Ways To Help Your Community Practice Sustainable Yard Care? Schedule a Master Gardener to speak to your community about sustainable yard care practices. Use this sample Master Gardener presentation, if you can’t schedule a representative to give the talk. Use this sample flyer to advertise the Master Gardener talk. Create a demonstration rain garden for your community. Consider a voluntary “recommended” landscaper program, such as the one Charlestown created. Promote RIDEM’s Self-Certification Checklist for “Green Landscaping Certification.” Publicize stormwater-friendly lawn care tips regularly.
