Very hard to determine based on your limited revelations. The size of the apple
may be a clue to the possibility that this is a crab apple tree. The only apple
I know
of that is so small is a Pitmastin Pinneaple, but that one is sweet and
russetted.

I just moved into a house with a couple of apple trees in the yard. The
apples are light greenn, approximately golf ball size, and incredibly sour.
Too sour to eat off of the tree.

Location is Calgary, Alberta, Canada.

Any idea what kind of apples these are?
