I want a Bartlett and D'Anjou pear in my backyard in Fresno, CA. What rootstock should I use? I have a bare root Bartlett on OHxF333 and I think the D'Anjou is also.

Ideally, I want a small dwarf orchard where all trees are The soil is below avg (slightly amended clay) but not poor, I'll plant on a raised bed. There isn't much room but a spot in the corner (fenced between both rear/side neighbors) gets morning but little afternoon sun -- best anyway here in super hot dry summers? Being near the fence won't get much air-flow low at the trunk but should be sufficient as the canopy would be above 6' mark.

Would planting a semi-dwarf apple (MM106) or cherry (GM61) 12 feet away be enough room for air and to avoid over-spray?

Do you see any problems with this plan on those stocks?

Thanks in Advance
