Top sturdy stems and replant the cuttings; the thick stems root slowly but reliably.
Frequently asked questions
Why is the new growth on my Ammannia pale or whitish?
Pale, washed-out tips on Ammannia are the classic sign of iron deficiency — this genus is one of the hungriest iron feeders in the hobby. Dose a chelated iron or comprehensive micro mix several times a week and new leaves should come in with proper bronze-orange color.
Does Ammannia gracilis need CO2?
It will survive without injection in soft, well-lit water, but it grows leggy and dull. With CO2 it transforms — larger leaves, saturated color, and a sturdy upright habit. Treat CO2 as strongly recommended rather than strictly required.
