Quick ways to protect your garden plants from frost damage.
1. Drape tender plants, potted plants or fruits and vegetable plants loosely with old sheets and blankets, bulap, towels or large scraps of fabric. Secure with string, twine, rocks, bricks or stones. Heavy covers may need support to prevent crushing the plants. Support these heavy fabrics with stakes or sturdy branches. The next morning early remove all covers to prevent suffocation.
2. Water the soil up to 2 days before the expected frost. Damp soil holds heat better than dry soil will. Generously misiting the plants thoroughly the night before frost, just before the temperature begins to drop, protects your plants from frost damage. The water helps the plant hold in warmth.
3. Lightly cover plants with straw, leaves, pine needles the night before frost and be sure to uncover the next morning. Heavily mulching tightly around the base of the plants will, also, help to keep the plants warm during frost and freeze.
