HI all. I'm new here but not to avocado trees. I'm in southern Or where we do get very cold in the winter with some snow thus we built a large greenhouse 24' x 48'. I have several trees in it avocado, lemon, orange, fig. My avocado is a wurtz and produces pretty well but every other year.
Can anyone suggest another small avocado tree that produces every year? I'm considering grafting a scoon from something else but haven't figured out what would be a good choice. Any help out there??
