Calathea is a tropical evergreen perennial plant native to the rainforest floors of Central and South America, belonging to the Marantaceae family, also known as the prayer plant family due to its unique leaf movements. It is prized for its striking, patterned foliage that comes in various shapes, sizes, and vibrant colors, often with purplish undersides, making it a popular ornamental indoor plant.
Advantages and Significance of Calathea Plants
- Air Purification: Calatheas help clean indoor air by filtering toxins such as benzene and formaldehyde, improving air quality and reducing allergens.
- Humidity Enhancement: Through transpiration, Calatheas release moisture into the air, increasing indoor humidity, which benefits skin, respiratory health, and overall comfort in dry environments.
- Stress Reduction and Mental Well-being: Caring for Calathea plants can lower stress levels and promote relaxation, while their gentle leaf movements create a calming atmosphere.
- Aesthetic Appeal: With their bold, decorative leaves, Calatheas add a tropical, vibrant touch to homes and offices, enhancing interior décor and creating a lush ambiance.
- Cultural and Symbolic Significance: In South American cultures, Calathea leaves symbolize spiritual protection and interconnectedness of life. Their nightly leaf-folding behavior is associated with prayer and mindfulness, reflecting serenity and energy conservation.
- Pet and Child Friendly: Calatheas are non-toxic, making them safe choices for households with pets and children.
If you’re growing houseplants in Pune and have a beautiful Calathea plant that’s showing curled or browning leaves, you’re likely asking, “Why are my Calathea leaves curling?” You’re not alone. Calatheas are striking tropical houseplants known for their bold patterns and unique leaf movements—but they’re also famously finicky.
In this in-depth guide tailored for indoor plant lovers in Pune, we’ll explore the 9 most common reasons why Calathea leaves curl, along with solutions you can apply immediately. Whether you’re a hobbyist or considering purchasing your first Calathea in Pune, this guide blends expert tips, local insights, and pro care advice for thriving houseplants.
1. Underwatering and Dry Soil
The most frequent cause of curling leaves in Calatheas is underwatering. Pune’s dry winter air and hot summers can dehydrate your plant faster than expected. When the plant lacks sufficient moisture, it curls its leaves inward to conserve water.
Signs:
- Crisp, curled leaves
- Drooping appearance
Solution:
- Water when the top 1 inch of soil feels dry.
- Use the bottom watering method for deeper absorption.
- During Pune’s hot months (April to June), increase watering frequency slightly.
Pro tip for Pune residents: Install a simple soil moisture meter to avoid guesswork during temperature fluctuations.

2. Overwatering and Root Rot
On the flip side, too much water—especially during Pune’s monsoon season—can suffocate the roots, causing root rot and curling leaves.
Signs:
- Mushy soil
- Yellowing or wilting leaves
- Foul smell
Solution:
- Repot in well-draining potting mix (cocopeat + perlite + compost).
- Ensure pots have drainage holes.
- Avoid watering on rainy days if soil remains moist.
3. Low Humidity
Calatheas are tropical plants that need 50–60% humidity, which can be lacking in indoor spaces in Pune—especially with constant fan use or air conditioning.
Fix:
- Mist your plant every morning.
- Use a humidifier, especially in air-conditioned rooms.
- Place your plant near other houseplants to build a humid microclimate.
Buy humidity trays or pebble trays locally at Sanjay Nursery or other Pune garden centers.
4. Poor Water Quality
Tap water in Pune is often treated with chlorine and fluoride, which Calatheas don’t tolerate well. The chemicals can build up in the soil, resulting in leaf curl and browning tips.
Solution:
- Switch to filtered, RO, or rainwater.
- Let tap water sit overnight to allow chemicals to dissipate.
Pune’s monsoon rains make rainwater collection easy—store and use it for watering indoor plants like Calathea.
5. Temperature Stress & Drafts
Calatheas dislike extreme temperature swings. Pune’s winters can drop below their comfort zone, while peak summers may dry them out rapidly.
Fix:
- Keep plants indoors away from windows during cold nights.
- Avoid placing plants under ceiling fans or near air vents.
- Maintain indoor temps between 18°C to 29°C for healthy growth.
6. Light Stress: Too Much or Too Little
Direct sunlight, especially in Pune’s peak summer, can scorch Calathea leaves. However, too little light can also affect their health.
Best Position:
- Near an east-facing window with sheer curtains.
- Avoid harsh western sunlight in summer.

7. Fertilizer Burn
Overuse of fertilizers, especially chemical-based ones, can cause salt buildup in the soil, stressing the plant and leading to curling leaves.
Solution:
- Use a diluted organic fertilizer once a month.
- Avoid feeding in winter.
- Flush soil every 6–8 weeks using filtered water to clear residue.
Where to buy: Look for Calathea-safe fertilizers at local Pune nurseries or order organic brands online.
8. Pest Infestation
Spider mites, mealybugs, and aphids are not very common, but they can attack indoor Calatheas, especially during seasonal changes.
Signs:
- Tiny webs
- Sticky residue
- Misshapen curling leaves
Treatment:
- Wipe leaves with neem oil and water solution.
- Isolate affected plants.
- Check the undersides of leaves weekly.
9. Natural Leaf Movement
Don’t be alarmed if your Calathea’s leaves fold up at night and spread out during the day. This is a natural circadian rhythm known as nyctinasty.
No fix required—your plant is just following its biological clock!
