Make a radish dash so it’s safe to nosh

Why do my radishes come out all woody and inedible? Maureen, Bristol DAVID: Radishes should be sown little and often throughout the summer for a regular supply. Small radish varieties will quickly lose their crisp texture if left in the ground too long. Make sure you are harvesting while they are still young to avoid that woody texture – they are usually ready around four weeks after sowing.
