Cornus Controversa Variegata - Help
My beautiful tree which has been in the ground about 15 years but has only ever grown to about 8 feet has got severe dieback on the branches. It's always had the odd bit that died back but now it is extending to large branches. Does the tree have a shelf life or is it the drought as we have had virtually no rain since the spring. It had a lot of growth this year below the graft which I took off recently but to no avail!
