An easy method of propagation is layering, though this, too, produces only a limited number of new individuals. This method is based on the fact that if the young shoot or shrub is bent and inserted in the soil it will put forth roots. Some shrubs multiply in this manner in the wild, e.g. the blackberry, dogwood, etc.
If the seedlings are too densely planted in the pot they should be pricked out some 2-3 centimetres apart as soon as the primary leaves appear and the root has not yet I ranched, being left thus until the following spring, when they are then transferred to the bed.
For that reason, if the shrub does riot have a sufficient number of long, one-year shoots close to the base it must first be cut back so that it produces new young shoots.
The simplest and easiest method of propagating shrubs is by division. This way, of course, it is possible to produce only one or at most several new individuals, but one great advantage is that they are usually sturdy enough to be planted out in the open immediately. This method can be used to propagate shrubs that continually shoot out new suckers from the base and have a tufted habit of growth.
These include the Japanese quince, mock orange, Oregon grape, heath, snowberry, some species of spiraea, staghorn sumach, dogwood, Japan rose, raspberry, etc. The best time for division of roots is in the spring. The entire shrub is lifted from the soil and divided into several sections with a knife or a sharp spade or else some of the earth is worked away from the side of the shrub and the individual root suckers are separated from the mother plant.
A similar method, known as stooling, is used to increase choice varieties of the hazel or to produce a greater quantity of rootstocks for budding or grafting fruit trees. Shrubs to be increased are cut back close to the ground in early spring so that they will put out as many shoots as possible. As these shoots grow they arc covered with a mound of soil up to about 30 centimetres high. During the summer the shoots put forth new roots and in the autumn the soil is removed and the rooted shoots are cut away from the parent shrub and planted out. This method is sometimes used to propagate certain varieties and species of Philadelphus, Deulzia, Hydrangea, and, Syringa.
