I hope they recover.
I bought some gorgeous peppers in a pot that, it turned out, were meant to stay potted.
But I split them and transplanted them and that really et them back.
But I was not familiar with container gardening in those days.
Next year, I’m going to try those Chinese 5 Color peppers in a couple large pots and see how they do.
I guess they don’t get too big and are considered ornamentals anyways.
But they have a really short days to maturity so I can start them early on the porch and plant some later as succession planting.
FWIW, I’ve had much better success with pepper plants in pots than in our (dubious) ground. It may be the roots are particularly needful of good drainage? They (pepper plant roots) always seem “fragile” to me, too, and then slow to recover. But... in this case the plants must have germinated from seeds stuck together. So, I did the best I could with the strongest plant, and “we’ll see” about the weaker ones, I guess. The other option would have been to just chop the weaker ones @ “ground level”, but then there’s even more dead root material intertwined with the best plant’s roots. I don’t know if that’s problematic or not, but, it seems like a recipe for disease and rot.
Pepper plants do better for me in “partial sun” than full sun, too.
However, I’m beginnning to wonder if a problem with potted plants is that the soil / potting mix in the pots gets too hot on sunny summer days here. I’ve already started shading spots in the ground and pots of tomato plants not shaded by the plant itself. It seems to help.
