I planted an apricot tree 4 springs ago, and it's the only apricot tree in the yard; there are, however, two peach and a plum if that matters. The tree has grown from 5' to around 15' during this time, and there is always a lot of fruit throughout the tree. However, within a couple of months, there may be only 2 or 3 apricots remaining, as all the other fruit drops. Does anyone have any suggestions? I'd love to have some fruit this year. Thanks
