Calocedrus decurrens, or Incense Cedar, is an evergreen tree native to the mountains of southern Oregon, California and western Nevada. Mature trees can grow in full sun, but young trees benefit from afternoon shade. You can expect your trees to reach 75'-90' at maturity and have a dense, narrow, almost pyramidal crown. Incense Cedars are slow to establish, but will grow about 2' per year once established. Plant your new trees in ordinary garden soil by digging holes large enough to accommodate the root systems without cramping. Place a small mound of soil in the bottom of the hole and drape the roots over it, then allow the rest of the roots to spread out naturally. Backfill with soil, gently tamping to remove air pockets, and water well. Ultimately, your trees should be at the same level in their new homes as they were growing before you transplanted them. Plan to regularly water each tree during the growing season for the first 4-5 years. After that time the trees should get along on natural rainfall. Your trees won't require fertilizing. In fact, overfertilizing cedars can result in rank growth that is weak. Cedars grow slowly, becoming dense and symmetrical at maturity.
