June Garden To-Do List

Spotlight Special Canna ‘South Pacific Scarlet’ AAS Flower Award Winner

AAS* Judges raved about this first F1 hybrid canna from seed because it is such a floriferous bloomer. ‘South Pacific’ grows up 4-5' tall, providing a great grouping of specimen plants or a back-of-the-border focal point. The colorful blooms are produced on a flower spike held above the large leafed statuesque plants. Home gardeners will love the robust nature and the many flower-laden branches it produces. ‘South Pacific’ boasts 6-7 stems per plant and delivers larger flowers than other seed cannas. The scarlet flowers appear early, bloom consistently all summer and withstand a light frost better than comparisons. As with other cannas, ‘South Pacific’ tolerates wet conditions, so it can be used as a pond border or in other similar growing conditions. Canna is a perennial, but can be treated as an annual by Zone 6 gardeners. Rhizomes can be dug before first frost and stored properly for the next season. Bred by Takii & Co. Ltd.


Genus species: Canna generalis Plant type: Tender perennial in zones 7-10 Garden location: Full sun Garden spacing: 18-24 inches Length of time from sowing seed to flower: 11-12 weeks *AAS or All-America Selections is a nonprofit organization founded in 1932 to test new flowers and vegetables for home gardening. We utilize a network of over 40 trials grounds across North America 2

Here is our comprehensive garden task list for gardens in the greater DC metro region for June 16-July 15. Your additions to this list are most welcome: • Direct sow annual flower and vegetable seeds. • Water newly planted trees and shrubs weekly or as needed. • Contact a certified arborist to have your trees’ health inspected. • Check on your container plants daily and keep them well watered. • Watch for insect and disease problems throughout your garden. • Mow in the early evening and cut off no more than one-third of the grass height at one time. Leave grass clippings on the ground to provide nutrients. • Add barley straw (in a bale or ball) to your pond to improve water clarity. • Take cuttings from azaleas and roses to start new plants. • Harvest herbs to use in salads and summer dishes. • Try a few new tropical plants on your patio. • Shape your evergreens and hedges. • Look for slug trails in the early morning and put out slug bait as needed. • Tie-up climbing roses and other wandering vines. • Fill in bare spots in the garden with annuals. • Deadhead spent flowers to encourage reblooming. • Prune flowering shrubs as their flowers fade. Last chance to do so for fall blooming camellias. • Spray roses with Neem oil every two weeks. • Start a sunflower patch with help from a few kids. • Harvest strawberry beds daily. • Cut a few flowers to enjoy at your workplace. • This is the perfect time to apply grub control. • Change the water in your birdbath daily and throw a mosquito dunk (or bits) into any standing water. • Put in supports for tomatoes and tall-blooming plants such as dahlias. • Order spring flowering bulbs to arrive for planting this fall. • Take photos and update your garden journal. • Inspect your garden hose for leaks and tighten all connections. • Weed. • Sow beets, beans, cucumbers, pumpkins, and squash for fall harvest. • Prune boxwoods. • Sharpen your lawnmower blade. • Avoid pesticides or any chemicals near your water garden. • Make hummingbird food by boiling two cups sugar in four cups water. • Turn your compost pile. • Clean up fallen fruit and berries. • Cover berry bushes and fruit trees with bird netting. • Dig up garlic when the tops turn brown. Let dry in the sun then braid and store. • Fertilize your azaleas and rhododendrons and monitor them closely for any lacebug damage. • Sow heat-tolerant greens like Swiss Chard and mustard greens in part-shade. • As the heat and humidity move in, take it easy by working in the morning or early evening to avoid intense sun and humidity. Leave the big projects for this fall. For now concentrate on maintaining the beds you’ve already established and nurturing your new plantings.

