The Kaplen JCC on the Palisades has opened registration for its 22-week CSA — a partnership with a local farm that provides members who buy shares in advance to enjoy locally grown, certified organic produce. The season runs from June 12 to November 6. Full shares average eight to 10 vegetable varieties, competitively priced for less than $24 a week. To launch the season, Ken Fruehstorfer and Maryellen Driscoll of FreeBird Farm in Palantine Bridge, N.Y., above, will be at the JCC in Tenafly on Sunday, April 29, at 1 p.m. Maryellen will lead a veggie stir-fry demo and tasting for adults, while Ken and his children will hold a planting demo for children. Those who signs up as a Community Supported Agriculture member on or by April 29, can attend for $5 per adult; otherwise it costs $10 per adult. There is no charge for children. Registration deadline is May 23. Go to www.jccotp.org or email Marilyn Yeshua at email@example.com.
