Re: What is the coolest temperature before plant damage?
What is damage? Fried leaves? Dead pseudostem? or just loss of vigor that is never recovered from, tat leads to less fruit or smaller fruit? If the latter, for many varieties, esp. in the Cavendish family, probably 50F. It also matters how long it is cold, and if it is also wet (raining). Cold and wet (above freezing) is more damaging than cold or wet by themselves. A couple nights at 38F is different than two weeks at 45F, but possibly not a damaging. Soil temp probably makes a difference, as well.
