Successful results in planting trees depend upon : 



(1) The trees. 



(2) Their proper protection. 



(3) Thorough cultivation. 



The trees must be fresh and vigorous, as well as carefully 

 selected with regard to the soil and climate of the locality in 

 which they are to be grown. Only transplanted evergreen 

 stock that is from fifteen to eighteen inches in height should be 

 used for permanent planting. Larger-sized evergreens for 

 ornamental planting can be handled successfully only when 

 balls of earth are bound securely about the roots. Broad- 

 leaved trees desired for street and yard planting should be 

 from eight to twelve feet in height, and from one and one- 

 fourth to two inches in diameter, though stock ranging from 

 four to six feet in height is better for extensive planting. 



The protection of planting stock is of prime importance be- 

 cause it is highly perishable, and suffers greatly from ex- 

 posure or drying. Planting should not be attempted during a 

 dry, windy period, and newly planted evergreens should always 

 be protected from the sun and wind. All young trees must be 

 protected against insects, rabbits, and live stock. Early spring 

 planting is preferable to fall or late spring planting. 



Thorough preparation of the planting site is essential to 

 good results. The soil should be very firmly tramped about the 

 roots of the newly set trees and thoroughly cultivated until the 

 trees are well established.
