material can supply. Some of them possess most beautifully 

 cut or shaded foliage, while others produce most beautiful 

 flowers, and when once planted they grow on for many years 

 with but little care. Some of them, like the wistaria, 

 aristolochia, aclinidia, bitter-sw^eet, etc., will twine about 

 large pillars or other supports, some will support themselves 

 on brick or stone walls by their sucker-like tendrils, while 

 many, like the clematis, etc., require the support of the 

 trellis, the single wire, or the wire netting. 



If grown too abundantly or trained too closely to the 

 building, vines often render the dwelling damp and unhealth- 

 ful and cause rapid decay of the woodwork. 



As to cultivation, they require the same care and fertility 

 of soil as recommended for upright shrubs. Fig. 52 shows 

 a vine-covered cottage in June. 



PRUNING CLIMBERS 



In addition to the pruning required to keep climbing 

 vines within proper limits, which can be done largely by 

 pinching and light clipping during the summer, they require 

 in some cases the cutting back of the old wood of the laterals 

 in order to produce fresh clean shoots and foliage, and in 

 other cases the heading in of the young wood to encourage 

 development of the blossom-buds. In a few cases as with 

 roses winter protection should be provided by tying straw 

 around them or covering them with loosely tied matting. 

 Any covering of this kind, however, unless very neatly 

 done, detracts from the appearance of a veranda or arbor 

 and should be avoided if possible.
