CLIMBING SHRUBS 



and lanuginosa groups, etc., are often, unfortunately, very short-lived; 

 the greatest success with them has been obtained by growing them on 

 their own roots (not grafted on C. Vitalbd), and giving them a position 

 where the lower part of the stem is shielded from the direct rays of 

 the sun. 



The principles that govern the pruning of climbers on walls or 

 pergolas are the same as those that apply to ordinary shrubs, dealt with 

 in the chapter on PRUNING ($.v.\ The operation is regulated by two 

 considerations : viz., the space to be covered, and the time at which the 

 plants flower. As with shrubs in the open, climbers that flower on the 

 growths of the year (or those that flower so early in the season that the 

 ordinary period of growth is not thereby curtailed) should be pruned in 

 spring. Those that flower on the growths made the previous summer 

 should be renewed by laying in young wood and cutting out a proportion 

 of the old as soon as the flowers are past. Climbers on trees or wherever 

 space is unlimited need no pruning.

 be consulted in the body of this, work the list does not include ordinary 

 shrubs made to do duty as climbers on walls.
