What's with my Italian Plum?
I live in the Pacific NW, and have a beautiful, healthy-looking Italian Plum tree that I planted about 5 years ago. It puts out lots of blossoms each year, but it hardly ever produces any plums: last year I got 6 plums, this year it looks like there is one! I have 4 other fruit trees nearby that were planted about the same time -- combo and single species -- and they are all well-loaded with fruit. Can anyone suggest what might be going on?
