hope i didn't kill these flowers

They should be fine. It sounds like they were root bound anyway. Plants can get too many roots in pots and need to be cut back and/or separated. They drooped wilted because they got a little shocked. I think you will find they will do even better now.

What you have to do in order to complete a process like this is trim away some of the leaves. The plants have enough roots to support all of the vegetation of the plant. You just cut away half of them and your plants do not have enough root structure to support all of the leaves. That is why they wilted. Do not fertilize. You can kill them. What you should do is trim away some of the leaf growth or remove some of the leaves completely. They are plants. Plants are usually tough but some of them might not make it through this.

Your flowers should be able to withstand that, my friend. It's probably initial shock, and you'll need to replant them as soon as possible, in order that they get the natural nutrients from the soil, especially if they're flowering already. Good luck with them, anyway. Brightest Blessings.

Plants are simply amazing. When you treat them with TLC they don't seem to show appreciation. When you almost forget about them, they do just fine. I could never figure out why. Your plants will do just fine in their new home. Just good drainage and watering is all they really need for now until they adapt to their new container. The plant food feeding should wait until the plant has had a chance to settle down...it is healing its wounds right now.
