Planting, Growing, and Harvesting Mint

Mint is a perennial with very fragrant, toothed leaves and tiny purple, pink, or white flowers. It has a fruity, aromatic taste.
There are many varieties of mint—all fragrant, whether shiny or fuzzy, smooth or crinkled, bright green or variegated. However, you can always tell a member of the mint family by its square stem. Rolling it between your fingers, you’ll notice a pungent scent and think of candy, sweet teas, or maybe even mint juleps.
As well as kitchen companions, mints are used as garden accents, ground covers, air fresheners, and herbal medicines. They’re as beautiful as they are functional, and they’re foolproof to grow, thriving in sun and shade all over North America. In fact, mint can be vigorous spreaders, so be careful where you plant it.

Planting

• Mints are vigorous perennials that thrive in light soil with good drainage.
• Ideally, they prefer a moist but well-drained site, something like their native habitat along stream banks.
• Most will tolerate some shade, and the variegated types may require some protection from direct sun.
• For growing outdoors, plant one or two purchased plants (or one or two cuttings from a friend) about 2 feet apart in moist soil. One or two plants will easily cover the ground. Mint should grow to be 1 or 2 feet tall.
• For the best growth in confined areas such as containers, topdress plants with a thin layer of compost or organic fertilizer every few months. Aboveground pots will need winter protection in cold climates.
• In the garden, plant mint near cabbage and tomatoes.

Care

• Minimal care is needed for mint. For outdoor plants, use a light mulch. This will help keep the soil moist and keep the leaves clean.
• For indoor plants, be sure to water them regularly to keep the soil evenly moist.
• At first, mints develop into well-behaved–looking, bushy, upright clumps, but they soon set out to conquer new territory with horizontal runners and underground rhizomes. Unless you block the advance, a pert peppermint plant can turn into a sprawling 4-foot giant in just 1 year. It’s not the stuff of horror movies, however. Mints benefit from picking and pruning. They are shallow-rooted and easy to pull out, so there’s no reason to worry, as long as you provide physical barriers such as walls, walkways, or containers.

Pests/Diseases

• Powdery mildew
• Rust
• Leaf spot
• Anthracnose
• Stem canker
• Mice dislike the smell of peppermint. Spread it liberally where you suspect the critters. Mint is also considered a deer-resistant plant.

Harvest/Storage

• Frequent harvesting is the key to keeping mint plants at their best. Young leaves have more flavor than old ones, and mint can be harvested as soon as it comes up in spring. Although fresh is best and sprigs keep for a few days in water, mint leaves can be frozen or air-dried in bunches.
• Right before flowering, cut the stems 1 inch from the ground. You can harvest one mint plant two or three times in one growing season.
• You can also just pick the leaves as you need them.
• You can grow the plants indoors for fresh leaves throughout the winter. If you want to dry them, it’s best to cut the leaves right before flowering. Store the dried leaves in an airtight container.

Propagating Mint

The best way to propagate mints is by taking cuttings from those that you like best. It’s easy—take 6-inch cuttings of rooted stems and plant them horizontally in the soil. Mint stems will also root in a glass of water. Start with a small cutting from an established plant. Any gardening friend will give you a cutting of a favorite mint.

Cooking Notes

Serious cooks generally prefer spearmint for savory dishes and peppermint for desserts. For a delicate mint taste in fruit salads, yogurt, or tea, try apple or orange mint. Mint lurks in the background in Middle Eastern salads, such as tabouli, and does well with lamb. It also goes with peas, zucchini, fresh beans, marinades for summer vegetables, cold soups, fruit salads, and cheese.
