The many culinary uses for mint make this herb a common resident in herb gardens. From cooking to personal care products, mint makes itself useful in a variety of ways. Because mint spreads so aggressively, gardeners often grow it in containers to keep it from taking over a growing area. Propagate new mint plants by taking cuttings from an existing plant. Mint grows readily from cuttings you root in a glass of water.
Find a healthy stem with leaves. Cut off a 3-inch-long section with the scissors
Fill the glass with cool water.
Remove any leaves from the bottom inch of the stem and discard them.
Insert the stem into the water and place the glass in a warm location out of direct sunlight.
Replenish the water in the glass if it begins to evaporate over the next week while the cutting roots.
Fill the planting container about three-quarters full of potting soil.
Remove the cutting from the water when the roots become 1/2 inch long. Plant the cutting in the container and add additional soil to the container to fill it to the top.
Water the soil lightly to saturate it. Place the container in a location that receives about six hours of sun each day. Keep the soil evenly moist while the cutting acclimates to the container.
Plant the new mint plant outside in the spring.
