t’s a murky winter morning. It is the sort of day when my lazy gene rages, encouraging me to lay around in sweats. It would be absolutely marvelous to surrender to the impulse, grab a cup of tea and comb seed catalogs. Giving in to the urge, however, will undoubtedly set a pace for the day, making it nearly impossible to accomplish anything. Of course, we all could use a down day (or two) right about now. From the shrill of national events that has seeped into our brains, to the international atrocities that plague our very souls. And the intense end-of-the-world social conversation is psychologically exhausting, a fatigue that seems longlasting. Like my gardens, I’m more dormant than awake this time of year. Truthfully, I’m a little more vulnerable and a little less strong in the winter. In any other season, this would not seem as compelling. The garden would be my escape, my respite. I would be committed to a list of activities that keep me busy, mind and body. Since we’re in winter’s grip, and time in the garden is mini-

mal, a day on the sofa sounds like a great idea. Maybe what we need is a revival, a day filled with puppies and kittens, ice cream and chocolate. That sounds like a happy solution, does it not? I mean, who doesn’t love kittens? Never mind, I don’t want to know. Oh, but wait, what if you’re allergic to cats and dogs and dairy and sugar (how dreadful), then what? Perhaps birding is the answer. The 20th Annual Great Backyard Bird Count is held this month, February 17-20. Bird watchers of all ages count birds to create a real-time snapshot of where birds are. Anyone can take part, birders of any level or a feeder watcher. Individuals, families, friends, schools and organizations are all invited to count birds in their backyards, local parks or wherever you happen to be. Please visit the official website at www.birdcount. org for more information.

Another option is to join Alan Branhagen for a bird hike at Powell Gardens on February 19. See the details listed in Powell Gardens events on page 15, or visit powellgardens. org/walkwithnature to learn more and register. Speaking of birding, have you joined millions to watch the live Eagle Cam? There is a Bald Eagle pair in southwest Florida that bird lovers everywhere have had the privilege to observe. From the viewers’ vantage point, we are able to witness the pair build their nest, care for each other and their eggs, and the miracle of an eaglet break free from its shell. What a remarkable journey. And to all who make this possible, I am grateful! Nature inspires, gently nudging me along through winter. I’ll keep my feeders full and binoculars close, so not to miss the next miracle. I’ll see you in the garden!

Gardening under a Black Walnut Grove


early 18 years ago I planted two fringetrees (Chionanthus virginicus) in the Whitmire Wildflower Garden at Shaw Nature Reserve in Gray Summit, MO. I planted one 10 feet from the base of a mature black walnut tree (Juglans nigra), the other beneath a chinquapin oak. It has been interesting to watch them grow over time. The one beneath the oak is approaching 15 feet in height and spread whereas the one under the walnut is both five feet tall and wide. Both have attractive branch structure and flower well. The dwarfing effect comes from juglone, a chemical produced by walnut roots. I’ve seen the same effect of juglone on two other smallflowering trees, common witchazel

(Hamamelus virginicus) and prairie crabapple (Malus ioensis). This dwarfing affect looks pleasing on single or multi-stemmed trees, but it can make certain shrubs look scrawny. They have fewer stems, are not filled out well and invite weeds. Black chokeberry (Aronia melanocarpa) and swamp dogwood (Cornus amomum) are two shrubs that do poorly under walnuts for this reason. On the other hand, wild hydrangea (Hydrangea arborescens) and beautyberry (Callicarpa americana) are virtually immune to the black walnut potion. They are full and perform beautifully. Grasses and sedges also do well under the black walnut spell. Star sedge (Carex radiata), fox sedge (C. vulpinoidea), cedar sedge (C.

