How to Grow

Cultivation

Cultivated for very rapid growth as a specimen tree; useful as windbreaks. This species will tolerate most soils except those that are constantly waterlogged and in full sun. Avoid growing within 40m of buildings as the vigorous root system may damage drains and foundations, particularly on clay soils; has the potential to become a nuisance

Propagation

Propagate by hardwood cuttings in winter and from suckers in autumn or late winter

Suggested planting locations and garden types

  • Coastal
  • Cottage and informal garden
  • Flower borders and beds

Pruning

Pruning group 1 in late summer to avoid bleeding from pruning cuts. 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
