Troubleshooting
Water Hedge problems — and how to fix them
Water Hedge (Didiplis diandra) 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.
Green leaves (no red)
Increase PAR, iron dosing, and CO2 levels. Red colouration is light- and nutrient-dependent.
Leaf drop after planting
Transitional melt is common. Trim and replant healthy top cuttings in fresh substrate.
Pinhole damage on leaves
Potassium deficiency; dose a potassium supplement and check overall macro balance.
Slow growth
Without CO2 injection, growth is very slow. Add CO2 or use a liquid carbon supplement.
Algae colonisation
Slow-growing stems in shaded lower zones accumulate algae; trim aggressively and increase flow.