eburnea), and Pennsylvania sedge (C. pennsylvanica) all grow nicely in black walnut shade. So does American beakgrain (Diarrhena obovata; a suckering grassy groundcover), and river oats (Chasmanthium latifolium), a grass that seeds around aggressively. Giant cane (Arundinaria gigantea) is in the grass family. Under walnuts it is easier to control and its growth rate is notably slower, a nice trait for a plant that is notoriously aggressive. Perennials growing under black walnuts are a mixed bag. Rose turtlehead (Chelone obliqua) does well but Joe-pye weed (Eupatorium purpureum) doesn’t. Neither does American alumroot (Heuchera americana), but prairie alumroot (Heuchera richardsonii) and little-flower alumroot (H. puberula) grow perfectly well. Barren strawberry (Waldsteinia fragarioides) grows densely and flowers well, but is a slow-grower no matter where it grows. Southern blueflag iris (Iris virginica) grows strong and flowers decently though it flowers better in full sun, while copper iris (Iris fulva) performs poorly altogether. I garden under a black walnut at home too. Beneath it is a patch of wild sweet William (Phlox divaricata), elephantsfoot (Elophantopus carolinianus) and blue-eyed Mary (Collinsia verna, an annual) that thrive and spread. Though I like the shade the tree provides, their nuts are a bit of a nuisance. When the wind picks up in early fall they come crashing down on the roof

like baseballs. THUD, THUD and THUD! On the ground they are trip hazards so need to be raked up. Fortunately we have a handy gizmo on a pole that rolls over the round fruits, gathering them up as you go. It makes the job easier. If you eat black walnuts the first step involves removing the outer hulls by placing them on a driveway. Drive over them with your car for a few days. The hulls come right off. Then let the inner nuts dry out for a month or two before cracking them open to pick out the nutmeat. My former colleague Ray Garlick showed me the ropes. I miss old Ray. He had a nut-cracking stump that had several indentations (that hold the nuts in place) from decades of whacking them gingerly with a hammer. He once told me that he watched a squirrel throwing walnuts in the air one after the other while listening to the sound they made when they hit the ground. A good thud meant a good nut and off he went stashing it away for winter. So don’t waste another moment reading this, get outside and experience what is happening in your own backyard or neighborhood! You can find suppliers of native plants at www.

Ask the Experts Readers share their questions about landscape issues, and DENNIS PATTON gives expert tips and advice. BOXWOOD BLIGHT Question: Over the holidays I read about making boxwood wreaths. The article said you should not bring home purchased boxwood sprigs if you have boxwood planted in your yard. They said it could lead to boxwood blight. What is boxwood blight and should I be concerned? Answer: Boxwood blight is a nasty disease of this popular plant. It has been detected in the Kansas City area in a local nursery several years ago; the plants were recalled and destroyed. At this writing I know of no major outbreak of the blight in the Kansas City area landscapes. K-State wants me to continually check and send samples into the lab to confirm if it is present in the landscape. Prevention is the key to controlling this disease

No known outbreak of boxwood blight in Kansas City landscapes at this time.

The effect of acorns on soil pH occurs over a long period of time.

Fertilize azaleas when growth begins in spring or just after flowering.

which means the plants should be removed and destroyed. Checking several websites where blight is a major issue they do warn about purchased décor that contains boxwood. They indicated it could be a transmission source.

They recommend either not purchasing or keeping the items away from boxwood in the landscape. When discarding, double bag and never compost. Should you be concerned? Yes, there is a potential for this disease to become more widespread. If you do use just keep it away from the garden plants and tucked more safely in the home.

years there will be an effect, but how much? Remember, our soils tend to run on the high side so the lowering effect of the acorns may be beneficial. Keep in mind in most cases the pH can drop by a couple of points and still would be in an acceptable range for most plant growth. Let me bottom line this question. There are so many things in life more important to worry about. If you are really concerned then take a soil test (a reliable one) and you will know for sure.

