Cornell University Cooperative Extension of Cattaraugus County will present a three-week Organic Gardening Series on Thursdays from May 22 to June 5, 6–8 p.m., at the Olean Public Library, 134 North 2nd St., Olean. The sessions are free and open to the public.

The sessions will focus primarily on organic vegetable gardening, but the principles can be applied to all of your home plantings. Learn about organic fertilizers and soil conditioners, and organic methods of insect and disease control.  Sessions will be presented by Mark Holt, Agriculture-Horticulture Community Educator, and Cornell Cooperative Extension’s Master Gardener Volunteers.

Preregistration is required. To register, please call the Olean Public Library at 716) 372-0200.
