Give em time, all plants take awhile to get their roots situated and once they get their roots down the above ground portion you are seeing with respond. This may take a couple or a month or longer. Just keep them moist, baby them along. If you notice the hot sun makes their leaves droop you can put something in front of them to shade them during the hottest part of the day for a couple weeks until they adjust. I fertilize my boysens with miracle grow every few weeks and they have really taken off. I'm in just the secon year and already have quite a few berries. Good luck.

Yes,keep them well watered and it's probably okay to prune them back a little to let the roots catch up with the top.
I usually soak bare root plants in water for a couple hours before planting,but if the soil is kept moist,that should do it.
I've read they like compost towards Winter. Brady
