TV gardener and chat show host Alan Titchmarsh shot for The Times. Alan is currently embroiled in a row over peat which has split older against younger gardeners. Conservation minded younger gardeners like Alys Fowler are against the use peat compost as it comes from centuries-old bogs and digging it up releases greenhouse gasses and ruins wildlife habitats. However, Titchmarsh says he will carry on using peat until a "perfect substitute" is found.
