Cool, thanks. Separate topic that you may know about: grafting female scions from spicebush on to male plants. I think it should work, but my (limited) internet search hasn’t yielded any confirming sources. Do you know if it would work and know of anyone with experience doing it? I have a very nice female spicebush and I have found about 10 more males on my property. Is it possible to mix the sexes using grafting? I plan on starting some by seed and will be trying softwood and hardwood propogation.
Apple rootstock affects color and BRIX
This was a pretty good video clip that covered this.
Apperently, rootstock does have an affect on apple color, maturity, nutrition and brix so it also affects flavor. The flavor of some apples may be intensified depending on changes to water availability at maturity as well.
