Growing Sequoia (Redwood) from Seed: No Fire Required

Debunking the Fire Myth

While some conifers (like certain pines and Protea) require fire for cone opening or seed germination, coast redwood (Sequoia sempervirens) and giant sequoia (Sequoiadendron giganteum) do NOT need heat treatment. Their seeds germinate readily with standard stratification.

Simple Germination Protocol

1. Plant seeds 1/4 inch deep in moist (not soggy) potting mix
2. Maintain 60-70°F
3. Germination: 2-6 weeks (often erratic)
4. Prick out at 2-3 true leaf sets
5. Pot individually in deep containers (taproot!)

Stratification (If Needed)

Fresh seeds may not need it. Stored seeds benefit from 30-60 days cold (34-40°F) in moist medium.

Seedling Care

• Bright light (prevent etiolation)
• Consistent moisture—never dry out
• Half-strength fertilizer after true leaves
• Protect from frost first winter

Growing in Your Climate

Both species tolerate cold better than assumed. Dawn redwood (Metasequoia) is hardiest (Zone 4). Coast redwood to Zone 7. Provide summer moisture, good drainage, and space—these become massive trees!

Your Douglas Fir Success

18 inches in 3 years is excellent. Apply same care: patience, moisture, light. Redwoods grow faster once established.
