I might need to replant lettuce for the 4th time, but look at how well my potatoes are growing! I start these by sitting sprouting red potatoes (or potato starts when they are available and cheap) on an inch of potting soil and then barely covering them. As the grow I add more soil to almost cover the foliage. They grow so rapidly they need more soil every day or two. Then in 10-12 weeks, if I am blessed, there will be a pot of potatoes. Since I almost always use potatoes that would otherwise go to compost, it isn't traumatic if the crop fails. It works really well though, just do not overwater.
And look at this! Last spring I bought a bag of potato starts and, not knowing what else to do with the extras, I stuck them in the ground. They didn't grow, so oh well. But now here they are growing away. I hope they make some potatoes!
