Air layering is a method of propagating new trees and shrubs from stems still attached to the parent plant. The stem is wrapped with damp moss to encourage roots to form.

Air layering is an effective propagation method for some plants that do not root readily from cuttings and which often lack low-growing shoots suitable for conventional layering, such as magnolia, hazel, Cotinus and flowering Cornus species.
Other suitable plants for air layering include: acers, camellia, Chaenomeles, daphnes, Ficus, Forsythia, Hamamelis, jasmine, Philodendron, rhododendron and azalea, lilac and viburnums.
Layering can be carried out in autumn or spring. Deciduous plants respond well in either season, but evergreens respond better to spring layering.
It is important for plants that take a long time to root to use black plastic rather than clear plastic, as light can encourage the growth of algae in the damp conditions inside the sleeve. Clear plastic is acceptable for speedy rooters such as Ficus.
