The Prayer Plant (Maranta leuconeura) is a stunning houseplant known for its vibrant foliage and unique leaf movement, but it can be tricky to care for. Many plant owners struggle with yellowing leaves, curling, brown edges, drooping, and slow growth. These issues often stem from improper watering, humidity, light conditions, or pest infestations.
In this guide, we’ll cover common prayer plant problems, their causes, solutions, and preventative care tips. If your plant is struggling, follow these steps to bring it back to health.

Common Prayer Plant Problems & Their Causes
1. Yellowing Leaves
Causes:
- Overwatering & Root Rot – Soil remains soggy, leading to oxygen deprivation in roots.
- Underwatering – Dry soil causes stress and dehydration.
- Nutrient Deficiencies – Lack of nitrogen or iron results in pale yellow leaves.
Solutions:
✅ Check soil moisture before watering—water only when the top 1-2 inches of soil are dry.
✅ Use a well-draining mix (peat, perlite, and compost) to prevent waterlogging.
✅ Apply a balanced liquid fertilizer every 4–6 weeks to maintain nutrient levels.
2. Brown & Crispy Leaf Edges
Causes:
- Low Humidity – Prayer plants need 50-60% humidity to thrive.
- Tap Water Sensitivity – Chemicals like chlorine and fluoride can damage leaves.
- Over-Fertilization – Too much fertilizer burns leaf tips, causing browning.
Solutions:
✅ Increase humidity with a humidifier, misting, or pebble tray.
✅ Use filtered, distilled, or rainwater instead of tap water.
✅ Flush soil monthly to remove fertilizer buildup.
3. Curling Leaves & Drooping Growth
Causes:
- Low Temperature & Cold Drafts – Sudden temperature drops stress the plant.
- Underwatering or Dry Soil – Leads to leaf curling and wilting.
- Too Much Direct Sunlight – Causes heat stress and leaf curling.
- Pests (Spider Mites, Thrips, Aphids) – Suck moisture from leaves, leading to curling.
Solutions:
✅ Keep temperature between 65-80°F (18-27°C) and avoid cold drafts.
✅ Provide consistent moisture without letting soil dry out completely.
✅ Place the plant in bright, indirect light, avoiding direct sun exposure.
✅ Check for pests and use neem oil or insecticidal soap if needed.
