Trees and Shrubs
Flowers
- Bagworms hatch in May. They feed on and defoliate conifers. Treat plants if they were infested last year.
- Shear formal hedges.
- If needed, prune spring blooming shrubs like azaleas, camellias, Indian hawthorn, and oakleaf hydrangea after they finish flowering but before mid July.
- Keep an eye on dogwoods, deciduous magnolias (tulip trees), crape myrtle, and viburnum for powdery mildew.
Flowers
- Let leaves of spring flowering bulbs die back naturally, so they can manufacture enough food for next year’s blooms.
- Replace winter flowers (pansies, snapdragons, etc.) with heat loving annuals like coleus, sweet potato vine, vinca, and scaevola.
