Pineapple mint plants (Mentha suaveolens ‘Variegata’) are among the most attractive varieties of mints. There are a number of pineapple mint uses that make this versatile plant well worth growing. Use it in beverages, as an attractive garnish, in potpourris and in any dish that calls for mint. It makes an attractive and fragrant ground cover, and also grows well in containers and hanging baskets. The only problem with pineapple mint is that it spreads vigorously. This can be good if you want to use it as a ground cover to fill an area, but it will eventually find its way into the rest of the garden unless you install a deep edging around it. Growing pineapple mint in containers is a good way to keep this and other mints under control, but you’ll still need to take some precautions. The plant has been known to escape through the drainage holes in the bottoms of pots and even jump from pot to pot in container groupings.[图片]What is Pineapple Mint? Pineapple mint is a variegated cultivar of apple mint (Mentha suaveolens). It features attractive, variegated leaves, usually with white margins, on plants that grow up to a foot tall. The leaves are bumpy and hairy and the white edging can make them look as though they are sporting a ruffle. White or light pink flowers bloom on small spikes at the top of the plant in summer. The flowers attract a wide variety of pollinating insects, including bees and butterflies. Deer dislike strong fragrances and hairy leaves, so they have two reasons to dislike pineapple mint.[图片]How to Care for Pineapple Mint Grow pineapple mint in full sun or partial shade in rich, moist soil. Plants grown in sun tend to stand upright, while those that get afternoon shade sprawl near the ground. Keep the soil evenly moist until the plants are well-established. Once they are growing well, you’ll only need to water them during dry spells. The plants don’t need regular fertilization when planted in good garden soil. Older plants become woody and unattractive. Pull them up and let younger plants fill in the empty space.[图片]Pinch out the growing tips of pineapple mint plants regularly to keep them compact and bushy. You may occasionally find solid green sprigs of mint mixed in with your pineapple mint. These are sprigs of apple mint — the parent plant of the pineapple mint cultivar. You should pinch them out as you find them because, like most variegated plants, pineapple mint isn’t as vigorous as its non-variegated parent plant, and the apple mint will soon take over.

There are over a thousand different varieties of mint. Ginger mint (Mentha x gracilis syn. Mentha x gentilis) is a cross between corn mint and spearmint, and smells very much like spearmint. Often called slender mint or scotch mint, variegated ginger mint plants have beautiful bright yellow stripes on the leaves. Let’s learn more about growing ginger mint plants.[图片]Growing Ginger Mint Ginger mint, like all other varieties of mint, is easy to grow and can quickly get out of hand when allowed to grow freely. If you have the space to let your mint plants run, it will kindly oblige. Otherwise, it’s best to contain it in a pot of some kind. To keep growth under control, you can even cut the bottom out of large coffee can and place this in the ground. This mint is not particularly picky about the soil it grows in as long as it is not too dry. Ginger mint will even grow well in heavy soils loaded with clay. Place plants in a sunny or partly sunny location for best results.[图片]Care of Ginger Mint Herbs If you plant your mint in a container, be sure to keep the soil amply moist. Containers dry out quickly in the hot summer heat. Check the soil a couple of times a week to be sure that it is moist to touch. Ginger mint in the garden will appreciate a generous layer of mulch. Use garden compost, bark chips, cocoa shells or other finely shredded compost. This will help to retain moisture and protect the ginger mint herbs over the winter. Feed your plants with bone meal twice a year for best performance. To keep your mints plants looking their best, clip the older woody stems back to allow younger shoots to fill in. In late fall, cut the plants back to the ground. This protects the plant and allow vital energy to be put into new growth for the following season. Harvest young shoots as they appear in the spring. Always collect mint leaves on a dry day before the hot sun comes out and use right away for best taste. Division is easily accomplished any time of the year; however, spring or fall is best. Any part of the root will grow a new plant.[图片]Ginger Mint Uses Ginger mint herbs are a delightful addition to fresh summer melon salads, as well as warm or cool teas and lemonade. Finely chopped pieces of mint can be added to softened butter for a delicious spread. Fresh grilled meats taste great with a lemon juice and mint leaf marinade.

