Dwarf Jamaican Heliconia problems — and how to fix them
Dwarf Jamaican Heliconia (Heliconia stricta) 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.
Brown leaf margins
The most common complaint, caused by insufficient humidity or hard tap water. Raise humidity and switch to rainwater or filtered water if the problem persists.
Sparse or absent flowering
Insufficient light is the usual cause. Ensure the plant receives maximum available sun, and supplement with a high-output grow light if natural light is limited in winter.
Overcrowded rhizomes
Clumps become congested after 2-3 years, reducing vigour and flowering. Divide rhizomes in spring and repot with fresh, enriched compost.
Spider mites
Common in warm, dry conditions. Increase humidity and treat with insecticidal soap or neem oil; check the undersides of leaves where mites typically congregate.
Scale insects
Brown bumps along pseudostems and leaf midribs indicate scale. Treat with a systemic insecticide or wipe with isopropyl alcohol for minor infestations.
