Northwest: May Garden To-Do List | Regional Report

Cut back. Give the “Chelsea Chop” to suitable perennials that you want to keep lower or delay bloom for until late summer. Good candidates include phlox, asters, heleniums, and solidagos. If flopping is a concern, add supports that will disappear with new growth.

Keep up with the roses. Deadhead early blooming and repeat blooming roses for continuous blossoms.

Care for your bulbs. Lift and divide larger clumps of spring bulbs. Remove their spent flowers, but leave the foliage to help regenerate or strengthen the bulbs.

Be ready with the pruners. Watch deciduous shrubs and trees, and make minor adjustments to pruning as necessary.

Prep for later. Plant late-summer annuals.
