Frosty nights are just around the corner so now is the time to get prepared to protect your frost sensitive plants. In San Luis Obispo, the first average frost date is right around Thanksgiving. Understanding how to protect your plants can save them from damage and even death.On clear, windless nights when temperatures dip below 45 degrees at 10 p.m., it may be a signal to protect your plants before going to bed. Move any tender container plants under a porch roof or into the garage. Cover plants in the ground using burlap, sheets, blankets or specially designed Frost Protection Blanket. If possible, support the covering material so it isn't in direct contact with the plant. Freezing may occur where foliage touches the covering material. Remember to remove the covering during the day. Continue to water your plants as needed during the winter. Properly hydrated plants fair better during frosts than dry plants.
If plants have suffered damage from frost, it's best to wait to prune. Pruning too soon will stimulate new growth that can suffer damage from later frosts. Also, the already damaged areas still serve as protection for the undergrowth. It's best to wait until new growth begins to show in spring to determine what is clearly dead.
Continue to water your garden as you normally would during the winter but don't over water. Increasing the watering will not help your plants recover any quicker from frost. And don't feed your plants until new growth begins in the spring.
