Everything it needs
9 essentials at a glance
Watering
Colocasia Esculenta Var.
Antiquorum prefers consistently moist soil, so water it thoroughly when the top inch of soil feels dry. In warmer months, this may mean watering every 2-3 days, while in cooler months, reduce to once a week. 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 partial shade to full sun, ideally receiving 4-6 hours of indirect sunlight daily.
It can tolerate some direct sunlight but may suffer leaf burn if exposed for too long. A location with morning sun and afternoon shade is ideal for optimal growth.
Soil
Colocasia prefers rich, well-draining soil with a pH range of 5.5 to 7.0.
A mixture of potting soil, compost, and perlite or sand can provide the necessary drainage and nutrients. Ensure that the pot has drainage holes to prevent waterlogging.
Humidity
This plant enjoys high humidity levels, ideally between 60-80%.
To increase humidity, consider misting the leaves regularly or placing a humidifier nearby. Signs of low humidity include browning leaf tips and curling leaves.
Temperature
Colocasia Esculenta Var.
Antiquorum thrives in temperatures between 65-85°F (18-29°C). It is hardy in zones 8-11 and can tolerate brief periods of colder temperatures but should be protected from frost. In winter, keep it indoors if temperatures drop below 50°F (10°C).
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 or similar.
Fertilize every 4-6 weeks during the growing season (spring and summer) and reduce frequency in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune dead or yellowing leaves as needed to promote healthy growth and airflow.
Use clean, sharp scissors or pruning shears to avoid disease transmission. Deadheading is not necessary for this plant, but removing spent leaves can enhance its appearance.
Repotting
Repot every 1-2 years or when the plant 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, trim any damaged roots, and place it in fresh soil at the same depth as before.
Propagation
Propagation can be achieved through division or offsets.
In spring, carefully separate the tubers from the main plant, ensuring each has roots attached. Replant them in moist soil at the same depth they were growing before. Alternatively, seeds can be sown in warm, moist conditions, but this method is less common.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or nutrient deficiency.
How to fix it
Check soil moisture levels and reduce watering frequency. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Wilting leaves
Why it happens
Under-watering or low humidity.
How to fix it
Increase watering frequency and mist the plant to raise humidity levels.
Brown leaf tips
Why it happens
Low humidity or inconsistent watering.
How to fix it
Increase humidity through misting or using a humidifier and ensure consistent watering.
Root rot
Why it happens
Poor drainage or over-watering.
How to fix it
Allow the soil to dry out before watering again, and ensure the pot has adequate drainage holes.
Pest infestations (e.g., aphids, spider mites)
Why it happens
High humidity and crowded conditions.
How to fix it
Regularly inspect the plant, and treat infestations with insecticidal soap or neem oil.
Care through the year
Spring
In spring, increase watering as the plant begins to grow actively. Fertilize every 4-6 weeks to support new growth.
Summer
During summer, maintain consistent moisture and provide partial shade during the hottest part of the day to prevent leaf burn.
Fall
In fall, gradually reduce watering as the plant's growth slows. Continue to fertilize until late fall.
Winter
In winter, keep the plant in a warm location, reduce watering, and avoid fertilizing until spring when growth resumes.
Toxicity & Safety
Colocasia Esculenta Var. Antiquorum is toxic to pets and humans if ingested, particularly the raw tubers and leaves. Symptoms of ingestion may include irritation of the mouth and throat, nausea, and vomiting.
