Hybrid Bourbons.—Prune the laterals lightly, and leave the best of the base shoots.
Hybrid Noisettes and Musks.—Thin out old wood and tie in young shoots.
Austrian Briars.—Only cut out dead wood. Soleil d'Or, a hybrid, flowers on the young wood, and the shoots may be pruned back to two feet.
Scotch Briars.—No pruning is needed, except cutting out old and dead wood and shortening back some of the numerous suckers.
Climbing Multifloras need little pruning. When grown as pillars or on screens they are apt to get bare at the base. Therefore it is well to cut some of the weaker young shoots back to two or three feet to clothe the base, leaving the strong ones their full length. With Crimson Rambler and its class, cut out some of the old wood to make room for the young shoots and shorten any weak laterals: but leave most of the strong ones intact, and do not touch the long base shoots of the last year.
Wichuraianas.—Only cut out old and dead wood. I have seen a beautiful effect produced with Dorothy Perkins by cutting out all the old wood in the autumn, and training the long young shoots over wire frames two-and-a-half feet wide, forming low arches about a yard from the ground in the centre. The mass of flower shoots standing erect on these frames makes a most strikingly beautiful object. The Wichuraianas also form very lovely weeping standards on eight-feet stems. And for tall pillars and fountain roses they are unequalled.
Chinas.—The old Blush and Cramoisie Supérieure should only be thinned. The newer kinds, such as Mme. Eugène Resal, [Laurette Messimy], etc., may be cut back to a few eyes from the ground.
Bourbons.—Prune lightly, growing as bold bushes or standards; except Hermosa, which may be pruned back to form a dwarf, spreading, two-feet bush; while Mrs. Bosanquet is treated like the Chinas.
Noisettes are of two types. The strong growers need hardly any pruning, except Maréchal Niel, which must have all cankered and weak shoots removed after it has flowered. Lamarque, Fortune's Yellow (which must not be pruned at all), and Jaune Desprez need a wall; and Céline Forestier prefers one.
The other type, such as L'Idéal and [William Allen Richardson], may be pruned fairly close, by cutting back the laterals to a few eyes. All Noisettes bear their flowers on the laterals; therefore these should be preserved as much as possible.
