22 THE FORCING GARDEN. 



get both sun and air and moisture as they require it. 

 Then the ' protector ' will form the desideratum for 

 regulating the superfluous moisture during the winter, 

 and possesses the advantage that it can be removed 

 when the spring comes, so that the roots can get all 

 the benefits arising from the full play of all three 

 elements. Here then can be seen the difference 

 between planting vines inside the house and pre- 

 venting the roots getting outside by walls. I have 

 known several failures of young vineries caused solely 

 through this, and where they do not immediately fail, 

 it is by reason of a great deal of labour in watering 

 and artificial manure, or else failure would prove in- 

 evitable. Those who intend planting vineries for 

 forcing houses should plant them inside the houses, or 

 rather, let the stems be inside of the front wall and the 

 roots outside. This is easily done by small arches 

 turned in the front wall under the surface of the bed 

 outside. 



WINTER PRUNING- THE VINE. 



The manner of pruning the vine depends chiefly 

 upon the constitution of the plant. Some prune on 

 the long-spur and some upon the short-spur, whilst 

 others do so on the long-rod plan, and each of these 

 may be equally good. The long-rod pruning can only 

 be adopted when the vines are very strong, and it 

 is known that this method can be safely employed 

 annually without deterioration, or ultimately causing 

 a failure of the vines. 



Either of the two former methods may be adopted 

 annually, and some experienced gardeners always 

 prune on the short-spur and get good crops, while
