Adopt a Redwood

By planting 10,000 Redwood trees in the San Francisco Bay Area, together we will build powerful carbon sinks to fight climate change.

Our team grows Sequoia sempervirens from seeds in West Marin County, California. Staff and volunteers collect cones locally and bring them back to our native plant nursery for processing and stratification; afterwards, the seeds are ready for germination. Redwood seeds are planted at high density due to low germination rate (a mature tree can produce up to 100,000 seeds per year, but approximately only 1 in 12 seeds are viable). Once germination has occurred, seedlings are always kept moist, shaded and at a temperature range of 45-70 degrees F. Approximately three to four months after germination, seedlings will be transplanted into a tree pot that allows for long roots to form. The seedling will grow and develop a long root system for two to three years in our nursery before being planted out into land. When the Redwood is ready for planting, we place it in a space that is appropriate for a seedling to develop into a mature tree.

After growing the base of its root system, a healthy Redwood will grow 5 to 6 feet each year and can easily reach 150 feet within a person’s lifetime.
