PRUNING 43 



growths and all sprouts from the stock as 

 they appear. As the plants age, worn-out 

 stems must be taken out and the centre left 

 open to encourage new shoots. Some of 

 these roses are short-lived and must eventually 

 be replaced. Hybrid Perpetual Roses of 

 weak habit e. g., Prince Camille de Rohan 

 should be cut back harder than vigorous 

 growers like General Jacqueminot, but only 

 when in good health. Hybrid Perpetuals, as a 

 rule, require the most severe pruning; Moss 

 and Provence Roses the least. 



2. Climb ing Roses the Dawson, Baltimore 

 Belle, Prairie Queen, Crimson Rambler and 

 others need not be pruned so hard as those 

 above described. Cut off in spring, before 

 the buds open, from one-fifth to one-third of 

 the previous year's growth; also, in estab- 

 lished plants, any of the old, flowering wood 

 which is enfeebled. Do not hesitate, even 

 if a part of the trellis is laid bare. It is by 

 this means only that these plants can be kept 

 vigorous. In summer take out most of the 

 old wood after it has finished flowering and 

 train new growths as desired, pinching out 

 weak and objectionable shoots.
