How to Grow

Cultivation

Grow in peat-free, loam-based potting compost, in full light with shade from hot sun. Water moderately in the growing season, preferably with rainwater as plants dislike tapwater. Apply a balanced liquid feed monthly in the growing season; water sparingly in winter. Top dress or pot on in spring. See Dracaena for further advice

Propagation

Propagate by semi-ripe cuttings in late spring to early summer; bottom heat may be required for rooting

Suggested planting locations and garden types

  • Houseplants
  • Low Maintenance
  • Conservatory and greenhouse

Pruning

No pruning required, although weak stems may be shortened to 15cm in spring, and the resulting cutting used to propagate a new plant

Pests

May be susceptible to scale insects, glasshouse red spider mite, thrips and mealybugs

Diseases

Generally disease-free
