Can peppers survive 40 degree weather?
To sum it up, most peppers won’t necessarily DIE from 40 ̊ F temperatures , but their growth can be stunted, and they may be slow to recover so it’s best to keep them warm if possible.
What temperatures can jalapenos tolerate?
Jalapenos thrive in warm conditions and need temperatures between 65 and 80 F. (18-27 C.) to germinate. Temperature is critical, and unless it’s warm enough, pepper seeds won’t sprout and transplants won’t survive.
Can jalapenos handle cold weather?
Like all hot peppers, jalapenos are intolerant of frost . Mature plants with ripening fruit may be destroyed if they get hit by frost.

Although mature plants might survive light frosts, temperatures below 40 F damage flower and fruit production, making tomatoes perennial only in U.S. Department of Agriculture zones 12 and up. ... Above 95 F, the flowers abort and will not produce fruit.
What’s the lowest temperature pepper plants can tolerate?
Pepper Plant Temperature Tolerance
Seeds need a soil temperature between 70 and 95 degrees Fahrenheit for best germination and won’t germinate at all, according to Cornell University, at temperatures below 55 F. Once they’re growing, plants can be kept where the air temperature is 70 F during the day and 65 F at night.
Will Peppers germinate at 60 degrees?

What temperature is too cold for eggplant?
Eggplant is generally more sensitive to cooler temperatures than its cousins, tomatoes and peppers. Flowers consistently set fruit down to 60 F nighttime temperatures. Eggplants begin to get chilling injury at temperatures below 50 F. Staking may be necessary if plants get big and full of fruit.
Is lettuce a frost tolerant?
Lettuce is tolerant of cold temperatures for short periods of time, although growth will slow down. To protect lettuce in frost prone areas, plant romaine or butterhead lettuce, which are the most cold-tolerant. When frost is predicted, cover the garden with sheets or towels to provide some protection.
