The Warwick Valley Gardeners will hold a free public meeting on Tues., Apr. 16 at 7 p.m. at the Good Shepherd Lutheran Church, located at 95 Kings Hwy. in Warwick. The discussion at the meeting will be led by Jennifer Briller Esty and will focus on permaculture, which is a planning tool used to evaluate land, how it is used, what it needs, what it can provide, and how it can continue to be used into the future. Esty will introduce the basics of permaculture and allow participants to explore the concepts as applied to a particular piece of land.
