Can A Santa Rosa Plum Tree Also Bear Other Kind Of Fruit?

Question

I have a Santa Rosa plum tree with great production for years. This year, after harvesting plums, it is now producing a fruit about the same size, but in yellowish green color and smells like peach. I am quite sure that it is not a plum. There are more than a hundred of them on the tree right now. Is this normal?

If the grafted root stock takes over, then yes. It is necessary to keep any growth from the base of the tree cut. By this time, since they are fruiting, it is likely too late. Here is an article for more information:
