Alocasia ‘Red Secret’ - Care Practices
Light: Bright indirect light. Leaves are sensitive and can burn easily from direct light or hot dry temperatures. Alocasias will move their leaves towards the light in undesirable low light levels.
Water: The thicker leaves of this alocasia indicate that it prefers to dry out ever so slightly before watering. The soil should be evenly damp after watering but not soaking.
Humidity: Prefers humidity between 55% – 75%. A lower relative humidity (RH) will cause the leaf edges to crisp up!
Temperature: Average from 18°C to 24°C
Fertilizer: Follow a monthly fertilizing schedule when the plant is actively growing. In most cases, this is in the spring and summer. Use a balanced fertilizer – this means a ratio of NPK that is all the same. Ex: 10-10-10.
Soil: Use a well-draining, high organic matter soil mix.
Propagation: Division or by separating corms
Repotting: Can be done every 12-18 months. Choose a pot that is 5cm larger in diameter than the original pot.
Cleaning Tip: Gently wipe down with a damp cloth to remove dust. Remove yellowing leaves right away.
Toxicity: Toxic. Keep plants away from children and pets.
Red Secret - Common Problems
My Red Secret is still looking small...
Fear not! Alocasia plants are slow growers, but in time can grow to 1m tall with leaves up to 24cm long.
Why are my Red Secret’s leaves yellow?
This may be due to too much direct sunlight, which can cause scorching or color fading.
My Red Secret looks burnt!
This could also be a sign of too much direct sunlight, or a result of using fertilizer during colder winter months, as too much salt can accumulate in the soil and burn the leaves.
Signs of Overwatering
Soil becomes oversaturated.
Check for mealy bugs, scale, and spider mites.
What is the best environment for this plant?
Alocasias love a tropical climate, so sit near a humidifier and/or other plants (out of direct sun) for the best results.
