To get a head start

on spring crops, sow seeds in a cold frame and use compost as a natural ‘heating pad’. Compost generates heat in the initial stages of breaking down and can be used to provide warmth for seedlings. Place fresh grass clippings into a polystyrene tray. Add a layer of seed-raising mix and sow your seeds as per the instructions. Place a sheet of glass or sturdy plastic over the tray, cover with newspaper and place the tray in your cold frame or a warm, sunny spot. Remove the covering once the seeds have germinated.
