absent. They are microscopic, elongate, spindle-shaped and translucent, and the abdomen usually has transverse rings present. Female spider mites lay several hundred eggs. Eggs are attached to the fine silk webbing and larvae hatch in approximately three days. The live stages include the egg, larva, two nymphal stages (protonymph and deutonymph) and adult. At 80 F, spider mites complete their development in five to twenty days. There are many overlapping generations per year.


The majority of eriophyid mite species go through four stages of development: the egg, two nymphal instars and the adult. The length of the life cycle is variable, but is usually approximately seven days. 3 Two-spotted spider mite (figure 3) prefers the hot, dry weather of summer and fall, but may occur anytime during the year. Southern red mite populations are at their peak during the winter months under mild, humid conditions. They can be found year-round, especially on shaded or stressed pyracantha. They usually disappear when the new spring growth develops. The six-spotted spider mite is most abundant during winter and spring on azalea, especially after a cold winter. Spruce spider mites occur during the hot, summer months, especially on plants under water stress. False spider mites and eriophyid mites occur throughout the year, but predominantly during the summer and fall.

Mites have needlelike piercing-sucking mouthparts. They penetrate the plant tissue with their mouthparts, and are found primarily on the underside of the leaf. All spider mites spin fine strands of webbing on the host pant. Two-spotted spider mites remove the sap, the mesophyll tissue collapses and a small chlorotic spot forms at each feeding site. An estimated 18 to 22 cells are destroyed per minute. Continued feeding causes a stippled,


Eriophyid mite feeding results in the following damage symptoms: (1) russetting of leaf and fruit (citrus); (2) leaf galls (juniper); (3) leaf blistering on top with hairy growth underneath (black olive); (4) discolored and stunted terminal growth (podocarpus); and (5) discolored bud scales, floral parts and leaves (camellia). These mites are thought to possess chemicals in their salivary secretions that act as growth regulators. When the mites feed, these chemicals are injected into the plant. Leaves may become discolored or plant growth patterns may be changed. Modifications of plant tissue are initially more readily found on embryonic plant tissue. Russetting, which is discoloration, occurs on mature leaves and fruits. Eriophyid mites induce plant galls from epidermal cells that are injected with growth regulators. Each mite has particular chemicals that cause galls to form which benefit the mite. After the induced change has altered the behavior of cells, the mite does not have to remain on the site to insure continuation of gall growth. Eriophyid galls occur on soft plant parts, usually on green tissue. Galls occur in many different shapes: pouch or purse galls, bladder galls, nail galls, finger galls and head galls. For detection of spider and false spider mites, use a 10X to 15X hand lens. Look at the undersides of the leaves. Put white paper or a white paper plate beneath the leaves, and strike the foliage sharply. Mites will fall onto the surface, and are more easily seen. Eriophyid mites are so small they are virtually impossible to see without a microscope and a trained eye. If damage symptoms indicate a possible infestation, take the affected plant parts to your county extension office. There are several components to managing mites. Scouting is (Continued on page 24)

PLANTS‌ A PATHOLOGISTS’S PERSPECTIVE ARMILLARIA ROOT ROT Armillaria root rot (also called shoestring root rot) is a devastating disease that occurs on a wide variety of shade and fruit trees, vines, shrubs, and a few herbaceous plants. Recently it has been involved in the decline of older plantings of landscape roses in Louisiana. Although the disease is usually attributed to the soil-borne, root-infecting fungus, Armillaria mellea, there are dozens of closely related species of Armillaria that cause similar diseases. In the southeastern U.S., the fungus primarily responsible for this disease is Armillaria tabescens (formerly Clitocybe tabescens) and the disease it causes is commonly referred to as mushroom root rot or Clitocybe root rot. Like other species of Armillaria, this pathogen is normally associated with hardwood forests and is found in urban landscapes where previously wooded areas have been cleared for development. Armillaria is also called the honey fungus because of the color of the mushrooms that it produces, and the oak root fungus because it is commonly associated with the roots of oak trees from which it may spread to other more susceptible hosts. In landscape plantings the disease may not be noticed until the fungus reaches and girdles the crown of highly susceptible plants resulting in their rapid decline. Subsequently as the pathogen spreads, nearby plants may also be killed. On less susceptible hosts, symptoms may develop more slowly and are typical of those caused by root rot pathogens in general. However, careful scraping of the bark from the root collar of the tree or shrub reveals the white fungal mycelium that is a characteristic sign of this disease (Fig. 2). Excavation of the roots may also reveal the presence of dark, shoestring-like fungal structures called rhizomorphs, but these are not commonly associated with A. tabescens. Following wet weather in the fall, clusters of honey-colored mushrooms are produced at the base of plants infected by A. tabescens, as well as beside stumps colonized by the fungus. Clusters of mushrooms are often observed in lawns growing from infected or decaying roots in the soil (Fig. 1). These fungi are opportunistic pathogens and active decom-


