Description and Growing Information

General DescriptionRaven Dawn Redwood is a deciduous conifer that grows in a conical profile with soft textured, deep green foliage and is a fast grower; it can grow up to 30 m tall. (MBG, n.d)
ID CharacteristicIt is a deciduous conifer that can be identified by its uniform pyramidal growth and low branching habit. This Redwood has deeply furrowed bark, and better resistance to foliar diseases. The needles are opposite on the stems. (MBG, n.d)
ShapeGrows in a conical shape up to 30 m tall. (MBG, n.d)
LandscapeSuperb in large areas and is an excellent specimen or street tree. It can be used in lawns, gardens, parks, campuses, golf courses and commercial grounds. (Dirr, 2009, p. 749)
PropagationCan be propagated by hardwood cuttings at the start of summer, the size of cutting should be 2.5 m. Sever the cutting at a 45-degree angle 3 mm below the leaf node (Degnan, n.d.). Take off the new growth and plant them in topsoil. They require water every day, or they are going to dry out. You also want to put them somewhere warm (BerringtonGardens 2020).
CultivationIt grows best in full sun, moist, humusy, well-drained soils, but can tolerate moist to wet soils. (Dirr, 2009, p. 749)
PestsThe tree can suffer from some canker infections. Foliage may be affected by Japanese beetles that will feed on the leaves. Otherwise, no serious pest or disease problems. (Dirr, 2009, p. 749)
