I don't think so. White oaks can be grafted but I think most varietal red oaks are done from cuttings. Check the link of Pavia nursery in Belgium.

Are you sure, I believe it is possible to graft red oaks as well.... I was concerned about the rootstock providing necessary iron

There are more incompatibility issues amongst the red/black oaks than with the white oak group, but some folks are grafting them - and I've seen discussions on another list just this week regarding grafting pin oak onto Shumard and other species that are more pH tolerant, and it seems to work well.

Hi lucky,

do you mind sharing some links to those discussions? very interesting indeed.....
I wonder what other rootstock can be used....

osprey,
Can't link to 'em, as it's a 'restricted' discussion group.
Long and short of it is that, several folks have had some success - albeit with low numbers of plants - grafting things like Q.palustrus and Q.lobata, which don't fare well in a particular area or soil type onto appropriate understocks which are well-suited to the growing conditions.

Can try to check back, but I believe the pin-on-Shumard combination you mentioned in your original post was one that had worked well.

Hi lucky,

If you can double check it would be nice... I also believe pin and shumards are compatible....

What is a problem with Q. lobata? why would you like to graft it onto something else....

Have not grown lobata here - well, not in years - but evidently there's something about soil/moisture or something that it just 'doesn't like' on its own roots here in the east - but grafted on bicolor or macrocarpa, it seems to do just fine - or so I'm told.
I do have one small graft of Q.macrocarpaXlobata growing here; expect the hybrid will be just fine.

I've been grafting members of the white oak group for years - using mostly macrocarpa rootstock, as that's what I have readily available.
Just started trying a few red/blacks a year or so back; had decent success fostering grafts onto some young M.rubra trees planted alongside the driveway until I can get some more seedlings going for dedicated rootstock use.

I have a small lobata in the ground for almost two years now.. so far so good. Do you happen to have pics of those macrocarpaxlobata? I bet it is a very interesting plant.
Have you been able to graft any pin oaks onto rubra rootstock. I wonder what other rootstock may be compatible. The little I have read tells me that red oaks are extremely hard to graft, with possible incompatibility issues many years after grafting.

Just grow a Shumard - far better tree all-around IMHO.

I have 4 or 5 shumards already.. I really would like to have a pin tho... it has a very distinctive branching pattern...
but you are right, shumard is a very good tree, and does very well around here...
