Incrementum Interruptus

OR Interrupted growth.

Why do some newly grafted apple trees start to leaf out and then stop?

The tree pictured, a Loyalist on B9, has had that same amount of growth since the first of June.

During our drought, I watered once or twice a day.

Maybe it’s drown? More likely the graft hasn’t taken. But there’s still hope. I had an apple graft push more than that and then completely dry up. I hung in there and a couple of weeks later it took off and is now huge.

As mentioned above…the graft hasn’t taken yet I’d say.

There’s enough energy in the scionwood to push the leaves that are shown. If the graft takes you will see that sprout lengthen by a few inches, then you know it’s taken.

If those still furled leaves start drying out, then I’d say your graft is in trouble. As long as they are green and fresh I’d just have a bit more patience.

I’m not saying it is the case in this instance but i had grafts once take months to take which was due to partial compatability. Have had grafts delayed in taking because i had some not perfect scions and was able to align good to one side but not the other. Cambium contact , temperature , moisture level etc. can all be issues. Usually it is not enough moisture in my case.

Thanks. I’ve had greening up many times before on failed grafts, but no leafing that progressed as far as this. I’ll be patient, and two other Loyalist grafts were successful this spring. I planted so many in hopes of getting at least one to succeed, so if this one takes off, it will be a pleasant extra.

When grafts are on the edge of success they can do this. I had a Chestnut graft this spring that leafed out a bit, then stalled at a similar spot as your tree for about a month. The trunk put out a bunch of adventitious buds which I religiously rubbed off almost every day, and eventually the graft decided to get going. I’ve also had plenty that never got going.
