Peppermint is a delicious, robust herb used in many recipes and products. It is easy to grow in any region. Peppermint is simple to process and is prolific in nature. This ground covering plant makes a beautiful and aromatic addition to your collection of herbs. Because of their encroaching nature, many gardeners grow mint-type herbs in containers to keep them in check. Left to their own devices, peppermint plants may take over your entire garden.
Peppermint does best in rich, moist soil. Use a heavy loam that will remain moist for a long period after watering.
Peppermint sends out shoots to cover the ground and spread. It grows quite large if left alone. Plants need some space to grow healthy leaves. Place each plant at least 1½ to 2 feet apart.
Peppermint is a very tall plant, reaching heights of 3 feet. Constant pruning to harvest the leaves will keep its height in check in a container. Planted in a garden soil, it may take over. Place borders around any area containing mint plants so they do not spread beyond your desired spaces.
Peppermint is prone to rust and mildew. Plants should not "sit" in water. Water your plants until the ground around them is moist. Avoid getting the leaves, especially the undersides, wet, and do not water late in the day when the plant cannot dry off before sunset.
Peppermint plants love sunlight. Put them in areas with full sunlight whenever possible. They will grow in partial shade as long as it has a exposure to the sun for a good amount of time during the day. If your plants are long, thin, and "leggy," they are not getting enough light.
Because peppermint is a hybrid by nature, it does not produce seed. It spreads on its own very well, however, and is perennial so yearly planting is not usually necessary. Mulch plants well for the winter in cold climates and they will resurface in the spring. To spread the plant, take a cutting and place it over a cup of water with the end in the liquid. It will root and you can plant a new, separate plant with that cutting.
Keep the area around the plant well-covered with mulch to prevent water splashes on the underside of leaves, and prevent mildew and rust. Mulch will also keep the surrounding area moist without holding water next to the plant.
