I’m a first time veg gardener and was wondering how long I have to keep spraying my potatoes with Dithane? There is some blight in the crop but I’ve been removing those plants as far as possible. Will the healthier plants give me bigger potatoes if I keep spraying? I’ve been getting conflicting advice from people at the allotment some of whom have only sprayed three times over the summer.
