About Us

Master Gardeners are community volunteers trained by Rutgers experts in sustainable gardening and environmental principles.

  • Sound gardening techniques - plant selection; disease, insect and weed control
  • Integrated Pest Management
  • Composting
  • Creative methods to conserve ​natural resources
  • Community interaction

Master Gardener interns are required to volunteer 60 hours of service to Rutgers Cooperative Extension of Middlesex County before achieving certification. Once graduated a certified Master Gardener must volunteer 25 hours of service each year, to remain in good standing. Examples of volunteer service are:

  • Answering gardening questions on the Gardeners Helpline
  • Conducting composting and recycling lectures/demonstrations
  • Community beautification and demonstration garden maintenance
  • Lecturing on a variety of gardening topics
  • Assisting with community events such as the Middlesex County Fair

Participants become certified Master Gardeners after they have satisfactorily completed the training program and have fulfilled their volunteer service commitment.
