![]() ![]() When the seedlings are a few inches tall, they can be transplanted.Seed will need to be cold stratified to ensure good germination. The seeds will begin to germinate in several weeks. 5g or 200-300 seeds Please note conifer seeds can be difficult to germinate successfully. Water the soil so that it is moist but not wet.Cover the seeds with a thin layer of soil about a couple of millimeters thick.Sow the seeds in containers with a good quality potting soil or compost. Tissue culture can also be used to propagate Douglas firs but the tissue taken must be from younger trees or seedlings. Put the bag in the refrigerator and leave it there for 4-6 weeks. Douglas Fir seedlings can handle almost any kind of soil or climate, and, ultimately, these trees become huge, incredibly tall, great-in-girth individuals, with. Douglas firs are normally propagated by seed this is because it is the easiest and cheapest method also it can be difficult to get cuttings to root.They can be planted outdoors in the fall or winter for spring germination or they can be cold stratified to simulate winter conditions and to break their dormancy at any time of the year. A good tree for northern and northwestern climates. Does best in locations with abundant air and soil moisture. Best grown in medium to wet, well-drained soils in full sun. This is one of the largest trees in the world. glauca is the commonly cultivated variety of this tree for areas outside of the Pacific Northwest, and is clearly a better selection for midwestern climates than the species because of its better cold tolerance (species is hardy to USDA Zone 6, but var. It grows at higher elevations (to 9500') with a slower growth rate, and has shorter cones (to 3"), blue-green needles and better winter hardiness. glauca is the Rocky Mountain variety of this tree. This is an important timber tree in the Pacific Northwest. Trees become more cylindrical with age as they lose their lower branching, with older trees typically having branching only on the top 1/3 of the tree. Narrow pyramidal shape with branching to the ground when young. Fallen or plucked needles leave raised circular leaf scars on the twigs. Flat, linear, spirally-arranged, dark green needles (to 1.5" long) with white banding beneath. Cones (to 4.5" long) are pendulous with protruding trident-shaped bracts. The species is indigenous to coastal areas and up to 5500' in elevation in the mountains from British Columbia south to central California. Unique forked cone bracts distinguish this tree from all other conifers. Pseudotsuga menziesii, commonly called Douglas fir, is a very large conifer that grows 50-80' tall in cultivation, but to 300+' tall in the wild. ![]()
