If you have remaining trees, you can plant in other pots. The dawn redwood love damp soil as they grow.
The most viable seeds are the ones that are still in the cones, and November and December are the best months to collect seed. To collect redwood cones, go to an area that contains mature redwoods after a rainstorm.
Keep the redwood seeds moist, but not wet, at all times. Place the container in full sunlight or partial shade. Spread the redwood seeds on the surface of the soil. Soak redwood seeds in a glass of water overnight to speed germination. Although the trees prefer full sun for at least six hours per day, the seedlings need a gradual introduction. Seed germination will take one to two months. How long do Metasequoia seeds take to germinate? Seal inside a polythene bag and place in the fridge for 6 weeks. John Innes with vermiculite, perlite or horticultural grit and sow seeds on the surface, then just cover them with a layer of compost, vermiculite or perlite. Sowing Instructions: Sow at any time of the year. It is easy to grow and develops rapidly.How do you grow Metasequoia glyptostroboides from seed? However, the continued existence of the species has been assured by plantings throughout the temperate zones of the world. Trees have been destroyed particularly during the Cultural Revolution. In its natural habitat the dawn redwood is extremely threatened. The biggest problem is the Finnish summer, which is rather too short, cool and dry. Given a long enough autumn to harden off, it is hardy to extreme cold. In the very south of Finland conifer enthusiasts have grown the species with varying success. The 1950s plantings have died, but new plantings have been made in 20 at the warm northern edge of the Alppiruusulaakso (Rhododendron Valley), near beeches, where they are protected from autumn frosts. Autumn colour is a warm light brown.įinland lies at the very extreme of hardiness for the dawn redwood. The dawn redwood’s needle-like leaves are bright fresh green and the trunk red-brown, becoming buttressed with age. Both the dawn redwood and the swamp cypresses enjoy moist to wet conditions and loose their needles in winter. The dawn redwood resembles its American relatives the swamp cypresses ( Taxodium). The tallest of these trees are now over 20m (65 ft.) Mustila Arboretum was among the first to receive seeds, and plants grown from these seeds were sent to Gothenburg Botanic Garden as early as 1952. 
Understandably, several seed collecting expeditions were made to China in the late 1940s. Due to the war, it took two or three years to confirm that they were the first living individuals of the genus, the dawn redwoods. But then in the early 1940s some strange trees were discovered in the Hubei province in China. Earlier, the Metasequoia genus was only known through fossils.
