|Several years I planted a plum tree, it was planted in the pot it came in. When flowers come on the tree they fall off and I never get any fruit.|
|I think you have a Santa Rosa plum tree which is usually considered to be self-fruitful. However, your tree will set more fruit if there is another Japanese plum tree growing in your landscape.
Try one of the Japanese plum cultivars 'Burbank', 'Shiro', 'Beauty', or 'Gold' as a companion to your Santa Rosa and you'll see fruit developing on both trees.
