Q. Can you tell me if there is a Master Gardening course near Vienna, VA
The Master Gardener Program is offerred in most counties in the US. It is part of Cooperative Extension and is run by the offices in local counties. Training consists of about 50 hours in the classroom. You are obligated to provide a minimum number of hours each year to remain active. Contact the local office for details and how to apply. In your case do a search on "VA Master Gardener" to find the county office. Zip code will work. Payment of a fee may be required and there are programs for low income applicants.
