Are dawn redwoods self pollinating?
Since its discovery in China, there has been a rallying cry for the conservation of dawn redwood trees. Since the trees are re-planted individually, they must rely on self-fertilization to pollinate their cones, resulting in lower genetic diversity for the species and making them more prone to pests.

The Dawn Redwood has been called “a living fossil” because it was first discovered in Japan by Miki in 1941, then found growing in the wild in China. The species is over 50 million years old.
What happens to a dawn redwood when it is crowded?
1) M etasequoia does not like to be crowded; in fact, when a dawn redwood grows in close proximity to another tree, it will do one of two things, depending on conditions: First, it has the propensity to simply die. Secondly it may grow, but very slowly and virtually devoid of any branches or foliage on the shady side.
Why is the dawn redwood called a living fossil?
Also called Water Larch. A deciduous conifer native to central China and is fast becoming a favorite North American ornamental. The Dawn Redwood has been called “a living fossil” because it was first discovered in Japan by Miki in 1941, then found growing in the wild in China.

While it prefers moist conditions, the tree can withstand some flooding and has some drought tolerance.
What kind of tree is a dawn redwood?
An ancient tree that knew the dinosaurs but is well-suited to modern landscape plantings. Dawn Redwood is a deciduous conifer producing small, round 1/2″ to 1″ cones. It has a neat pyramidal shape in youth, maturing into a more rounded crown.
Can a dawn redwood be propagated from cuttings?
Propagating Dawn Redwood. Dawn redwood can be propagated from hardwood cuttings. Because the plant is very fast growing, propagated trees can become contributing landscape specimens within a few years. If you take cuttings in early spring, you will be able to plant the saplings by fall.
