Air layering

Air layering of Limonium dendroides.
In air layering (or marcotting), the target region is wounded and then surrounded in a moisture-retaining wrapper such as sphagnum moss, which is further surrounded in a moisture barrier such as polyethylene film. Rooting hormone is often applied to encourage the wounded region to grow roots. When sufficient roots have grown from the wound, the stem from the parent plant is removed and planted. It takes about three months for the new plant to become mature.
last two weeks, we went to beth shalom organic farm to do a research for science about air layering, grafting and cutting. it was a fun experience. we learn about natural vegetative reprodruction.
