How to grow

Cultivation

Suitable for growing in any moderately fertile garden soil, in sun or partial shade, including very dry, free-draining soils, and heavy clays, as long as they are not prone to waterlogging. See pyracantha cultivation

Propagation

Propagate by semi-ripe or hardwood cuttings, or by seed sown in spring, after three months of cold stratification, bearing in mind that cultivars won't usually come true from seed and seed raised plants can be of variable quality

Suggested planting locations and garden types
  • Cottage and informal garden
  • Wildlife gardens
  • City and courtyard gardens
  • Coastal
  • Low Maintenance
  • Hedging and screens
  • Flower borders and beds
  • Climber and wall shrubs
Pruning

Flowers are produced mainly on stems produced the previous year, so pruning should aim to retain as much two year old growth as possible. Prune out unwanted growth and on mature shrubs, twenty percent of older wood, after flowering has finished each year

Pests

May be susceptible to aphids, woolly aphid, caterpillars, brown scale and leaf-mining moths

Diseases

May be susceptible to pyracantha scab, honey fungus and fireblight
