On Wednesday, April 6, from 7 to 9 p.m. at the Scarborough Public Library, Scarborough gardener, local-foods activist and writer Roger Doiron will teach a workshop on organic gardening as part of a statewide program sponsored by the Maine Organic Farmers and Gardeners Association.

The workshops are open to the public and to people of all skill and experience levels. They are designed to provide gardeners with essential skills and knowledge needed to make a transition from conventional to organic gardening.

Participants will acquire an understanding of the basics of soil science, and how to enrich soil to produce healthy, high yielding plants; composting methods; the principles of crop rotation, and how to incorporate green manures and manage nutrients in the garden; the difference between cultivated plants and weeds, and basic weed control strategies; and common insect pests and methods of natural insect control.

A registration fee of $5 will be collected at the door to help cover the cost of handouts.
