The Western White Pine favors deep porous soils with
medium acidity but will tolerate soils of poorer quality. Seedlings can
benefit from partial shade up to five years and full sun thereafter.
Growth can be very slow with seedlings started in nutrient-rich soil doing
best. Western white pines are generally drought intolerant.

Fusarium, a damping off disease, and neopeckia coulteri, a
snow mould are dangers for young seedlings. A root rot, rhizina undulata,
is also a problem in seedlings under 5 years. Birds and insects can also
kill young seedlings.
