Sarapiqui Heliconia problems — and how to fix them
Sarapiqui Heliconia (Heliconia sarapiquensis) 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.
Pseudostem rot in cool conditions
Below 12°C (54°F) the soft pseudostems rapidly develop wet rot at the base; even brief cold snaps can collapse an established plant. In heated greenhouses, monitor minimum overnight temperatures carefully and increase heating before autumn temperatures drop.
Scale insects
Armoured or soft scale colonies develop on pseudostem bases and leaf undersides, causing yellowing and stunted growth. Treat with horticultural oil or a systemic insecticide in early infestation; scrape off established colonies manually before applying contact treatment.
