Diagnosing Brown Leaf Tips on Prayer Plants After Repotting

Repotting Is the Likely Culprit

Symptoms starting 2–3 weeks after repotting, with yellow→brown tips/edges, point to root disturbance or watering issues.

Check These Factors

1. Pot size: New pot should be only 1–2 inches wider. Larger pots hold excess moisture.
2. Root loosening: Did you tease/prune circling roots before repotting? If not, roots stay in old ball, new soil stays wet.
3. Watering adjustment: After repotting, water less frequently. Wait until top ¼ of mix is dry.
4. Soil composition: Perlite in the new mix adds fluoride, which burns Maranta tips.
5. Water quality: Hard tap water causes tip burn. Switch to distilled/filtered/rain water.

pH and Calcium

Calcium deficiency is rare. Soil pH may be off. Test with a meter; if below 5.5, add a pinch of horticultural lime to raise pH and supply calcium.

Action Plan

• If pot too large, move to smaller one.
• Water only when top ¼ dry.
• Use pure water.
• Trim brown tips (won't recover).

New growth should normalize once roots establish.
