Mint Plant Killed by Undiluted Urine: Emergency Flushing

The Damage

Urine is very high nitrogen. Daily undiluted application for 10 days burned the roots—stems are dry, brittle, leaves fallen.

Rescue Attempt

• Remove drain tray.
• Run water slowly through pot at sink for several cycles to leach out urine.
• If roots aren't totally dead, new shoots may appear.

Future Fertilizing

Use urine once monthly, diluted. Or use balanced fertilizer like Miracle-Gro for safer, complete nutrition.
