Dawn Redwood
Metasequoia glyptostroboides
Care level: Moderate
Dawn Redwood was known only from 250-million-year-old fossils until a small living population was found growing wild in central China in 1944, making it one of the most famous 'living fossils' in botany. It's also one of the very few conifers that's deciduous, dropping its soft, feathery needles every autumn after they turn a striking coppery orange.
Full sun outdoors for the densest foliage and best autumn color; tolerates a little afternoon shade.
Water
Keep the soil consistently moist, it tolerates wet feet far better than most conifers and dislikes drying out.
Humidity
Not a significant factor outdoors; naturally at home in humid summer climates.
Soil
Rich, moisture-retentive soil; adapts to both slightly acidic and neutral pH.
Temperature
It needs winter cold outdoors. Protect the roots of a potted tree from hard frost.
Size
A tree of 19-30m in the ground; kept small as a bonsai by pruning.
Growth speed
Fast
Common mistake
Treating a Metasequoia like an evergreen and worrying when it drops all its needles in autumn is the most common misunderstanding; that seasonal bare period is completely normal for this species and fresh green growth returns reliably every spring.
Care by Season
Spring
Fresh, soft green needles emerge quickly; resume regular feeding as growth restarts.
Summer
Water generously in hot weather, this is the main growth season and the trunk thickens fastest now.
Autumn
Needles turn coppery orange before dropping entirely, a normal and attractive seasonal display, not a problem.
Winter
Needs a genuine cold dormancy outdoors; protect the roots in a pot from hard freezes but don't bring it inside.
Growing & Maintenance
Soil and pot
A rich, moisture-retentive soil. It adapts to slightly acidic and neutral pH.
Fertilising
Feed regularly from spring, as the new needles emerge.
Pests & Diseases
Common problems
All the needles turning copper and dropping in autumn
Most likely cause: Normal. It is a deciduous conifer.
What to do: Nothing to do. New needles appear in spring.
Brown, crispy needles in summer
Most likely cause: The soil dried out.
What to do: Keep the soil consistently moist and water generously in hot weather.
Dull, speckled needles
Most likely cause: Spider mites, which like dry conditions.
What to do: Rinse the foliage regularly and water more.
Twig tips dying back
Most likely cause: Twig blight.
What to do: Prune out the affected twigs with clean tools and improve the airflow.
Weak growth indoors
Most likely cause: No cold winter rest.
What to do: Keep it outdoors all year.
Pests & Diseases
Spider mites
Signs: Fine webbing and stippled, dull needles during hot, dry spells.
Treatment: Rinse foliage regularly and increase watering; mites struggle in consistently moist conditions. Check the undersides of the leaves and the crevices where the leaf stem meets the main stalk.
Root rot
Signs: Rare given this tree's wet tolerance, but can occur in stagnant, airless soil.
Treatment: Improve drainage while still keeping the soil moist, and avoid letting the pot sit in standing water.
Twig blight
Signs: Scattered dead, brown shoot tips.
Treatment: Prune out affected twigs with clean tools and improve airflow around the canopy.
FAQ
Can I keep a Metasequoia bonsai indoors?
No. Unlike many houseplant-friendly bonsai species, Dawn Redwood needs a real outdoor winter with genuinely cold temperatures to stay healthy long-term; kept indoors year-round it will weaken and eventually decline, since it never gets the dormancy it needs.
Why did my Metasequoia bonsai lose all its needles?
This is completely normal. Dawn Redwood is one of the few deciduous conifers, its needles turn copper-orange and drop every autumn, then regrow fresh and green each spring, unlike a true evergreen that would keep its foliage year-round.
How often should I water a Dawn Redwood bonsai?
Often enough that the soil never dries out. It tolerates wet soil far better than most conifers and needs generous watering in hot weather.
How much sun does a Dawn Redwood need?
It needs full sun outdoors. That gives the densest foliage and the best autumn colour, though it takes a little afternoon shade.
What colour does a Dawn Redwood turn in autumn?
Coppery orange to red-bronze. The needles then drop completely, which is normal for this tree.
How do I overwinter a Dawn Redwood bonsai?
Outdoors, because it needs a real cold dormancy. Protect the roots in the pot from hard frost, but do not bring it inside.
