Three of my wisteria trees were doing very well in their old pots. I recently repotted them in early spring using much more draining soil. I also exposed some roots. This afternoon, I noticed some wrinkles on the roots of one wisteria plant. After a scratch test, I discovered that a lot of roots are rotted inside and also half of the tree is dead even the folliage looks completely normal. I checked another tree that look absolutly healthy, some root are also rotted. I realy want to know what happens here. My camera phone is not working to show the pics. What really bothers me is that the old soil was not draining well at all and the old homemade pots had water logging but the wisteria thrived. Now with better condition, they are rotting away
