Troubleshooting
Cassumunar Purple Ginger problems — and how to fix them
Cassumunar Purple Ginger (Zingiber purpureum) 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.
Root-knot nematodes
Microscopic nematodes can attack the large, fleshy rhizomes causing galling and stunted growth; improve soil health with beneficial nematodes, avoid replanting in known nematode-infested ground, and practise crop rotation where possible.
Soft scale and mealybugs
Colonies of scale insects and mealybugs can build up on stems and leaf axils in warm, sheltered conditions; inspect plants regularly and treat at the first sign with horticultural oil or insecticidal soap, targeting the undersides of leaves.
