As one who has done some study on these beauties, I will say this is not quite right. If the temp gets low enough, fog moving thru Coastal Redwoods, Sequoia sempervirens (rarely are they referred to down here as 'sequoias"...that is usually used for the Sierra redwoods, Sequoiadendron giganteum, such as in Sequoia National Park) the moisture from the fog gathers on the leaves and drips down to the ground, thus providing moisture for the trees during the periods of little rain in the summers. No moisture is drawn in by the leaves, but of course the fog reduces the transpiration rate and helps keep what moisture in the leaves in the leaves.

While attending university in New Zealand, I would visit the five redwoods in the botanical park in Christchurch about every week (there was one on campus, too). They gave up trying to grow them commercially...they grew too fast, making the wood too weak for structural uses.