Watermint plants are aquatic to riparian flora. It naturally occurs in northern Europe along waterways, in storm ditches and near rivers and other waterways. Older generations had many thoughts on how to use watermint. It has topical uses, can be made into a tea, helps in natural pest control and other properties. Mentha aquatica, as it is known to botanical students, is abundant in its native range and hardy in USDA zones 8 to 11.[图片]What is Watermint? Shore plants, like watermint, are important for erosion control, food sources, animal habitat and simple waterline beauty. What is watermint? Growing watermint around the pond will add fragrance in the summer blooming season and attract butterflies and pollinating insects. The midsummer blooms are caps of tiny florets amassed into a larger flower in deep hues of purple to blue, creating a beautiful effect. Watermint has thick dark green leaves tinged with purple, deeply veined and slightly hairy. Like all mints, this plant spreads with long runners, which root at nodes and create daughter plants. It has the tendency to become invasive, so plant in a container to prevent invasive growth.[图片]Growing Watermint Plant Mentha aquatica along the edges of bodies of water or in shallow water. The plant prefers slightly acidic soil in moist loam. Watermint plants do best in full sun but can also thrive in partial shade. The stems spread out appealingly on top of water and the bright fresh flowers add fragrance and color to the pond or water garden. You can plant the mint directly into the ground but to prevent spreading, try planting in a container with good drainage holes. Sink it directly into the edge of the water so moisture constantly flows around the roots. Watermint has few pest or disease problems, but it tends to get a little rust, so avoid overhead watering in warmer, humid regions. The plant responds favorably to light trimming and will push out thicker growth when cut back. Watermint is a perennial plant that may die back in cold weather but will burst with fresh green growth when temperatures warm.[图片]How to Use Watermint Watermint plants have topical medicinal properties as a balm for sore muscles and an aid for cleaning wounds. The oils in the leaves add flavor to cooking and baking and leaves add a bright zing to salads. You can dry the leaves for use as a tea, which aids in digestion and calms ulcers. As a natural pesticide, it repels flies and mice seem to avoid the scent of the plant. Mentha aquatica distillations are also refreshing additions to mouthwash, body wash and even lotions. The pure refreshing scent can add a boost to potpourri and as an aromatherapy treatment the plant calms and refreshes. As with all mints, the oils and aroma help relieve stuffy noses and clear the breathing passages. Watermint is a valuable and lovely addition to the garden, with uses beyond medicinal and culinary. Add the oil to cleaning products to freshen the home and enliven the air.

What is wild mint or field mint? Field mint (Mentha arvensis) is a wild mint that is native to the central part of the United States. The scent of this wild mint growing in a field is often so strong you can smell it long before you can see it. Keep reading for field mint information and learn about wild mint growing in your garden.[图片]Field Mint Information Native Americans used to drink field mint tea as a remedy for colds, and it’s still used today for teas and flavorings for food. It’s an unusual-looking mint plant, with a square stem that grows from 6 to 18 inches tall with tufts of flowers puffing out around the stem every few inches. As with other types of mint, you can pick mature field mint leaves first thing in the morning for the best flavor. Enjoy them fresh chopped in iced tea, sprinkled on a salad or mixed into a variety of dishes. Dry the leaves for long term storage. You can enjoy mint tea from fresh or dried leaves.[图片]Wild Mint Growing Conditions Planting wild mint begins with choosing the right patch of garden in which to plant it. This plant does not like to get dried out, so sandy soils aren’t the best environment in which to grow your field mint. Dig a good quantity of compost into sandy soils to help keep the soil moist. Make sure your proposed planting site includes full sun, or almost full sun. It can tolerate light shade, but not dappled sun, like underneath a tree. Like any other mint plant, the care of field mint plant isn’t so much a question of keeping it healthy and alive as it is of keeping it held back. Mint is one of the most invasive plants you can put in your garden and can take over an entire yard in a matter of a few years. The easiest and least expensive way to prevent this from happening is by planting all mint plants in containers and never putting them in the garden itself.[图片]Use a rich potting soil and a large pot to allow the mint to spread out a bit, and keep the flowers deadheaded to prevent them from seeding onto nearby soil. Plant field mint seeds in the fall after the leaves have fallen from the trees, or store them in the refrigerator vegetable bin for at least three months before planting them in the spring. Plant the seeds by sprinkling them on top of the soil, then watering them in. Seedlings should sprout in about a week.

