As leaves emerge on trees and shrubs, check for aphids,spider mites, etc. and spray with Ortho Isotox or Orthene if needed.
Azaleas, Pyracantha, Rhododendron, and Pieris must be sprayed to combat lacebug. Isotox is best - spray 3-4 times, 1 week apart.
Fertilize bulbs again as they bloom. They are heavy feeders and another application will ensure nice blooms next year.
You can start planting hardier annuals near the end of the month. Apply a bloom starter fertilizer as you plant.

It is planting time for trees, shrubs, roses, strawberries and perennials. Get them while they are hot!

Deadhead larger bulbs such as Tulips, Narcissus, and Hyacinths. Be sure not to cut foliage.
