Stewart has teamed up with broadcaster and GYO specialist Pippa Greenwood to help consumers improve their understanding of growing fruit and vegetables at home and support retailers in this increasingly popular market sector.
The three-year partnership, announced at Glee 2011, covers a wide range of joint promotional and educational initiatives.
As well as appearing on the Stewart website, Ms Greenwood will attend promotional events and take part in a GYO training road show for consumers and trade customers.
