Troubleshooting
Wendt's Water Trumpet problems — and how to fix them
Wendt's Water Trumpet (Cryptocoryne wendtii) 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.
Crypt melt
Sudden leaf collapse after transplanting or environmental change is common ('crypt melt'). Remove decaying leaves, maintain stable conditions, and new growth will emerge from the intact rhizome.
Algae overgrowth
Too much light or excess nutrients encourages algae on leaves. Reduce light intensity or duration, and introduce algae-eating tank inhabitants if used in an aquarium.
Stunted growth
Nutrient deficiency, particularly iron or potassium, causes pale or small leaves. Add root tabs or a balanced aquatic liquid fertiliser.
Rhizome rot
Burying the rhizome too deeply can cause rotting. Plant so the rhizome sits just above or at the substrate surface with only the roots buried.
Leaf holes or tears
In aquariums, grazing fish (plecos, goldfish) may damage foliage. Choose compatible tank inhabitants or use a species-only setup.
