digging and should be so handled until permanently planted that the 

 buds cannot start. Plants in leaf should be moved with a "ball of 

 earth." In most deciduous fruits aeration of soil is necessary for 

 absorption and continued submergence leads to the death of root hairs 

 and roots. Plants developing in the spring under circumstances such 

 that they have large water requirements, . continue to demand large 

 amounts throughout the season and cultural operations should be shaped 

 accordingly. Summer pruning may reduce water requirements some- 

 what, but the reduction is not proportional to the loss of foliage. Some 

 protection against water loss may be afforded by windbreaks and the 

 choice of northern slopes.
