I have an apple tree in my garden whose trunk is now about 80% hollow. One of the main branches is similar. It fruited pretty well this year but is clearly on its way out.
Should i chop and replace it now (i want to use the same/close by spot) or leave it until it died completely?
If I am replacing it, then by starting now I should have nice tree in 3-4 years rather than waiting another few years and then starting again?
