Appendix 3. Guidelines for pruning white pine

Timing

Surveys indicate that older and larger trees are more likely to have stem cankers. Therefore, trees should be pruned as early as possible in order to maximize their probability of survival. Pruning is usually performed in two lifts. The first lift is for survival; subsequent lifts are for value although future survival is a consideration.

1st Lift

2nd Lift

A 3rd lift (to approximately 5.5 m) may be performed later to improve wood quality. A three-lift system is mainly recommended when white pine is used in reforesting a root disease area.

Standards

Refer to the Pruning Guidebook for more detail on proper pruning techniques.
