Remove all lights, wire, tinsel, ornaments, nails, stands and other materials that are not part of the original tree. Also, nonorganic materials aren't good for a compost mixture. Some groups or businesses do not accept flocked trees. Christmas wreaths and swags can be recycled with the trees. Most recyclers ask that all metal and wire be removed.
All nonprofit groups accept trees at least one day on the weekend.
Nonprofit organizations provide this service as a fundraiser for many worthwhile projects and as a community service. Dumping trees after sites are closed creates hardship for the groups having to handle them. Please be considerate.
