When you got them home, were they sitting in the sun? They may not have been well hardened off by the grower.

Well they were inside a garden center at Walmart. Could have an effect. I would think not though as they are 8-12 inches tall.

Were they in the original containers when they started wilting or did you transplant them prior to them wilting?

"Yesterday I plucked them out and added garden soil. Any tips?"

Agree with Rodney. I'm not understanding this comment. Are they still in the original pots or what. If so, why? Also remember that excessive watering can also cause plants to wilt and peppers especially don't like it. So when you say plenty of water, what do you mean specifically..

Sounds to me like they were wilting before any plucking was done. But yes, peppers don't like to be overwatered.

They were in peat pots before they started wilting--a couple days before planting--and yes, they did start wilting before transplant to garden. It has rained about 3 day here, but dries out in between rain. When I pulled them out and replanted, the roots were not soggy.

Peat pots were original pots.

Have they not perked back up after planting?

Not yet. It has rained a lot in the last 2 days though. Going to let the soil dry out and see what happens.
