 the Sweetbriers, R. setigera, the type, and the 

 Dog Rose, are commonly grown as bushes and

 keeping the centres open; but the flowering 

 wood must not be removed after blooming

Trailing Roses (R. Wichuraiana and its 

 varieties) require comparatively little pruning, 

 particularly in the North, where unfavourable 

 seasons are apt to kill some of the wood. By 

 taking out dead branches and cutting back

 to keep them in good condition. 



Half-climbing hybrids of this rose — e. g., 

 Sweetheart, Debutante, etc., and the old
