What to do in your garden in June

PLANTING AND SHOPPING

Annuals. Set out transplants of bedding begonia, coleus, cosmos, impatiens, Madagascar periwinkle, marigold, pelargonium, petunia, portulaca, mealycup and scarlet sage, sunflower, sweet alyssum, and zinnia.

Bulbs and tubers. In the sun, plant agapanthus, calla, canna, crocosmia, dahlia, gladiolus, and tigridia. In the shade, plant Japanese anemone and tuberous begonia.

Color for colder climates. Even after an early freeze hit Georgeson Botanical Garden in Fairbanks, Alaska, observers there reported that the following plants kept right on blooming: Agastache, black-eyed Susan, calendula, chrysanthemum, English daisy, gazania, Geranium, godetia, linaria, lupine, pansy, petunia, salvia, snapdragon, statice, stock, strawflower, sweet alyssum, tidy tips, verbena, and viola. Visit www.uaf.edu/snras/gbg for names of specific varieties of the plants above.

Lawns. Sunset climate zones A1­A3: Sow seeds or lay sod now so turf will have time to become established over summer. Zones 1a­7: Before starting a new lawn from seed or sod, be sure you'll be able to apply 1 inch of water per week from now through autumn.

Perennials. Set out all kinds from containers this month. Summer and fall bloomers include aster, black-eyed Susan, blanket flower, coreopsis, feverfew, penstemon, perennial sweet pea, potentilla, purple coneflower, and salvia.

Shop the big show in B.C. VanDusen Botanical Garden in Vancouver, B.C., hosts a garden show outdoors, with more than a dozen theme gardens and 250 exhibitors. Inspectors will be on hand to issue permits that U.S. visitors need in order to bring plants across the border. 10-6 Jun 10-13; about $10 U.S. 5251 Oak St.; 604/878-9274.

Vegetables. Sow beets, bush beans, carrots, lettuce, onions, peas, radishes, spinach, Swiss chard, and turnips. Set out seedlings of cucumbers, eggplant, peppers, squash, and tomatoes.

MAINTENANCE

Care for apples. After trees naturally drop some of their fruit in June, they may still need more thinning. If the crop is heavy, thin triple clusters to doubles, and doubles to singles. To control apple maggot worms, hang red sticky traps in the trees (red balls coated with a sticky substance like Tangle-Trap Insect Trap Coating, for example).

Water wisely. Lawns need 1 inch of water per week during summer to keep from turning brown. Where water is in short supply, apply 1/2 inch per week and let the grass go semidormant.
