An incredibly fast-growing tree perfect for a quick windbreak, quick shade, firewood production, and feeding sheep and cows (that's what we do!). Poplars are adaptable in most conditions but do not do as well in excessively dry soils. Can tolerate wet soils well. Can grow more than 5 ft a year. Will grow to be a full-sized tree. Hybrid Poplar is a cross between Black Poplar and Eastern Cottonwood. Poplars can be directly planted as a cutting and will root well if kept moist the first spring.
