Material uses
A fibre obtained from the stems is used in making paper[5]. The stems are harvested in spring or summer, the leaves are removed and the stems steamed until the fibres can be stripped. The fibres are cooked for 2 hours with lye and then beaten with mallets or put through a blender. The paper is red/brown in colour[5]. The trees are often used in erosion control, their roots forming dense networks that stabilize stream banks[3]. The bark is a good source of tannin[6][7]. A decoction or infusion of the bark can be used as a hair wash to make the hair grow[4].
Wood - not durable, light, soft and weak but does not splinter, warp or check[8][9]. The wood is tough and fairly strong according to another report[2]. It weighs 27lb per cubic foot[7]. Used where strength is not important, for artificial limbs, barn floors etc[8][10][9]. A good charcoal is also obtained from the wood[11].Medicinal uses(Warning!)
The leaves are used internally in the treatment of minor feverish illnesses and colic[17]. The leaves can be harvested throughout the growing season and are used fresh or dried[17].
The fresh bark contains salicin, which probably decomposes into salicylic acid (closely related to aspirin) in the human body[18]. This is used as an anodyne and febrifuge[18] and as an ingredient of spring tonics[3].Ecology

Propagation
Cuttings of mature wood of the current year's growth, November to February in a sheltered outdoor bed or planted straight into their permanent position and given a good weed-suppressing mulch. Very easy. Plant into their permanent positions in the autumn.
Cuttings of half-ripe wood, June to August in a frame. Very easy.Practical Plants is currently lacking information on propagation instructions of Salix nigra. Help us fill in the blanks! Edit this page to add your knowledge.
Cultivation
A fast-growing but relatively short-lived species, it can reach 15 metres tall within 10 years from seed in the wild[3]. Twigs tend to break off easily in storms, these will then often root and grow into new trees[22]. A good bee plant, providing an early source of nectar[20]. Trees are impatient of root disturbance and should be moved regularly before being planted in their permanent positions, which is best done whilst the plants are young[20]. The root system is rather aggressive and can cause problems with drains[21]. Plants should not be grown within 10 metres of buildings. Closely related to Salix caroliniana, hybridising with that species where their ranges overlap[23]. This species is also likely to hybridize freely with other members of this genus[21]. Although the flowers are produced in catkins early in the year, they are pollinated by bees and other insects rather than by the wind[20]. Plants in this genus are notably susceptible to honey fungus[21]. Seedlings are very fast-growing, they can reach 1.2 metres tall in their first year[20]. Plants are used commercially for papermaking[5].
Dioecious. Male and female plants must be grown if seed is required.Crops
