Gloire de Dijon remains, and is likely to remain, one of the most popular of garden Roses. It is not often seen at shows, because its flowers are imperfect from the exhibition standard. In this connection it may be well to mention that the system of pruning which is adopted has its influence. Gloire de Dijon is amenable to more than one mode of pruning. Broadly speaking, the long-rod system is the best where there is plenty of space, as giving the most flowers; but spur pruning may be resorted to with advantage where space is limited, and it will probably give the finest individual blooms.
A and D, Fig. 27, exemplify spur pruning. D shows a branch as it might be seen in spring trained to a wall, with its side shoots; A represents an individual side growth from such a branch. The result of shortening the side shoots in D to the black cross bars is to remove the greater portion of the lateral growth, and leave only short stumps of a few buds each, from which flowering shoots will break for another year's bloom.
It can hardly be said that this is the general way of treating Gloire de Dijon, because it is rare for the plants to be cut at all. The majority of people leave their plants altogether unpruned from year to year. It is probable, however, that of the cases in which pruning is practised the majority favour this system or its modification. B. When the main stem of a spur pruned tree gets very old or unhealthy, it may be cut right back to a dormant bud near the base in order to secure an entirely new break.
In E and F we see, in somewhat different degrees, the long-pruning system. The one is adapted for the open, pegging down the branches as shown at q, the other for a wall. The constant succession of young wood maintained by cutting out flowered branches, and taking up young ones which have started from buds near the base, undoubtedly tends to free flowering.
