What should we do with old flowers and offerings (nirmālya)?

never throw them in the dustbin; return them to nature — garden soil, a tree’s roots or clean flowing water.

Flowers, leaves and garlands that have been offered to God are called nirmālya. They are treated with respect because they have been part of worship. Remove them each morning (or when they wilt) before offering fresh ones.

Traditionally nirmālya was placed in a river or pond. Today, with polluted rivers, many temples and families prefer to put it in a garden pit, under a tulasī or peepal tree, or in a compost bin set aside for the purpose. This is fully in keeping with the spirit of the tradition, which is to let the offering return to the earth respectfully. Avoid plastic bags in rivers.

Old coconut, fruit and sweets that were offered should be eaten as prasāda or shared, not thrown away. Ash from incense and old wicks can go into the soil as well.
