- 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.

There is considerable spread between above frost, when you say houseplants can go outside, and temps at which these tropicals will thrive. I say they should first go outside in shade during day to acclimate to light and sun, but brought in at night, then when nights are at least 55, not 30s, they can remain outside. There is more to lose than gain to rush the process just as there is with veg transplants,
OOPS, meant wind and sun.
