Wavy Aponogeton problems — and how to fix them
Wavy Aponogeton (Aponogeton ulvaceus) 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.
Dormancy and die-back
Like most Aponogeton species, A. ulvaceus periodically enters dormancy, shedding all leaves. This is a natural bulb rest cycle, not death. Reduce fertilization, keep the bulb in the tank, and it will re-sprout after 4–8 weeks. Removing the bulb during dormancy often leads to dehydration and death.
Algae on leaves
The wide, translucent surface is a prime algae target under high-light conditions. Reduce photoperiod to 8 hours, moderate light intensity, or introduce Amano shrimp or nerite snails to graze algae before it establishes.
Bulb rot
Results from fully burying the bulb, poor water circulation, or warm stagnant substrate. Always plant with the top half of the bulb above the substrate and ensure at least gentle water flow across the base of the plant.
