Douglas-Fir Seedling Grows 8 Feet Tall in Two Seasons
A 96-inch-tall coastal Douglas-fir (Pseudotsuga menziesii [Mirb.]Franco) seedling was grown from seed in two years. Greenhouse temperatures of 60° to 70° F, a six-month growing season, long day, adequate winter chilling, large pots, periodic fertilization, and frequent watering are thought to be contributors to the rapid growth.
