Part 4

Top soil from an old pasture, if it be a moderately heavy loam, taken with the grass roots and chopped very fine, will do excellently for the Hybrid Perpetuals. For the Teas and Hybrid Teas, mix with soil of this kind about one-quarter of its bulk of sand and leaf mold to lighten it. Remember that all the manure that is used should be incorporated with the lower two-thirds of the bed; the upper third should not contain any recently added manure as it is apt to harm the roots of new plants.

PREPARATION AND PLANTING

In the vicinity of New York and further north, I think it will be found that spring planting is best. South of Philadelphia many roses are set out in the fall, for here they become well established before cold weather sets in, and are therefore ready to start active growth at the first touch of spring.

If spring planting is chosen the plants must be put in the ground early--at the very first opportunity--so that they will have time to become firmly established before hot weather. Pot-grown plants from a greenhouse cannot, of course, be set out until all danger from frost is past. Roses that are planted so late cannot be expected to show really satisfying results in bloom the first year. Roses that are planted early in the spring, if field-grown stock as explained below, will with proper cultivation give at least a reasonable amount of bloom the first year, though not so much as in later years.

One hears a great deal of argument on the question of whether roses are best grown on their own roots or when grown on a sturdier stock, such as Manetti for Hybrid Perpetuals and brier for Hybrid Teas, which are probably the best rose stocks for this country. It seems to be the general consensus of opinion that roses budded on these stocks will thrive much more luxuriantly and give much better blooms than those which depend upon their own root systems. It is necessary, however, to set the point at which the shoot is budded to the stock about two inches beneath the surface; otherwise there is the constant danger that suckers will spring from the root and, if overlooked for a time, these will kill the more desirable shoots.

Several kinds of roses are offered by the dealers for setting out in the spring. There are the pot-grown roses mentioned above--the only form in which many of the climbers may be readily obtained. Mail-order houses make a practice of sending out the Hybrid Perpetuals, Hybrid Teas and Teas also in this form of very young plants grown from cuttings under glass during the winter. Costing more, and surely far more dependable, are the field-grown roses that have originally been budded on Manetti or brier and, usually in two-year-old form, taken out of the ground the previous fall while dormant, to lie in cold houses until ready for planting. Such roses as these will surely bloom the first season and are far better equipped for the shock of being set into the open ground again than the pot-grown plants that have never had a taste of real garden life.

A word of warning might profitably be uttered against the cheap roses budded on multiflora stock, grown in Holland and sold in some of the department stores. They are short-lived and very poor in comparison with plants on brier and Manetti. Multiflora has been entirely discarded as a stock by English and Irish growers.

Roses on their own roots have the advantage of being cheaper, due to the saving of labor in striking cuttings rather than budding--one-year-old plants costing a dollar for six to a dozen; two-year and three-year-old bushes, which are, of course, far more desirable, cost more in proportion. Dormant, field-grown budded roses cost, in the two-year-old size, from thirty-five cents to a dollar each.

Before setting the plants examine each carefully and cut off the broken roots with a sharp knife, as well as all eyes that may appear on the root stock, in order to forestall suckers. The plants should be set immediately upon their receipt from the nurseryman, so that they will not become dried out. If they seem dry it may be well to puddle the roots in thin mud just before setting. Make the hole large enough to accommodate all of the plant's roots without crowding, remembering to put the budding point not less or more than two inches below the surface and with the roots spread out nearly horizontally, but inclining downward towards their ends and without crossing one another. This will not be an easy matter, for in shipment the roots will have probably been so compressed that they extend almost directly downward from the collar. After the plants have been firmly set and the earth carefully packed in around the roots, rake the soil to loosen it up over the whole surface. The soil will probably be moist enough at the time to need no watering.

With the pot-grown plants, the moist ball of earth that comes about the roots is carefully retained intact and placed in the hole prepared for the plant. Set the plant firmly in place by pressure with the soles of your shoes, give a generous watering and finally break up the surface of the soil with a rake.

It is absolutely essential to keep the surface of the ground loosened with a hoe and a sharp steel rake throughout the summer. After very hard rain loosen the soil as soon as it is dry enough to work, to conserve the moisture.

FERTILIZING

In striking contrast to the exquisite beauty of the rose is the food that we must give it in abundance if we would have the most healthy plants. But for the true rose enthusiast the turning over of a muck heap to find manure in just the right form, or the dilution of the by-products of the cow barn with water to make the best stimulant, have nothing about them that is in the least objectionable.

If the soil at our disposal is inclined to be rich in clay, we can probably do no better than incorporate well-decomposed stable manure with it, by raking it, well pulverized, into the surface in the early spring. In sandy or gravelly soils, however, cow manure or that from the pigsty will serve far better. It must be remembered that when properly set out the rose plant is comparatively 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.