Pet-Friendly Gardening

Cats and Dogs Can Coexist with Your Gardens By Kathy Jentz

If you love your canine and feline family members and your outdoor spaces, here are a few ways they can co-exist in harmony with each other. Pets and gardens go together well, like, wool and seersucker – meaning, not really a natural match, but you can make it work with a little designing, flair, and planning. The most important thing is to ensure your plantings are pet-friendly. The ASPCA has a comprehensive list of poisonous plants to avoid in your garden at Common toxic garden plants to avoid are Asiatic Lilies, Lily of the Valley, Yews, and Foxgloves. Next, you will want to put in plants that can put up with some animal foot traffic and even an occasional napping. Try Ornamental Grasses, Clumping Bamboos, and Ferns. Cover bare ground with sturdy groundcovers like Ajuga, Liriope, and Alyssum. Add color with edible flowers like marigolds, snapdragons, and thornless roses. If your “fur baby” is like many pets that love to chew and eat anything they can get in their mouths, you will want to avoid using tools and garden materials that are toxic to animals. Top of the list is to avoid Cocoa Mulch. Keep pets away from slug and rodent baits as well as soil amendments like bone meal and blood meal. Fertilizers can also be dangerous for pets to ingest. Be sure to store your garden tools and hoses after each use so that your dog does not “discover” them and make them his new chew toys. 4

As we reported in the Spring 2012 issue of Washington Gardener Magazine, “High amounts of lead, phthalates, and the toxic chemical BPA were all found in the water of a new hose after it sat outside in the sun for just a few days.” We recommended you choose polyurethane or natural rubber water hoses, and non-PVC tools and work gloves. Tools can also cause injury when pets step on them or rub against them, so store all un-used pruners, hoes, etc. in a safe place. The compost pile can be very tempting to pets, but coffee grounds and moldy foods can be toxic to them. Keep your compost contained and offlimits to pets or bury it. Avoid using any pesticides or herbicides around areas pets will visit in your garden. There is no long-term testing for pet “safe level” exposure to these lethal chemicals. Your pets are, of course, current on their rabies vaccine, right? It is still a good idea even so to keep an eye on your pet anytime they are outdoors to make sure they do not accidentally encounter a rabid animal or play with a dead carcass. Fleas and ticks are a concern for all pets. Keep your lawn neatly trimmed as ticks love tall,

unkempt grasses, Check your animals regularly with a flea comb and for any tick hitch-hikers.

Specific Tips for Cat Owners Most of the advice for cats in gardens centers on their skills as a master predator. This is fantastic for those of us with mole, vole, or other rodent issues. However, we do want to watch out for the other beneficial animals that visit our gardens like birds. Put a bell on your cat’s collar and keep bird feeders high and away from where cats can jump to them. Provide birds with safe shelter like a prickly holly bush that they can retreat to.

Specific Tips for Dog Owners The best thing to do is to set aside a space where your dog can dig and do as he pleases. Otherwise, you are chasing him all over your yard yelling “No!” and the poor thing starts to think that is his name. Give him a shady spot in a outof-the-way corner where not much grows anyway. Mark it off with a stone or wood border and every time he digs where he is not supposed to, bring him over to his “yes” spot. You might even add a few bags of sand to the area to make it more fun for him to dig in. With just a few precautions you and your pet can enjoy your gardens stress- and hazard-free.

Magazine Excerpt: Have Your Squash and Eat It, Too!

BY ELIZABETH OLSON Gardeners who like to grow squash have to cope with one of the most vexing indigenous pests: the squash vine borer, Melittia cucurbitae. A single borer larva can cause significant damage to — or the death of — a squash vine. The borer afflicts cultivars of the squash species Cucurbita maxima and C. pepo. The majority of familiar summer squash, winter squash, and pumpkin cultivars belong to these two species. Common practices to ensure a crop from susceptible cultivars include: • Preventive pesticide applications • Surgical removal of borers from infested vines • Trying to outpace borers by encouraging the formation of roots at the leaf nodes of running vines that sprawl on the ground • For bush-type summer squash, expecting borer damage and a limited crop, then destroy infested plants before the growing season is over. The easiest and most productive option is to plant cultivars of squash species that are naturally resistant to the squash vine borer. This works very well, especially in gardens such as the traditional Three Sisters garden, where access to squash vines is problematic during the growing season. Naturally resistant squash species are C. moschata and C. argyrosperma (syn. C. mixta). These two species have a surprising number of cultivars, are well-adapted for the greater Washington region, and have the same general cultural needs as the better-known squash species. The plants have running vines that can be managed; see the recommendations in Cultural Notes on page 14 of this issue... Want to learn more about growing Squash and fighting the vine borer?
