'straw potato' disappointment
This spring I planted 20 red gold seed potatoes the way I always have, in the ground and covered with soil. Later I mulched them with straw. Then I planted 60 seed potatoes of other varieties, in the method I understood to be the "straw method". I dug a trench and placed the seed potatoes in it, covering them with straw until the trench was full. I also shored them up with extra straw as they grew. The red potatoes had a moderate yield -- not heavy, but several good sized tubers per plant. The other plants look huge and healthy, but there's nothing underground except a few dime-sized tubers hugging the roots. It's so disappointing! My only guess as to what happened is that the slugs had easier access to them and ate them all? what else might have caused this, any ideas?
