When temperatures get close to reaching freezing (32 degrees) many types of vegetation need to be protected. Some of the applications worth considering are:
1. Lay old sheets over frost sensitive plants. This is short term and will trap moisture and heat that radiates from the earth.
2. Weave Christmas tree lights through branches of citrus trees.
3. Row covers consist of fabric over wire to provide tunnels that protects a row of plants. Light, air and water are allowed through while pests are not.
4. Cold frames work like a small greenhouse; they contain heat and moisture and have a transparent material that lets in light.
5. Frost cloth can be placed over the exposed areas of frost sensitive vegetation.
6. Mulching maintains a steady soil temperature, just keep mulch several inches away from touching the plant.
7. If in containers, plants can be moved to a sheltered area. Look for places with overhangs, tree protection, or micro-climates.
