This certificate is awarded to individuals who have completed both the Advanced Green Gardener course and the Green Gardener Recertification course, thereby encouraging Green Gardeners to refresh and update their knowledge and skills related to sustainable landscaping. Unlike the basic Green Gardener courses (Module 1 and 2), the Advanced Green Gardener and Green Gardener Recertification courses offer hands-on training in sustainable landscaping. Thus, this certificate is awarded to Green Gardeners who have added hands-on training to their landscaping experiences.
