Q: The last time we had a frost, I covered my plants with plastic and they froze anyway. Should I have used something else?
A: Yes. One of the biggest mistakes homeowners make is covering their plants with plastic during a freeze. Plastic conducts cold, so unfortunately, your plants were damaged even more than not having been covered at all. Instead, purchase frost cloth at any major hardware store, or use old sheets to cover your plants. Both of these materials are lightweight and able to breathe, plus they’re a much better choice than heavy tarps that can crush your plants.
Also be sure to remove your frost cloths and sheets first thing in the morning after an overnight cold snap. If you don’t, condensation can build up and freeze again under the covering.
