My family cemeteries are 40 miles away. I leave flowers early in the week of Memorial Day & pick them up before June 15. The man who mows one cemetery told me the cemetery doesn’t get flowers compared to when he started 18 years ago. I make my own pots with plastic flowers & a few inches of cement in the bottom. In 4-5 years they get replaced with new as they don’t look so good anymore. We also “tidy up” a few extended family graves with a weed whip & spray but don’t decorate. Anytime I’m in the area, I stop at my parents grave. Their graves are just inside the fence so it’s easy to do.
