• Temperature: The optimum temperature ranges between 18 and 28 ° C. The wentii is very sensitive to extreme cold and heat. It should not be exposed to temperatures below 13-15 ºC, as below this range, its growth slows and it can enter a dormant phase. Avoid sudden changes, drafts, and overly dry environments.
• Humidity: Requires high humidity (60-80%)To maintain it, especially indoors, you can group plants, use trays of pebbles and water, use electric humidifiers, or spray the foliage regularly. Be careful not to over-wet the leaves to prevent fungus.

Irrigation and humidity: how to get it right to avoid problems

Irrigation is the most delicate factor in the cultivation of Alocasia wentii. A substrate that is always moist but never waterlogged is the key. to maintain healthy roots and vibrant foliage.

• Frequency: In spring and summer, water 2-3 times per week, always checking that the top layer of the substrate has lost moisture before watering again. In autumn and winter, reduce the frequency to once a week or every 1 days, always checking the condition of the substrate.
• Technique: Use room-temperature water. Water preferably from the base or using a fine-spray watering can, soaking the soil evenly. If you use a saucer under the pot, empty the excess water 20-30 minutes after watering to prevent the roots from being exposed to moisture for long periods of time.
• Water quality: Avoid hard or chlorinated water. You can use rainwater, distilled water, or filtered water to prevent salt buildup in the substrate.

An adequate fertilizer favors the development of large, healthy, shiny leaves, in addition to constant regrowth. If the leaves lose color or appear tiny and limp, it may indicate a nutrient deficiency. Avoid overfertilizing, as this can cause root burn or weak, disproportionate growth.