ACORNS AND SOIL PH Question: I had a lawn service tell me acorns from my pin oak change the pH of the soil under the tree. Is this true? Answer: Acorns tend to have an acidic pH. Yes they can lower the soil, but this is not a short term effect; it is a long, very long term effect. Even though I answered yes the real answer is not in your lifetime or probably the following generation. Maybe in 50 or 100

RHODODENDRON AND AZALEA FERTILIZER Question: Do I need a special fertilizer for my rhododendrons and azaleas? Should I apply it in February? Answer: If I am selling you fertilizer of course the answer is yes. But really all you need is a general

Set broccoli plants in the garden mid to late March. plant food which can be used on just about every plant in the garden. Each established plant probably needs no more than a quarter cup or so. As for when, I would say either when growth begins in the spring or just after flowering. Keep this in mind. Fertilizer may not be needed if the plants are growing strong and healthy. Also fertilizer does not make an unhappy plant happy; it does not correct issues with location, drainage, or other factors. It can help healthy plants grow bigger and stronger; however, fertilizers can actually make a sick plant suffer more. Fertilizers are a tool for plant growth not a salvation. They do not perform magic! GROWING BROCCOLI FROM SEED Question: I’d like to try my hand at growing broccoli from seed. When should I start my seeds? Is sunlight from a south window sufficient to produce healthy plants? Answer: Growing broccoli can be fun and rewarding. Transplants can be started at home. They will require about six to eight weeks to develop into a nice size transplant for the garden. The ideal time to

set broccoli plants in the garden is mid to late March. Seeding should take place in early February for best results. Sufficient light, now that is the challenge. Rarely is a south window bright enough for a strong transplant. They tend to be taller, leggy and not as stout. Growing transplants under shop lights is the best method as they provide the intensity and duration needed for healthy plants. Transplants also NEW S240can SPORT be found on the market at that time if you don’t want to start the plants from seed. But give it a try and see what happens. NEW S240 SPORT

Bird of the Month: Eastern Bluebird Attention birders! THERESA HIREMATH reveals her plan to attract these happy birds and how you can too.


ho needs a little more happiness in their lives? Everybody, that’s who! No other bird brings me more happiness than the delightful Eastern Bluebird, and my mission this year is to attract them to my new home. Luckily, Bluebirds are quite happy to live near our homes, preferring open fields (lawns) surrounded by tree and shrub borders. The fields and lawns provide the insects that Bluebirds love to eat, and the trees and shrubs surrounding the lawn provide shelter and a perch from which they can hunt. To attract any bird, we need to provide food, water, shelter, and a place to raise their young. To attract Bluebirds, specifically, I’ll put up a Bluebird house by midFebruary for shelter and a place to raise their young. As soon as the

house is up, I’ll begin feeding live mealworms on a reliable schedule in a readily seen mealworm dish or tray feeder. Already in place are several birdbaths with heaters to ensure my birds always have water. Because Bluebirds are one of the earlier nesting species, February is a great time to install a Bluebird house so that it is available for spring inspection and habitation. To reduce competition from house wrens (who don’t like to travel over open spaces) Bluebird boxes should be placed 25 feet or more away from cover. Houses mounted at eye level, make it easy for you to monitor the nest. Snakes and raccoons are known predators of Bluebird nests, so be sure to baffle the house or install a snake guard. Bluebirds need elevated perches from which they hunt, frequently

using the top of their house and surrounding trees as perches. When an insect is spotted, they drop to the ground to capture it with their bill. This sit-and-wait technique is called drop-hunting. A Bluebird can spot caterpillars and insects in tall grass at the remarkable distance of over 50 yards. During fall and winter, they perch in fruiting trees to eat berries. Bluebirds love mealworms, live or dried, and the ideal food to lure Bluebirds to your area. As the days grow longer in the spring, the male begins his mating song. Along with his song, the male attracts a mate by bringing nesting material in and out of the nesting hole, perching near the site, and fluttering his wings. Males may carry nest material to the nest, but they do not participate in the actual building. They spend much time guarding their mates during this time to protect the nest from other birds and to prevent the female from mating with other males. Bluebirds are generally monogamous, staying together throughout the breeding season, and they may breed together for more than one season. Both sexes defend territories, however, the males tend to defend territory edges while the females primarily defend the nest site. Only the female incubates the 4-6 eggs which she maintains at a temperature of 98-100°F. Nesting occurs from March through August, and Bluebirds may raise two and sometimes three broods per season. Pairs may build their