posers of trees and other woody plants. They are capable of surviving in tree stumps and large infected roots buried in the soil for many years. They become active and initiate hyphal growth when roots from a new tree or shrub come in contact with the infested roots. As the pathogen colonizes the new host roots by growth along and through the root, it also spreads from plant to plant through root-to-root contact or by the growth of the fungus through the soil by means of the rhizomorphs. Little can be done to control this disease once it becomes established and no fungicides are available for its control. One management practice, that may help, is to avoid cultural practices such as irrigation and mulching that keep the base of the plants wet as this creates an environment that favors pathogen growth. The excavation of soil from the root collar is a recommended practice if only a few roots and a small portion of the root collar are infected as this promotes drying of these tissues, which prevents further growth of the pathogen.

Southern Nursery Association:

REBUILDING THE MARKETPLACE Oak Grove, VA, October 10, 2011 – The Southern Nursery Association (SNA) is moving beyond the small steps it has taken over the past few months to rebuild the association and has begun taking larger steps to focus on rebuilding the marketplace in the Southeast.

with a robust search engine for locating people, products and services, as well as more than 10,000 pages of horticultural research. Member forums, blogs, and email alerts add to the functionality of the new system.

Founded in 1899, the SNA was a prominent industry leader for more than 100 years. After a transition of leadership in 2006, and several years of economic downturn, coupled with industry consolidation, a decline in membership and the cancellation of the annual SNA trade show, the 112-year old association found itself in a downward spiral and a stagnant condition. In November of 2010, Danny and Karen Summers, who served the association from 1988 to 2006, contacted the current board of directors and a core group of past presidents and members to encourage them to pull together to save the association.

To assure regional participation and input, several new committees have been created and will be functioning soon. These new committees will assist with efforts to provide communication, education, information and marketing opportunities throughout the region. In addition, the annual SNA Business Meeting and SNA Research Conference have been scheduled and will be held in conjunction with the GSHE in Mobile, AL in January of 2012. A special roundtable discussion, exploring ways to stimulate the marketplace to create more business opportunities in the Southeast is planned to take place during this time. More details to follow.

In February of this year, Karen Summers was appointed Interim Executive Vice President. Danny Summers was appointed Board Advisor. Since then, the group has been hard at work to set new directives for organizational change to rebuild the association and once again become an integral part of the horticulture industry in the southeast. The future focus will be on member services to promote sales and profitability, and monitoring issues that cross state lines and impact the region. Taking advantage of the digital age, vital industry services, current news and relevant information will be delivered online through the new SNA website ( The new website features a virtual marketplace


You can expect to see many changes and lots of activity in the coming months with the launch of the new website, new committee development, member surveys, regional news and information disseminated once again, and industry leaders recognized through the SNA awards program. The Southern Nursery Association is a non-profit, professional trade association representing the horticultural industry in the southern U.S. SNA provides member services to wholesale growers, brokers, retailers, landscape contractors, landscape architects, (Continued on page 5)

