How long does it take for banyan to heal with a curved saw?

More than half a year. Banyan is a big tree, with a height of 15-25m, DBH 50cm and a broad crown. Old trees usually have rusty brown air roots. Banyan has strong adaptability, likes loose and fertile acidic soil, can grow in barren sandy soil, and leaves turn yellow in alkaline soil. Not drought-resistant, more water-resistant and wet-resistant, and short-term waterlogging will not rot the roots. Apply the healing agent to the curved incision wound and wrap it with a film. It takes more than half a year for the wound to heal perfectly.
