If your azaleas, rhododendrons, and other spring-flowering shrubs are growing too large, prune them after they bloom.
Thin out interior boxwood branches to improve air circulation and reduce disease problems such as volutella canker. Also, look out for boxwood blight.
Move houseplants outdoors after the danger of frost has passed. To avoid sunscald, first place them in a shady location and over a period of two weeks or so to gradually introduce them to more sunlight.
Pinch the blooms from flower and vegetable transplants before you set them out. This will help direct the plants’ energies to root development and will result in more productive plants. Gently break up the roots of root-bound transplants before planting.
