I have very limited gardening experience.....

We moved into this property which had a large, well tended garden, by a
retired couple.

It had this lovely Plumb Tree which produced a huge harvest each year.
However, I had not pruned it for 3 years and branches had grown too
large and the plumbs were threatening to bring them down.

Must be one of those rare plumb bob trees... be alert to plumber's
crack.
