Jonathan Bates from Food Forest Farm in Holyoke explains ethics, principles and design process for growing an edible garden oasis at the Agricultural Hall on Sunday, April 6, from 1 to 4 p.m. Mr. Bates grows pest-free fruits from berries and grapes to beach plums, and a variety of greens and vegetables, and he does this without tilling, which means his soil increases in fertility year after year.
