Troubleshooting
Grass-Leaved Ginger problems — and how to fix them
Grass-Leaved Ginger (Zingiber gramineum) 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.
Rhizome rot
Caused by overwatering or poorly draining soil, especially when the plant is dormant in winter. Lift and inspect rhizomes if stems collapse at the base; discard soft, foul-smelling sections and replant in fresh, well-draining medium.
Spider mites
In warm, dry indoor conditions, spider mites colonise the undersides of leaves, causing fine stippling and bronzing. Increase humidity and treat with insecticidal soap or neem oil spray applied weekly until clear.
