Troubleshooting
Hanging Lobster Claw problems — and how to fix them
Hanging Lobster Claw (Heliconia rostrata) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Failure to bloom
The most common issue outside the tropics. Requires consistently high temperatures above 22°C, very high humidity, and full sun exposure throughout the growing season. In cooler climates, flowering is rare without a heated glasshouse.
Brown leaf edges and tips
Immediately indicates insufficient humidity. Raise ambient moisture to above 70%. Misting provides only minimal relief — a dedicated humidifier is needed.
Leaf yellowing
May result from cold temperatures, waterlogged soil, iron deficiency in alkaline conditions, or natural lower-leaf senescence. Check soil pH (ideal 5.5-6.5) and drainage.
Spider mites
Thrives in hot, dry conditions. Maintain high humidity to deter infestations and treat with neem oil or insecticidal soap at first sight. Check the undersides of all leaves.
Bacterial or fungal crown rot
Caused by water sitting in the crown of the pseudostem or poorly drained soil. Water at the base, not into the crown, and ensure rapid drainage.
