This is a deciduous conifer native to Sichuan and Hubei provinces of China where it was discovered in 1941.
It is a fast growing tree (over 100 feet in the wild) with thick, spongy bark and bipinnate leaves which are bright green in the summer turning to red in autumn before shedding in winter.
Style : Most suitable styles for bonsai are formal or informal upright.
WARNING : Dawn redwoods grown in the ground thrive in full sunlight, but as a potted bonsai, they will dry out too quickly if placed in direct sunlight. Place the bonsai in dappled or filtered sunlight. Be extra vigilant in the summer: Check the soil every day to make sure it is moist. The tree will quickly perish if allowed to dry out.
REPOT : Every 2-5 years depending on age, in mid to late spring.
SOIL : Free draining : 80:20 grit:organic or 70:30 grit:akadama.
WATER : Keep wet but not saturated. Keep dry in winter.
PRUNE : Late summer/early autumn.
PINCH : Pinching of candles will be determined by the objective (back-budding, branch extension etc). In late summer, remove old needles to let in light.
FEED : Monthly dose of balanced feed during spring summer. Single application of slow release, low nitrogen feed in winter.
PH VALUE : 5.0 - 6.0
