We have an apple tree in our garden that has produced almost nothing for about the last five years and was starting to struggle before that. Every year I've thought vaguely that we must get round to having it removed. It was there when we moved in 19 years ago so don't know how old it is.
This summer I've noticed it's full of apples.
I feel like I'm in one of those fairytales where things suddenly spring back to life but, fantasy aside, what might have caused this to happen?
