Problems that you can
help white pine overcome

Whether you find them already growing on your land or you plant them, white pines benefit from forest management. White pines need to be planted where they can avoid diseases and insects and be protected from deer browse and plant competition. White pine seedlings can not be "stuck" in the ground and forgotten.

White pine blister rust is a fungal disease that infects needles but spreads into the branches and stem where it causes branch death, topkill, stem cankers and can be fatal. It is an exotic disease, first found in Minnesota in 1916. The major problem with this disease is that it kills white pine seedlings and saplings in certain climates and topographies.

White-tailed deer like to feed on white pine seedlings and saplings which stunts or kills them. Deer chew off twig tips, particularly the buds on the growing tip (terminal leader).

White pine weevils are insects that cause the wilting and death of the tree's leader (or terminal) in June or July. At least two years' height growth can be lost in a single attack and the damage usually causes forking of the stem. Repeated attacks cause the tree to become bushy and stunted.

Weeds, grasses and shrubs compete for light, water, nutrients and space with the white pine seedlings. Seedlings can grow slowly, be stunted or die from competition.
