Grafting sugar maples
I have a large big tooth maple (a. grandidentatum) , which is sometimes listed as a subspecies of sugar maple (a. sacchrum ssp. grandidentatum). It's a great tree for this part of the country. The standard sugar maple is not. I do not think there are any cultivated forms of the big tooth subspecies however.
Since it is purportedly a sugar maple I think I should be able to graft sugar maple scions onto big tooth understock. Has anyone heard of this or tried it? Am I correct in thinking it would make sugar maple clones more suitable for this region?
I like the 'apollo' variety of sugar maple. dwarf tree with huge full sized leaves. thanks
