Protecting your plants as temperatures drop overnight

Posted: Updated:

SAN DIEGO (CBS 8) – A frost advisory is in effect for San Diego County valley and coastal areas until Saturday morning.

Yard specialist say all it takes is one frost for your plants to burn.

"You want to protect them you don't want to have burned leaves for the new year,” said Richard Wright, Home Orchard Specialist for Edible Eden.

The burn could happen during the frost advisory issued by the National Weather Service who forecast temperatures to drop in the 20's in some areas.

“Hibiscus is a wonderful plant here in San Diego under our normal weather conditions but when it comes to frost they will burn like tissue paper,” said Wright.

Wright demonstrated for CBS News 8 how to drape a blanket, tarp or sheet over your plants with a pole or stick to make a tent. He recommends you avoid putting the material directly on the plants so the cold won't transfer, "It's a tent above the plant not on it but above it,” said Wright.

During this fronts farmers are also watching their crops.

“A grower that is growing something tender say lettuce or strawberries that is seasonal, those plants are a little bit tender so we have to be careful for those,” said Eric Larson, San Diego County Farm Bureau Executive Director.

Strawberries are crucial to keep an eye on right now. Strawberry farmers in San Diego County pick their crop in January to sell before the competition in Ventura County and Salinas Valley.

The frost isn't expected to be severe this weekend but in January 2008 cold weather damaged crops in San Diego County causing farmers to lose trees and damage fruits.

“It's not so much how cold it gets but does it stay cold for a long period of time,” said Larson.

The yard doctor also recommends you avoid pruning during the frost season that way new growth won't burn.

A frost advisory is in effect for Friday and Saturday nights into Saturday and Sunday mornings.
