Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Thuja plicata Common Name: Western red cedar Family: Cupressaceae Author: D.Don. Known Hazards: None known Mature Height: 60 Mature Width: 12 Habitat: Grows singly and in small groves in moist to swampy soils, usually in shady forests, from sea-level to 1350 metres[60, 82, 99].
General Uses: Tolerant of light trimming and of reasonable exposure, this species can be grown as a hedge or as part of a shelterbelt[75].
An infusion of the boughs can be used as a hair wash to treat dandruff and scalp germs[257].
The fibrous inner bark can be pounded until it is soft and then used as a sponge for scouring dishes etc, or can be used for making rough clothing, blankets, mats, ropes, sanitary towells, a padding in a baby's cradle, nappies etc. Waterproof hats, capes, trousers, skirts etc can be made from the inner bark[257]. It is also used in thatching and as a stuffing material for mattresses[46, 61, 82, 99, 118, 171, 226, 257]. Inner bark strips have been used as a roofing material[257]. The bark has also been used to make paint brushes[257].
The inner bark has been used to make a wick for oil lamps[257].
The inner bark has been used for making baskets[257].
The roots are used in basket making, making nets etc[99]. The roots have been used in coiled and imbricated baskets[257]. The roots have been peeled, split and used to make coiled watertight baskets that can be used for boiling water[257]. The roots are harvested in the spring or early autumn when it is easier to remove the bark. The outer strips of the roots are used to make the bottom of the basket, the centre core is used in the coils and the root bark, because of its toughness, is used to make the edges[257].
The fibrous bark is used for roofing and the sides of shelters. It is also used as an insulation[61, 99].
A fibre obtained from the bark is used in making paper. The fibre is about 3.8mm long (this refers to the heartwood fibre, the inner bark fibre is probably longer)[189]. Branches can be harvested at any time of the year, they are cut into usable pieces and presoaked in clear water prior to cooking. They are then cooked for six hours or more with lye. It is difficult to rinse it to clear water because it seems to be a dye material[189]. The fibre is then hand pounded with mallets, or put through a blender or a ball mill for six hours. It is difficult to hydrate properly. The resulting paper is a rich deep brown/red[189].
The slender pliable branches are used as a high quality rope[257]. They are gathered in spring, peeled and, if thick, are split into halves or quarters. They are then twisted and worked until soft and pliable and finally woven together to make the rope[99].
A green dye can be obtained from the leaves and twigs[257].
The inner bark can be used as a tinder[257].
Wood - aromatic, light, soft, straight-grained, not strong, very resistant to decay. This resistence to decay is probably due to the exstence of powerful fungicides in the wood[226]. The wood from fallen trees remains sound for at least 100 years[226]. It is pale to dark red in colour[226]. The wood was widely utilized by many native North Amerian Indian tribes who used it for making a wide range of items including canoes, houses, totem poles, bowls, spoons, ladles and tools[226, 257]. It is currently used in making greenhouses[1, 11, 82, 171]. The wood is not of such good quality when grown in mild humid areas[1]. It makes a good fuel, burning with very little smoke, though it burns quickly[99].
