Grafting of pines
« on: October 05, 2009, 10:16 PM »
Was wonderin of anyone knew if P. mugo pumila can be grafted to JBP stock? Got a P. mugo pumila that has 2 branches that would make decent stock themselves. Thanks in advance  :)

I've never had a graft take so take this for what its worth.  In the meantime, this link shows that P. mugo is more closely related to P. thunbergii than P. parviflora.  It is my understanding that the best odds of a successful graft comes from plants as closely related (or closely classfied) as possible.

Interestin article. Here's my take after readin the article. Siberian Dwarf Pine- Pinus pumila(I'm assumin also known as Pinus mugo pumila-what it says on the pots) is in Subgenus Strobus(white or soft pines) subsection Cembrae. Where Mountain Pine- Pinus mugo(assumin also known as Pinus mugo mugo) and Japanese Black Pine- Pinus thunbergii fall under Subgenus Pinus(yellow or hard pines) subsection Pinus. So goin by that classification P. m. pumila and P. thunbergii are not closely related. Now if that article is sayin that P. pumila is strictly pumila and not P. mugo pumila(like it says on the sticker tag) then is it possible that the 2 pines I have are a cross? Cross of P. pumila and P. mugo? Again 2 different pines in classification. I'm understandin that it is not feasable to graft a white/soft pine to yellow/hard pine stock. BUT I can give a excellent example of this. I do have a P. parviflora(white/soft pine) that is grafted onto P. sylvestris(yellow/hard pine). So just how closely related does a pine have to be to another to graft successfully? Ok, enough babblin LOL. Just thought I'd give my thoughts on this. Now onto the pine in question. Below are pics of where the branches meet the trunk and, cheaply tryin, pics of their canopies.

The problem is that the JBP base will grow much faster than the pumila scieon, leading to a potentially difficult to manage graft junction.

Ok, thanks John. I may try airlayers on em. If they don't take guess they'll end up in the dump pile or end up there if I decide not to airlayer. Bein too frugal LOL.
