I08 FRUIT CULTURE UNDER GLASS. 



it had been three years planted, and planted it in another 

 vinery in which I had previously commenced the forcing 

 of pot-vines, and it ripened ten good bunches in May 

 1859. These instances are mentioned to show how 

 well vines bear being carefully transplanted or lifted. 



THE POT-CULTUEE OF GRAPES. 



Now that we-have such good keeping varieties of both 

 black and white grapes, that hang even till May, there 

 is perhaps less necessity for forcing pot-vines for the 

 supply of grapes in March and April than existed some 

 years ago ; still the production of grapes from pot- vines 

 is perhaps more extensively practised now than ever it 

 was. When certain varieties of grapes, such as Black 

 Hamburg and other early sorts, are required in the end 

 of March and April, I consider it better to produce 

 the first month's supply from pot-vines than to start 

 permanent vines in October and November to supply 

 them. The vines in most instances ultimately succumb 

 to the process ; whereas, if started a month or six weeks 

 later to succeed pot- vines, they are much more easily 

 kept in fair condition, and, moreover, produce better 

 crops. I have for many years regularly ripened a 

 crop of grapes from pots in AprU, and kept up the 

 supply by ripening a succession for May and June from 

 permanent vines, and consider this the best method to 

 adopt where early grapes are required. 



There are other cases where pot-vines supply grapes 

 in a most acceptable way, such as when vines and vine- 

 borders have to be renewed; in which case a vine in 

 pot can be fruited at intervals among the young vines, 

 without the one injuring the other. In cases where I
