May Garden To-Do ListHere is our comprehensive garden task list for gardens in the greater DC metro region for May 16-June 15. Your additions to this list are most welcome:If you started seeds last month, thin them and start the hardening off process. • Cut back spent tulip and daffodil blooms, but not the foliage! • Divide and replant crowded daffodils. • Feed your roses and new plantings with slow-release fertilizer sparingly. • Provide supports for fast-growing perennials such as delphiniums, peonies, and lilies. • Tie up clematis and other fast-growing climbing vines. • Hose off aphids, white flies, or spider mites on your roses or other perennials. • Deadhead spent blooms on your annuals and perennials to encourage re-flowering. • Water your newly planted shrubs, trees, and perennials. • Weed regularly. • Go on a local house and garden tour to see what plants are thriving in other’s area home gardens. • Pinch back mums, salvias, and other late season bloomers to encourage bushy not leggy growth. • Check pots and containers daily for water needs. • Plant dahlias, gladioli, caladiums, and cannas. • Direct sow annual flower seeds. • Thin vegetable seeds sown directly in the garden. • Move your houseplants outdoors for a summer vacation on your porch. • Put out slug traps around your vulnerable edibles and hostas. • Prune back forsythia, spirea, and other early spring blooming shrubs. • Check for black spot on your roses -- remove and discard and affected leaves in the trash, never back into your garden or in your compost -- apply a fungicide with neem oil every two weeks during the growing season. • Cut some flowers to enjoy inside -- make a small arrangement for every room. • Sow squash and melon seeds. • Plant seedlings (or direct-sow) sweet potatoes, tomatoes, peppers, and eggplants. • Fertilize azaleas and rhodos, if needed. • Divide crowded perennials and share them. • Turn your compost pile. • Start a water garden or re-new yours for the season. • Mark and photograph your bulb plantings now, while they are still visible. • Keep a sharp eye for fungal diseases and pests. • Replace cool-season annuals with heat-loving ones. • Be vigilant for mosquito breeding spots, any standing water from a bottle-cap to blocked gutters, and clean them out immediately. Ask your surrounding neighbors to do the same. Put Mosquito Dunks or Bits in any areas that accumulate water.• Plant tomatoes and peppers. To get them started off right, put cages/stakes in at same time as you plant them, so that you are not disturbing their roots later. Place a collar (cardboard tube or cat food can) around the tender plants to prevent cut worms. Put crushed eggshells first in the planting hole of tomatoes for extra calcium and mix lime in the soil you surround the plant with to prevent blossom- end rot. Fertilizes with kelp extract or fish emulsion.• Hand pick cabbage worms from cabbage and broccoli.

Container Gardens Made EasyMany people walk into a garden center with glorious plans for a container garden, only to be completely overwhelmed by rows and rows of plants. So they buy a bunch of varieties they like and cram them in a pot, only to be discouraged when those selections die, grow out of proportion or end up sporting color combos that just don’t work.That’s why Tesselaar Plants, in its goal of “Making Gardening Easy,” offers these 10 tips and plant-by number recipes from container design pros Barbara Wise and Todd Holloway. Holloway is the owner of Pot Incorporated, an award-winning contain-er and landscaping company in Vancouver, BC. Wise is the author of the new book Container Gardening For All Seasons (Cool Springs Press, $21.99).

