Alocasia

Alocasia, also known as Elephant Ear due to its large, dramatic foliage, is a tropical plant that requires very specific care to thrive indoors. Alocasias are known for their striking, arrow- or heart-shaped leaves and unique variegations.

 Light

  • Preferred light: Bright, indirect light.

  • Avoid: Direct sunlight, which can scorch the leaves.

  • Placement: Place your Alocasia near an east or west-facing window for the best results. In lower light, it may grow more slowly, and the leaves may not be as large or vibrant.

Watering

  • Water thoroughly when the top 1-2 inches of soil feel dry. Be sure to let the water drain out of the pot to avoid waterlogging.

  • Water typically, every 5-7 days, but it depends on the season and indoor climate. In winter, reduce watering as the plant enters a dormant phase..

  • Avoid: Overwatering or allowing the plant to sit in water. This can lead to root rot, a common issue with Alocasias.

Temperature and Humidity

  • Alocasia prefers temperatures between 65-80°F. They do not tolerate cold temperatures and should not be exposed to temperatures below 50°F.

  • High humidity is essential for healthy growth. Ideally, maintain humidity levels between 60-80%. If the air is too dry, the plant’s leaves can dry out, turn crispy, or develop brown tips.

    • To increase humidity, use a humidifier, place the plant on a humidity tray, or group plants together.

Soil

  • Alocasias prefer a well-draining, rich, and nutrient  soil mix. A mix designed for tropical plants or a blend of peat, perlite, and pine bark works well.

 Fertilization

  • Fertilize during the growing season (spring and summer), feed every 4-6 weeks with a balanced, water-soluble fertilizer. In fall and winter, when the plant is dormant, you can reduce or stop fertilizing.

  • Type of fertilizer: Use a balanced liquid fertilizer with equal parts of nitrogen (N), phosphorus (P), and potassium (K). You can also use a fertilizer designed for tropical plants.

  • Avoid: Over-fertilizing, as this can cause salt buildup in the soil and burn the roots.

Additional Tips

  • Dormancy: Alocasia tends to go dormant during the cooler months (fall/winter). During this time, growth may slow down, and older leaves may die off. Reduce watering and stop fertilizing during this period.

  • Leaf drooping or curling: This can sometimes happen due to stress, particularly from sudden temperature changes or drought. Make sure the plant is in a stable environment.

  • Pro tip: keep the leaves clean and free of dust
