Frost Damage

Question

I live in Redding, CA. When temps went to 16 degrees, all of our Gardenias burned. Should I cut them back or just replace the plants (about 8 plants once 36 inches tall. )?

Answer 1

The leaves will regrow as long as the stems are still alive, but it will take some time. Whether you keep them or replace them really depends on how soon you want the plants to look nice again. These articles will help you:
