Monarch butterfly populations are declining due to loss of habitat and planting milkweeds can help, since the larvae feed on milkweeds. Free milkweed pods are available for pick up this week in Waban.  If interested call Marcia at 617-964-8567.  For info on storage, treatment and planting of milkweed seeds visit http://www.monarchwatch.org/milkweed/prop.htm
