Not long before Christmas, volunteers with Wreaths Across America placed wreaths at about 112,000 gravesites at Arlington National Cemetery.

Saturday, the cemetery needs volunteers to help clean them up.

The cemetery's welcome center will open at 7 a.m. for volunteers; they will be briefed on the cleanup plan shortly before 9 a.m. at the Memorial Amphitheater.

The cleanup should last until about 1 p.m. The cemetery will be closed to vehicles, including those with permanent passes, during that time.

Due to limited parking, the cemetery encourages volunteers to use Metro.

The cleanup will take place regardless of weather, according to an Arlington National Cemetery news release.

Volunteers are encouraged to wear gloves, comfortable shoes and weather-appropriate clothing, and to bring something to collect or hold multiple wreaths, like a broom handle, a rake or a rope with a board tied to one end.
