Caring for a betel nut (supari) plant involves some specific considerations. Here’s a brief guide to its maintenance:

1. Sunlight: Betel nut palms thrive in full sunlight. Ensure your plant receives ample sunlight, preferably 6-8 hours a day.
2. Soil: Provide well-draining soil with a slightly acidic to neutral pH. A mix of loam and sand works well. Good drainage is crucial to prevent waterlogged conditions.
3. Watering: Betel nut palms prefer consistently moist soil. Water regularly, especially during dry periods. However, avoid overwatering, as waterlogged conditions can lead to root rot.
4. Temperature: Betel nut palms prefer warm and humid conditions. They are sensitive to cold temperatures, so if you’re growing them in a cooler climate, consider providing protection during colder seasons.
5. Fertilizing: Use a balanced, slow-release fertilizer during the growing season (spring and summer). Follow the recommended dosage on the fertilizer packaging.
6. Pruning: Regular pruning is essential to remove dead or damaged fronds and promote healthy growth. Be cautious not to over-prune, as this can stress the plant.
7. Pest Control: Keep an eye out for pests like mites, scale insects, or caterpillars. Use natural or chemical methods to control pest infestations.
8. Support: As the betel nut palm grows, it may need support to prevent the trunk from bending or breaking. Stake the plant if necessary.
9. Harvesting: Betel nut palms produce betel nuts, which are typically harvested when the fruit clusters mature. However, note that regular consumption of betel nuts has health risks, so be mindful of that aspect.

Remember that the specific care requirements can vary depending on the growing conditions and the age of the plant. Regular observation and adjustments to the care routine will contribute to the well-being of your betel nut plant.