lower portions of the weed. For example, pink woodsorrel (Oxalis debilis) mainly infests flower beds and has underground storage organs that prevent effective hand removal. When practical, I would consider wiping the weeds with a 10% glyphosate solution. Glyphosate will translocate through the woodsorrel leaves into the stolons and rhizomes and successfully destroy the plant. Asiatic hawksbeard (Youngia japonica) - Asiatic hawksbeard is an annual broadleaf that is a problem year round in landscape beds and nursery crops. However, I see it most often in the fall in the gulf south area. Very rarely do I see a flower bed in the fall and winter that is free of hawksbeard. The weed features spatulate leaves that are lobed along the edges. It also has a long flowering stalk and it has a short taproot that allows for easy hand removal. When in bloom, Asiatic hawksbeard features flowers that are yellow in color and have five tiny teeth at the end of outermost petal. Seeds are dispersed by the wind just like dandelion.

Program. This program is published by the United States Green Building Council / The American Society of Landscape Architects ASLA & Partners and is available now for use by landscape architects. One other thing that might be related to landscape sustainability is to include, in the draft code, that written specifications with landscape plans ought to include the sustainable gardening standards as published by the LSU AgCenter in the Louisiana Yards & Neighborhood (LAN) Program.

Dollarweed (Hydrocotyle spp.) – Dollarweed is a creeping perennial in the same family as parsley. The weed reproduces vegetatively and by seeds. I see this plant often in irrigated flowerbeds and in neglected nursery containers. It likes wet areas but will linger once established even after the irrigation has been removed. Unfortunately, hand removal is about all that we have in sensitive container crops. This is marginally effective because most often parts of the plant will be left behind leading to reestablishment. In some situations, you may just be better off to re-pot the plant and start over. In landscape beds, hand removal and repeated applications of imazaquin (Image) can help. Imazaquin doesn’t blow dollarweed away but helps suppress the weed with follow-up applications. Check the Image label for tolerant plants. Repeated applications of glyphosate will suppress dollarweed as well. Good thick mulch helps suppress dollarweed but more than likely, you will find yourself hand weeding this plant in landscape beds.

Catchweed Bedstraw (Galium aparine) – Bedstraw, a winter annual gets its name because of one of its most well-known uses. In the medieval times, the plants were dried to stuff beds and mattresses. This is the first landscape code in the State of Louisiana to Often the plant is called “Velcro” weed because it has spines at the base of leaves that allow bedstraw to cling to objects. The leaves of promote landscape sustainability and one of the best, of the bedstraw are formed in whorls containing 6 - 8 leaves around square very few, that have started to develop in locations such as stems.

