The mysteries of my Frankencrab
Just some thoughts as this Frankencrab project has pressed into the end of June.
harvestman got me thinking about something to do with this tree.
I purchased this property in 2008, and according to neighbors, this tree has been there since they can remember, which for one of them is since the property was built out 30 years ago. I dont know how accurate that is, but I have been wondering what this tree's true height potential really is.
I've done some reading and it seems common crabapple rootstock is either M.7 or Ottawa 3. Ottawa 3 is pretty small, around 10 feet according to documents on the web. M.7 is a bit bigger than that, and its possible this tree is on M.7 but I dont see a graft union on it at all, no seam, no change in bark color.
This tree was allowed to do whatever it wanted for a majority of its life. It was in the shade up until last year, now it gets sun 7AM to 4PM. It was perfectly content with mediocre growth and leaf size until I halved a lot of branches last February to get new growth to graft onto this year.
Once I halved just about everything on the tree I really woke it up, leaf size tripled and it put out root suckers like a banshee. I had a new vertical leader come up at the top where I cut off a lot of wood, and no lie it was at least 6 feet tall in 1 year, so that would put the tree close to 16 feet tall with that growth.
Fast forward to this year, grafting is done (for now), I've got Freyberg, Calville Blanc d'Hiver, King of The Pippins and Belle de Boskoop on the tree.
You'll see on the left, on the south side of the tree, I left the weeping crab apple growth on it to protect the trunk from southwest injury and its done exactly that.
Now to what I've been thinking about...
I dont see a graft union on this thing, so could it be a seedling crab apple?
I grafted Belle de Boskoop onto an injury callous vein to make it my new central leader, and I did that first week in June, and its put on a bit of growth already.
I wanted a tall top of the tree, so that is why I selected the Belle de Boskoop to be at the top and north side of the tree, here is the north side scion...
Look at the size of that thing! Compare that to the other half of the cleft that didnt take!
So, what do you think? I think im going to get a tall central leader on this thing, but how tall? It remains a mystery to me. I planned on doing some tree work from the roof already, but if this is a seedling root, and I have a notoriously vigorous variety as a new leader Im wondering if I'll be getting more than I bargained for.
