Everything it needs
9 essentials at a glance
Watering
Water Maranta arundinacea when the top inch of soil feels dry to the touch, typically every 1-2 weeks.
In the growing season (spring and summer), increase frequency to once a week, ensuring the pot has good drainage to prevent root rot. Signs of over-watering include yellowing leaves and mushy stems, while under-watering may cause leaf curling and browning edges.
Light
Maranta arundinacea thrives in bright, indirect light but can tolerate partial shade.
Avoid direct sunlight, which can scorch the leaves. Ideally, it should receive 12-14 hours of light per day, and it can adapt to lower light conditions, though growth may slow.
Soil
This plant prefers a well-draining potting mix that retains some moisture, with a pH range of 6.0 to 7.0.
A recommended mix includes peat moss, perlite, and orchid bark to ensure proper drainage while retaining some moisture.
Humidity
Maranta arundinacea enjoys high humidity levels of 50-70%.
To increase humidity, consider using a humidifier, placing a tray of water with pebbles beneath the pot, or misting the leaves regularly. Signs of low humidity stress include browning leaf tips and curling leaves.
Temperature
The ideal temperature range for Maranta arundinacea is 65-80°F (18-27°C).
It is not frost-tolerant and prefers temperatures above 60°F (15°C). This plant is best suited for USDA hardiness zones 10-12, as it cannot withstand cold temperatures.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 every 4-6 weeks during the growing season.
Reduce feeding in fall and winter when the plant's growth slows. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Maranta arundinacea in spring to remove any dead or yellowing leaves and to encourage bushier growth.
Use clean, sharp scissors or pruning shears to make clean cuts. Deadheading is not necessary, but removing spent leaves can improve the plant's appearance.
Repotting
Repot Maranta arundinacea every 1-2 years or when it becomes root-bound, indicated by roots growing out of the drainage holes.
Choose a pot that is 1-2 inches larger in diameter. Carefully remove the plant from its pot, loosen the roots, and place it in fresh potting mix. Water thoroughly after repotting.
Propagation
Propagation can be done through division or stem cuttings.
For division, carefully separate the rhizomes during repotting, ensuring each section has roots. For stem cuttings, take 4-6 inch cuttings with a few leaves, place them in water or moist soil, and keep them warm and humid until roots develop. The best time for propagation is in spring.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or low light conditions.
How to fix it
Adjust watering schedule to allow the soil to dry out slightly between waterings and move the plant to a brighter location.
Browning leaf tips
Why it happens
Low humidity levels.
How to fix it
Increase humidity by misting the leaves, using a pebble tray, or placing a humidifier nearby.
Curling leaves
Why it happens
Under-watering or sudden temperature changes.
How to fix it
Check soil moisture and water if dry, and ensure the plant is in a stable temperature environment away from drafts.
Leaf drop
Why it happens
Stress from over-watering or sudden environmental changes.
How to fix it
Allow the soil to dry out if over-watered and provide a stable environment with consistent light and temperature.
Pests (e.g., spider mites, aphids)
Why it happens
Dry air and poor plant health can attract pests.
How to fix it
Increase humidity and inspect regularly, treating infestations with insecticidal soap or neem oil.
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 watering and humidity levels, ensuring the plant receives bright, indirect light. Monitor for pests due to warmer conditions.
Fall
In fall, gradually reduce watering as growth slows. Continue to fertilize until late fall, and prepare the plant for lower light conditions in winter.
Winter
In winter, reduce watering frequency and stop fertilizing. Keep the plant in a warm area with adequate light, and monitor humidity to prevent stress.
Toxicity & Safety
Maranta arundinacea is non-toxic to pets (cats and dogs) and children, making it a safe choice for households. No parts of the plant are known to cause harm if ingested.
