THE TREE-MIGNONETTE.--This plant does not appear to be a distinct variety, for the common mignonette, properly trained becomes shrubby. It may be propagated by either seed or cuttings. When it has put forth four leaves or is about an inch high, take it from the bed and put it by itself into a moderate sized pot. As it advances in growth, carefully pick off all the side shoots, leaving the leaf at the base of each shoot to assist the growth of the plant. When it has reached a foot in height it will show flower. But every flower must be nipped off carefully. Support the stem with a stick to make it grow straight. Even when it has attained its proper height of two feet again cut off the bloom for a few days.
It is said that Miss Mitford, the admired authoress, was the first to discover that the common mignonette could be induced to adopt tree-like habits. The experiment has been tried in India, but it has sometimes failed from its being made at the wrong season. The seed should be sown at the end of the rains.
GRAFTING.--Take care to unite exactly the inner bark of the scion with the inner bark of the stock in order to facilitate the free course of the sap. Almost any scion will take to almost any sort of tree or plant provided there be a resemblance in their barks. The Chinese are fond of making fantastic experiments in grafting and sometimes succeed in the most heterogeneous combinations, such as grafting flowers upon fruit trees. Plants growing near each other can sometimes be grafted by the roots, or on the living root of a tree cut down another tree can be grafted. The scions are those shoots which united with the stock form the graft. It is desirable that the sap of the stock should be in brisk and healthy motion at the time of grafting. The graft should be surrounded with good stiff clay with a little horse or cow manure in it and a portion of cut hay. Mix the materials with a little water and then beat them up with a stick until the compound is quite ductile. When applied it may be bandaged with a cloth. The best season for grafting in India is the rains.
MANURE.--Almost any thing that rots quickly is a good manure. It is possible to manure too highly. A plant sometimes dies from too much richness of soil as well as from too barren a one.
WATERING.--Keep up a regular moisture, but do not deluge your plants until the roots rot. Avoid giving very cold water in the heat of the day or in the sunshine. Even in England some gardeners in a hot summer use luke-warm water for delicate plants. But do not in your fear of overwatering only wet the surface. The earth all round and below the root should be equally moist, and not one part wet and the other dry. If the plant requires but little water, water it seldom, but let the water reach all parts of the root equally when you water at all.
GATHERING AND PRESERVING FLOWERS.--Always use the knife, and prefer such as are coming into flower rather than such as are fully expanded. If possible gather from crowded plants, or parts of plants, so that every gathering may operate at the same time as a judicious pruning and thinning. Flowers may be preserved when gathered, by inserting their ends in winter, in moist earth, or moss; and may be freshened, when withered, by sprinkling them with water, and putting them in a close vessel, as under a bellglass, handglass, flowerpot or in a botanic box; if this will not do, sprinkle them with warm water heated to 80° or 90°, and cover them with a glass.--Loudon's Encyclopaedia of Gardening.
PIPING---is a mode of propagation by cuttings and is adopted in plants having joined tubular stems, as the dianthus tribe. When the shoot has nearly done growing (soon after its blossom has fallen) its extremity is to be separated at a part of the stem where it is hard and ripe. This is done by holding the root with one hand and with the other pulling the top part above the pair of leaves so as to separate it from the root part of the stem at the socket, formed by the axillae of the leaves, leaving the stem to remain with a tubular or pipe-looking termination. The piping is inserted in finely sifted earth to the depth of the first joint or pipe and its future management regulated on the same general principles as cuttings.--From the same.
BUDDING.--This is performed when the leaves of plants have grown to their full size and the bud is to be seen at the base of it. The relative nature of the bud and the stock is the same as in grafting. Make a slit in the bark of the stock, to reach from half an inch to an inch and a half down the stock, according to the size of the plant; then make another short slit across, that you may easily raise the bark from the wood, then take a very thin slice of the bark from the tree or plant to be budded, a little below a leaf, and bring the knife out a little above it, so that you remove the leaf and the bud at its base, with the little slice you have taken. You will perhaps have removed a small bit of the wood with the bark, which you must take carefully out with the sharp point of your knife and your thumb; then tuck the bark and bud under the bark of the stock which you carefully bind over, letting the bud come at the part where the slits cross each other. No part of the stock should be allowed to grow after it is budded, except a little shoot or so, above the bud, just to draw the sap past the bud.--Gleenny's Hand Book of Gardening.
