Caring for Alocasia lauterbachiana
With the right care, Alocasia lauterbachiana will thrive and stand out in your indoor garden. Here’s how to keep it healthy:
Light Requirements

Prefers bright, indirect light. Aim for 8–10 hours of filtered sunlight daily.
Avoid direct sunlight, which can scorch the leaves. Place near a north or east-facing window.

Soil and Potting Mix

Use well-draining, slightly acidic soil.
A mix of potting soil, orchid bark, perlite, and coconut coir ensures proper moisture balance and prevents root rot.

Watering Guidelines

Allow the top 75% of soil to dry out before watering.
Overwatering can lead to root rot. Water thoroughly, allowing excess water to drain completely.

Fertilization Needs

Feed monthly during spring and summer with a balanced liquid fertilizer diluted to half strength.

Humidity and Temperature

Thrives in high humidity (60–70%). Use a humidifier or place a shallow dish of water nearby if your home is dry.
Optimal temperature is between 18°C and 27°C. Keep away from drafts or heating vents to avoid stress.

Potting and Container Selection

Repot every 1–2 years as needed.
Use a slightly larger pot to avoid excess soil, which retains too much moisture.
Choose a pot with drainage holes to prevent waterlogging. Terracotta pots provide extra breathability for the roots.

Propagation
Propagate Alocasia lauterbachiana through division during repotting, ideally in spring or early summer:

Gently remove the plant from its pot.
Separate a section of the rhizome with at least one leaf and healthy roots.
Plant in fresh, well-draining soil and water lightly.
Keep in a warm, humid spot to help it establish.
