I had mexicola, it was not worth growing for us. Too small, seed too big, poor bearing, short season. I realize many people like it I'm just giving my honest assessment. Hass, fuerte, sir prize, reed, jan boyce, sharwil, green gold,.... they all crush mexicola. Its all relative. I also realize those varieties I mentioned won't all grow everywhere else. Most grow poorly in FL. Even mex grande I think is mediocre really. Ill probably top work the tree before it gets 50ft tall.
If you have a big mexicola tree and the other types will grow for you then you should graft some of them up.
