Check for fertilizer or mineral buildup

What this suggests
Brown margins after feeding, especially with crusted potting mix, can point to excess soluble salts. A crust alone does not prove injury.

Confirm the clues
• Review product strength, dose, and recent feeding dates.
• Check that water drains freely before attempting to flush a pot.

What to do now
1. Pause fertilizer while investigating.
2. For a freely draining container with confirmed buildup, follow plant-specific leaching or repotting advice. Use soil-test guidance for garden beds.

Hold off on
Do not flush a waterlogged pot or add another supplement to counteract the first.

What to watch for
Monitor new growth and root condition. Dead leaf margins will remain brown.
