(WMC-TV) - Cold temperatures and frost can damage your plants very quickly.
Here are a few tips to keeping your plants safe through a freeze as provided by University of California:
- Water the soil thoroughly (except around succulents). Wet soil holds heat better than dry soil, protecting roots and warming air near the soil.
- Bed sheets, drop cloths, blankets and plastic sheets make suitable covers for vulnerable plants. Use stakes to keep material, especially plastic, from touching foliage.
- Remove the coverings when temperatures rise the next day.
- For a short cold period, low plantings can be covered with mulch, such as straw or leaf mold. Remove once the danger of frost has passed.
- Place a 100-watt lamp designed for outdoor use in the interior of a small tree. It can emit enough warmth to reduce frost damage. Holiday lights (not the LED type) serve a similar function, but be sure they don't touch any covering materials.
- Spray an anti-transpirant, available at your local nursery, on the foliage of cold-sensitive plants to seal in moisture. One application can protect up to three months by coating the leaves with an invisible polymer film.
- Cluster container plants close together and, if possible, in a sheltered spot close to the house.
