This old red oak in front of my house has some dead limbs. I'll need to remove those at least, but I need to decide whether or not to remove the whole tree.
The tree service who did the estimate said the entire tree may be dying and that if I just cut off dead limbs I might end up cutting more of them off in a few years. It may be a better plan to just cut it down. I need to figure out what is going on with the tree--why it appears to be dying, and if it is actually dying.
These are the possible reasons for the dead limbs I have come up with so far. Please shoot them down and propose new reasons
- Tree is being crowded out somehow by the Horse Chestnut butting up against it. This is suggested by the fact that the dead limbs are mostly the ones that contact the Chestnut.
- Tree is having soil or root issues which are killing the tree. This is suggested by the fungus growing at the root (according to the tree-cutting contractor).
- It is simply dying of old age. The house behind it is 100 years old. The tree may be up to 30 years older than that. Northern Red Oak usually lives for 200 years, which suggests that it is over the hill, but not near the end of its life span.
I need to answer these questions in order to decide to kill it or keep it:
- What is ailing this tree?
- Is it curable?
- Should I expect much more of it to die in the coming decade?
