I was wondering if anyone knew the general differences between the different rootstock options for persimmons.
I know virginiana is preferred in most of the US due to cold tolerance, but is there a reason other than lack of a need for cold tolerance that they use lotus (or maybe kaki?) in places like CA? Are some more tolerant of different types of soils? Compatibility? Salinity? Do some affect precocity? Disease resistance? Other concerns? I have an in-ground outdoor lotus here and it seems very vigorous, which I suppose could be good and bad.
This link here (fairly old article from what I can tell), seems to imply that Lotus is not a good general purpose rootstock and seems to have some issues with Fuyu:
This link (from a 1982 publication) seems to indicate somewhat the same, that kaki is preferred. It also mentioned that those on virginiana declined. Kaki was purportedly the rootstock on the oldest orchards:
CRFG states that kaki is temperamental but I’m not sure what that means (difficult to graft? some seedlings are good and others not?), and virginiana as inconsistent (again, not sure exactly what they mean by that):
Does anyone know of a solid source for kaki seed or seedlings? Or a better source of information as to the benefits and drawbacks of each of these rootstocks?
I’m considering trying out a few trees in a greenhouse setting where cold wouldn’t be as much of a problem (temps only down into the low 20s). It would be nice to have a rootstock that liked those conditions, was vigorous, and didn’t send up root sprouts like virginiana.
