Care Guide

Watering

Water regularly to keep soil moist but not soggy.

Fertilization

Apply a balanced fertilizer as new growth emerges.. Fertilize monthly during the active growing season.

Banana Peel Tea:Steep chopped banana peels in water for 24-48 hours. Strain and use the liquid to water the base of the plant to encourage vibrant lantern development. Discard solids in compost to avoid attracting pests.
Pruning
  • Cut stems at the base in early autumn if harvesting lanterns for dried arrangements;
  • Remove dead foliage and stems in late winter or early spring before new growth begins;
  • Regularly thin out creeping rhizomes to prevent the plant from aggressively overtaking garden beds.
