How do coast redwoods grow so tall?
Coast redwood is an evergreen conifer capable of becoming one of the world's tallest trees in a suitable humid coastal climate.
Structure, development and life cycle
Rapid wood production, a long growing season, high rainfall and summer fog support great height. Leaves can capture fog water and aid crown water balance. Thick fibrous bark offers some heat resistance, and dormant buds allow sprouting from trunk or root crown. Moving water from roots to the top is a major physical limit on height.
Growing, uses and cautions
A young natural forest is not equivalent to an old-growth forest with centuries of structure. Conservation includes deadwood, streams, fog climate and connected habitat as well as large trees. Garden planting must account for enormous mature size, root space and water needs. Climate change can alter fog and drought patterns and therefore growth.
