Choose a flower bed location in the direct sun or partial sun.
Prepare the soil by adding 2 to 4 inches of composted manure per square foot of bedding soil. Add 1/2 tablespoon of 16-16-18 fertilizer per square foot and work the manure and fertilizer into the top 6 inches of soil.
Plant one mint plant every 2 feet. Dig a shallow hole, deep enough to cover the root with a small shovel. Cover the base of the mint loosely with the shovel.
Dampen the soil lightly and water the bed once a week. Don't overwater mint as this can make the roots moldy.
Harvest mint every two to three weeks by clipping the branches down several inches using sharp garden scissors. Cut the the stems down to 1 inch above the soil at the end of the growing season.
