Asian & European pears on same tree?
Is there a reason that no one sells combo trees with both Asian and European pears?
I realize that there are pollination issues, but I've seen trees with 4 or 5 varieties, which would be enough to have two of each type. And the multi-grafted Asian and multi- European pear trees offered by Raintree are both grafted onto the same rootstock, so the reason isn't rootstock compatibility.
I'm down to the last two spots in my yard that I can place a tree without causing marital discord, and one of those needs to be a pollinizer for my plumcot, but I'd really like to squeeze in both Asian & Euro pears somehow.
If it's a reasonable idea, but not commercially available, I'm game for trying to make one myself, in which case, I would prefer to start with a tree instead of rootstock - can you graft Asian to European or vice versa?
