Watering

Banana peel compost tea:Compost banana peels for 4–6 weeks; steep in water for 24 hours, dilute 1:20, and apply as a root drench to avoid leaf burn
Pruning
  • Remove spent flower stalks after blooming to direct energy to bulb growth
  • Trim yellowing foliage in late autumn after it dies back naturally
  • Thin overcrowded bulbs every 3–4 years in early spring to improve air circulation and flowering
