How to Grow Dawn Redwood Trees from Seeds: A Beginner's Quickstart
A first-time grower's plain-language guide to germinating a living fossil
Last Updated: May 13, 2026
The seeds are tiny, papery, and surprisingly forgiving once you understand what they need.
Dawn redwoods (Metasequoia glyptostroboides) are sometimes called living fossils, and for good reason. The species walked the earth alongside the dinosaurs, was thought extinct for millions of years, and was rediscovered alive in a valley in central China in 1944. Every dawn redwood growing in the world today comes from that one small grove. Growing one from seed is a quietly extraordinary project, and the good news is that it does not require a horticulture degree.
Before we get into the steps, one honest expectation. Dawn redwood seeds germinate at a low rate, somewhere between 5 and 35 percent depending on the batch. That is not a defect. It is how the species reproduces. The fix is simple: plant more seeds than you think you need. If you sow 20, expect 1 to 7 seedlings. That is a successful result. We have explained the science behind our methods in detail elsewhere, but the short version is that living soil and patience do most of the work.1
What You'll Need
- Fresh dawn redwood seeds (plan on sowing 15 to 20 to account for variable germination)
- Room-temperature filtered or dechlorinated water
- A small container or zip bag
- A paper towel or a pinch of sphagnum moss
- Refrigerator space for 30 to 60 days
- Peat pots or small seed-starting trays
- Good-quality potting mix (look for one that says "seed starting" or "organic blend")
- A clear plastic bag or humidity dome
- A spray bottle
- A spot with bright, indirect light
The Five Steps, Start to Sprout
Step 1: Soak the Seeds (24 Hours)
Drop your seeds into a small container of room-temperature water and leave them for 24 hours. After soaking, any seeds floating on top are most likely hollow and not worth planting. Keep the ones that sink. Soaking wakes the seeds up and softens their tough outer coat, which is the first thing standing between a dormant seed and an actual seedling.
Step 2: Cold Stratify (30 to 60 Days)
The fridge mimics a winter on the forest floor in Hubei province.
This is the step most beginners skip, and it is also the step that decides whether anything happens at all. Place your soaked seeds on a slightly damp paper towel, fold it over, and seal it inside a small zip bag. Put the bag in the refrigerator at 35 to 40°F and leave it alone for 30 to 60 days. Write the start date on the bag.
What is happening: dawn redwood seeds will not germinate until they have experienced a winter. The cold triggers a hormonal shift inside the seed that releases dormancy. Skipping or shortening this step is the most common reason beginner attempts fail.
Step 3: Plant Shallow, and Plant a Lot
Light touches the seed surface, which is what triggers it to grow.
Fill a peat pot or seed-starting tray with moistened potting mix. Press your stratified seeds gently into the surface, no deeper than 1/8 inch (about 3mm). They need light to germinate, so do not bury them. Sow 15 to 20 seeds per pot. Mist the surface lightly.
If you only plant 3 or 4 seeds, you are statistically likely to get zero seedlings. Sow generously and you give yourself a real chance.
Step 4: Make a Mini Greenhouse
Slip the pot inside a clear plastic bag or place it under a clear humidity dome. Keep it somewhere with bright, indirect light. Avoid direct sun, which can cook seeds before they even start. Aim for daytime temperatures around 65 to 75°F and cooler nights around 55 to 60°F. The day-night temperature swing is part of what tells the seed that spring has arrived.
Open the bag once a day to let fresh air in and check that the soil is damp but never waterlogged. Mist lightly if the surface starts to dry.
Step 5: Wait, Watch, and Vent
Germination usually happens 30 to 40 days after planting. When you see green shoots, gradually loosen and then remove the plastic bag over the course of about a week. Sudden removal causes seedlings to wilt because they have not yet learned to regulate their own water. Slow transition lets them toughen up.
Once the seedlings have produced two or three sets of their feathery needles and are 3 to 4 inches tall, they are ready for a larger pot or eventually the ground.
The single biggest killer of conifer seedlings is a fungal disease called damping-off. Healthy seedlings tip over at the soil line and collapse within a day or two. An optional natural soil treatment called LABS (Lactic Acid Bacteria Serum) prevents this by introducing helpful bacteria that crowd out the disease before it can take hold. Drench your seed-starting trays with LABS at 1 ounce per 8 gallons of water, 24 to 48 hours before planting. One application is enough for a beginner. Detailed product card below.

Common Problems and How to Fix Them
Nothing has sprouted after 40 days
Most likely, stratification was too short or temperatures fluctuated too much. Wait until day 60 before giving up. If nothing has emerged by then, start a fresh batch with the full 60-day cold treatment. Low germination is normal, but zero usually points back to stratification.
Seedlings emerged but suddenly fell over
That is damping-off. The fix is prevention next time (the LABS Pro Tip above). For the current batch, increase airflow immediately, stop misting for a few days, and apply LABS as a light drench. Some seedlings may still be lost. Healthy survivors usually pull through once the moisture comes down.
Tall, thin, leggy seedlings
Not enough light. Move them to a brighter spot or move your grow light closer (12 to 14 inches above the seedlings). A gentle fan a few hours a day also strengthens stems by giving them something to push against.
Yellow needles on a young seedling
Almost always overwatering. Let the top quarter-inch of soil dry between waterings. Dawn redwoods love moisture as mature trees, but young seedlings rot easily in soggy soil.
Your First Year Outdoors
A well-mulched sapling enters its first year with everything it needs.
Once your seedlings reach 6 inches tall and have hardened off (gradual exposure to outdoor conditions over a week or two), you can plant them in the ground. Spring after the last frost is ideal. Pick a spot with full sun and well-draining soil. Dawn redwoods grow fast, so give them plenty of room. They reach 70 to 100 feet at maturity.
Dig a hole twice as wide as the root ball. Settle the seedling in, backfill with soil, and water deeply. Add a 4 to 5 inch layer of wood chip mulch around the base, keeping the mulch a few inches away from the trunk itself. The mulch keeps the soil cool, holds moisture, and slowly feeds the tree as it breaks down.
Water deeply once a week during the first growing season if rain is sparse. Avoid synthetic fertilizers. A young dawn redwood in healthy soil does not need them, and they can actually slow root development by signaling the tree to grow soft top growth instead of strong roots. Just mulch, water, and let the soil do its work.

You Can Do This
Dawn redwood is one of the most rewarding trees a beginner can attempt, partly because the bar for success is honest. A handful of seedlings from a packet of 20 is a real win. The trees that survive grow fast, look beautiful in every season, and will outlive everyone who tends them. Plant your first batch this spring, accept the losses along the way, and a few years from now you will be standing under your own grove of a species that almost did not make it out of the fossil record.
The hardest part is starting. Get the seeds in water, find a spot in the fridge, and the rest follows on its own.
