Hi, I had a huge branch rip off a Horse Chestnut tree in my garden in the recent gales and I'd like to know if I should treat the scar on the trunk where it was damaged to protect the tree ?
As you can see from the photo the damage to the trunk is quite large and is actually in a V shape at the bottom which I think needs cutting flush with the trunk so water doesn't settle in the damaged area and rots the trunk.
I think the large branch next to the damaged trunk should also be removed as it's about the same size as the one that came off, and although we don't get 85 mph gales every winter, it looks like they are too heavy for the tree so I might cut that off before it gets ripped off.
Any advice on what to do most appreciated
thanks
