I have what I think is a Southern magnolia, whose a few limbs have expanded over my roof. I'd like to try to make use of the growth on it instead of just cutting them off, by an air layering. I've done a few on newer growth off the tree, but these are larger and older. Included is a picture of one of the overhanging limbs. I'm wondering if an air layer might take at the thicker, lower point (1 3/4" diam maybe) before the split to two thinner (but long-ish) branches, or would I have better luck with making two instead above the split? Or is the growth too old to take? I did have great success last year with a mature three limbed leader off a ficus, so on that it worked on a fairly mature tree; but this magnolia has thicker branch diameters, and likely well older growth than the ficus branch. Thx
