What's the largest air-layer you have ever successfully done?

[Hack Yeah!]

Yes, I was considering simply doing a massive pruning spree and waiting for a year... but if it is possible, I'd love to be able to save the material.

The tree is approx. 30' tall. The highest I could reasonably do an airlayer would be about 15' off the ground - and even that would require creative work with a ladder. Assuming the air-layer is successful, I now have 2 x 15' trees to work with for propagation.

If it's for propagation purposes why not go ahead and set layers every few feet, assuming there are branches and leaves, then just keep going as high as you can

That... Sounds like an amazing problem to have

Have you learned any arborist climbing techniques?
Probably a hell of a lot safer to do it with ropes

I air layered a Taxus cuspidata that was 3.2 inch in diameter. It took two growing seasons to get enough roots to separate it.

Following this thread! This spring I'll be starting some air layers on a persimmon that sits on the corner of my property. Might have to compare notes.

I separated elm layered from the forest. It's about 1,5 meters high.

I'm barely experienced in air layering, but if I understand what I've researched, I think any layers above the lowest air layer would get less and less resources, and therefore would have decreasing chances of of success. I attempted this on a branch of a hackberry a couple years ago, and none of them took. I was careful to leave side branches with vigorous foliage between each layer. I tried a single layer on a separate branch, and it survived a year after separation. Then I put a couple trees in front of it and dehydrated it to death.
But maybe someone else has had success with this method.

I always think about this video from Graham Potter when this question is asked... Goodness it's 15 years old!!! LOL I remember when it was released!! Oh my...
