What is your potting mix? It looks very heavy on the organic side and everything I have read and used suggests a well drained, coarse, inorganic mix. I used a 50:50 mix of pumice and haydite, misted and watered the tree several times a day at first then backed off a bit later on. The mix is full of nice white roots now and the tree grew new foliage this summer. Hopefully will make it through this crazy winter and bud out like crazy next spring.
