Calathea Sunburn Rescue: Prune Damaged Leaves, No Fertilizer, Patience

Your calathea got 5 hours of direct sun—leaves badly burned. Burned leaves NEVER heal. Here's the recovery plan:

Immediate Action

1. Remove severely damaged leaves (up to ½-¾ total if needed)
2. If >¾ damaged: Remove worst half now, rest one-by-one as new leaves emerge
3. Move to low/medium indirect light — NO direct sun
4. Water properly (top 1-2" dry, then water to drain)
5. ZERO fertilizer until mostly new healthy growth

Why No Fertilizer?

Fertilizer stresses recovering plants. Calatheas are EXTREMELY sensitive to overfertilizing even when healthy. Stressed + fertilizer = death spiral.

Future Fertilizing (After Recovery)

• 1/3 package strength liquid fertilizer
• Dilute 1:2 with distilled water
• Every 6 weeks max

The Silver Lining

Maranta family plants (Calathea, Prayer Plant) often regrow larger and healthier after heavy pruning. One expert cut a Prayer Plant to scraggly stems intending to discard—it regrew magnificently!

Water Note

Use DISTILLED WATER ONLY. Calatheas react to fluoride/chlorine with instant brown edges.

Recovery takes weeks. The plant will look rough, then suddenly explode with perfect new growth. Trust the process.
