How to grow

Cultivation

Grow in moderately fertile soil; will tolerate poor dry soils. Larger trees develop brittle branches and suckering may be a problem; it has the potential to become a nuisance

Propagation

Propagate by seed sown in a cold frame in autumn

Suggested planting locations and garden types
  • Low Maintenance
Pruning

Pruning group 1 or Pruning group 7; pruning should be done in late summer or early autumn to prevent bleeding; sucker removal if necessary, in autumn

Pests

Generally pest free

Diseases

Generally disease free but in more recent years there have been Frisia dieback problems
