Just as plants need nutrients, sun and oxygen to grow, Extension Master Gardeners need enthusiastic volunteers to thrive. Community service is at the core of the Master Gardener program in Springfield, MO and each year brings a new opportunity for area plant and garden enthusiasts to take our Master Gardener training and join our family of volunteers.
