Troubleshooting
Green Rotala problems — and how to fix them
Green Rotala (Rotala sp. 'Green') 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.
Yellowing lower leaves
Natural die-off of shaded lower nodes; trim and replant healthy top cuttings regularly.
Slow growth without CO2
Rotala responds dramatically to CO2 injection. Without it, grow under moderate light and dose liquid carbon supplements.
Algae on older leaves
Aging leaves attract algae; regular pruning removes affected growth and maintains plant health.
Stem collapse at substrate
Indicates rot; replant a healthy cutting. Improve water circulation and avoid overcrowding.
Loss of green colour
Nitrogen deficiency or excessively high light causes bleaching. Adjust lighting period and increase N dosing.
