Picking Cherries

In my front yard, I have a Macintosh apple tree,  a plum tree and a cherry tree. The apple tree has only a few apples this year because the tree is taking a rest from last year's abundant harvest. There are two small green plums on the plum tree. I have not had much success in getting the plum tree to bear fruit.  In the five years since I planted the plum tree, this is the first time that two plums formed even though the tree has produced flowers for five consecutive years.  The cherry tree that is over 25 years old is still producing cherries and I have invited friends to pick the cherries. The tree is getting old and I have had to saw off a number of dying branches. The Cherry tree has been grafted onto a Nanjing cherry tree so the roots of the tree is really a Nanjing cherry tree. In my back yard behind my greenhouse I have another Macintosh tree and a Nanjing cherry tree.  The cherries from the Nanjing cherry tree produces small sweet pea sized cherries.  The cherry tree produces marble sized cherries and have a bit of a tart taste.  In the backyard , I also have a raspberry bush and a gojii berry bush. In front of my garage are three blueberry bushes. And finally, in the greenhouse, I have a potted peach tree  and six fruit bearing Fig trees that originally came from Italy.
