1. Spraying foliage regularly with liquid seaweed (2 tbls/gallon of water) raises the sugar content of the sap over time, making plants more resistant to freeze damage.
2 . Water thoroughly before a forecast freeze. This hydrates the plants and reduces the likelihood of killing damage. Sprinklers must be turned off while the temperature is actually below freezing because water sprayed on frozen foliage produces devastating results.
3. Apply 2” to 4” of compost or living mulch over the lower stems and root systems of tropical, tender shrubs, and perennials. This ensures that even if the tops freeze, the plants will most likely regrow in the spring.
4. Have sufficient N-Sulate or Plant Jackets on hand to cover your plants. These fabrics offer protection from frost, several degrees insulation from the cold, and reduce the dehydrating effects of cold winds.
