Aponogeton crispus problems — and how to fix them
Aponogeton crispus (Aponogeton crispus) 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.
Bulb rot
Burying the whole bulb or leaving a damaged one in stagnant substrate causes it to soften and rot. Plant with the top of the bulb just exposed in clean, circulating water and discard any mushy tubers.
Dormancy and leaf dieback
Plants periodically shed most leaves and rest. Leave the firm bulb in place (or store it cool and damp); it usually reshoots within weeks, and a rest period actually prolongs its life.
Algae on leaves
Slow growth or excess light coats the translucent leaves with algae. Improve light balance, add nutrients and CO2 to spur fresh growth, and add algae-grazing fish or shrimp.
Pale, melting leaves
Newly imported bulbs often 'melt' as submerged leaves replace emersed-grown ones, and nutrient or iron shortage keeps them pale. Be patient, dose iron-rich fertiliser and root tabs, and trim dead foliage.
