The demise of my plum tree.

In our mature garden we both had our “set” chores. My partner, who died last year, was the “pruner” and sadly I was too busy with “my” chores to take a whole lot of notice of his! Last year armed with the pruning book and pruners I set too (carefully) and did what I thought was quite a good job. The tree had produced the most magnificent crop. The week after I’d pruned it all the leaves fell off and it never recovered. Please tell me I didn’t kill it and that p’raps it had come to the end of its natural life!?