second nest on top of the first nest or they may nest in an entirely new site. To improve survival rates for the second or third brood, I’ll remove the nest from prior broods. If you leave the previously used nest, subsequent broods may fledge too soon due to excessive nest height. The male continues to take care of the recently fledged young while the female begins to re-nest. Young of the first brood will occasionally help raise their siblings in the second brood. Families flock together until fall. At that time they merge with other family flocks. Bluebirds rarely winter in areas where night-time temperatures routinely fall below 20°F. For those that do stay through winter, the Bluebird house will be used for roosting. To protect them through chilly winter nights, I will cover the vents to seal in warmth. Then remove the sealing material once it warms up in spring. Adult Bluebirds tend to return to the same breeding territory year after year, but only a small percentage of young birds return to where they were hatched. Bluebirds consume about four grams of food per day, or about 12 percent of their body weight. This is equivalent to a 200 pound human eating 24 pounds of food each day! In addition to mealworms, Bluebirds also love suet, sunflower hearts and finely ground sunflower, and fruit, which can be placed in a tray feeder or tube feeder with a tray attachment. The Eastern Bluebird’s willingness to use nesting boxes and their love of mealworms provide excellent opportunities for you to attract these lovely creatures to your area. If you’d like to try attracting them, or have any other questions, call or visit our store. Our backyard birdfeeding experts would love to help!

Lakeside Serenity By Terry Blair Michel


magine a beautiful lakeside setting with an adjoining garden having a wide variety of landscape features including trees, shrubs and blooming plants along with perennials and handmade glass whimsies. This is one of several garden homes featured during the Master Gardeners of Greater Kansas City Garden Tour, June 9 and 10, 2017.

The owners have kept in mind yearlong blooms and pollinators, as well as various shapes of trees, as they planted their garden. Their desire to also have “something green” all year shows in their fascination with different and distinctive evergreen varieties planted throughout the yard. Landscaped berms have been positioned in the back yard to accentuate the view of a beautiful fountain in the lake. A small greenhouse is tastefully tucked along side of the house for the owner’s pleasure. It has a watering system that has helped the owners to store tropical plants and start plants during the winter and early spring. Vegetables are kept in containers to keep the deer at bay in warmer seasons since they are prevalent in the area and love vegetation.

Despite the thick clay soil, the owners have put in a drainage system, and with the use of the various berms have been able to maintain a beautiful landscape. They have used wood mulch which helps the soil become enriched as it disintegrates. Many native perennials, which are hoped to be deer-proof are used in the berms as well. Some of these are black-eyed Susans, coneflowers, coreopsis, beard’s tongue, monarda, agastache, and yarrow for color.

ZINNIA Profusion Red


All-America Selections 2017 Flower Winners

ll-America Selections, the only non-profit trialing organization for plants that demonstrate great garden performance throughout North America, presents 11 exciting new AAS Winners for the 2017 garden season. We’re featuring the flowers this month, the vegetables in the March issue. Each of the following varieties was trialed in North America by professional, independent, volunteer judges during one growing season. Each was trialed next to comparison varieties that are considered best-in-class among those currently on the market.

CELOSIA Asian Garden This spiked beauty claimed victory in North America’s trial sites to become the first ever AAS Winner from Japanese breeding company Murakami Seed. The judges gave this entry high marks in the greenhouse for the good branching, almost bushy growth habit and early to bloom flower spikes. In the garden, Asian Garden Celosia continued to bloom on sturdy stems, keeping the bright pink color all summer long, holding up even through some of the first frosts of the season. The AAS Judges commented on the fact that this celosia was a pollinator-magnet, making this AAS Winner a sure bet for pollinator-friendly gardens. ZINNIA Profusion Red This newest Profusion Zinnia winner is the fourth color in the single flower series to win the coveted AAS Winner award. The original Profusions were ground-breaking

plants because of their compact form, disease resistance, early and continuous blooms all season long and ease in growing. Judges raved about the vibrant, perfectly true red color of this zinnia which doesn’t fade in summer’s intense rays. As one judge stated, “We have waited for years for this true red color in zinnias!” Gardeners will find many uses for the true red zinnia that’s easy to grow and a favorite of pollinators.

