Siberian Spruce (Picea obovata) is a spruce native to Siberia, from the Ural Mountains east to Magadan Oblast, and from the arctic tree line south to the Altay Mountains in northwestern Mongolia.
It is an important timber tree in Russia, the wood being used for general construction and paper making. The leaves are used to make spruce beer. (info source: wikipedia.org)
Likes abundant moisture at the roots, if grown in drier areas it must be given a deep moist soil. Succeeds in most soils including those that are wet cold and shallow, but it is not very wind-firm in shallow soils. Intolerant of chalky or poor acid soils. Tolerates poor peaty soil. Intolerant of atmospheric pollution. Resists wind exposure to some degree and is tolerant of saline winds. A very cold-hardy tree when fully dormant, though the young shoots are subject to injury by late frosts.

| Germination | 1. Soak the seeds in room temperature water overnight. 2. Keep the seeds in refrigerated, soil-filled zip-lock bags for 2-3 months after the initial soaking, a process that mimics the natural dormancy period they would experience during winter months in the wild. Some experts recommend this method, and others say seeds may be planted immediately after soaking. If soaked seeds are not kept in soil, they may be refrigerated for up to 14 days before use. 3. Place a 3-inch layer of dry soil, such as peat moss or clean sand, in a small vase. Bury spruce seeds 1/4-inch below soil. Cover soil with mulch layer. Keep the vase in a partially shaded place. Water occasionally, so that the soil is always slightly moist. 4. Seed will sprout in three to eight weeks. For one year, keep seedling in partially shaded place. Water occasionally, so that the soil is slightly moist. 5. After one year, transfer the seedling to a gallon-sized vase or larger, maintaining a balance of dry, clean soil and mulch. The seedling may now be kept in full sun. Continue watering occasionally, so that soil is slightly moist. (info source: eHow.com) |
