DISTANCE APART FOR PLANTING

good enough to prevent a loss of more than 153. an acre 

 being incurred. For the loss will be refunded by the saving 

 effected by planting younger plants. 



As a general rule, I and 2 year seedling plants should not 

 be planted farther apart than 2 feet 6 inches to 2 feet 9 inches 

 that is, 7000 to 5800 plants per acre. 



For the extra expense of planting the large number of 

 seedling trees is not very great ; and it is always most 

 essential to obtain a close canopy as soon as possible ; and 

 the necessity for filling up blanks is largely avoided. The 

 actual distance apart at which trees should be planted, 

 depends chiefly upon the persistency of the side branches 

 and the vigour of each year's growth. The side branches 

 must be naturally killed before they are too big to readily 

 drop off; in other words, the trees must be planted so close 

 that large side branches can never develop. 



The maximum distance apart at which trees three to four 

 years old should be planted in even-aged high forest is as 

 follows : 



5 feet apart 



4 feet apart

 growth. Only a very small proportion of Oak trees originally planted, 

 are ever worth leaving when 40 years of age.
