I have a bonanza dwarf peach tree grafted onto Hansen 443 rootstock. I'm trying to learn about the rootstock but can't find any information about it. The closes I can find is the Hansen 536, but my grower was clear that it is 443. I know bonanza peaches are genetic dwarfs and often grown on their own roots, so I'm not sure why this was grafted. Just wondering about the rootstock properties.
Anybody have experience with this rootstock?
