Plants need to be covered during the frost

Question

I have quite a few succulents and cactus in the high desert do they need to be covered during a frost

Answer 1

Many succulents can survive a couple of freezing nights. But taking extra precautions can include placing them in a protected area, such as in a greenhouse or garage, or covering them temporarily with fabric or landscape cloth or even an upside-down pot. If you have a deck or eaves where they might get some protection, it would help. Also, make sure they are planted in super well-draining soil, and that they are getting plenty of air circulation and light. This article may be helpful:
