Assam Dholu bamboo is an organic, breathing material. To prevent cracking:
- Keep the flute away from direct sunlight, extreme heat, and sudden air-conditioning drafts.
- After playing, use a soft cotton swab to wipe away internal moisture.
- Lightly oil the inside of the flute every 2-3 months using a few drops of pure mustard or walnut oil to maintain the bamboo's natural moisture balance.
