Guide to Mint Plants

Mint, with its bright, sharp, wake-you-up flavor, is one of the easiest herb plants you can grow.

Mint has multiple uses. Its fresh green leaves add a tangy punch to fruit salads, ice cream, sherbet, and brewed hot tea. It is a low-calorie, flavorful addition to a simple glass of still or sparkling water. And who ever heard of a mint julep without the mint?

Once you plant it, mint (Mentha species), a perennial, becomes a constant garden companion, although some kinds are tougher than others. If you're feeling kind, you can call mint plants aggressive. If you don't like thugs taking over your garden, you will consider mint invasive.

Grow Mint Plants in Containers

Because it grows by underground root runners, mint spreads easily and quickly. To contain it, grow mint in a 12- to 16-inch-wide pot so it can't ramble through your landscape. If you like, tuck the container into the ground so the pot doesn't show but still keeps the herb in check.

You also can plant mint in a large half-barrel or plastic pot and leave it outdoors year-round. Don't keep ceramic pots outdoors during winter; they often crack during the freeze-thaw cycles that follow freezing temperatures.

How to Grow Mint Plants

Plant mint in full sun or part shade. It thrives in rich, moist, well-drained soil. Mint adapts to many soil types, but develops the best foliage in soil that has been enriched with a 2-inch-thick layer of compost.

Frequent cutting keeps mint looking attractive. As with basil and other flowering herbs grown for their leaves, remove flowers as they appear, and pinch back the stems to encourage shorter, bushier growth. Keep the area around mint free of weeds and grass. Otherwise it looks untidy, and the weeds may reduce yields and affect flavor.

Divide mint every few years. In fall, cut the plants to the ground.

Pests and Diseases of Mint

Mint plants can fall prey to a number of pest problems, including diseases such as verticillium wilt, mint rust, mint anthracnose, and insects such as spider mites, flea beetles, root borers, cutworms, and root weevils. Aphids are occasionally troublesome. Provide good air circulation and well-drained soil to prevent foliar diseases; knock off insects using a spray from a garden hose, being sure to spray the undersides of leaves where pests can hide.

How to Harvest Mint

Cut the leaves and flower tops when the mint plants start to bloom. Use fresh leaves immediately, or freeze them to retain their bright color.

To air-dry mint, hang the stems upside down in small bundles or spread them loosely in a small tray. When the stems and leaves are brittle, remove the leaves and flowers and store them in airtight containers.

What About Catmint?

Catmint (Nepeta) is a different plant, though related. It grows in much the same way as the herbal mints described here, but its flavor is much more attractive to your cat than it will be for you. Catmint can be dried or used fresh. Many types of catmint species are grown in the garden for their attractive blue-purple, white, or pink flowers.
