Hi, seems I did something wrong or to much when repotting my quercus suber like a month ago, see pics, did I prune the roots too drastic maybe? Any idea what I can do to save it?
Hi Simon, I’m sorry to read that your tree isn’t doing well. Maybe you can get some helpt but it’s difficult to tell what’s causing the shrivelling/dying of the leafs by the pictures alone. How much of the roots did you cut? Did you wash the roots or did you keep parts of the old soil? Was the tree then secured strongly to the pot? And did you fertilize and if so at what point after repotting? Was the tree in direct sunlight after repotting?The more info you give the better a diagnosis can be made.
My guess at this point going on the pictures would be that you fertilized too soon and that this burned the roots. But that’s an initial guess.
Plenty of things could have gone wrong during the repot…
I would suggest greenhouse / away from wind, put it on the ground and mist daily even twice a day rather than water the pot. Water only when soil tries out.
If greenhouse not available, plastic bag and keep it misted inside as required.
DO NOT fertilize!
Hopefully you will see some new leaves in few weeks time 
I didn’t wash out the roots but I think I might have cut too much, but no fertilizer yet, and just a few hours a day sun. I’ll try moving to even more shaded place and mist twice a day. Thanks everyone for trying to help!
Oaks are more like conifers for repotting in my experience. cutting too much off and removing too much of the original soil may be the cause. give it time to recover and don’t over water or fertilize. it may recover but it might take a while. If not, treat your oaks more gingerly in the future when repotting. I learned this the hard way buy killing at least one tree. it is not a typical deciduous.
My recommendation would be to go hands off for the rest of the year with a good balance of water and oxygen. Hold off on fertilizer for another several weeks. Your oak will go dormant during summertime and then start growing towards the tail end, where you may need a light liquid fertilizer. It should recover, but just let the tree do its thing. Probably best in some morning sun with afternoon shade and protected from wind
Thanks everyone, I’ll do as you suggest, and hope for the best