VINCA Mega Bloom Pink Halo F1 Mega Bloom is an exciting new series of vinca bred to withstand heat and humidity without succumbing to disease. Pink Halo produces huge soft pink blossoms with a wide white eye. These flowers present a striking look in the garden, even from a distance. Plants maintain a nice, dense habit with flowers staying on top of the foliage for full flower power color. VINCA Mega Bloom Orchid Halo F1 Mega Bloom is an exciting new series of vinca bred to withstand heat and humidity without succumbing to disease. Orchid Halo produces huge bright rich purple blossoms with a wide white eye creating a striking look for the garden, even from a distance. Plants maintain a nice, dense habit with flowers staying on top of the foliage for full flower power color. VERBENA EnduraScape™ Pink Bicolor EnduraScape™ is described as “tough as nails” because it is the first verbena that can toler-

ate drought and heat plus survive cooler temperatures down to the low teens. This long-blooming pink bicolor verbena is spectacular in the landscape, edging a walk or border as well as in large containers and baskets. Vigorous plants are sturdy spreaders that pop with abundant soft pink blossoms that darken in intensity toward the center of the bloom. Pink Bicolor is the newest color in the series and the AAS Judges deemed it truly spectacular! PENSTEMON Twizzle Purple Vibrant purple blooms present a new and unique color in penstemon! Twizzle Purple was judged as a first-year flowering perennial by judges who were impressed with the upright plant habit and superb flowering performance. This North American native blooms profusely with 1-inch tubular flowers on long slender stalks that grow up to 35 inches high, making this beauty a magnet for pollinators from mid to late summer. Twizzle Purple can be used to add height to combination planters or in landscapes for highimpact color.

GERANIUM Calliope® Medium Dark Red With an outstanding deep red velvety flower color and great branching habit, Calliope® was unmatched in the AAS Trials when compared to other market varieties. Calliope® Medium Dark Red geranium is an interspecific hybrid with zonal-type flowers and leaves. This AAS Winner has a mounded, semi-spreading growth habit with strong stems supporting the flower

heads that are loaded with deep red blossoms. These plants work great in containers, combination plantings, hanging baskets as well as in an in-ground landscape. Gardeners will enjoy exceptional landscape performance in normal conditions as well as in more challenging high heat and drought conditions. DIANTHUS Interspecific Supra Pink F1 Supra Pink joins its sister, 2006 AAS Winner Supra Purple, to give us two fantastic colors in an easyto-grow interspecific dianthus for three-season (spring, summer, fall) garden color. This compact, bushy plant blooms prolifically with novel mottled pink flowers sporting frilly petal edges that hold up even in summer heat and drought. No deadheading needed on this winner. One judge attempted to deadhead this entry but it rebloomed too fast to do so! Supra Pink grows to just under a foot in height but is a vigorous grower and will deliver fancy, clear pink flowers for a long time as observed over and over by the AAS Judges. Supra Pink was tested as an annual and won the award based on firstyear performance, but similar to other dianthus, it may overwinter in some regions. Keep in mind that these award winning plants might not be readily available at your local garden center this season. So secure this page and add these newbies to your wish list of plants.

Tips on Fertilizing Landscape Trees Soil tests, and evaluating tree vigor are elements that LALA KUMAR considers when fertilizing trees.


deally, soil test results should be used to determine if a tree will need a dose of fertilizer. In the absence of soil test results you may observe other signs of low nutrition such as poor tree growth, pale green or yellow leaves, mottled patterns between the veins, stunted leaves or early loss of leaves. Tree vigor also can be determined by checking the growth of several twigs during the past three or four years. Twig/shoot growth on most young trees should be nine to 12 inches or more per year. Large, mature tree twigs may grow only four to six inches per year. Since trees have their greatest need for nutrients in the spring, deciduous trees such as maples and oaks should be fertilized anytime between leaf drop in fall and leafing out in spring, except when soils

are frozen. Evergreen trees, however, such as pines and junipers should be fertilized in the spring. In either case, fertilizer application is not recommended after July. Beyond that time, new growth stimulated by the fertilizer may not have sufficient time to harden off before winter. Newly planted trees should be fertilized only lightly until they have become well established. This usually is not until after their first growing season. Young rapidly growing trees should be fertilized annually to promote rapid establishment. Mature trees may need fertilization every two or three years to maintain good foliage color and hardiness. Tree growth is limited more often by a deficiency of nitrogen than by a lack of any other element.

