shallow-rooted, so that this raking of fine old manure into the soil must be just that, and not the deep digging of half-rotted manure into the bed with a spading-fork. The aim in the method advocated is to put the solid manure where the spring rains will carry it in time to the feeding roots, and in the liquid form in which it is readily assimilated.

The theory of this manurial feeding will make clear the fact that a proper application of liquid manure has practically all the advantages of the former method without its drawbacks. For solid manure, if applied to the beds in quantities sufficient to be of real value, has a tendency to keep the needed air out of the top soil, and to bring in its train an abundance of weeds that will be hard to exterminate. So that, with the exception of light sandy soils, where the humus is needed, we shall do well to feed the rose garden liquid nourishment.

The time when this stimulant will be most effective is in the months of May and June, when most of the plants are putting all their efforts into the forming buds. Withhold the liquid in dry spells, for it is most appreciated immediately after a good, soaking rain.

Avoid getting the manure on the foliage, and make sure that it errs on the side of weakness rather than strength. Suspending a burlap sack containing a bushel of cow manure in a barrel of water for two days, will give a solution that needs dilution with its own bulk of water. A half-gallon to a plant each week will be a sufficient normal feeding.

Immediately after dosing the beds go over them with a rake or prong-hoe and loosen up the surface to prevent evaporation.

A vital principle in feeding rose plants is one that seems to be overlooked instinctively by seven out of ten amateur gardeners. It is this: A strong-growing, healthy plant needs and will absorb a large quantity of liquid manure; a sickly plant, or one that is not yet well established, does not need and cannot absorb even the normal quantity of this food. Yet how often are we tempted to feed to excess this weakling and withhold food from that nearby sturdy bush, because the latter "doesn't need it." Just bear in mind the fact that we do not give burgundy to a puny child that is struggling against the effects of malnutrition, but that a healthy, growing boy can consume an astonishing amount of food and drink.

To review the year's activities in fertilizing: let us put a top dressing of rough manure over the beds in the fall, about three inches deep, with further protection where the climate demands it. In the spring we shall rake off the coarse portion of this covering, leaving the finely pulverized manure to be raked gently into the top soil if it needs this additional humus (the manure's food value will have been washed down by the winter's rain and snow). If our soil is clayey the whole top dressing will be hoed off. In May and June come the generous applications of the liquid manure, and for the Teas and Perpetuals that really do continue to flower, these applications may well be continued through the summer at less frequent intervals, leaving off at the end of August, let us say, so as not to encourage unnecessarily the late summer's growth of wood.

Although not many of us, in all probability, will meet the unusual condition of having for our rose gardens only an over-fertilized soil in a long-used garden, it may be well to mention the fact that such a soil will not produce good roses. Treatment with lime will help matters for a time, but if within the range of possibility we should remake the garden with virgin soil.

The use of nitrate of soda and like stimulants may be undertaken sparingly in the spring, but these are better left to those gardeners who have learned, possibly through disastrous experiences, how properly to use them.

PRUNING

The rose is one of those plants that seem to need the firm hand of man to direct them in the way they should grow. If left to their own devices, most of the highly cultivated roses revert quickly to lower types; they need the pitiless pruning-knife to spur them to their best endeavor.

It will readily be seen that severe pruning, as a general principle, tends towards greater beauty of individual blooms, while light pruning is conducive to a better rounded-out form of bush at the expense of the flowers. Or, again, the severe pruning gives quality of bloom as opposed to quantity of bloom.

Always cut back the plants severely when first setting them out—Teas and Hybrid Teas less than the Hybrid Perpetuals, and the climbers least of all.

Unreasonable as it may seem, the plants of vigorous habit of growth need less pruning than the less active ones.

Pruning may be started with the dwarf Hybrid perpetuals in March—leaving four or five canes three feet in length if large masses of bloom are wanted. The result will be a large number of small flowers. If, on the other hand, fewer and larger flowers are wanted, all weak growth should be removed and every healthy cane retained and cut back in preparation for the plant's development. The weakest should not have more than four inches of wood left on the root, while the strongest may have eight or nine inches. Always prune a cane about a quarter of an inch above an outside bud unless the cane is very far from the vertical, when an inside one should be left for the terminal shoot. See that the wood is not torn or bruised in the operation.

The pruning of Hybrid Teas and Teas had better be postponed until the first signs of life appear. The bark becomes greener and the dormant buds begin to swell. Dead or dying wood will then readily be noticeable and it may be removed. Remember that these two classes do not need such severe pruning as do the Hybrid Perpetuals; twice the amount of wood may safely be left if it seems promising.

Dormant rose plants bought in the spring will arrive from the growers already partly pruned. In general, from one-half to two-thirds of the remaining length of cane should be cut off when the plants are set out, removing entirely all bruised or dead wood. Bear in mind always, if your conscience revolts at such severe cutting, that the strongest dormant buds are nearest the base of the plant and it is these we want to force into growth to bear the prize blooms.

With the ramblers very little cutting is needed; merely cut back the shoots that seem to be outdistancing their neighbors by too much, and cut out entirely the dead canes.

The rugosa is intended to be a bush rather than a strong, lean plant for prize blooms. Merely cut out old, dry wood and trim back the longer shoots to the desired form.

Use a first-class pair of pruning shears in order that the work may be done quickly and, above all, with clean cuts that show no tearing or abrasion of the bark.

PESTS

Once more let me repeat the fact that by far the most effective campaign against the insects and other pests that infest rose plants is to be found, not in sprayings and dustings, but rather in maintaining to the best of our ability a condition of health in the plant itself. Prevention here, as always, is better than cure. Nor can it be too strongly emphasized that the daily use of a powerful but finely divided spray from the hose will make life on the rose plant miserable for practically all of the parasites.

The following are the chief enemies that we may encounter in the rose garden. They are briefly described so as to be recognizable when found, and for the annihilation or keeping in check of each is given one of the many remedies. Practically every rosarian develops, after a time, his own pet formulæ for these poisons, so that rose books will be found to contain a wonderfully varied assortment of weapons—so numerous in fact that one would think the army of rose pests could never live to continue their depredations another season.
