Wortley Hall Walled Garden is certified with the Soil Association, GB-ORG-05. Our producer licence number is G9343. Conversion to organic status only took two years, which recognised that the garden had not been cultivated for a number of decades. The soil is a deep clay loam, so the challenge is to maintain its high fertility and good structure...and get on top of the weeds. Illustrated below are some of the strategies we have employed.
