The Sierra Redwood obviously does better in lime soil, even at unnaturally low altitudes which are the home of Coast Redwoods.
All over England Sequoiadendron giganteum from high altitudes (8000 ft +) in the Sierra Nevada Mountains of California thrive in lime soil in the gardens of stately homes and in churchyards. But Sequoia sempervirens Redwoods originating from low altitudes along the coast of California barely survive. Here we can see the two growing side by side.
I might add that the Sierra Redwood is the tall one on the left and the scraggly looking one on the right is the Coast Redwood. In California, though, the Coast Redwood grows by far the taller.
The reason seems to be that the Coast Redwood does not like alkaline soil. Compare this sad tree on the right with Michael Hatton's picture of some old-growth Coast Redwoods in Northern California: www.panoramio.com/photo/2020909
