Three and a half years ago I posted on the old HOS forums a happy discovery of mine in Alaska of a hybrid malus found with a natural tendency to spread horizontal branches.

Palmetta apple (f-1)
(still trellising along)

Parts may be hard to see but there had been a graft performed several years ago about a foot high on another renetka type crabapple that had existed there since the 80s by my brother. Moose recently stripped leaves on the left branches. The red verticle growth (not to become confused by bare background alders) is from the stock watersprouts after some serious bacteria killed the old tree above my graft of palmetta.

For me in Vancouver I did almost the same thing and the behavior is the very same on existing trees alwats to make great fast sideways growth when there is space on the side to grow. So if you or anybody wants more information where I will be next spring I can always send more pictures or free scions once I return from Alaska. I think John has my email so to find me find John first via his recent post about rust on pear with his email listed there. He is such an awesome contributor (like many others).

I do lots of research as part of what several us here in Alaska are involved with, and the named cultivar above is part of a group selected for health, which explains why it taste so bad and fruits only get to a golf ball. We have been testing it with many a pear and the results prove positive with asian pear most of the time.
