Growing directions
Plant rooted cuttings or container-grown trees in spring in well-drained, slightly acidic, deep, moisture-retentive, fertile loamy soil in full sun to partial shade; coast redwood is the world's tallest living tree — the tallest known individual (Hyperion in Redwood National Park) reaches 380 feet. Native to the fog belt of the California and Oregon coast, coast redwood is uniquely adapted to harvest water from fog directly through its needles, supplementing root-absorbed water in the dry California summer. Remarkably fast-growing for such a large tree — growth of 3–5 feet per year is common in ideal conditions in zones 8–10. Distinct from giant sequoia in being taller but much slimmer, with flat needles arranged in two ranks (like yew), and in its ability to sprout vigorously from the base after cutting or fire. Widely planted in California, the Pacific Northwest, and milder parts of the world (Ireland, New Zealand, the UK). Cutting-propagated plants from named selections are more reliable for garden planting than seed-grown trees.
