The final installment of The Mall at Chestnut Hill’s 2009 Organic Garden Series will take place Saturday, September 12 with “Native Plants.” Hear a presentation on winterizing gardens, and best of all, there will be a tomato tasting and a lecture on how to preserve food (canning, freezing, fermenting) with results from June’s seedlings. Also, there will be an opportunity to purchase from a vegetable and fruit stand. For more information, log on to www.simon.com and click @Your Mall Now!, or call 617-965-3037.
