Water Hyacinth Turning Brown: Stop Miracle-Gro, Stop Trimming

Why They're Burning

Miracle-Gro (high nitrogen, urea) burns floating plant roots. Trimming damaged tips stimulates more tender growth that burns again—a vicious cycle.

Recovery

  1. Cease all fertilizer.
  2. Stop trimming.
  3. Do a 50% water change to flush nutrients.
  4. Add a barley straw mini-bale.
  5. Wait 2–3 weeks; new growth will be healthy.

Future Feeding

Use aquatic plant tablets (slow-release) pushed into potted plants only. Floaters get nutrients from water column.
