Everything it needs
9 essentials at a glance
Watering
Calathea lutea prefers consistently moist soil, so water when the top inch of soil feels dry.
During the growing season (spring and summer), water every 1-2 weeks, ensuring thorough drainage. In fall and winter, reduce watering frequency to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf curling and browning edges.
Light
This plant thrives in bright, indirect light but can tolerate lower light conditions.
Avoid direct sunlight, which can scorch the leaves. Ideally, it should receive 12-14 hours of filtered light daily. If placed near a window, use sheer curtains to diffuse the sunlight.
Soil
Calathea lutea prefers a well-draining, rich potting mix with organic matter.
A pH range of 6.0 to 7.0 is ideal. A recommended potting mix includes peat moss, perlite, and pine bark to ensure good aeration and drainage.
Humidity
This plant thrives in high humidity levels of 50-70%.
To increase humidity, mist the leaves regularly, use a humidity tray, or place a humidifier nearby. Signs of humidity stress include browning leaf tips and curling leaves.
Temperature
Calathea lutea prefers temperatures between 65-80°F (18-27°C) and is sensitive to cold drafts.
It is best suited for hardiness zones 10-12. Avoid exposing the plant to temperatures below 60°F (15°C) as it can lead to stress.
Fertilizing
Use a balanced, water-soluble fertilizer with an NPK ratio of 20-20-20.
Fertilize every 4-6 weeks during the growing season (spring and summer) and reduce to once every 2-3 months in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Calathea lutea as needed to remove any yellow or damaged leaves.
Use clean, sharp scissors or pruning shears to avoid disease. Deadheading is not necessary, but removing spent leaves will encourage new growth.
Repotting
Repot Calathea lutea every 1-2 years or when it becomes root-bound.
Signs that it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot that is 1-2 inches larger in diameter than the current one. Carefully remove the plant, refresh the soil, and replant.
Propagation
Propagation can be done through division.
The best time to propagate is in spring. Carefully remove the plant from its pot, separate the root ball into sections with at least one healthy leaf and root. Replant each section in a suitable potting mix and water thoroughly.
When it's unhappy
Yellow leaves
Why it happens
This can be caused by over-watering or low light conditions.
How to fix it
Adjust watering frequency and ensure the plant receives adequate indirect light.
Brown leaf tips
Why it happens
Brown tips are often a sign of low humidity or underwatering.
How to fix it
Increase humidity levels and ensure consistent watering.
Curling leaves
Why it happens
Curling can occur due to underwatering or sudden temperature changes.
How to fix it
Check soil moisture and maintain stable temperatures away from drafts.
Leaf spots
Why it happens
Leaf spots may indicate fungal infections or water on the leaves during bright light.
How to fix it
Ensure proper air circulation and avoid overhead watering.
Stunted growth
Why it happens
This can be due to nutrient deficiency or being root-bound.
How to fix it
Fertilize appropriately and consider repotting if necessary.
Care through the year
Spring
In spring, increase watering frequency as the plant begins to actively grow. Fertilize every 4-6 weeks and consider repotting if root-bound.
Summer
During summer, maintain consistent moisture and high humidity. Ensure the plant receives bright, indirect light and continue fertilizing every 4-6 weeks.
Fall
In fall, gradually reduce watering as the plant's growth slows. Continue to monitor humidity levels and adjust as needed.
Winter
In winter, water less frequently, allowing the soil to dry out more between waterings. Reduce fertilization to once every 2-3 months.
Toxicity & Safety
Calathea lutea is non-toxic to pets and children. It is safe to have around cats and dogs, with no known symptoms of ingestion.