After some discussion Pete Newton moved, seconded by Gerritt Monk to accept the financial report as presented. Motion carried. Todd asked Pat Newman to give the GSHE report. Pat stated that there will be a November 10, 2011 meeting and she will get updates at that meeting. It was asked if James Harwell had received the membership list yet. Severn stated that he sent the list to James on August 13, 2011 and he reconfirmed that it was alphabetized by company name not by person’s name. Todd asked Severn for a membership report. Severn stated that he had received 3 rd quarter figures from Laura and they included: 2 memberships at the $50.00 level, 2 @ the $75.00 level, 4 @ $150.00, 6 @ $100.00, 8 @ $25.00, 4 @ $15.00 and 9 student applications for a total of 35 memberships in the 3rd quarter (25 new and 10 renewals). The total for the year was 474 with 108 new memberships according to Laura’s figures. Severn then gave his figures which included: 96 growers, 41 retailers, 99 landscapers, 28 associates, 24 affiliates, 48 gov/ed, 42 students, 2 sod, 7 arborists, 18 landscape architects and 21 honorary members. Total membership as of October 11, 2011 was 426 with 363 paying members. Severn reminded everyone that he counted memberships by category when he received a membership application or renewal. Some discussion ensued as to the discrepancy and Allen stated that Laura may not have purged all previous students and none of the 21 Honorary Members were listed in Laura’s figures. Pete then asked Allen Owings for an LSU AgCenter update. Allen indicated that the AgCenter was still undergoing a budget deficit and some AgCenter personnel were given ‘pink’ slips due to downsizing of personnel. The Super Plant for fall was ‘Belinda’s Dream’ rose. The education program occurred at 11:00 A.M. till noon with Allen conducting a tour of the Hammond Research Station. Todd then moved to Old Business and asked if there were any new funding requests. Severn indicated that he had received a letter from ANLA requesting LNLA to return a Lighthouse Partnership Participation form and invoice with a payment assessment of $10.00 for each active LNLA member for 2011 which would amount to either $4,740.00 or $4,260.00 depending upon whose figures were used. Much discussion ensued. Someone asked how the Lighthouse fund appeared on the new Membership Renewal form. At that point Severn handed everyone a copy of the new Renewal form. More discussion ensued and finally Nick Simoneaux moved, seconded by Robert ‘Buddy’ Lee, to take out the Beacon Fund option on the new Membership Renewal form and leave the Lighthouse Fund option at the $36.50 level and send a letter like we did last year encouraging members to contribute voluntarily to the Lighthouse Fund. Motion carried but with two descenting votes, Mark Murrell and Gerritt Monk. Todd moved to the Membership report and indicated that the Membership Drive would be held at Perino’s Garden Center on October 19, 2011 in conjunction with the New Orleans Horticulture Society and 390 letters of invitation were sent out. Todd Asked Pete Newton to report on the Nomination Committee. Pete indicated that they were still working on the nominations and would have it prepared by the December 7th meeting. Todd asked Allen to report on the Website Committee. Allen stated that the redesign was almost complete and the site looked good. It was asked who contributed information for the website updates and Allen said that he and Severn were responsible for getting Sophie updated material. Pat Newman requested that Severn ask Sophie to provide an itemized billing with the number of hours spent on each project. Severn requested that of Sophie on October 18, 2011. Severn said that the page views for July, August and September were13,684, 20,410 and 18,017, respectively. (Continued on page 24)

Todd asked Pete Newton to report on the Newsletter Committee. Pete stated that he was pleased with the newsletter and asked Severn to continue with it the way it had been with the 3rd quarter newsletter. Todd asked Pat Newman to report on the Organizational Committee. Pat handed everyone a copy of the revised report and stated that she had asked Laura and Severn for input on their respective duties. They both responded. Todd stated that the job description of the Executive Secretary was not finalized and would be finalized with the help of the Review Committee and the Executive Secretary. Todd indicated that an Executive Secretary Review Committee comprised of the President, Vice-President, Past President and Allen Owings would convene between now and the December 7th Board Meeting to assess the job performance of the Executive Secretary. Todd moved to Old Business and asked Chris Bass for a Meadowbrook Insurance update. Chris indicated that Meadowbrook had hired a new agent to work North Louisiana and that he was planning to attend GSHE. After the Board meeting Severn received a 3 rd quarter check from Meadowbrook in the amount of $875.00. Todd asked Gerritt Monk to report on the CENLA Work Ready Network and Gerritt responded that the program was on hold because the Network could not find a sponsor. Todd moved to New Business and asked the Board if there was a motion to pay Annie Coco’s expenses to attend and help Severn with the GSHE Booth again this year. Pat Newman moved, seconded by Margie Ann Jenkins to pay Annie’s expensed to attend the GSHE Show in 2012. Motion carried. Todd asked Severn to discuss the landscape architecture continuing education CEU’s. Severn stated that he had received a form from Craig Roussel and if any landscape architects attended the CNLP or other training, Severn could justify the number of CEU hours and sign the form. Todd indicated to the Board that he emailed all Members of the Board and got 8 favorable responses to make a $250.00 political contribution to Commissioner, Mike Strain’s re-election campaign. But before any contribution was made, Severn checked with Susan Webb, CPA to determine if LNLA, being a 501 (c) 5 organization could make political contributions. Susan indicated that LNLA was legal in doing so as long as it did not constitute the organizations primary activity. Pat then sent the check to campaign headquarters. Todd asked Craig Roussel for an LDAF update. Craig thanked the Board for the campaign contribution and also thanked the board for paying up to $600.00 for him and Ansel Rankins to attend and set up an LDAF exhibit at the GSHE Show. They really enjoyed going in the past and appreciated the LNLA travel funding support. Severn asked to make an announcement by stating that the new CNLP dates have been established. He and Dan Gill have set the dates for March 1, 2, 2012 at the Hammond Research Station and August 2, 3, 2012 at the Ira Nelson Horticulture Center in Lafayette. The classes will begin at 9:00 A.M both days at the two sites. Todd asked Allen Owings to report on the Foundation Meeting held earlier in the morning. The Minutes of that Meeting will be posted along with these Minutes on the LNLA website and in the newsletter. Pat Newman announced that Regina Bracy submitted a nomination for she, Allen Owings, Dan Gill and Elma Sue McCallum for the Denver T. and Ferne Loupe Team Award for the Louisiana Super Plants Program. The award recognized excellent Extension programs that have parish, regional, state or national impact. The Louisiana Super Plants Program won the award! Congratulations to Regina, Allen, Dan and Elma Sue for this accomplishment. There being no more business, Gerritt Monk moved, seconded by Rick Cicero, to adjourn the Meeting. Motion carried and the Meeting concluded at 3:10 P.M. Mites (Continued from page 12)

