Air-Layering

What rate of success can be expected when air-layering evergreen magnolias/michelias? Is there a preferred medium or would sphagnum moss suffice?

 

sphagnum moss works great, i use each time i air layer anything!

 

Hi, TH. I've had success using sphagnum moss on other plants but wondered if a different medium would be better for magnolias; a local nursery seemed to be using something other than just moss on a stock plant.
