Protect plants from late freezes. April 29 is the average date for the Rogue Valley's last frost.
Harden off seedlings before planting in the garden. After spending their infancy in protected greenhouses, even frost-tolerant perennials and annuals need to be acclimated. Place them outside for increasing periods each day and protect them in a sheltered area at night. After seven to 10 days, they are ready to go into the garden.
Prune early flowering shrubs, like camellias, after flowering ends. Small trees to prune this month include crape Myrtle, mugho pine, witch hazel and pussy willow. In general you should never remove more than one third of any plant you prune.
As we like to remind you, don't remove bulb leaves until they yellow. Depending on sun requirements, plant annuals such as peonies, 'Autumn Joy' sedum, lady's mantle, hosta or plant the taller Joe Pye weed (Eupatorium purpureum) around the bulbs to keep it lovely. To keep bulbs healthy make sure whatever you plant has minimal water requirements.
When purchasing perennials, try to buy them before they bloom, unless you simply must see the flower color. Check for compact growth, healthy foliage color, and a vigorous root system. Roots should not be growing out of the bottom of the pot, and should be white, not brown.
