Troubleshooting
Yellow Cabomba problems — and how to fix them
Yellow Cabomba (Cabomba aquatica) 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.
Overly fast surface growth
Trim stems before they reach the surface to prevent shading; replant trimmed tops to increase planting density.
Etiolated, sparse whorls
Indicates insufficient light; increase lighting intensity or duration to restore dense, compact growth.
Stem fragility and breaking
Handle gently when planting or rearranging; use fine-tipped tweezers and support stems at multiple points.
Poor anchorage
Large buoyant stems can float free; weight bunches with plant anchors or tie loosely to a small stone initially until roots form.
Algae on older lower leaves
Remove lower leaves showing algae, increase water circulation past the planting area, and ensure balanced nutrient dosing.
