Douglas Fir plant profile

Pseudotsuga menziesii

A perennial tree for full sun.

Last updated .

When to plant Douglas Fir

Plant this conifer in early spring, before new growth begins, or in early fall. Extension guidance rates those two windows as best because roots can establish before summer heat or a hard freeze; container or balled-and-burlapped stock goes in during these cooler, low-stress periods.

The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
