Alocasia Robusta Care
Alocasia Robusta plants grow best in high humidity. To increase the humidity around a houseplant, place the plant on a tray filled with pebbles and water. Be sure the plant is sitting on the pebbles and not in the water. You can also increase the humidity by placing a small humidifier near the plant or grouping plants together.
Your Alocasia Robusta will thrive in a spot with bright, indirect, filtered light. Never allow this plant to stand in the direct sunlight the leaves will burn. It can survive in medium light, but avoid a dark corner.
Use an organic well-aerated loose soil that contains a good amount of peat moss. If the soil seems a little heavy, add some builder's sand or perlite.
Your Alocasia Robusta enjoys the warmth, preferably between 65-85 degrees, so maintain indoor temperatures above 60 degrees. Avoid cold drafts and sudden temperature changes.
Maintain a regular watering schedule and keep the soil of your Alocasia Robusta moist, but not wet or saturated. This is not a drought-tolerant indoor plant, but it is relatively forgiving if you forget to water it from time to time. Extended periods of dryness can result in brown leaf tips or edges. Root rot will occur if the soil is kept too wet.
For best results, use a general houseplant fertilizer every four weeks during the spring and summer. No fertilizer is necessary during the winter months when plant growth naturally slows. Only apply fertilizer to damp soil–never dry, as it can burn the roots.
