Looks great! You might want to keep it in a relatively shady area for a week or two after doing a bare-root potting. Many people say you should hold off on fertilizing after planting or re-potting however I personally don't think that is necessary. Perhaps do half dose for a week or two. Good luck!

Beautiful trees! I agree with Brettay. Definitely be careful with the sun, but as far as feeding, I figure mine already have slow release fertilizer in the mix, so adding a little FP and vinegar does not hurt. Giving a half dose is a great idea. I have done that for all my trees and they have started growing usually within the week.

Thanks, Brett and Laura. I opted to begin feeding lightly, and adding vinegar. There's no sun to speak of (temps here have been @51-63F, heavy cloud cover, our typical cold summer weather in S.F., and my tiny space is very sun-challenged anyway, even when we have sun in my neighborhood); and as the wind has been much gentler than usual, I opted just to leave Kishu with its sibling citrus. So far, no signs of shock or dismay, no leaf drop, etc. Maybe too soon for that--but I'm a bit surprised. I really went at that root ball, hacked away an awful lot of it, and I wasn't all that gentle, either. Will update in another week or two as to any progress or decline. Hoping for the best!

I hope your new addition thrives in the new container and mix!
