Uster's Water Trumpet problems — and how to fix them
Uster's Water Trumpet (Cryptocoryne usteriana) 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
Occurs after planting or large water changes. Remove dead leaves, maintain stable conditions, and the rhizome will regrow.
Nutrient deficiency
Yellow or pale leaves indicate insufficient iron or macronutrients. Add root tabs and supplement with liquid fertiliser.
Slow establishment
Can take 6-10 weeks to root properly. Avoid moving or disturbing the plant during this period.
Overcrowding
Mature plants spread via runners; remove excess daughter plants periodically to maintain good water circulation.
