GROWING BUSH FRUITS 



Vigorous canes should be left per plant, but if the hedgerow 

 is used about ten canes to every 4 feet of row should be left 

 for fruiting. The amount of heading back depends upon the 

 vigor of the canes, the method of training or support, the 

 moisture-holding capacity of the soil, and the possible amount 

 of rainfall during the growing season. Usually the canes 



should be left 4 to 5 feet 

 high. The least amount of 

 heading that will result in 

 fruit of good size and still 

 keep the fruit off the ground 

 is desirable. 



A trellis is more gener- 

 ally used with red than with 

 black raspberries. If a trel- 

 lis is used, less heading back 

 is practiced and greater 

 yields are generally secured 

 (Fig. 227) . However, on ac- 

 count of the labor and ex- 

 pense of trellising, many 

 growers prefer to head back 

 the canes so they will be 

 stocky enough to stand erect

g^j^g the hill system is used, a 



stake or post is set at each 

 hill, and the canes are tied to it (Fig. 228). The system of 

 placing 3- or 4-foot posts at intervals of 20 to 30 feet and 

 stretching two wires along cross-arms is also used where the 

 narrow hedgerow or linear system is maintained. Other sys- 

 tems consist of using either one wire attached to posts as a 

 support for the vines or, in some cases, two or three wires
