When I moved into my house I inherited an out of control very old apple tree. I had it pruned way back and the guy said it was a dwarf variety that had gotten out of control. Well I've gotten apples on it before but not many but this year there are a ton. It is a green apple of some sort but I don't know what kind it is. I'm pretty sure its not a granny smith. I don't know when a good time is to pick it and know when the apple is ripe enough. I picked one today and it seemed sour to me but I don't know if thats just the variety it is (maybe a baking apple variety) Can anyone help? Thanks!
