ON THE PROPAGATION OF VARIOUS KINDS OF SHRUBS AND PLANTS.
Besides sowing seed and rearing plants from them by transplanting, there are many other ways of propagating plants, namely, by off-sets, suckers, layers, divided-roots, cuttings, and pipings. If tulips and hyacinths be examined, it will be found, that besides shedding seed, the bulb of the plant very often makes a smaller bulb on the larger one, and this, if taken off and planted by itself, becomes a new plant: many plants may be propagated in this way. The strawberry also, will be found to send off a long shoot, and, at about a foot distant from the parent root, a little knob appears, having a bud to spring into the air and a root to work into the ground: this is called a runner. These may be cut away from the parent and planted separately, and will become a new plant. Many other plants, such as roses, raspberries, and lilacs, send from their roots little thin stems: these are called suckers, and may be removed from the parent shrub and planted by themselves, when they will become separate plants. Many plants can be propagated by what are termed layers. To do this, nothing more is necessary than to select a shoot, as near the root as possible, and having partially divided it with a knife, make an upward slit in it, and then placing a bit of twig between the divided parts, press it down to the ground, burying the joint beneath the surface of the soil. To plant from cuttings, some care is necessary as regards green-house plants, but nothing is easier than to rear fresh stocks of roses, currants and gooseberries from cuttings, as it is only necessary to cut the shoots cleanly off, and, after reducing them to about six inches in length, to place them in the ground with the shooting end upwards. They should be planted about six inches apart, and after the first year be removed to their proper situation; and they will bear fruit in the following year. To plant from pipings, such as pinks and carnations, it is only necessary to pull off one of the tubular stems, and dividing it at or near the joint, pull off the surrounding leaves, and insert the end or jointed part in some fine sand-mould, placing a glass over them till they have "struck," that is, formed roots, when they can afterwards be transplanted.
