How to Grow

Cultivation

Cultivated 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

Propagation

Take hardwood cuttings in winter and suckers in autumn or late winter

Suggested planting locations and garden types

  • Architectural

Pruning

Pruning 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

Pests

May be susceptible to leaf beetles, sawflies and caterpillars

Diseases

May be susceptible to leaf spots, poplar bacterial canker, tree rusts and honey fungus