1. “ECHO” COLORS“I like to echo colors,” says Wise. This means looking for hues in one plant that can be reflected in another plant used in the same container. For example, she likes pairing Strobilanthes ‘Persian Shield’ with Torenia ‘Golden Moon’ because the purple throat of the torenia echoes the purple of the strobilanthes.2. CONTRAST TEXTURESWise and Holloway both recommend mixing different tex-tures. Fine or delicate foliage contrasts nicely with straight, narrow stalks and broad tropical leaves. Similarly, long, skinny, linear leaves or strappy, arch-type formations look great when paired with full, rounded or oval shapes. “I focus on the foliage contrast with one or two complemen-tary flower varieties,” says Holloway.3. CHOOSE PROVEN, EASY-CARE PLANTSEspecially if your pots can’t be placed close to your water source and you’re limited on time, says Wise, choose plants that aren’t as needy. Succulents, of course, require little care, but the same can be said for tropical plants like mandevilla, cannas like the colorful Tropicanna line and cordylines like Festival Burgundy™. Even roses can be used in con-tainers, says Wise, if they’re disease-resistant and drought- and heat-tolerant. “Flower Carpet® roses, for instance, look fabu-lous trailing over the sides of containers.”4. DON’T FORGET THE POT!Some plants, like Tropicanna cannas, will grow up to 6 feet high by the end of the season and enlarge their root size so much, they break through the pot. So Wise recommends making sure all the plants you plan to put in the pot will remain in scale and that your pot size is one-half to one-third the size of the tallest plant when mature. In fact, if Holloway had to recommend just one tip for successful containers, it would be to make sure the pot is large enough. “It must have enough volume to accommodate the roots of the plants’ ultimate size,” he explains. At minimum, it must have at least half the volume of the size of the mature plants. “Your planter must be large enough to accommodate the plants throughout their life in the container,” he explains. “At the very least, your container’s volume should be roughly a third to half the size of the eventual volume of the mature plants. If your mature plants are expected to grow to 3 feet tall by 3 feet wide, your plants should be no smaller than 1 to 1.5 feet tall by 1 to 1.5 feet wide.” And remember, the pot’s style, material, color and texture are just as important an element in con-tainer design as the plants themselves, says Holloway.5. THINK “THRILLER-SPILLER-FILLER”This tried-and-true design trick is a great way to make sure your container gardens have the right scale, proportions and mix of shapes and textures. “For your thriller, try a tall or upright focal point plant such as cannas or cordylines,” suggests Wise. “For your filler, you’ll want a plant that’s bushier or fuller, like a daylily or caladium. The spiller, she explains, is any plant that will trail or cascade over the edge of the pot, like petunias or lysimachia (creeping Jenny). “Remember to mix in fine foliage with your big leaves and to add a little repetition or color among the plants. This makes for a more cohesive, unified piece.”6. SAME NEEDS, SAME POT“Know the difference between full sun, partial shade and full shade, and choose plants with like cultural requirements in one pot,” says Holloway. Or, as Wise likes to put it: “Know who your plants’ friends are.” This not only ensures healthy plants, but cuts way down on your maintenance routine. “Keeping light exposure in mind while considering plants is extremely important,” says Holloway. “Knowing whether your plants do best in full sun, part sun, part shade of full shade is a good

starting point once you’ve determined the location of where your planter will live. Always make sure all the plants in the pot are tolerant of the light conditions of your location.”7. CONTAINER CARE 101Plants in containers have different needs than those in the landscape. Here, Wise and Holloway provide a few basics:Plant spacing/placement. Even though Holloway likes cramming in lots of plants, he still encourages planting them a few inches apart to give roots a chance to spread and establish quickly. After filling the container with soil up to a few inches from the top of the pot, he recommends starting your design with large plants and adding smaller ones as you move to the edges of the pot. “Fill with soil as you go, making sure the tops of the roots aren’t covered with more than a half-inch of soil.”Moisture. Because there’s less soil in containers, they tend to dry out quicker than their counterparts in the ground. So Holloway recommends keeping an eye on when your plants need a drink, especially later in the season, when they’ve gotten bigger: “Allowing your planter to fully dry out one or more times causes considerable stress on the plants, often preventing them from fully recovering or reaching their full potential.” Holloway recommends watering with your sprayer on a gentle shower setting. “You can stop watering when water flows freely out of the bottom of the pot,” he says. Wise suggests keeping pots as close as possible to your water source, to cut down on the water hauling. She also recommends using a potting soil made for containers instead of soil dug up from the ground. “The lighter