Mint growers already know that their plants can grow explosively, making pests out of themselves in places where they’re not welcome, but not all mint growers are aware of an even more obnoxious pest that feeds on these plants. When your well-behaved mint plants suddenly take a bad turn, wilt unexpectedly or seem unwell, mint plant borers may be to blame.[图片]What are Mint Borers? Mint borers are the larval form of a light brown moth that hold their wings over themselves like a partially flattened tent. Adults reach up to 3/4 inch, emerging from mid-June through mid-August. During the week they’re alive, adults lay eggs aggressively on peppermint and spearmint leaves. Larvae emerge in about 10 days and begin feeding on leaves. After a few days, these hungry larvae drop into the soil to chew on root hairs and burrow into the rhizomes of their host plants. The serious mint root borer damage starts at this point and continues for up to three months before the larvae leave the roots to pupate.[图片]How to Treat Mint Borers Mint plant borers are difficult to control because they spend most of their lives hiding inside the roots of plants most gardeners would rather keep alive. Mint root borer damage is subtle, further complicating things; signs like reduced yield, stunted growth and general weakness can be caused by a myriad of plant problems. Beneficial nematodes may be used for mint root borer control, though repeated applications are usually necessary before you see noticeable improvement. Releasing parasitic nematodes at a rate of one to two billion juveniles per acre in late August to early September can help decrease the number of juveniles that make it to adulthood. Space applications a week apart to establish a healthy colony of nematodes and reapply new eggs the following fall to further shore up numbers.[图片]Chemicals like chlorantraniliprole, chlorpyrifos or ethoprop can be applied to beds where mint plant borers are a constant threat, but only chlorantraniliprole should be used during the growing season – you need only wait three days for a safe harvest. Chlorpyrifos requires 90 days between application and harvest, whereas ethoprop needs 225 days.

Pruning mint is a pleasant task, as the plants release a new burst of minty fragrance with each cut you make. You have two objectives when pruning the plant: to keep the bed healthy and to prevent it from flowering and going to seed. Flowering reduces the quality and potency of the leaves. Read on to find out when and how to prune mint plants. Never be afraid to pinch a few sprigs of mint when you need them, but if you need a large quantity of mint, wait until pruning time. If you want a low-growing bed of mint, you can keep it as short as 4 inches. This is a good height for mint grown in small containers. Otherwise, let it grow 8 to 12 inches tall before you prune it.[图片]When to Prune Mint You can sometimes get a light harvest from mint during the first year, but it’s generally best to wait until the second year, just before the plants bloom. After mint blooms, it loses some of its essential oil, making the leaves less fragrant and flavorful. Watch for the buds that indicate when the plant is about to bloom. Once buds appear, you can pinch them or cut back the plants. During the second year, you can cut the plants back two or three times. Trimming mint plants to the ground before winter is an essential part of preventing insect pests and diseases, such as anthracnose, that would otherwise overwinter in the plants.[图片]How to Prune Mint If you’re pruning mint during the growing season, cut the plants back by about half. This will remove the tips of the plant where the flowers would otherwise bloom and provide plenty of mint for fresh use, freezing or drying. When you perform mint plant pruning at the end of the year or end of season, cut them to within an inch of the ground. If you have a large bed, you can use a lawn mower.

