About the genus
Populus are deciduous trees, mostly very fast-growing and large, with male and female catkins on separate trees, opening before the leaves. Male catkins are the more ornamental, female ones can be a nuisance from the cottony, wind-blown seeds

Care notes
CultivationCultivated for their very rapid growth as specimen trees. Useful as windbreaks. Tolerant of any soil other than constantly waterlogged soils. Avoid growing within 40m of buildings as the vigorous root systems may damage drains and foundations, particularly on clay soils; has the potential to become a nuisance
PruningPruning group 1 in late summer to avoid infection from bacterial canker and bleeding from pruning cuts. Train as a central-leader standard. Never allow competing leaders to develop. Established trees need little pruning; sucker removal in autumn or winter
PropagationPropagate by hardwood cuttings in winter and suckers in autumn or late winter
Pest resistanceMay be susceptible to leaf beetles, sawflies and caterpillars
Disease resistanceMay be susceptible to leaf spots, poplar bacterial canker, tree rusts and honey fungus