very important. Predatory mites include Mesoseiulus longipes, Neoseiulus californicus, Neoseiulus fallacis, Phytoseiulus macropilis, and Phytoseiulus persimilis. Resistance management is important, and different classes of insecticides should be rotated to reduce the risk of developing resistance. Insecticidal soaps and oils should be considered, but care must be taken not burn the plants. Most miticides are not effective on mite eggs. Miticides may be required at 5 day intervals during the Summer and 7 day intervals in the Winter. Some miticides that may be used for spider mites or broad mites (fig. 1, pg. 12) include: Avid 0.15 EC, Kelthane 35% WP, Malathion (57% EC), Mesurol 75 WP, Talstar 10 WP, Floramite 50%, Conserve SC, Ornamite, Ultra fine oil, Judo, Ultra pure oil, Ovation SC, Forbid 4F, Kontos, Pylon. Make sure the product is labeled for the plant and mite. Some miticides for rust mites (fig. 2, pg. 12) include: Pylon, Kelthane 35% WP, Sevin 2T, Morestan 4F, Ultra pure oil. Make sure the product is labeled for the plant and mite. Article provided by: Dr. Dennis Ring, Professor of Entomology, LSU AgCenter, (P) 225-978-3881, (E)

Case No. 11-010: Three violations of L.R.S. 3:3804 (C) for soliciting and engaging in a regulated profession (arborist) without the proper license. Fined $750. In FY 10-11, the Horticulture Commission administered 705 exams and issued 5,970 licenses, 1,498 Nursery Stock Dealer Permits, and 1,000 Cut Flower Dealer Permits. In quarantine related programs for FY 10-11, we issued 671 Nursery Certificate (Grower) Permits and 43,797 nursery shipping tags. There were 181 inspections for Imported Fire Ant certification for shipments to other states, two Post Entry Quarantine inspections for nursery stock imported from other countries, and 424 compliance inspections of nursery stock shipped into Louisiana from other states for pests such as brown garden snail, lethal yellowing of palms, pine shoot beetle, gypsy moth, citrus pests, burrowing nematode, and sudden oak death. Twelve statewide surveys were completed for non-indigenous pests. These included pests such as Emerald Ash Borer, Japanese Beetle, Gypsy Moth, Pine Shoot Beetle, Citrus Pests, Light Brown Apple Moth, Sudden Oak Death, and Nematodes, all of which are pests of ornamental plants. No new significant new pest was found in Louisiana. There were 11 plant pest quarantine related investigations conducted during FY 10-11. Of those, three involved improper certification of nursery stock from other states. One case was a shipment of ornamental sweet potatoes that arrived from Alabama without certification. Shipment was placed under a stop order until certification was received. One was a shipment of ornamental nursery stock from California that did not have the federal Sudden Oak Death certification accompanying the shipment. Proper certification was obtained and plants were released for sale. The third case was a shipment of palm trees from Texas without certification for Texas Palm Decline. Certification could not be obtained for this shipment; plants were confiscated and destroyed.
