Lobster Claw Heliconia problems — and how to fix them
Lobster Claw Heliconia (Heliconia rostrata) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Glasshouse red spider mite
The RHS lists glasshouse red spider mite (Tetranychus urticae) as a primary pest; fine webbing and pale stippling appear on the upper leaf surface — raise humidity, improve ventilation, and apply biological control (Phytoseiulus persimilis) or neem oil.
Root and stem rot
Overwatering or poorly drained compost causes Pythium or Fusarium root rot; the pseudostem base collapses and the plant rapidly declines — remove affected rhizome sections, treat with a fungicide drench, and repot into fresh, free-draining mix.
