Spearmint herbal tea in a box

Spearmint, also known as garden mint, common mint, lamb mint, and mackerel mint, is a species of mint, Mentha spicata, native to Europe and southern temperate Asia, that many gardeners have cultivated for the aromatic flavor it brings to food and herbal teas. Spearmint is a perennial plant with tiny purple flowers and very fragrant spear-shaped leaves (that is where it gets its name from). As well as kitchen favorite, Mentha spicata is also used to flavor toothpaste, mouthwash, chewing gum, and candy because of its pleasantly sweet taste. A common way of enjoying this herb is to brew into a tea that can be either made from fresh or dried leaves.

This mint, however, is not only delicious but may also be great for you. Mentha spicata has one of the food's highest antioxidant capabilities that help protect and repair free radical damage. It has been used to treat a number of health issues for decades, including gastrointestinal distress, memory issues, and respiratory diseases. It is also good for memory enhancement and stress relief. Occasionally spearmint tea is consumed to ease a sore throat. It also has beneficial effects on the female’s body by decreasing male hormones such as testosterone and increasing hormones, which help ovulation. Because of the testosterone decrease studies show that two cups of organic spearmint tea a day can help reduce the growth of women's facial hair. Herb contains an acid anti-inflammatory agent that has been studied for its effectiveness in relieving symptoms of seasonal allergy. Garden mint has antibacterial activity against several harmful types of bacteria, including bacteria that cause foodborne diseases, such as E. coli and Listeria. Spearmint has shown beneficial effects in both human and animal research on arthritis pain. In addition, tea made from this herb can help to reduce arthritis-induced stiffness and disability.

Preparation for planning spearmint seeds

Before you start, find a place in your garden where the plant will receive morning sun and partial afternoon shade. Choose a regular light soil with a neutral pH of 6.0-7.0 and good drainage. They prefer ideally a moist but well-drained site along stream banks but the good news is that this plant can readily adapt to grow in various types of soil.

Study your room carefully before planting and decide whether to grow garden mint in a container or in a separate garden area. One piece of advice here, spearmint spreads through a robust root system in the garden a lot, so it may be best to confine it to the balcony planters. Advanced gardeners who have dedicated garden space may consider directly planting organic spearmint on the ground.

How to grow spearmint seeds

Sow indoors 8 to 10 weeks prior to the last frost, or in April to May direct sow. Put them on top of well-worked soil to sow the seeds outdoors, then sprinkle on top of them a fine layer of wood chips. If you are sowing in the garden directly, consider placing a row cover over the seeds until it sprouts.

Seeds are expected to sprout in 10-16 days. Higher temperatures can accelerate germination so find a warm place in your house. Many gardeners plant spearmint in spring, but common mint can also be planted in autumn, particularly in Southern California, where it thrives in the colder, moister winter.

Growing spearmint seeds in pots

It is easy to grow and plant organic spearmint in a port. Look for a pot that has a diameter of at least 30 cm (12 inches) with drainage holes in the bottom. Seedlings and transplants need the same depth to be planted in the container as they grew in their previous one. Seeds are sow 0.5 cm (1/4 inch) deep and place in each container two to three seeds to ensure germination. Hold the soil moist and hold temperatures close to 21 °C (70 °F) until the seeds of the spearmint germinate, normally 7 to 10 days.

A place that receives 6 or more hours of daily sunshine provides enough light for lush development, while outdoor containers can tolerate some light afternoon shade. Also, you can always bring the pot indoors during the cold season to sit on a sunny windowsill. If indoors rotate the plant every 3 to 4 days. Spearmint plants grow in the direction of sunlight, and it helps to keep the plant from growing unevenly by rotating.

Mentha spicata can move its roots through drainage holes and into garden soil if planted in a container that sits directly on the ground. Remember to place a tank under your Mentha spicata for true containment that is not directly on or touching any garden soil. Their roots are shallow and easy to pull out, so as long as you provide physical barriers such as walls, walkways, or containers, there is no reason to worry.

How to stop spearmint spreading in your garden

Raising barriers is the key to stop your garden mint from spreading. Container rims and regular pruning control spreading spearmint stems. This herb spreads above ground by growing roots from stems that touch the soil. As we said before, container rims protruding 2 to 3 cm (1 inch) 1 inch above the soil guide spearmint stems upward and helps prevent them from rooting.

Caring for spearmint

Spearmint does not need a great deal of care, it is undemanding. Your primary job will be to keep up with its rapid growth. Remember to keep the soil moist and ensure that any weeds are removed. We suggest providing some shade for warm-season plantings to decrease heat stress. Use light mulch for outdoor plants. This helps to keep the soil moist and clean the leaves. Make sure to water them frequently for indoor plants to keep the soil evenly moist.

Every few months, top-dress your plants with a thin layer of compost or organic fertilizer for the best growth in confined areas such as containers. In cold climates, bottom pots will need winter protection.

Pinch your organic spearmint to keep it bushy. Try not to let if flower and if you do see flowers, cut them off right away as this will speed up the growth.

How to harvest spearmint

The key to keeping organic spearmint plants at their best is daily harvesting. Spearmint enjoys picking and pruning. Young leaves have more flavor than older leaves, and garden mint can be picked as soon as spring comes up. Cut the stems 2 to 3 cm (1 inch) from the ground immediately before flowering. In a growing season, you can harvest one spearmint plant two or three times. You can also pick the leaves as you need them.

The flowers are edible so they can also be harvested and used in your favorite salads and sweets.

How to store spearmint

While fresh is best and sprigs can be kept in water for a few days, spearmint leaves may be frozen or bunches may be airdried. If you want to dry them, cut the leaves just before they bloom. Place the dried leaves in an airtight container or even better in a jar and it will last for years.

Spearmint companion plants

Mentha spicata attracts earthworms, hoverflies, and predatory wasps and repels moths from cabbage, aphids, and beetles from fleas. Carrots are another plant companion and also spearmint discourages carrot root fly. Spearmint's pungent scent confuses the insect which seeks its smelling meal. It is the same with onion flies. The flies will be baffled by planting garden mint next to onions. As the organic spearmint scent deters aphids and other pests, tomatoes also benefit from planting Mentha spicata close to them. Talking of aphids, you will also repel these insects by planting spearmint near your prize roses. Other plan companions to common mint include beets, lettuce, peas, squash, eggplant, chili or bell peppers, legumes, and Brussels sprouts.

Spearmint is invasive, so cut your herb regularly when it is next to Brassicas or restrain it in containers around your vegetable garden. Do not plant near your parsley, strawberries, and chamomile. Though looking good avoid planting spearmint in a single container with lavender, rosemary, sage, and thyme, as these herbs prefer dry-down soil and sunny spots.
