Four things are absolutely essential in high rose culture - a rich and deep soil, judicious pruning, freedom from insects, and watering when requisite. If any one of these be wrong, the success will be in proportion incomplete. Soil is the first consideration; what is termed a sound loam, they all delight in; the soil should be adapted to the stock rather than the scion, or kind worked on it. The common, or dog-rose stock thrives best on strong loamy soil, in half-shaded situations near water, without manure; cultivated roses require the latter because they have more hard work to do; their amount of blossom,, if weight alone be allowed as a test, would, in most cases, doubly and trebly exceed that of the dog-rose - added to which they have less foliage.

Roses, on their own roots, require that the soil be modified according to kind; we should not use so adhesive a soil to a Tea or Bourbon rose as to ordinary kinds; organic matter is here required. Depth of soil is of great importance to all kinds; it is the deeper series of fibres, situated in a proper medium, that sustains a good succession of flowers, in defiance of heat and drought.

Judicious pruning reduces the rampant growths, and increases the energies of those which are of a more delicate constitution, relieves from superfluous shoots and useless wood, and reduces the whole outline to a compact or consistent form. Insect ravages must be guarded against - tobacco water or fumes will do this; bathing them twice a day with water from a barrow-engine is only objectionable from the time required. If you have not provided deep culture, watering, in dry times, will be requisite; but this should be done thoroughly rather than frequently, and the surface soil should be frequently stirred without injuring the roots. Liquid manure - say two ounces of guano to a gallon of water - should be given once a week. With this treatment, every one may have fine roses.
