Q.We Have an Apricot Tree and a Plum Tree
When they start to bear fruit, they only get about as big as a grape tomato and then fall off. Is there a specific spray for these trees? We have tried a number of them, but something helps. Would appreciate hearing from you sorry, first half of question was cut off. . . I’m talking about apricot and plum trees.

Premature fruit drop is normally the result of poor pollination or an insect problem. Here is an article that you may find helpful (the info applies to plums as well): https://www.gardeningknowhow.com/edible/fruits/apricots/apricot-tree-not-fruiting.htm
Overbearing is another possibility. When the fruit is pea size, begin thinning to prevent fruit drop. This will reduce the energy of the tree so it can put more into the production of fruit. If pollination/fertilization is at too great a level for the tree to sustain, all of the set fruit will simply drop. You can also thin the blossoms rather than the fruit.
