Pretty old apple tree in the garden which produces hundreds of not-great-tasting apples every year looks like it’s in a bit of a state. I had to cut back a weird branch that had been cut before, presumably because it shot out horizontally, and there’s a ton of rot.
It’s not in danger of hitting any buildings if it ever does fall, although could maybe take out a distracted child or two if I’m lucky.
Is there anything I can do to save it?
The same principles should apply to any woody perennial plant, but maybe not exactly. You still don't want them planted too deep, but they might not have a visible root flare. Since they are smaller, faster growing plants than trees I think they adapt better to inconveniences. But don't quote me on that. They are technically covered by arboriculture but I do 95% of my work with trees. Vines and brambles aren't really my area of expertise.
