Propagation

The beginner will normally secure his plants from a nursery and so the subject of propagation is relatively unimportant here.  However, rhododendrons frequently become a hobby plant and many hobbyists want to do some propagating for themselves.

Rhododendrons may be rooted from layers.  A low branch is pegged down into a trench and covered with two or three inches of soil.  Usually, cutting a tongue on the underside less than halfway through the branch on the part of the branch which is buried, thus leaving the end of the branch partially attached to the mother plant, will hasten rooting which may require several months.  The "tip" of the tongue should be nearest the mother plant.

Most rhododendrons are now grown from tissue culture plantlets or from cuttings.  Cuttings are usually rooted in August to October, in peat moss and sand or peat moss and perlite, under mist with bottom heat and with the use of root inducing hormones.
