Common Milkweed Pod Collection

  • Monarch on milkweed in July

2021 Pod Collection: September 15 - October 30

 NH Fish & Game and UNH Cooperative Extension are calling on New Hampshire residents for milkweed pod collections!

The seeds from the milkweed pods will be sown by NH Department of Transportation into conservation corridors, designated areas along highways that are planted with native perennials to benefit pollinators.

While milkweed serves as a food source for many other species of pollinator, it is the exclusive host plant on which Monarch butterflies lay their eggs, and on which caterpillars feed. The disappearance of milkweed across the US has contributed to an 80% decline in the eastern Monarch butterfly population over the last 20 years. State and federal agencies, conservation organizations, and others are working diligently to increase the volume of milkweed on the landscape, and individuals can help by contributing to this important resource collection effort.

Collecting Milkweed Pods

  • Only collect the pods when they are dry and grey/brown. If the center seam pops with gentle pressure, they can be harvested. 
  • Store the pods in paper bags; plastic bags will collect unwanted moisture. 
  • Write the date and county collected on the bag. 
  • Keep the pods in a cool, dry place until you deliver them to the collection site. 
  • Leave some pods (25%) on the plants to also allow for natural dispersal.
