Care Guide
Keep soil evenly moist; water when top 1 cm of substrate feels dry
Apply diluted, balanced liquid feed once every 6 weeks. Avoid high-nitrogen fertilizers which can promote weak, leggy stem growth
Banana peel tea:Steep fully composted banana peels in water for 3 days, dilute 1:20 for root drench; discard solid peels to prevent odor and pest attraction- Cut back brown, spent fertile stems after spore release in early spring
- Thin overcrowded sterile stems to improve airflow and reduce colony spread
- Trim spreading rhizomes in late autumn to contain invasive growth in garden beds
