i heard a rumor that coconut coir can be used for air-layering--- is that true? i've air-layered things with sphagnum moss, but never coconut coir. i'm going to be air-layering a rubber plant very soon. thanks in advance for your help! :D
One advantage of sphagnum is its natural anti-bacterial and anti-fungal properties. For example it can be used for dressing wounds. That is not to say you cannot use other materials such as coir, but I haven't tried it myself. The "[GOOGLE]Rooterpot[/GOOGLE]" is an example of a product designed for air-layering using an ordinary potting mix.
