Hello October, your potatoes are ready when they have flowered (but sometomes they don't flower) and the shaws start to die down. Roughly, this is about 13 weeks after planting for earlies and 18 weeks for maincrops. It's not an exact science, so round about those times have a wee dig about under the shaws amd see what's there. If it's too soon, give it another week or two and try again. Hope you get a good crop.
