Metasequoia glyptostroboides
Dawn Redwood
The Dawn Redwood is a fast-growing deciduous conifer with ancient lineage — a true living fossil once thought extinct and rediscovered in China in the 1940s. It's highly regarded for bonsai due to its soft, opposite, feathery needles that turn bronze in fall, its buttressed trunk with reddish bark, and its rapid, predictable growth.

Care Guide
Placement
Full sun to partial shade
Provide afternoon shade in very hot climates.
Watering
High
Soil should remain evenly moist; never let it dry out completely.
Fertilization
High nitrogen in spring
Switch to balanced or low-nitrogen mid-summer to avoid leggy growth.
Pruning
Structural in early spring, maintenance through summer
Pinch or prune vigorous shoots to encourage ramification.
Wiring
Spring or Autumn
Use guy wires when possible; branches are brittle and prone to scarring.
Repotting
Every 1 - 2 years
Repot in early spring before bud break; root growth is vigorous.
Propagation
Cuttings or seed
Air layering possible but less common than softwood cuttings.
Winter: Protect roots from deep freeze in containers.
Summer: Ensure consistent moisture during peak heat.
Zone 8b: Protect roots if temps < 20 F
Seasonal Calendar
