How to Grow

Cultivation

Cultivated for their very rapid growth as specimen trees and useful for 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. It has the potential to become a nuisance. For more advice see tree cultivation

Propagation

Propagate from hardwood cuttings

Suggested planting locations and garden types

  • Architectural
  • Hedging and screens

Pruning

Pruning group 1 in late summer to avoid bleeding from pruning cuts but established trees need little pruning. Suckers can be removed 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
