Cryptocoryne pontederiifolia problems — and how to fix them
Cryptocoryne pontederiifolia (Cryptocoryne pontederiifolia) 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 after planting
Existing leaves dissolve when the plant transitions to new conditions. Leave the rhizome in place; fresh leaves emerge adapted to the tank.
Yellowing leaves
Iron or general nutrient shortage. Supplement with root tabs and a liquid fertiliser containing iron and micronutrients.
Algae on broad leaves
Slow growth plus excess light invites spot and brush algae on the wide blades. Reduce lighting and improve nutrient balance.
Failure to spread
Lean substrate or being uprooted repeatedly stops runner production. Feed the roots and let it settle undisturbed.
