Planting tomatoes the not-so-traditional way. Just buy some meaty, juicy tomatoes with many seeds in the supermarket and slice them up, about 1/2 an inch thick. We had some cocktail tomatoes left over here, but any will work as long as they’re halfway fresh and juicy. Lay the slices into a pot with good potting soil, giving them some space (or using seperate pots) and cover with about 1/2 an inch of dirt. Water lightly and… wait.
