Comprising some 50 tree species from cool areas of the Northern Hemisphere, firs are used worldwide for lumber, pulpwood, Christmas trees, and ornamental plants. In parts of the North Temperate Zone these coniferous evergreens are dominant forest species, important for erosion control and wildlife forage and cover.
Most firs are medium to large, conical trees with a dominant central leader. Their flattened, straight or up-curved needles sit directly on the smooth branchlets (rather than on "pegs"), typically in two opposing rows. They usually have blunt tips and two white longitudinal under-stripes. The needles often have a pleasantly pungent, resinous odor. The branches occur in regularly spaced whorls of four or five. The bark is smooth and pale on young growth, but often thick and furrowed on older trunks and branches.
These wind-pollinated trees bear separate male and female cones on the same plant. The small, oval or cylindrical male cones hang from the undersides of the upper branches. They produce so much pollen you can see it in the air. The large, erect, seed-bearing female cones perch atop the upper branches. Their scales drop in autumn, shedding the winged seeds. The axis of the shattered cone remains on the plant.
Each fir is adapted to different areas, so choose the one that matches your climate and site. Generally, firs prefer full sun and neutral to slightly acidic soils with good drainage. Most perform best in areas with cool summers. Use firs in the landscape for as screens and specimens. (Source: learn2grow.com)

|Germination||A short period of cold and moist stratification (in the fridge) needed.|
1. Soak the seeds in clean water for 24 hours. Fully drain away all of the water and place the seeds in a zip-lock freezer bag. Place the seeds in the fridge. Make sure the seeds during this period not dry out or are waterlogged otherwise the pre-treatment will be ineffective.
2. After 6-8 weeks of the pretreatment seeds are ready to be sown.
3. Sow in a good quality potting compost. It shoudl be sterile and clean, never used before. Firm the compost gently, water and sow the seeds on the surface. Cover the seeds lightly (~2 mm) of vermiculite or sieved compost. Keep moist and at room temperature.
4. Germination will begin in a few weeks.
