This means you must remove any items of sentimental value from the graves of your loved ones. We cannot be responsible for items left on graves. We also ask that you please keep the following guidelines in mind throughout the year: Families are welcome to place fresh flowers on the graves of their loved ones at any time. Artificial flowers and wreaths are permitted during the month of November through March. Flags are permitted three days before and after Memorial Day, July 4th, and Veterans Day. Your observance of this policy is greatly appreciated!
