VERY small cherries
We moved into an old house 6 years ago. It has a 75+ year old cherry tree. Every year the cherries are no bigger than their seed, so about 1/4". What is going on with it? We are located in ne Kansas and it is on the south side of the brick house. There was a 2nd tree maybe 150ft away but it was damaged. There are no cherries on the remaining tree this year. I have no idea what kind of trees they are/were so also don't know which kind to replant as a pollinator. The damaged tree also would only produce tiny cherries.

If this is consistent from year to year, it is likely the top portion of the tree died and the tree came back from the rootstock. Nothing you can do but replace the tree. No need for a pollinator for sour (pie) cherries but you would need one for sweet cherries. The sweet cherry Stella is an exception and is self-fruitful and therefore does not need a pollinator.
