Comprehensive Care Guide for Alocasia scalprum

Light: Thrives in bright, indirect light. Avoid direct sunlight, which can scorch the leaves.

Watering: Water when the top 1-2 cm of soil feels dry. Keep the soil evenly moist but never waterlogged.

Humidity: Alocasia scalprum prefers high humidity levels above 60%. Use a humidifier, group with other tropical plants, or place near a pebble tray to increase moisture in the air.

Temperature: Ideal temperatures range from 18°C to 27°C. Protect the plant from sudden temperature fluctuations and cold drafts.

Soil: Use a well-draining mix of peat, perlite, and orchid bark to prevent root rot while retaining adequate moisture.

Repotting and Pot Choice: Repot every 1-2 years or when root-bound. Choose shallow pots with good drainage to suit its tuberous roots.

Fertilizing: Apply a balanced liquid fertilizer once a month during active growth. Avoid over-fertilizing to prevent leaf damage.

Propagation: Propagate by dividing rhizomes during repotting. Ensure each division has a growth point and roots before planting in moist soil.

Hydroponics: Alocasia scalprum adapts well to semi-hydroponic setups. Use a nutrient-rich solution and ensure adequate aeration around the roots.

Pruning: Remove yellowing or damaged leaves regularly to maintain a neat appearance and encourage healthy growth.

Placement: Place the plant in well-lit areas like near east-facing windows or under grow lights. Avoid direct sunlight and ensure consistent conditions.
