John Clark – A former Chartered Town Planner, he was the Garden History Society’s Conservation Officer for the South West Region for over 9 years and is the Conservation Officer for the Devon Gardens Trust.  He has considerable knowledge of  designed landscapes and offers specialist advice on historic parks and garden and their setting. Over the years, John has advised local planning authorities on a number of planning applications about development proposals  affecting walled kitchen gardens. The advice is generally that walled kitchen gardens should not be regarded as suitable sites for new houses but, in the few occasions where development is appropriate,  the design should reflect the traditional buildings found in walled gardens.

Chris & Karen Cronin – They are the owners of the now flourishing Walled Kitchen Gardens at Croome Court in Worcestershire. They bought the then derelict kitchen gardens in June 2000 when the Estate was under the mixed ownership of property developers and the National Trust.

Current objectives include a future restored Tomato House and further extensions to the ‘sustainable’ vegetable planting. In addition they are working on restoring the old ‘Orchid House’ which will be a significant feature once it takes its place again within the landscape of the Kitchen Gardens.
