Answer: Peppermint roots can really invade a garden and your idea of planting in a container is a good one - it will help control the spread of the plant. Peppermint also spreads through seeds, so be sure to keep the flowers cut off before they have a chance to set seeds. Use a 3-gallon container, make sure it has drainage holes in the bottom, and bury the container into the soil so the rim is just at soil level. Peppermint grows best in full sunshine and will get by with little water (it's one of those drought-tolerant plants). Peppermint is easy to grow and doesn't need to be fertilized on a regular basis. In fact, I don't fertilize mine at all!