components of potting soil provide more aeration for roots,” she explains. Checking for moisture is easy, she says: “Just stick your finger into the soil, up to your first finger joint. If it feels dry, then water.” On the other hand, you don’t want roots to rot, so make sure there’s a hole at the bottom of the pot for good drainage. Feeding. For easier feeding, Holloway and Wise recommend a slow-release, granular fertilizer. “It doesn’t hurt to apply some liquid fertilizer occasionally as the plants grow larger,” notes Holloway, “especially tightly planted containers, where fertilizer is in high demand.” Keep ‘em in shape. Holloway and Wise recommend keeping plants under control (bushier and with more blooms) by pinching, pruning and deadheading throughout the season.8. THINK OF THE BIGGER PICTURE“The container and the plants must always complement their location,” says Holloway. In her book, Wise devotes a whole chapter to the concept of “contain-er-scaping,” or using container gardens year round as landscaping supplements, garden focal points or décor accents in your “outdoor room.” You can also treat your containers as constantly evolving props, moving them to perhaps cover a hole in the landscape or changing out spent plants as new seasons arrive. “You can create a lush container-scape, maybe even a paved paradise, when you fill it with potted plants,” she says. “The options are endless.”9. ADD SOME ARCHITECTUREJust as a landscape needs good garden “bones” to give it three-dimensional interest and characters, containers can always use a beginning structure or skel-eton. So give it to them, says Wise, with manmade materials, trees and shrubs or architectural plants like agapanthus, cordylines, phormiums or succulents. “A pyramidal trellis in the center of the container, for instance, adds height and can showcase stunning annual vines like mandevilla and passion flower.” A topiary hibiscus is also striking, she adds, especially with a thick grouping of daylilies below. “And I love shrub roses in containers underplanted with Purple Queen setcresia and lantana.10. CHECK OUT THESE OTHER RESOURCESYou’ll find more container gardening inspiration from Wise in her book, Container Gardening For All Seasons, which hit bookshelves last month (April 2012). This at-a-glance recipe book of sorts offers 101 full-color photos of container garden designs for all seasons, climates and personal tastes. Each recipe comes with a shopping list, a coded “plant-a-gram” (showing which plants go where) and a listing of sun preference, pot size and difficulty level. Wise also offers plenty of ideas on her blog, B Wise Gardening. You can also find stunning container designs on Holloway’s Pot Incorporated web site, particularly on the home page’s slideshow or “Gallery.” Pot Incorporated’s Facebook page is routinely updated with inspirational material as well. Also see the two container gardening cover stories in the September/October 2005 and March/April 2008 issues of Washington Gardener Magazine. You can order back issues of the magazine using the lusting on page 8 of this newsletter.

Magazine Excerpt: Brunnera: Bright Star of the Shade Garden by Judith MenshIt shines in the shade, a silvery sheen with green crinkles, a reminder of the winter we haven’t had this year. ‘Jack Frost’ Brunnera macrophylla has won the 2012 horticultural Oscar: the Perennial Plant of the Year Award. Its leaves are gilded with a silver surface, networked with contrasting green veins, and, in spring, a cloud of true-blue flowers arise. Due to unique chemical composition and cell physiology, anthocyanins allow their flowers, like their family members Mertensia virginica and Borage, to be true blue as opposed to horticultural blue (visually purple). Add this winner to your repertoire of fabulous foliage plants — the Heucheras, the Hostas, the Caladiums. Not native to North America, but a well-behaved import (the only one of the three genus of Brunnera in cultivation), it can be grouped or massed: A clump can be an eye-catching focal point, or it can wend its way around a woodland area, creating a border or providing ground cover. A startling chartreuse version glows in the garden border and in large pots. Highly praised as good garden citizens, the Brunneras are recommended as container plants. If you plant Brunnera in a shade container, you have access to immediate flower-arranging material. A member of the Borage family, its common names include Heartleaf, False Forget Me Not, Perennial Forget Me Not, and Siberian Bugloss. First came the variegated variations, with whites and creams, ‘Variegata,’ or ‘Dawson’s White,’ then the silver arrived, with ‘Langtrees’ aka ‘Aluminum Spot.’ ‘Langtrees,’ long a favorite for its silver speckles, has given us ‘Jack Frost’ and, from there, the silver look spread. Remember the elfin Jack Frost from Norse legend, who came through and touched all the world with his magic wand, creating beautiful frost displays everywhere? Brunnera bloom early and stick around to grace the garden with lovely leaves straight on through the winter when, at last, cold temperatures induce it into dormancy... Want to learn more about growing Brunnera? Read the rest of this PlantProfile in the Spring 2012 issue of Washington Gardener Magazine. See the subscription information below.
