84 FRUIT CULTURE UNDER GLASS. 



single leaf, as is sometimes practised. The whole of 

 the roof should be furnished, but not crowded, with 

 foliage, and the pinching and tying of the lateral 

 growths regulated with this end in view. In propor- 

 tion to the extent of foliage will be the extent of the 

 roots formed in the border. This treatment of course 

 applies to the permanent vines, from which no fruit is 

 to be taken the following year ; and all the growth 

 and expansion that the roof affords them without 

 shading the temporary vines should be allowed them. 

 When they reach the top of the house they may be 

 trained down the back wall. In the case of those 

 planted with the intention of their bearing a crop, of 

 fruit the following year, a more restricted growth is 

 desirable. The laterals should be regularly stopped 

 when they form two leaves, and the leading shoots 

 stopped when they reach little more than half-way 

 up the roof; and those planted for cropping the upper 

 portion of the house should be stopped when they 

 reach past the top wire. These being restricted, and 

 their energies, so to speak, concentrated, they form 

 better-developed buds on the main stems, from which 

 the crop of next season is produced. Care, however, 

 must be exercised in stopping with the same pertina- 

 city after the leader is stopped, for there is a danger 

 of the main buds bursting if the laterals are then too 

 closely pinched ; so that it is better to allow them to 

 grow more for a time near the top, where some few of 

 the main buds generally push after the stopping ; and 

 these, too, should be allowed to grow a little till the 

 stem gets firmer, and there is no danger of the buds 

 bursting lower down. 



Watering must be attended to after the vines have 

 started into rapid growth, and sufficient applied at
