Echinodorus cordifolius problems — and how to fix them
Echinodorus cordifolius (Echinodorus cordifolius) 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.
Iron-deficiency yellowing
Pale new leaves with green veins from low iron. Dose iron-rich root tabs and liquid iron to a high-demand plant.
Outgrowing the tank
Vigorous and large, it can shade smaller plants and grow out of the water. Thin leaves and trim emersed growth as needed.
Holey, melting old leaves
Potassium shortage or natural turnover. Remove spent leaves at the base and supplement potassium.
Browning emersed leaf edges
Dry air on above-water leaves causes crisping. Raise humidity around emersed foliage or keep the plant fully submerged.