Deciduous trees such as maples and oaks should be fertilized anytime between leaf drop in fall and leafing out in spring, except when soils are frozen. The standard recommendation is two to four pounds of nitrogen (N) per 1000 square feet per year. For an example, which is equivalent to six to 12 pounds of nitrogen fertilizer Ammonium Nitrate (33-0-0) per 1000 square feet per year. Fertilizer should be spread throughout the area occupied by root system (root zone), which extends four to six feet beyond the branch spread of the tree. The fertilizer can be applied on the soil surface. This method is more efficient for nitrogen fertilizers. If there is a need for phosphorus or

potassium it can be applied below the soil surface via augured holes six to 12 inches deep and spread about two feet apart in concentric circles around the tree trunk.

Gardeners Connect presents

‘Jewels of the Plains’ Revived


ome learn about native plants of the Great Plains and listen to the story of a South Dakota cattle rancher who attained international acclaim as an eminent plantsman of the plains during a free program at 10:30 a.m. on Saturday, Feb. 18. Jim Locklear, conservation director of Lauritzen Gardens, Omaha’s Botanical Center, will present a program titled “Jewels of the Plains Revived.” The program is scheduled for 10:30 a.m. Saturday, Feb. 18, in the auditorium of the Discovery Center, 4750 Troost. The free program, open to everyone, is presented by Gardeners Connect. Coffee and refreshments are planned to be presented before the program at 10 a.m. in the Lewis and Clark Room down the west hall from the lobby and auditorium entrance. “Jewels of the Plains” is the title of a book written by Claude A. Barr that was published posthumously. Locklear has updated the plant names for the classic book. Long out of print, the book is now available again and is a great reference for native plants of the plains.

This talk includes information about native plants but also much more, says Jan Riggenbach, a garden journalist who has presented programs for Gardeners Connect herself. “Jim’s program was both informative and entertaining. It would appeal to anyone who likes native plants and to those interested in unusual rock garden plants, as well as to those who just like to be entertained. I was inspired by hearing more about Claude Barr’s unusual life and his success under very difficult circumstances,” Jan says. “Jim is an excellent speaker.” Through his Prairie Gem Ranch, Barr supplied Great Plains seeds, plants, and information to the scientific and gardening world for many years. His achievements inspired formation of the Great Plains Native Plant Society in 1984. Locklear has been director of conservation at Lauritzen Gardens since 2010. He has conducted conservation assessments of imperiled plants in the Great Plains for the U.S. Fish and Wildlife Service, The Nature Conservancy, the Colorado Natural Areas Program,

and the Nebraska Game and Parks Commission. Among Locklear’s published works is the 2011 Timber Press book “Phlox: A Natural History and Gardeners Guide.” Locklear is the former director of the Dyck Arboretum of the Plains, a 13-acre botanical garden at Hesston College in Hesston, Kan., and the Nebraska Statewide Arboretum, Lincoln.

The mission of Gardeners Connect, founded in 1958 and based at Loose Park, is to “educate and inspire members of the community to become more complete gardeners.” More information on its events can be found at www.

