What You Must Know about Mint
Mint or Mentha is actually a genus of plants from the family of Lamiaceae. Therefore, you will find numerous mint species to grow.
Different mint species have different usage. In addition, they also have slightly different characteristics. As a result, before you start the process of how to grow mint, you must know more about this plant.
1. Origin and Myth
Mint is originally from temperate regions in Asia and Europe. However, some species of this plant is indigenous to Africa, America, and Australia.
This herb had been used for centuries by ancient civilizations. Mostly, it was used as medicine. But, it was also used as cosmetics and for cooking.
The name of this herb was derived from the name of Naiad-nymph in Greek mythology, Minthe. She is the daughter of Cocytus, the god of the river.
One day, Persephone was jealous of this nymph. Then, she transformed Minthe into a plant, i.e. mint. The word mint itself means ‘green.’
But that is just a Greek myth that we should not believe.
2. Mint Plant Description
Mint is a perennial plant. It is considered as a small plant because its height is between 10 cm and 120 cm. However, it can be quite invasive.
This plant spreads so quickly that it will affect your other plants. In consequence, when you are performing the steps of how to grow mint, you need to find ways to control it.
If you don’t do it, be prepared to have a 130 cm long mint plant in a year.
This plant has small wrinkled leaves in which color range from dark green to pale yellow. They have a strong aroma.
The compounds that produce this aroma are menthol and pulegone. These compounds don’t only give a pleasant aroma to the leaves. They also produce a cooling effect.
The stem of this plant is square. It will grow upward until its maximum height. After that, it will flop and spread its runners.
Mint flowers are pink or white and bloom in the summer. Butterflies and bees will come to your garden when the plant is flowering.
The male flowers bloom before the female flowers. Moreover, the male ones are bigger than the female flowers.
Cross Pollination may occur between two different species of mint with the help of pollinators.
If you want to grow different mint species, you must plant them in different spots and be sure they are far from each other.
Once the flowers are pollinated, you will likely see the mint fruits start to grow. They are called Nutley. Inside them, you will find up to four seeds.
You can germinate them if you want. However, growing mint from seeds is risky because the new plant may not have similar quality with the parent.

How to Grow Mint
There are two ways of how to grow mint. You can grow it from seeds or from cuttings. If you want to propagate it from seeds, the best time for indoor germination is in late winter.
But, if you want to sow them directly to the ground, the best time to do it is in the spring. Before you do it, make sure that the soil is warm enough and the danger of last spring frost has gone.
If you want to grow it from stem cuttings, the best time to plant mint is in the spring if you live in areas with a cooler climate.
But, if you live in a warmer climate, you can plant it in the fall. In order to get these cuttings, you can ask for runners from your friends who grow it.
You can also buy a small potted mint plant from the nursery. When it is old enough, you can propagate it.
These are the steps of how to grow mint.
1. Germinating The seeds and Preparing The Cuttings
To germinate mint seeds, you need a seed pot and seed starting mix. Sow the seeds in this pot. But, don’t sow it too deeply. It is recommended to sow it in 7 mm deep.
Then, keep the seed starting mix moist and place the pot in a protected place.
Moreover, you also need to keep the temperature around 21o C. It will take about 1 to 2 weeks for the seeds to germinate.
After the seedlings emerge, place the pot in a sunny window. You can also use fluorescent light. If you are using it, turn the light off at night for 8 hours.
When the spring comes, you can transplant them to the ground or to bigger pots. Before that, you need to remember to harden the seedlings for a couple of days.
To propagate mint from stem cuttings, you must cut its stem below a node. After that, remove all the leaves, except the top ones. Next, you need to put it inside a jar filled with an inch of water.
You need to change the water every day. Moreover, you must not expose the jar to direct sunlight so that the cuttings will develop the root successfully. It usually takes a week for the stem to grow roots.
When the seedlings or cuttings are big enough to be transplanted or when the temperature is warm enough, you can start the next step of how to grow mint, i.e. transplanting.
But, before you do it, you need to prepare the planting site or the pots.
If you want to grow mint directly to the ground, you need to loosen the soil, about 20 cm deep. Mix the loose soil with compost if your soil is not rich in organic matter.
Plant the seedlings with 45 cm space between them. Once you plant it, you must water it.
If you grow this herb in a pot, use high quality potting mix to fill in the pots. After that, you can transplant your seedlings or cuttings.
Then, water the plant and place the pot in a shady area at first.
3. Taking Care of The Plant
This plant is pretty caring easy. You only need to fertilize it every two or three months. However, you need to make sure that the plant gets enough water and the soil to stay moist.
To maintain the moisture, you can add a thin layer of mulch on the soil around the mint plant.
It is important for you to prune the plant regularly. This will help you to control the invasive nature of this herb.
Therefore, it won’t steal the nutrition of other plants. In winter, you can bring potted mint plants indoors to protect them from the cold.
You can harvest your mint leaves when the plant is about 8 cm tall. This herb requires regular harvesting to encourage growth.
When you see the plant start flowering, you must cut its stem and leave only an inch of stem above the ground.
From the steps of how to grow mint above, it can be concluded that growing this herb is very easy. Therefore, you will not find big problems in doing it.
However, you need to make sure that you have enough time to prune and control the growth of this plant.
