Gardening Tips for May

- Set out traps for earwigs, slugs, and whitefly.
- Thin pit fruits at or before pit hardening.
- Thin apples when ½” diameter.
- Mow grass or cultivate soil around orchard to discourage thrips and plant bugs.
- Mulch around plants to control weeds and conserve moisture. Be sure to leave a small circle of bare soil around the base of each plant.
- Deep water trees and shrubs. Build water basins, but do not allow water to stand against the trunks.
- Prepare dahlia bed with rich soil.
- For continued bloom, cut off spent flowers.
- Hang strips of foil or CD’s in fruit trees to help deter birds.
- As spring=flowering shrubs finish blooming, prune to shape, removing old and dead wood.
