Generally about the end of the month the very severe frosts are over; and when none need be apprehended that would materially injure hardy shrubs, they may freely be pruned of all dead branches, and the points cut off such shoots as have been damaged by the winter. Most of shrubs require nothing more than to be pruned of straggling, irregular, and injured branches, or of suckers that rise round the root, observing that they do not intermingle with each other. Never trim them up in a formal manner. Regular shearing of shrubs and topiary work have been expelled as unworthy of a taste the least improved by reflections on the beauty, simplicity, and grandeur of nature. In fact, the pruning of deciduous hardy shrubs should be done in such a manner as not to be observable when the plants are covered with verdure. It may frequently be observed in Flower-gardens, that roses and shrubs of every description are indiscriminately cut with the shears, the Amórphas and Althèas sharing the same fate.

Robínias, Colùteas, Cyticus, Rhús, Genístas, with several of the Viburnums, and many others, bear their flowers on the wood of last year, and when thus sheared afford no gratification in flowering. And those shrubs that thus flower on the shoots of last year are perhaps worse to keep in regular order, than those to which the knife can be freely applied; but good management while young will ensure handsome free flowering plants.

Climbing shrubs, and others that are trained against outbuildings, walls, or such as are sheltered thereby, and not now in danger of suffering by frost, may be pruned and dressed. These should be neatly trimmed, and the branches moderately thinned out, tying in all the shoots straight and regular. Avoid at all times, if possible, the crossing of any shoots.

There is not a shrub in the garden that agrees so well with close cutting, as the Althèa, and all its varieties. These can be made either bushes or trees, and kept at any desired height. Where the wood of last year is cut to about two or three inches from the wood of the former year, the young shoots of this year will produce the largest and finest flowers, and likewise more profusely. When they have attained the desired height, let them be kept in the most natural and handsome shape that the taste of the operator can suggest. They will bear cutting to any degree.

Honeysuckles of every description may with all freedom be trimmed, providing the frost is not very severe. These are very frequently allowed to become too crowded with wood, and then superficially sheared or cut. The flowers would be much finer, and the bush handsomer, if they were regularly thinned out, divesting them of all naked and superfluous shoots. Of those that remain, shorten the shoots of last year. Where any of the honeysuckle kind has become naked at the bottom, and flowering only at the top of the trellis, or extremities of the shoots, one half of the bush should be cut to within four inches of the ground. It will throw out plenty of fine young wood, which give room for, and train them straight, and to the full extent, during summer. These shoots will flower profusely the following season, and in like manner, when thought proper, the other half can be cut.

Roses of the hardy kinds (termed garden roses) that were not attended to in November, should, if the weather permit, be dressed and pruned forthwith. In small gardens, where these are generally attached to the walls and fences, neatness should be a very particular object. If any of such bushes have got strong and irregular, the most proper method to bring them to order, will be to cut down each alternate shoot of the bush to within a few inches of the surface, thereby renovating it, and, in part, preserving the flowers. Those that are cut down will put out several luxuriant shoots, which must be regularly tacked in, spreading them in a fan shape. These, in another year, will flower well, when the others may go through the same operation. Thus, in two or three years, the bushes will have resumed a different, and more agreeable aspect. By the above treatment, these ornaments of the garden will always have a neat and healthful appearance, and the roses will be much finer. Where they are intended for the borders, they should never be allowed to get too high. In a border from four to six feet, they ought never to exceed four feet at the back of the border, and in front, one foot, after being pruned; they can be kept down by the above method. It is not advisable to cut down rose bushes all at once, unless no regard is paid to flowering. The roses that are in grass plats would have a superior appearance in every respect, if they were kept and trimmed like small trees. They may be of different sizes and heights, according to the extent of the grass plat or clump. A single stem may arise from six inches to six feet, with a head in proportion to the height of the stem. Where it is necessary to have them above two feet, and likewise to carry a good head, inoculation must be resorted to, which, in the months of June and July, will be fully treated of. All under two feet (except the weak growing kinds) will do on their own stems, taking care not to allow shoots to arise from the bottom during the summer.
