The Q&A Archives: Dealing With Freezing Temps

Question: Is there a product on the market that you can spray on to keep plants and things from freezing?

Answer: Experienced commercial growers are currently frost-protecting citrus, avocados and strawberries with anti-transpirant sprays. All the plant surfaces are sprayed prior to anticipated freezes, and the protection afforded is suggested to be from two to eight degrees (?F). Here is a list of some available products:
Wilt-Pruf -- by Wilt-Pruf Produces, P.O. Box 469, Essex, CT 06426.
Frostguard -- by Custom Chemicides, P.O. Box 11216, Fresno, CA 93772. Available from local farm suppliers.
Frost Shield -- by Maz-Zee S.A. International, P.O. Box 82717, San Diego, CA 92138. Available from Peaceful Valley Farm Supply.
Of course not all products are suitable for all plants. Read the directions carefully to make sure your plants are those that will benefit from one of these sprays.
