Since 1989, I've been a Master Gardener. This wonderful organization, sponsored by State Universities throughout the United states offers a training program, extensive literature and onhand experience in all areas of home gardening.
Master Gardeners "pay back" their training by serving in Plant Clinics that advise and educate the public. It has been a very interesting and rewarding experience.
If you, too, are interested in becoming a Master Gardener, here's a place to visit for more information.
