I would say... give them some time to acclimate... they'll bounce back if everything is okay.

And I'd go with an organic solution for the moth issue. You don't wanna eat anything that's been "chemicalized"!

I am using Mrs. Meyer's dish soap for the spray, just a little squirt in a spray bottle of water. I hope it does okay. Last year I used Dr Bronner's, but they didn't have it where I was shopping. I didn't want to just use my normal Dawn though, that seemed like it might be a bit harsh. I hope the kale bounces back! I have been looking forward to it!

If the plants have what they need, they'll be fine.

I've been gardening, both indoors and out, for most of my life... and if I've learned anything, it's due to the science and basic physics offered by Tapla in his articles.

Read the link below... you will be amazed at how simple it really is...

Have you read something that suggests that the dish soap spray is going to be effective on caterpillars, or have you used it before with good results? If not, I wouldn't hold my breath. Hand picking is my preferred method, but I do keep some Bt in reserve in the event that I can't keep up. Spinosad is also reported to be effective, but I prefer to avoid it if at all possible since it's effects aren't limited to caterpillars.

No, I've only read that it kills soft bodied insects. Not sure if caterpillars count. I've only used it when I have aphids, but if it works for other stuff, I'd give it a try. But I'm okay with picking caterpillars. I was just wondering if maybe all the touching/handling was stressing out the plants. I mean I try to be gentle, of course...
