When the temperature is very low in winter, mint needs to be moved to a warm place for maintenance. Mint can withstand temperatures as low as minus 15 degrees Celsius and is a very cold-tolerant plant, but you should also pay attention to anti-freezing and try to keep it at around 5 to 10 degrees Celsius. At the same time, you can also cover it with an extra layer of soil in winter, which can also have a thermal insulation effect. If you do these things well, your mint will survive the winter successfully.

Soil and flower pots

If you want to grow mint in autumn and winter, in order to prevent it from being disturbed by low temperatures and causing large areas of yellow leaves and dead branches, you need to always keep it in the form of pots. This makes it easy to move it in and out at any time and move it to a suitable location, ensuring that the plants are always in a growing state.

In addition, poor soil quality can still meet the basic needs of mint for survival. But if you want the stems and leaves to grow faster, it’s more worry-free. You need to directly use loose, breathable and fertile nutrient soil, so that if you don't usually topdress, it will not affect the reproduction of the next generation of the plant and the growth of more side branches on the main trunk.

Appropriate light

Mint only likes weak diffuse light. When the temperature gradually drops, the light intensity will continue to weaken. During this gradual change, we need to always give the plants full-day sunlight.

However, if the temperature of the natural environment continues to be lower than 8 degrees, then the mint potted plants must be moved indoors in time to keep warm and keep out the cold.

Conservation temperature

During this period, it is still necessary to provide sufficient light, and place the potted plants in a place with sufficient diffuse light and easy ventilation.

When the weather is generally sunny and the natural temperature outside does not fall below 0 degrees, we can take advantage of the good weather during the day and open the windows. This can promote indoor and outdoor air convection, create a better home environment, and protect the healthy growth of mint.

If the outside temperature continues to be low, you can keep the windows closed. The premise is not to place too many potted mint plants indoors to prevent them from competing with each other for oxygen or carbon dioxide.

Water appropriately

Mint likes moist soil conditions. Therefore, if the potting soil is sufficiently breathable, even in autumn and winter, the interval between watering should not exceed 5 days when placed indoors.

Of course, if the indoor temperature is too low, it cannot remain stable above 15 degrees. When we water, don't wet all the soil at once, just use the shower head to slightly moisten the soil.

When the soil is wet or dry, the soil needs to be turned. Let air enter the soil, or allow water to escape from the soil in time.

Prune in time

Mint needs to be picked from time to time, if its stems and leaves are often used for cooking. Then, there is no need to deliberately prune off some branches and leaves to stimulate the development of new stems and leaves. And if we don’t usually pick, we’d better learn to top out regularly and prune the branches and leaves at least once a month.

In addition, autumn is a critical period for mint to set seeds. At this stage, we can stop pruning and let it die slowly. During this period, you can prune off some of the naturally aging branches and throw them into loose, fertile soil. Maintain in the open air, so that the seeds will emerge at any time, and when the temperature is suitable, they will grow wildly and spread.
