Master Gardeners are volunteers trained by the Penn State Extension. Once they complete their training, Master Gardeners help the Extension better serve the home gardening public by answering questions, speaking to groups, working with 4-H horticultural projects, participating in civic beautification, maintaining demonstration gardens, teaching plant sciences and horticulture, maintaining this web site, and in many other ways. Master Gardeners are willing and able to educate individuals and groups in gardening topics such as plant selection, composting, soil improvement, pest control, vegetable and flower gardening, pruning, and more.
