The management of perennial crops differs from that 

 of other' vegetable-gardening crops in the fact that they 

 are more or less permanent occupants of the ground, and 

 therefore must be given an area to themselves where they 

 ivill not interfere with the customary plowing and tilling; 

 in the fact that the chief tillage and care are required early 

 and late in the season; and also because the fertilizing is 

 secured {after the initial preparation of the land) chiefly 

 by surface dressings in spring and autumn. It is advisable, 

 therefore, for cultural reasons, to place these vegetables 

 in a group by themselves, although otherwise they have 

 little in common. 



The reader must distinguish between perennial crops 

 and perennial plants. Many perennial plants are treated 

 as annuals in cultivation, as tomato, red pepper, potato, 

 scarlet runner bean, horse-radish, dandelion. On the 

 other hand, some of the perennial crops profit by frequent 

 renewal, as the artichoke. But while the demarca- 

 tion is indefinite, the gardener readily understands it.
