🛠️

Watering

Maintain consistent soil moisture during active growth period

Fertilization

Apply diluted organic feed once at bulb emergence. Use low-nitrogen organic feed to support bulb development rather than leaf growth

Banana peel compost tea：Fully compost banana peels first; dilute 1:40 with water for root drench, avoid applying directly to foliage

Pruning

Remove spent flower stems after blooming to redirect energy to bulb growth
Allow foliage to die back naturally before trimming to nourish the underground bulb
Thin overcrowded clumps every 3–4 years in late summer to improve airflow and bulb vigor