Winter Mower Maintenance To keep a mower in good shape, a little maintenance goes a long way. THERESA PLATT gives us a to-do list.


hen the mowing season ended a few months back, did you take care of your mower before putting it away for the season? If not, there’s plenty of winter left to get that job done. Here are a few tips to assist this important task: 1. Clean your mower – Brush or hose off grass and debris from your mower. Clean the underbody by gently tipping mower on its side, air filter side up and spraying it with a garden hose, or if your

mower is equipped with a wash-out port on the deck, simply screw your garden hose into the wash-out port, turn your mower on and engage the blades. 2. Use a fuel stabilizer – We recommend you fill your tank up with fresh, non-ethanol gas and add a good fuel stabilizer such as Startron, Briggs & Stratton fuel treatment or Stabil 360. Stabilizer will keep fuel fresh up to six months. Run your mower or small equipment for five minutes or so to

allow the gas and stabilizer to circulate into carburetor. Turn off the engine and fill the tank completely full. A full tank will help prevent moisture from condensing in the tank which can form rust or debris that could break away and clog the carburetor. 3. Rider batteries – It is a good idea to remove the battery and store in a cool, dry place, but not necessary. However, if you choose to leave the battery in your rider, go out and start it once a

month or so to keep the battery charged. 4. Store your equipment in the shed or garage, away from the furnace, a water heater or appliance with a pilot light. Theresa and Jim Platt own and operate Northland Feed of Kansas City, Mo., where their team of professionals can answer questions about mower service and repair. You may reach them at 816-4528393.

Ken O’Dell, Kansas City Regional Leader of The Kansas Native Plant Society, will give a one-hour presentation on Wildflowers of the Flint Hills. If you are not familiar with the Flint Hills, it is an area of transition where about 25% of the native species that occur in Kansas reach their eastern or western limits. The Flint Hills of Kansas stretch from near the Nebraska border on the north to Oklahoma in the south. There are no defined borders, but this area is about 40 to 70 miles wide and 200 miles long. The Flint Hills gets it name from the cherty rocks which makes it difficult to properly break up the soil with plows.

Most caterpillar food plants and many pollinator blooms are natives that may challenge a fastidious gardener. Fear of a weedy mess and/ or the reaction of their Homeowners’ Association often prevents gardeners from planting for butterflies and bees. However, my garden contains the host plants for over 50 species of butterflies and there are no “weeds”. Using butterfly host plants as examples, this presentation will discuss the elements of garden design and provide multiple specific tactics to civilize any overly enthusiastic plants. Lenora Larson is a Marais des Cygnes Extension Master Gardener and member of local chapters of both the Idalia Butterfly Society and Kansas Native Plant Society. Questions?

Professional’s Corner

Jeremy Christiansen

What I do in a nutshell: As Plant Health Care Dept. Manager, my responsibilities lie in helping the company grow by hiring people with the right talents and enthusiasm for success on the job. Also, I train and coach team members in developing skills such as customer

of Ryan Lawn and Tree

service, proper spray technique, disease and insect diagnoses, and sales strategies. Education and experience: I graduated from Iowa State University with a B.S. in Forestry, and since have gained 15 years of experience in the industry. What’s the favorite part of your job: Training and leading team members. Best advice for homeowners: Invest in your landscape and you will see huge returns. Adding mulch rings, injecting that Ash tree in the front, planting the hedge row of Arborvitae, and pruning the limbs that are touching the house are all examples of putting money back into our landscape. Whether it is saving on watering costs, heating and cooling bills, or just preventing damage, they all add up. Common planting mistakes: Too often we see trees and shrubs that have been planted too deep. There is a proper technique for planting trees and shrubs which creates the best conditions for healthy, prolific plants. Favorite tree: This is easy. It’s the magnificent Bur Oak. I grew up in Iowa where the expansive landscape is uninterrupted so to fully appreciate this mighty tree. I remember being

awestruck when seeing a Bur Oak standing alone in the middle of a pasture or crop field. It’s such a symbol of strength! Favorite garden destination: To be honest, my garden is my favorite. I love seeing and eating the fruits of my labor! What every gardener should know: It’s important to know what species of trees and shrubs do well where and why ... for success, always research before you buy. In order to have a landscape to be proud of, we must plant the right plant in the right place. Other interests: I’m a huge sports fan: college football, Iowa State basketball, the Kansas City Royals, and of course the Chiefs! Hunting and fishing are activities that keep me outdoors in every season. This is a great pastime to share with my dad and brother, as well as my children. Little known secret: Competition between trees and turf is a huge issue, and mulching is key!
