Hey : )
Maybe some of you rememberers when I’ve got home with a tall nursery Ginkgo which was left to dead by the staff.
I’ve did an air layer immediately, which wasn’t successful. I didn’t separate in time and I’ve let the layer without protection on freezing winter.

Now I’ve got some crazy fluff going on and I don’t know where to start the work with it...

That was the tree’s first day with me (May, 2018). Notice the lack of foliage and branches on the lower 2/3.


Here is a picture from the air layered trunk at the same month.


And this what’s going on now...

Under the chop site where the air layer was, on this spring the tree developed a crown-ish thing in seconds, literally from nothing. (I’ve waited just some leaves, hence I’ve read everywhere first year the leaves, second or third year extending to branch.)


Those branches just extending and thickening. I think the pace slowed down since the beginning of May.


The full tree looks like this today. Far from what I expected, cause I wanted around the half of that height. I didn’t believe that it could sprout out. At the winter it was just a straight stick...


I’ll throw an other air layer on it at the next spring, but this year I’d like to start to work with those branches before they became thicker than the trunk.

Since is acting completely differently than all of my other trees... My question for those who keep this species:
When and how to prune this thing?

Looks like I did it right... : ) I left untrimmed just the leader and the branch under the future air-layer site. Budding back from almost every node.

Hey, it's looking good, Felidae! Congrats!

Let me try to explain what a learned about Ginko's, I find this a very difficult tree btw
Time to prune ginkgo (Japanese nut tree). Now, ginkgo's hate pruning and repotting. So you do this sparingly.
Ginkgo's are usually formed in the flame style, a very compact design close to the trunk, in the form of a flame.
So you have to get a branch close to the trunk.
The principle is that you wait to prune until a branch has more day 8 leaves. You cut that branch back to 6 leaves. We will then prune the lower three, the three leaves at the bottom. Leafy green road, stalk remains standing.
With this pruning method we try to stimulate a dense branching, a compact growth.
