William Sinclair has come out top in a Which? Gardening container compost trial. New Horizon scored 80/100 while Westland multipurpose with added John Innes scored 80/100. Scotts Miracle-Gro Organic Choice all purpose peat free compost scored 28 and was least recommended in the test of 17 composts.
In another Which? Gardening test, to compare taste and nutrient content of three organic and non-organic crops - potatoes, calabrese and tomatoes –the gardening magazine's testers found "little, if any, nutritional or taste benefits to growing organically".
But Dr Margi Lennartsson, head of programmes at Garden Organic said:
"I think it's important to note that these were small scale trials that whilst looking at the nutrient content and taste didn’t take into account the higher levels of pesticides, herbicides and insecticides that non-organic produce might be exposed to. People that grow organic produce state that avoiding harmful chemicals is one of their main motivations for using organic methods and any trial that looks at the health benefits of organic food, ought to also consider this."
