I recently tried Ruth Stout’s potato planting method using straw mulching. Basically you place a seed potato on the ground, cover with straw and wait. Our straw mulching has been quite successful with other vegetables, so when some store bought potatoes started getting roots on the shelf, I put them in the vegetable garden and covered them with about 200mm of straw.
Lo and behold about 2 weeks later, potato plants! (okay, no potatoes yet, but its a start…)
