• The most suitable time for applying manures and fertilizers to mango trees is during the post-monsoon period, which falls primarily in October, but can start in late September. This timing is ideal because:

Flower Initiation: Applying nutrients before the flowering season, which usually begins in December, helps promote flower initiation and fruit set.
