Neighborhood plant clinics will be held each Saturday, Aug. 19 through Oct. 14, 10 a.m. to 2 p.m. at seven Fairfax County public library locations and at two public libraries in Montgomery County.

Trained volunteers, representing 32 federated garden clubs in the metropolitan area, will serve as plant consultants to answer questions from gardeners concerning problems with indoor and outdoor plants.

Sponsored by the National Capital Area Federation of Garden Clubs and the Cooperative Extension Services of the University of Maryland and Virginia Polytechnic Institute, the plant clincs are a free community service.

Gardeners may visit the plant clinic in their immediate area for up-to-date information concerning plant and pest problems. Take along samples of problem plants for identification and diagnosis.

In Fairfax County, clinics will be held at George Mason Regional Library, Annandale; Kings Park Library, Burke; Central Library, Fairfax City; Dolley Madison Library, McLean; Reston Regional Library, Restion; Richard Byrd Library. Springfield, and Patrick Henry Library Vienna.

In Montgomery County the clinics will be held at Davis Library, Bethesda, and White Oak Library, Silver Spring.

For plant identification, take along a twig or stem, leaf and flower or seed.

For weed indentification, take the entire plant.

For diagnosis, take a sample containing both good plant material and sick plant material, such as an 8-inch square of lawn showing one-half live grass and one-half dead grass; or a 6 to 18-inch branch of healthy plant material with foliage, and the same size branch showing sick plant with foliage, if possible.

Take insects in a clear, plastic bottle.