Mint is a rapid growing herb that is nearly indestructible. This aromatic plant likes to be cut back and really needs to be or it may take over the garden. On occasion, critters — often worms — decide they like mint as much as you do. What can be done about worms eating a mint plant and what might these worms be? Let’s learn more.[图片]Help, There are Green Worms on Mint Plants! Mint should be grown in partial shade to full sun and is extremely hardy. It can survive temperatures down to -29 degrees F. (-33 C.). Believe me when I say that it can overtake a garden space unless it is controlled. Plant this aromatic herb in soil that is slightly acidic with a pH between 6.0 and 7.0. Even though it’s a tough plant, like all plants, it may become afflicted with some sort of disease or pest. Some of the less desirable nibblers include aphids, thrips, slugs and snails, and of course, even bunnies love to nibble on the sweet-smelling plant. If you witness damage to the plant and rule out the above culprits, another invader might just be worms in the mint plant. Worms in mint plants may be visible as small, green “inch” worms. They look kind of cute but they have a voracious appetite and if you hanker mojitos all summer long, they must be stopped! How can you get rid of these little green worms on the mint plant?[图片]Treatment for Worms Eating Mint Plant Well, you can always visually hunt for them and then squish the worms. It may take a while with this tactic to eradicate the pests, but at least you aren’t poisoning the mint or surrounding area with chemicals. Another organic approach is to use Bacillis thuringiensis. Yes, it’s a mouthful, but all it really is a bacterium that will kill off the caterpillars with little to no effect on you, wildlife, pollinators and other beneficial insects. The down side to this is that you must cut back the mint to the ground prior to applying Bacillis thuringiensis, or Bt. No worries though, as the mint will rapidly regroup. What if you can’t see any worms eating the mint plant? The culprit might still be mint plant worms – cutworms to be exact. Cutworms are nocturnal feeders and then post feast, hiding in the soil during the day at the plant’s base or in its debris. If you dig down a little bit, you may find cutworm larvae. They are 1 to 2 inches in length with a wide range of colors and patterns. A telltale sign it’s a cutworm? They curl into a C-shape when disturbed.[图片]Cutworms aren’t picky about their diet and will eat all manner of veggies as well as other plants. They attack my rhodies on a regular basis. So how can you get rid of cutworms? Maintenance of the garden area is of primary importance and the first step. Clean out any plant debris, ridding the worms of a cozy place to hide. Then spread diatomaceous earth around the base of the mint plants. The sharp diatomaceous soil will cut the insects if they try and crawl over it. It will also keep the snails and slugs at bay if they are a problem for you too. You can also go out at night with a flashlight and hand pluck the larvae from the plant. Lastly, of course, if you choose not to go the organic route, there are insecticides that can be applied to kill the larvae, but why would you deny yourself the pleasure of crawling around in the dark with a flashlight and squishing worms?

If you have herbs in your garden, you likely have mint, but what other plants grow well with mint? Read on to find out about companion planting with mint and a list of mint plant companions.[图片]Companion Planting with Mint Companion planting is when different crops are planted near each other to control pests, aid in pollination, and to harbor beneficial insects. The byproducts of companion planting maximize garden space and increases healthy crop yields. Mint is no exception to this practice. The aromatic aroma of mint isn’t as pleasing to many crop pests, so planting crops next to mint can deter these plant nemeses. So what plants grow well with mint?[图片]Plant Companions for Mint Mint helps deter flea beetles, which chew holes in the foliage, of crops like: Kale Radish Cabbage Cauliflower Carrots are another plant companion for mint and as benefit from its proximity, mint discourages carrot root fly. The pungent scent of mint confuses the insect which finds its dinner by smell. The same is true of onion flies. Planting mint next to onions will baffle the flies. Tomatoes also benefit from comingled mint planting in this way, as the aroma of the mint deters aphids and other pests. Speaking of aphids, planting mint near your prize roses will also repel these pests.[图片]The powerful aromatic oils of mint seem to be beneficial to all of the above mint plant companions in repelling harmful insect pests. Other plant companions for mint include: Beets Broccoli Brussels sprouts Chili and bell peppers Eggplant Kohlrabi Lettuce Peas Salad burnet Squash[图片]Do keep in mind that mint is a prolific spreader, some might become invasive. Once you have mint, you will likely always have mint, and lots of it. But if it keeps the aphids and other winged marauders out of the veggie garden, it’s probably a small price to pay. I’m sure you can find a way to use up all that mint in the garden – mint-pistachio pesto, peas and mint with pancetta, or MOJITOS!

