Troubleshooting
Zizania latifolia problems — and how to fix them
Zizania latifolia (Zizania latifolia) 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.
Aggressive rhizome spread
Spreads strongly and is an invasive wetland weed in parts of North America and New Zealand. Contain it in a lined bed, basket or tub and never plant it in or near open natural waterways.
No swollen stem base forms
The edible 'water bamboo' only develops when the symbiotic smut fungus is present in the plant. Stock from a known cultivated clone that carries the fungus; wild seed-grown plants stay grassy and inedible as a vegetable.
Flopping or thin canes
Result from too little light, poor fertility, or crowding. Give full sun, feed well, and divide congested clumps to restore strong upright growth.
Drying out
Loss of standing water during the growing season stunts the plant and the harvest. Keep the root zone flooded and the water level steady.
