All about frost protection

A few notes about frost protection from our friends at Redwood Barn Nursery in Davis.

How can I protect plants from frost?
Protecting plants from frost damage usually is accomplished by trapping the heat that is radiating from the ground with clear plastic or similar materials, by moving the plant to a sheltered location, or by directly providing heat via light bulbs. Additionally, anti-transpirant sprays — Cloud Cover is one brand — will provide a couple of degrees of protection if applied at least a few hours before you expect frost. Each measure gives about two to three degrees of protection, so try them all on a tender plant you value. Keeping plants well-watered is important in freezing weather. While we’ve had enough rainfall for plants in the ground, container plants are especially vulnerable to the desiccating effects of freezing.

Which plants are likely to be damaged?
Plants always killed by frost include your summer annual flowers and vegetables: Impatiens, Coleus, marigolds, tomatoes and peppers. There’s no point in trying to protect these; simply replace them next spring.

Any house plants that have been growing outdoors need to be brought inside–by Hallowe’en as a good rule of thumb. Check them first for aphids, ants, or other pests; to make sure you don’t include any uninvited guests. A quick spray with a soap solution can prevent unpleasant surprises!
