PLANTING. 



The plants may be set out when two or three years old. Trans- 

 planting must be done very early in the spring, because the buds of 

 the tamarack start while other conifers are still dormant. The trees 

 should be set 6 feet apart each way. 



Tamarack may be grown in pure stands, but mixtures are advisable 

 with such species as balsam fir or spruce. When used for ornamental 

 purposes the tamarack should never be planted singly nor in exposed 

 places, for the branches are easily broken by wind and snow, and 

 exposure usually results in stunted or poorly formed trees. 



CULTIVATION AND CARE. 



The tamarack will rarely be planted where cultivation is possible 

 and the plantation will therefore require little care other than pro- 

 tection from fire and stock. Trees of this species should not be 

 allowed to become overtopped by their associates and deprived of 



light; 



In case of serious attack by the sawfly or other insects, specimens 

 should be sent to the Bureau of Entomology of the Department of 

 Agriculture for identification and suggestions as to control. Exten- 

 sive injuries from fungi should be reported to the Bureau of Plant 

 Industry of the same Department.
