Questions about burials

Are graves filled in straight after a funeral or are they left to the next day?

Graves are prepared for burial at least one full day before the funeral and are covered overnight.

The Institute of Cemetery and Crematorium Management (ICCM) guiding principles for burial services state that immediately after the mourners have departed the graveside, the grave shall be entirely backfilled and made tidy. This work is completed on the day of the burial and coffins should not be left uncovered overnight.
