|This is the coldest winter on record (around 20-30 degrees) here in the S. California desert and many Laurels are dying from frost. I would like to protect my Laurels at home, but don't know whether to cover them or just take my chances? I have already stopped watering them.
|Covering your laurels will only help protect them from mild frost - a few hours of 32F. Colder temperatures or temperatures just at freezing for 4 or more hours will require more substantial frost protection; something that's difficult to do for large shrubs and small trees. I'd just leave the plants alone. Whatever frost damage they endure can be pruned away next month. Laurels grow fast and will regrow anything damaged during this unusually cold winter.
Best wishes with your landscape!
