Mint Plant Propagation

Mint plants are started from seed. Get an early start planting them indoors as a houseplant. Or, directly sow seeds into your garden in the spring. Space seedlings or thin plants to 12″ to 18″ apart.

Established plants are prolific propagators, producing suckers in the second and following years. They can also be grown from cuttings.

How to Grow Mint Plants

Planting and Soil Needs

Mint plants are simply too easy to grow. If unchecked, these invasive plants rapidly spread their roots and overcrowd other plants.

The plants thrive in full sun to partial shade. They will do well in average soils. With a little fertilizer, you can grow them in poor soil, too.

The plant withstands droughts, and heat very well. Chances are, you will not have to water them during a drought. Fertilizer is not usually required, except in the poorest of soils.

The plants are aggressive growers, crowding out other plants if given the chance. Give them plenty of space away from other plants in your garden. Or, better still, put in a border edging, dug 3-4 inches deep.

One of the great things about growing mint is that deer and other foraging animals avoid it. They do not like the strong scent.

Insect and Plant Disease Problems

Insect and disease problems are uncommon. Mint has natural repellents for insects and is sometimes used in organic sprays.

Ants do not like Mints – As a result, they are good companion plants. Grow them around your other crops. Or, use mint oil in a spray.

How to Harvest Mint Herb

The best time to harvest them is just before the flowers appear because at this time the flavor is best and the oils are at their strongest. The oils in mint plants are in the glands of the leaves. Crushing them releases the oils and the pleasant, strong, and soothing flavor. After the plant has a dozen or so leaves, you can begin to harvest them. Take just a few leaves while the plant is small. Never take more than 1/3 of the foliage, or you will retard the development of the plant. Once it is well-established you will always have more than enough leaves to harvest.

Harvest mint leaves at any time. They can be used fresh, dried, or frozen. Like other herbs, pick them in the morning, when the oils are strongest. Spread leaves out to dry in a cool and ventilated area.

Tip: Mint has a very strong, overpowering scent. Once it is dry, store it in an air-tight container. Keep it away from other herbs.
