Duan Gao or ninth month (August) is the month for celebrating Boon Khao Pradub Din. The tradition is a ritual to pay homage and respect to the earth and soil for providing all sources of livelihood. Traditionally food and meals would be buried in the soil and earth. But in modern times it has been changed to burying fertilizers and nutrients in the soil instead. In several communities the ritual is practiced by the placement of food and deserts under large trees. Belief is that the spirits of deceased loved ones will be released to roam freely during the ninth month and that they will receive the food placed in the ground or under large trees.
