PLANTING 31 



two varieties, as two sorts of apples, or two sorts 

 of pears, both of one kind of fruit placed together. 

 In practically all cases there will be one-fourth per- 

 manent trees and three-fourths temporary trees. 

 The temporary trees should be smaller in habit of 

 growth and earlier in habit of bearing. 



In the second type of interplanting, two different 

 species or kinds of fruit are used ; usually permanent 

 apple trees are interplanted with peach or plum, 

 sometimes with pear, or cherry trees. 



The third type consists of a still further filling of 

 the orchard, in which three different types of fruit 

 are used. Such a plantation consists of (i) perma- 

 nent apple trees, (2) temporary fillers, such as pear 

 or cherry, and (3) underplanted rows of bush 

 fruits, such as currants or gooseberries. Such 

 triple-planted plantations are not uncommon nor 

 always unsuccessful. Strong soils, high feeding, 

 and constant attention are required to get good re- 

 sults from such a complicated arrangement. 



The advantages of these double-planting and in- 

 terplanting methods are emphatic. Space is greatly 

 economized, and as fruit land is often very high 

 priced, this economy means a good deal in cash. 

 Fertilizer is also economized to a greater or less ex- 

 tent. The expenses of cultivation, etc., are also 

 proportionately reduced. Another advantage of 

 considerable importance in many cases is that the 

 interplanted trees and bush fruits come into bearing 

 earlier than the permanent trees and put the plan- 

 tation on a remunerative basis much sooner. 



There are disadvantages, of course: thickly 

 planted plantations are difficult to manage, difficult 

 to cultivate, and especially difficult of access with 

 spraying machinery. They require much more
