Re: Cavendish cold hardiness temperature
If it is going to rain, and it has already frosted, you are done. It dies.
If you do frost/freeze, you must bring the temps up immediately (bring it in) and it will recover fine. This has been my experience with cavendish specimens
Average January Low: 40°F, Average August High: 95°F
Typical Low Each Winter: 28-30°F, Typical High Each Summer: 108-110°F, Annual Precipitation: 22 inches