Banana mint plants (Mentha arvensis ‘Banana’) are a variety of mint with bright, fuzzy, lime-green foliage and a pronounced, very delightful aroma of banana. Like all mint plants, growing banana mint is easy. Read on for all the banana mint information you need to get started with this fun, and rather quirky plant.[图片]Banana Mint Information Although these plants are grown primarily for their foliage, the small purple flowers, which bloom throughout the summer, are highly attractive to bees, butterflies and other beneficial insects. Mature height of the plant is about 18 inches. Banana mint plants are perennial, and suitable for growing in USDA plant hardiness zones 5 through 11. Growing Banana Mint Banana mint grows in partial shade or full sunlight and nearly any type of well-drained soil. However, keep in mind that although banana mint may not be quite as rowdy as many of its mint cousins, it can still become quite aggressive. If you’re concerned that the plants may be bullies in your garden, plant them in containers to keep growth in check. Planting seeds isn’t recommended for banana mint, and may not produce the results you’re hoping for. However, it’s easy to start mint cuttings or divisions from an existing plant, or by planting young banana mint plants purchased at a nursery or greenhouse. You can even root banana mint cuttings in a glass of water.[图片]Banana Mint Care Banana mint requires little care. The most important thing is to keep the soil moist, but not saturated. Banana mint plants don’t tolerant dry soil. Harvest banana mint regularly to keep the plant full and attractive. If the plant ever begins to look long and leggy in midsummer, feel free to cut it back by about one-third of its height. It will rebound quickly. Cut the plants nearly to the ground in fall. If you live in the cooler ranges of the acceptable climate zones, a layer of mulch will protect the roots during the winter.[图片]Uses for Banana Mint Fresh banana mint leaves add flavor to hot and cold tea, adult beverages, ice cream and baked goods, such as muffins and cookies. The leaves are also easy to dry for use in the off-season.

Corsican mint (Mentha requienii) is a spreading, ground-hugging plant with petite, round leaves that emit a powerful, minty aroma when bruised. Also known as creeping mint, Corsican mint plants, which spread by narrow stems that take root as they grow, are well suited for filling in around stepping stones or pavers, but aren’t sturdy enough for heavy foot traffic. Read on to learn more about Corsican mint in gardens.[图片]Growing Corsican Mint Corsican mint plants tolerate full or partial sunlight. Nearly any type of moist, well-drained soil is suitable. Keep in mind that, like most mint plants, Corsican mint self-seeds readily and can be somewhat aggressive. This plant is suitable for growing in USDA plant hardiness zones 7 through 9. It freezes in colder climates but usually self-seeds in spring.[图片]Using Corsican Mint In addition to its uses as a groundcover in the garden, Corsican mint is valuable culinary plant and great for containers. Snip the leaves to flavor hot and cold drinks, ice cream and baked goods. Growing Corsican Mint Indoors Corsican mint is easily grown indoors. Use a lightweight, well-drained potting mix and be sure the pot has a drainage hole in the bottom. Place the mint where it receives morning sunlight, but where it is protected from intense light and heat. Water the plant regularly to keep the soil moist, but decrease watering during the winter months, allowing the soil to dry slightly.[图片]Caring for Corsican Mint Corsican mint can be somewhat finicky, especially when it comes to irrigation. These plants don’t tolerate drought, which means the soil should be kept consistently moist but not soggy. Fertilize Corsican mint every spring using a balanced, water-soluble fertilizer. This plant is a light feeder, so avoid over-fertilizing. Thin the plant regularly and avoid overcrowding, as mint plants require plenty of air circulation. Protect Corsican mint plants with a light covering of mulch if you live in a climate where winter freezes are possible. The plant is able to tolerate light frosts without protection.
