72 Fruitgrowing under Irrigation 



Thirdly. After trees have been left with their 

 terminals uncut for some years their vigour is 

 sometimes so severely checked through the mass of 

 wood they have to support and through the heavy 

 crops they have borne that but little new growth 

 is made. When this occurs the trees should be cut 

 severely back to stimulate new growth, which at 

 the following winter's pruning should be treated 

 according to its vigour if very strong again pruned 

 to the uncut terminal, and if moderate to weak, 

 shortened back. 



By varying the pruning of each variety according 

 to the vigour of the trees, pruning the weaker- 

 growing trees more severely than the stronger- 

 growing ones, balance is attained in both wood 

 growth and in fruiting, and the trees are kept 

 healthv and fruitful.
