As to the time of planting, early November is the best of all. However, rose planting may be carried out successfully from the middle of October until the end of March or early April, but not later when the plants are from the open ground. Roses from pots may be planted at any time of the year, though preferably not later than May, since the roots are not disturbed and the plant receives no check. If the removal is carefully carried out one may shift even large roses from one part of one's garden to another without their suffering, providing they are transplanted, say, not later than the first week in November. When bought plants are put in, severe pruning is invariably necessary the following spring.
Some growers advise covering the rose beds with manure in autumn when planting is finished.
Others, and I am among. I give a coating of farmyard manure 'as soon as pruning is finished, which is usually about the first week in April. This is forked just beneath the surface. The roses receive no further manure, except occasional dressings of fertilizer during summer. Tonks' manure is especially beneficial to roses.
