2. Ideal Growing Conditions

Creating the right environment is key to ensuring your Calathea Stella thrives. Here’s what you need to know:

Light Requirements

Prefers bright, indirect light.
Avoid direct sunlight, as it can scorch the leaves and cause them to lose their vibrant color.
Can tolerate low light conditions but may grow slower and produce less striking foliage.
Ideal placement: Near a north or east-facing window with sheer curtains to diffuse light or in a well-lit room with indirect exposure.

Temperature & Humidity

Thrives in temperatures between 65–80°F (18–27°C).
Avoid cold drafts, sudden temperature changes, and heating vents, as they can stress the plant.
Requires high humidity levels (above 50%) to maintain its lush appearance.
Ways to increase humidity:
- Use a humidifier to maintain a consistent moisture level in the air.
- Mist the leaves regularly, but avoid overdoing it to prevent fungal issues.
- Place a pebble tray with water under the pot to create a humid microclimate around the plant.
- Group plants together, as they naturally release moisture into the air.

Soil & Potting Mix

Prefers a well-draining, peat-based soil to prevent root rot.
A mix of peat moss, perlite, and orchid bark ensures proper aeration and moisture retention.
Avoid heavy, compacted soils that retain too much moisture, leading to fungal infections.

3. Watering Your Calathea Stella

Watering is one of the trickiest aspects of Calathea Stella care. Too much or too little can cause problems.

How Often Should You Water?

Water when the top inch of soil feels dry to maintain optimal moisture levels.
Typically, this means watering once or twice a week, depending on humidity levels and season.
Reduce watering in winter when the plant’s growth slows down, as excessive moisture can lead to root rot.

Best Watering Practices

Use filtered, distilled, or rainwater to avoid chlorine and fluoride, which can cause leaf browning and tip burn.
Water thoroughly but ensure excess water drains out through drainage holes to prevent waterlogging.
Never let the plant sit in standing water, as this can lead to fungal infections and root rot.

4. Fertilizing for Healthy Growth

When & How to Fertilize

Feed with a balanced liquid fertilizer (diluted to half strength) once a month during the growing season (spring and summer).
Avoid fertilizing in fall and winter when the plant enters dormancy.
Over-fertilization can lead to salt buildup and leaf burn, so always follow the recommended dosage.
Organic options like worm castings or compost tea can be used for a more natural approach.

5. Pruning & Maintenance

How to Prune

Trim any yellow, damaged, or brown leaves to encourage new growth and maintain the plant’s aesthetics.
Use clean, sharp scissors or pruning shears to make precise cuts and avoid stress on the plant.
Regular pruning helps maintain the plant’s shape, promotes airflow, and prevents fungal growth.

Cleaning the Leaves

Wipe leaves with a damp cloth every few weeks to remove dust and allow better light absorption.
Avoid using commercial leaf shine products, as they can clog the plant’s natural pores.

6. Repotting Your Calathea Stella

When to Repot?

Every 1–2 years or when roots start to outgrow the pot.
Signs your plant needs repotting:
- Roots growing out of drainage holes.
- Soil drying out too quickly after watering.
- Stunted growth and lack of new leaves.

How to Repot

Choose a pot that’s 1–2 inches larger in diameter than the current one.
Use fresh, well-draining soil to prevent root rot.
Gently remove the plant, shake off excess soil, and place it in the new pot.
Water lightly and keep in a humid environment for the first few days.

7. Common Problems & Solutions

Yellowing Leaves?

Cause: Overwatering or poor drainage.
Solution: Let the soil dry out before watering again and ensure proper drainage.

Brown, Crispy Leaf Edges?

Cause: Low humidity or chemicals in tap water.
Solution: Increase humidity and use distilled or filtered water.

Drooping Leaves?

Cause: Underwatering or sudden temperature changes.
Solution: Water thoroughly and keep the plant in a stable environment.

Pests (Spider Mites, Mealybugs, Aphids)?

Solution: Wipe leaves with insecticidal soap or neem oil. Inspect regularly and isolate affected plants.
