Gardening Calendar
|  |
This calendar is provided as a general guide to gardening activities.
May
- Pinch azaleas and rhododendron blossoms as they fade. Double-flowered azaleas need no pinching.
- If spring rains have been sparse, begin irrigating, especially plants growing in full sun.
- Apples, crabapples, and hawthorns susceptible to rust disease should have protective fungicidal sprays applied beginning when these trees bloom.
- Slugs will hide during the daytime beneath a board placed over damp ground. Check each morning and destroy any slugs that have gathered on the underside of the board.
- Growing lettuce under screening materials will slow bolting and extend harvests into hot weather.
- Place cutworm collars around young transplants. Collars are easily made from cardboard strips.
- Keep bluegrass cut at 1.5 to 2.5 inch height.
- Mow tall fescues at 2 to 3.5 inch height.
- Watch for sod webworms emerging during last week of month.
