Fertilizer Burn on New Guinea Impatiens: A Common Mistake

Applying Miracle-Gro to a healthy New Guinea impatiens in a hanging basket caused rapid leaf browning and wilting—classic fertilizer burn. Chemical fertilizers are salts; when too concentrated (or applied to dry soil), they desiccate roots and foliage. The plant likely can't recover, but the lesson is invaluable.

Why It Happens

• Miracle-Gro and similar synthetics are easy to over-apply.
• Dry soil + fertilizer = root burn.
• Even "weak" solutions accumulate salts in containers.

Prevention Rules

1. Water thoroughly before fertilizing—never feed a thirsty plant.
2. Use half-strength or less; apply monthly, not weekly.
3. Consider slow-release fertilizers (Osmocote, Proven Winners) for steady, safe feeding.
4. Flush pots occasionally with clear water to leach salts.

Every gardener kills plants learning this. It's not failure—it's initiation. Replace the plant, adjust the routine, and grow on.
