Care Guide:

1. Light:
Alocasia Longiloba Watsoniana thrives in bright, indirect light. Place it near a window with filtered sunlight or in a spot with bright, indirect light indoors. Avoid exposing it to direct sunlight as it can scorch the leaves.

2. Temperature:
This plant prefers warm temperatures between 65-85¬?F (18-29¬?C). Avoid exposing it to temperatures below 60¬?F (15¬?C) as it can suffer damage or slow growth. Protect it from drafts and sudden temperature changes.

3. Humidity:
Alocasia Watsoniana enjoys high humidity levels. It is recommended to place the plant on a tray with pebbles and water or use a humidifier to create a humid microclimate around it. Regular misting of the leaves also helps maintain humidity.

4. Watering:
Keep the soil consistently moist but not waterlogged. Water the plant thoroughly when the top inch of soil feels dry. Ensure proper drainage to prevent waterlogging, as this can lead to root rot. During winter, reduce watering frequency but do not let the soil completely dry out.

5. Soil:
Provide a well-draining, rich potting mix. You can use a mix of peat moss, perlite, and organic compost. Alocasia Watsoniana prefers slightly acidic soil with a pH level between 5.5-6.5.

6. Fertilizer:
During the growing season (spring and summer), feed the plant with a balanced liquid fertilizer every two to three weeks. Dilute the fertilizer to half the recommended strength. Avoid fertilizing during winter when the plant is in a dormant phase.

7. Pruning:
Remove any yellow or damaged leaves promptly to maintain the plant's aesthetics and overall health. You can also trim any leggy or excessively long stems to encourage bushier growth.

8. Propagation:
Alocasia Longiloba Watsoniana can be propagated through division. Carefully separate the rhizomes during spring or early summer, ensuring each division has healthy roots and shoots. Plant the divisions in separate pots with well-draining soil, keeping them slightly moist until they establish.

9. Pests and Diseases:
Watch out for common pests like spider mites, aphids, and mealybugs. Regularly inspect the plant for any signs of infestation, and if found, treat with an appropriate insecticide or wipe the leaves with a mild soap solution. Avoid overwatering to prevent root rot.

10. Repotting:
Repot the Alocasia Watsoniana when it outgrows its current pot, usually every one to two years. Choose a slightly larger pot and use fresh potting mix. Spring is the ideal time for repotting.

By following these care guidelines, your Alocasia Longiloba Watsoniana will thrive and become a stunning focal point in your indoor plant collection. Enjoy its lush foliage and unique beauty while creating a tropical atmosphere in your home.
