Rocky Mountain Douglas-fir is a valuable timber tree. The wood is exceptionally strong and is used for structural timber as well as poles, plywood, pulp, dimensional lumber, railroad ties, mine timbers, log cabins, posts and poles, fencing, and firewood. Rocky Mountain Douglas-firs are also cut and sold as Christmas trees.
Douglas Fir grows best in full sun and prefers slightly acid, well-drained soil. Young trees are pyramidal, with branches that extend to the ground, so they make effective screens. But, as the years go by the bottom branches fall away.
In the landscape, large forms are best grown as specimens for large open spaces, while dwarf forms are suited to smaller garden spaces.

GERMINATION INSTRUCTIONS
1. Soak the seeds in a bowl of cool water for 24 hours.
2. 30-60 days cold moist stratification recommended for a higher germination rate.
Stratify seeds in a plastic bag full of moist sand inside the refrigerator for 30-60 days. Keep the sand barely moist during the cold stratification period.
3. Prepare a pot for each seed. Fill 20 cm (8") plastic pots with garden soil taken from the bed where the trees will eventually be planted. Sow one seed in each pot at a depth of 2-2.5 cm (1").
4. Water the seeds to a depth of 8 cm (3") after planting them. Maintain moisture during the germination process.
5. Place the pots outdoors in a sheltered spot where they will be exposed to direct sun in the morning and afternoon. Protect the seeds from direct sunlight during the hottest part of the day since the soil will warm too quickly and dry out.
6. Watch for sprouting one month after sowing. Maintain the same light and moisture conditions provided to the seeds during germination until they grow to 10 cm (4") in height.
7. Plant the seedlings into a sunny, sandy bed at least 75 days before the first frost in autumn, or shelter the seedlings in a cold frame until the following spring if it is too late in the year for planting. (info source: eHow.com)
