An easily grown plant that does well in a heavy cold damp soil. Prefers a deep rich well-drained circumneutral soil, growing best in the south and east of Britain. Growth is much less on wet soils, on poor acid soils and on thin dry soils. It does not do well in exposed upland sites. It dislikes shade and is intolerant of root or branch competition. A fast-growing but short-lived species, it reaches maturity in 40 - 50 years and rarely lives as long as 100 years. Like the quaking aspen (Populus tremuloides) the leaves of this species rustle even in light breezes. Poplars have very extensive and aggressive root systems that can invade and damage drainage systems. Especially when grown on clay soils, they should not be planted within 12 metres of buildings since the root system can damage the building's foundations by drying out the soil. Dioecious. Male and female plants must be grown if seed is required. Hybridizes freely with other members of this genus.

Inner bark. A pleasant sweet flavor. There are no more details but inner bark is often dried, ground into a powder and then used as a thickener in soups etc or added to cereals when making bread. Young shoots - cooked. The cottony fruit has been used by children as a chewing gum. (This almost certainly refers to the seedpods)

Seed - must be sown as soon as it is ripe in spring. Poplar seed has an extremely short period of viability and needs to be sown within a few days of ripening. Surface sow or just lightly cover the seed in trays in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the old frame. If sufficient growth is made, it might be possible to plant them out in late summer into their permanent positions, otherwise keep them in the cold frame until the following late spring and then plant them out. Most poplar species hybridize freely with each other, so the seed may not come true unless it is collected from the wild in areas with no other poplar species growing. Cuttings of mature wood of the current season's growth, 20 - 40cm long, November/December in a sheltered outdoor bed or direct into their permanent positions. Very easy. Suckers in early spring.
