Growing Mint As a Houseplant

Mint is an easy and hardy perennial herb to cultivate. It grows as a bushy plant in either sun or shade and is adaptable to multiple soil types.

Start seeds indoors during spring (or fall in warmer climates), or purchase young plants from garden centers, herb nurseries or online plant retailers. Check your soil’s pH level and enrich it as necessary using compost or well-rotted manure.

Planting

Mint plants are easy to cultivate from both seed and transplants purchased from a garden center or nursery, or stem cuttings taken directly from your own mint stems. When planting mint seeds, use a seed tray or small pots with soil surface evenly sown before spreading your seeds out evenly across it all before covering with plastic lid or piece of plastic wrap to maintain humidity and warmth for proper germination of mint seeds – ensure these seed trays are placed in an area with ample sunlight so the light rays reach them! Mint seeds require light in order to germinate properly!

If you prefer planting mint from cuttings, simply take 6-inch stems from existing plants and root them horizontally in a container filled with well-draining potting soil or multipurpose garden soil. Be sure that the edge of your pot sits just slightly higher than soil level so as to not overcrowd it with too many plants.

For optimal mint plant health, water it regularly and apply organic liquid fertilizer once or twice each season. However, beware over-fertilization as this may result in excessive foliage growth and decreased flavor intensity.

To maintain healthy, vigorous mint plants that won’t become too tall and leggy, pruning in spring and mid-summer is essential. A light pruning will encourage more compact mint plants that give off less airborne carbon dioxide emissions. Mint plants are deer and rodent resistant, however if mice become an issue around your mint plants try covering the ground around it with pine bark mulch or chopped hay to deter their presence and regulate soil temperature and moisture. Also using organic mulches helps regulate these factors and decrease weed competition for nutrients which make healthier mint plants!

Watering

Mint plants thrive in containers, garden beds and windowsills alike. Once established, they require little in the way of maintenance; however, one key consideration should be paid attention to: watering. Mint requires consistently moist but not waterlogged soil for healthy growth – too much can cause root rot and stunted development; so it is vitally important that soil moisture levels are monitored closely so as to adjust watering routine accordingly.

The amount of water a mint plant needs depends on a number of variables, including temperature, season and light conditions. As a general guideline, check the top inch of soil for moisture before reaching for your watering can. Watering frequency also varies based on size of pot used to grow mint plants and ambient humidity; smaller potted mint plants often need water more frequently due to quicker evaporation rates than those growing in larger containers.

As mint plants use up nutrients quickly, replenishing them with an application of organic fertilizer or compost is often necessary. This is particularly important in warm, bright environments during their growing season.

Mint is an easy-care herb, capable of withstanding frost and drought while being susceptible to some common pests like slugs, snails, thrips and cutworms. Mulch may help reduce these problems; alternatively weeding, repotting and pruning should all be performed as part of its care routine; pruning is particularly useful in controlling spread by removing large portions of stem and encouraging branching out; additionally it prevents the appearance of fungal diseases like mint rust.

Fertilizing

Mint plants (Mentha spp) thrive in both containers and garden beds, although their prolific spreading can pose some difficulty. To keep it under control, fertilize it regularly while controlling its spread with barriers or fences.

Containers provide the ideal environment for growing mint, as it allows the plant to remain contained with its well-draining pot and soil combination. Choose a 12-inch pot filled with low-fertilizer soil formulated for edible plants; place it in an area receiving four to six hours of daily sun. Indoor mint plants often struggle in dry environments; increase humidity by misting between waterings or placing a tray of pebbles underneath your pot.

When cultivating mint in the ground, all that’s required for success is regular watering and sufficient sunlight. For optimal results, plant in loose, fertile garden soil that has a pH between 6.0-7.0 for best results.

Mint grows best in soil that provides essential nutrients, but these may not always be available to it directly. To combat this issue, mint plants should receive an all-purpose fertilizer every four to six weeks throughout its growing season – beginning early spring. Liquid fertilizers offer quick and easy solutions; just apply a diluted solution directly onto soil around mint plants or use spray-on foliar sprays as extra nutrition boost. Slow-release granular fertilizers are another good choice: sprinkle them evenly around mint plants then water thoroughly to activate them.

Gardeners must remember that mint plants can be susceptible to cross-pollination and hybrid seeds, requiring specific varieties to be planted in separate garden beds or containers to avoid this outcome. Mulching can help keep soil moist and decrease evaporation rates as well as keep weeds at bay.

Pruning

Mint plants tend to flourish quickly and outshout other herbs in gardens or pots quickly, crowding out other flowers quickly and necessitating regular pruning for bushy growth and to prevent legginess. If pruned correctly, mint provides fragrance, flavor and utility throughout many seasons.

Pruning is essential to most plants, but especially essential when growing mint. Pruning encourages branching and denser foliage which makes the plant more visually appealing than a tall, leggy stalk. Pinch back the tops of stems regularly to promote new growth and prevent the plant from becoming leggy.

Pruning should take place either late winter or early spring before your plant has begun growing, to allow maximum utilization of food into developing leaf and stem tissues without creating damage due to overpruning.

As the season advances, pruning should be carried out every four to six weeks to prevent flowering which depletes energy reserves and diminishes flavor and aroma. Removing flowers regularly keeps plants from going to seed and allows a second flowering period in autumn. Use sharp pruners and disinfect tools prior to pruning so as to minimize disease transmission.

As with many gardening tasks, understanding what and why you are doing something will make the task simpler. Steve believes that like raising children, without guidance young plants may do whatever they please during their formative years – which might not always be what is desired!

Harvesting

Mint plants can be aggressive growers, but you can control their vigor by harvesting mint leaves at regular intervals. When indoors for the winter season, harvest the fresh leaves regularly so you always have fresh mint. Or dry the leaves for use in cooking or tea making – however before flowering occurs for best taste and flavor! Alternatively, cuttings of mint plants are easily propagated into houseplants including peppermint (Mentha x piperita), spearmint (Mentha spicata), pineapple mint (Mentha suaveolens ‘Variegata’) and chocolate mint (Mentha x piperita ‘Chocolate Mint’).

Because mint is such an aggressive grower, it requires plenty of water to keep its soil moist. This will allow it to retain its flavor and prevent rot; containers in need to be watered more regularly during periods of extreme summer heat or drought than their ground-grown counterparts. For best results, water mint in either early morning or late evening when temperatures are less likely to cause leaf damage.

To keep mint looking its best, feed it regularly with liquid garden food. Mint thrives in soil that’s rich with organic material and well-drained; in planting beds mix in 3 inches of aged compost or Miracle-Gro(r) Garden Soil All Purpose to improve drainage and nutrient availability; mix equal parts garden soil and potting mix when planting potted containers or mixing equal parts garden soil and potting mix when using pots as potted plants; start feeding mint approximately one month post planting using Miracle-Gro(r) Liquid All Purpose Plant Food; follow label instructions to know when and how much to apply.
