Everything it needs
9 essentials at a glance
Watering
Leucocasia gigantea prefers consistently moist soil, requiring watering every 1-2 weeks depending on the season.
In warmer months, increase frequency to weekly, ensuring the top inch of soil remains damp but not soggy. Signs of over-watering include yellowing leaves and root rot, while under-watering can cause wilting and browning leaf edges.
Light
This plant thrives in bright, indirect light but can tolerate partial shade.
Ideally, it should receive 4-6 hours of filtered sunlight daily. Direct sunlight can scorch the leaves, so placing it near a window with sheer curtains is recommended.
Soil
Leucocasia gigantea prefers well-draining, rich soil with a pH of 5.5 to 7.0.
A mix of potting soil, peat moss, and perlite is ideal for drainage and moisture retention. Ensure the pot has drainage holes to prevent waterlogging.
Humidity
This plant enjoys high humidity levels of 60% or more.
To increase humidity, consider using a humidifier, placing a pebble tray with water beneath the pot, or misting the leaves regularly. Signs of low humidity include brown leaf tips and curling leaves.
Temperature
Leucocasia gigantea thrives in temperatures between 65-85°F (18-29°C) and is hardy in zones 9-11.
It is sensitive to cold, so protect it from temperatures below 50°F (10°C) and avoid drafts during winter.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 10-10-10 or similar, applying every 4-6 weeks during the growing season (spring and summer).
Reduce feeding in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune dead or damaged leaves as needed to encourage new growth and maintain appearance.
Use clean, sharp scissors or pruning shears. Deadheading is not necessary for this plant, but removing spent leaves will enhance its overall health.
Repotting
Repot Leucocasia gigantea every 1-2 years or when it outgrows its pot, indicated by roots growing out of the drainage holes.
Choose a pot 1-2 inches larger in diameter. Carefully remove the plant, refresh the soil, and replant, ensuring the tubers are not buried too deeply.
Propagation
Propagation can be done through division or offsets.
To divide, carefully remove the plant from its pot and separate the tubers, ensuring each has roots. Replant them in individual pots with fresh soil. The best time to propagate is in spring when the plant is actively growing.

Care through the year
Spring
In spring, increase watering as the plant begins to grow actively. Fertilize every 4-6 weeks to promote healthy growth.
Summer
During summer, ensure the plant receives adequate moisture and humidity. Monitor for pests and adjust watering frequency as needed.
Fall
In fall, reduce watering as growth slows down. Continue to fertilize until late fall, then stop for winter.
Winter
In winter, keep the plant in a warm location away from drafts. Water less frequently, allowing the soil to dry out slightly between waterings.
Toxicity & Safety
Leucocasia gigantea is toxic to pets and humans if ingested. The plant contains calcium oxalate crystals, which can cause irritation, swelling, and pain in the mouth and throat. Symptoms include difficulty swallowing, vomiting, and stomach pain.
