Does anyone had any success airlayering a coastal redwood?

Joe,
The video is about Bald Cypress (Taxodium distichum) and dawn redwood (Metasequoia glyptostroboides). Both deciduous and the Coast redwood (Sequoia sempervirens) is a evergreen. They are totally different and not related in anyway to the Coast redwood.

Sorry Pierre, I thought that had some info in there for you.

Yes: after care, with all layered material, is very important. I kept mine moist and out of direct light.

How much time did it took? I have been trying since three years… The bark and cambium keeps getting bigger but no roots. I refreshed the cuts this spring, widen the gap (2 inches)…but the part I want to layer is getting weak. I don’t think it will survive another year but there are some new sprouts emerging. I will wait and see.

Are the any branches or foliage below where you are attempting to air layer?

Yes plenty of branches. The whole tree is four feet tall and I am trying to airlayer the top 12 inches where there is a large bulge creating a big inverse taper.
