You can get more cuts from dandelion than you can from lettuce. And when you are done harvesting, you just till in the bed. Probably a good idea to plant every three weeks or so, to keep your plantings fresh. I plant by making shallow furrows with a hoe, and then placing seed by hand into furrows at high density. I used overhead irrigation on dandelions, and had no disease.
