grafiting American Holly for alkaline tolerance

Posted by smivies z5b ontario (My Page) on

Has anyone every done this before? Some selections of I. opaca has really good winter hardiness but our calcacerous soils tend to cause serious chlorosis.

Has anyone every grafted I. opaca onto other species of Ilex?
Any thoughts of compatibility between I. opaca scion and I. pedunculosa or I. x meserveae rootstocks? What about using a zone 6 Ilex aquifolium variety?

well in general, I never grafted a tree. I would think the tree be weaker, or extreme difficulty if a new gardener. Cuttings are way easier, or just collect seed, or buy a good tree from a reputable grower. Hope it works for you

What a crafty way of bumping a question down the list when clearly nobody knows the answer.

i was going to knock it down.. by wondering why a Canadian would allow an American holly in its yard..

or why customs would let it across the border.. since it has no inherent Canadian content.. lol ...

but i didnt .. and now i can tell the joke.. guilt free .. lol ...

i am really surprised.. google failed this.. hmmm

@Ken...

All kidding aside, the northern limit for I. opaca generally matches the southern limit of glaciation. North of that, it seems that the relatively young soils of calcacerous origin have not been sufficiently leached of lime (in addition to colder winter conditions). Going west, Ilex doesn't fair well anyway in the more arid climates which also have alkaline soils. So...there has never been a commercial need to graft I. opaca to a better adapted rootstock for alkaline conditions.

There has been work on Rhododendrons in this regard.....I was wishing too much for parallel Ilex work.

I was hoping a hobbyist/enthusiast had done it? I guess I'll have to try it.
