I put the last of my peppers out the day before yesterday, in five gallon grow bags out front. Before they went out, I did about a week of hardening, which involves taking them outside for a few increasing hours a day, so they can get used to the wind and sun. I put them out on a cloudy day, then it rained , but today they have full Texas sun. Most of them are doing fine, but there’s one that’s drooping, with flimsy leaves. The sun is too much for him.
You can put everyone through the same thing, it seems, but they come out of it with a different ability to cope.
