Container Tree Not Doing Well
I recently purchased a Zelkova Serrata Variegata tree to plant in a large container on my rooftop deck in Chicago. The tree was completely dormant. When I planted it from a container it was extremely rootbound and I tried to break the roots up but then thought maybe I shouldnt do that because I was afraid I would damage them.
The tree took forever but finally some buds began to leaf. They lasted for a while now the leaves are all dying and falling off. There are still alot of buds left but they are just leafing out and then dying.
I have been watering it regularly but not overwatering. I planted it in mix of 2-1 potting soil to compost. It has been in this pot for around 2 months.
Could it be rootbound? Should I dig it up now and score the roots? Is it too late? The tree itself looks healthy othe than the leaves dying...
