This event began in the 1800's and usually the church chose a Sunday in May or early June for their Decoration Day. During that era, the month of May was usually chosen because flowers were in bloom and could be cut to decorate the graves. Also the weather was mild and the spring planting was finished. The long hot days of work in the fields had yet to arrive.
Traditionally, Decoration Day involved more than just decorating the graves of loved ones. The event included a church service followed by dinner on the ground (picnic) and sometimes a singing. Attendance brought about reunions of families who had loved ones buried in the cemetery. They all came dressed in their Sunday best, walked along the cemetery paths to admire the flowers on graves of their ancestors, and enjoyed the home-made dishes served buffet style on wooden tables.
My family went to Decoration Day at a country church in Tennessee where my great-grandparents and grandparents were buried, along with many other family members. One my earliest memories, believe or not, is one of the outhouses behind the church, which had been built in mid-1800's. I had never seen an outhouse or used one. I don't remember ever seeing a real outhouse anywhere else. The outhouses and the old church are gone now, replaced by a new church. And the tables are gone, too. Once, they made tables for dinner on the ground by nailing a piece of wood vertical on two tree trunks, and then laid planks horizontal on top the vertical supports to make a table.
Although Decoration Day is no longer the social event it was a hundred years ago, it still observed as a day to bring flowers to the cemetery and remember your loved ones.
