When it comes to gardening, it doesn't get easier or cheaper than growing Basil. A dollar to a dollar fifty for seeds, a nice long container or miscellaneous pots, potting soil and water. You literally just need to sprinkle the seeds, add a thin layer of soil and water. Voila! You're done.
No worrying if you've planted the seeds too deep or that a squirrel is going to dig them up for a snack like sunflower seeds. Our basil pot is full of tiny plants and thriving. I'm already looking forward to pesto.
