Hi guys
I looked at a Horse Chestnut today that had cankers all the way round it's circumference. It also has chestnut leaf blotch - Guidnardia aesculi.
The client wants to save it, I said I may be able to prolong it's life by lifting the turf around it and replacing with fertilizer and mulch. No pruning is needed.
The cankers will be choking the vascular system or at least restricting the flow of nutrients up, sugars down etc.
I also suggested complete removal and replace with new trees.
Is there anything else I could do?
The client

loves her tree.
