Does someone know the answer to this question? If most JWP bonsai are grafted to JBP roots, why is it that JWP still need a colder winter dormancy period than JBP?

I'm no expert on this subject, but I can tell you my experience. JBP thrive here, but I can't grow JWP grafted on JBP roots, so in my case it must have to do with the foliage, maybe the question you ask has the same answer, the foliage needs a colder winter dormancy, my 2 cents.

keep it green,
