Orthodox people should realise that the main purpose of visiting the cemetery is a remembrance of the deceased person. The commemoration of the deceased to the cemetery should not be done through eating any food. Remember the food at the burial site does not recommend the Orthodox Church. Most importantly, what should a Christian pray for the dead. Those who do not know certain prayers for the dead are allowed to simply impose the sign of the cross and his words to ask God's forgiveness for the sins of the deceased.
You need to understand also that at the cemetery, a Christian should behave reverently. We cannot allow foul language, the chant of spirits. All of this is a desecration of the memory of the deceased.
Every Christian needs to monitor the cleanliness of the graves of deceased relatives and friends. So, the cemetery can be clean, to restore order at the grave. This is one of the duties of a Christian towards the deceased. Thus, it is impossible to litter on the graves. It is not recommended to leave any food on the graves, because the dead do not need material food. Sometimes it happens that the abandoned food eat up dogs.
An Orthodox Christian can lay fresh flowers on the grave of the deceased, and also put a burning candle in memory of the deceased. Candle can be left at the cemetery.
Leaving the place of burial, it is necessary to re-impose the sign of the cross with a prayer for the forgiveness of sins of the deceased. Worth a look, all the debris removed, if anything needed improvement, it should be done, but nothing more to leave the graveyard.
Thus, it appears that the main goal of a Christian parish to the place of burial is remembrance in prayer the deceased and cleaning the grave for podderjaniya purity.
