We have some vendors who are USDA Organic or follow organic practices and are otherwise certified (via Certified Naturally Grown); other vendors use conventional growing methods. All our producers use their own products at home and are mindful of fertilizers and pest-control methods they introduce. If you have a preference for growing methods, please ask at the market information tent in Saratoga and we will help to find vendors who meet your criteria. In Clifton Park, just inquire with the vendors.
