To prevent it from drying out, it should be exposed to a moderate amount of light.

It is advisable to plant mint in an area where it receives sunlight during the day and a little shade in the afternoon.

Ideally, they receivebetween 4 and 6 hours of light a day and the rest in shade.

The ideal temperature is between a constant 15 and 30 ºC.


  • Locate your plants next to a tree to ensure they receive a moderate amount of light.
  • Being an easy-to-grow plant, you can plant it in pots. This will allow you to control the temperature and the amount of light it receives.

How do we water peppermint? Humidity

Peppermint requires a lot of moisture. In fact, the more you water it, the more it grows.

Optimum relative humidity is 70 to 80.


  • Preferably make drip irrigation to regulate the flow of water. This also keeps the foliage dry and prevents the appearance of fungi.
  • The frequency of watering will depend on the particular conditions, however, you must always keep the soil moist, avoiding waterlogging.
  • In soils with good drainage, it supports daily watering very well.

How do we prepare the soil? Substrate and nutrients

Although they adapt relatively well to most soils, they do not tolerate very limestone ones, nor those that are deficient in terms of nutrients.

They do not usually grow in very dry substrates or with many stones, as they prevent the root development of the plant.

The ideal soil should be loose, very moist and fresh, well drained and with sufficient organic matter.

The optimal pH ranges between 5.8 and 7.0

In terms of nutrients, mint is quite demanding, so it is convenient to work the substrate well and add a good amount of nutrients.

The best natural fertilizers arehumus and old manure.

Another recommendation is to plant peppermint in a fairly spacious place, since peppermint grows very easily and expands in the same way.

  • Dark compost is recommended to keep the soil moist and warm.

  2. Moisten the soil before planting mint.This will facilitate the root development of the cuttings. Also, if you plant from seed, the moisture in the soil will prevent the seed from moving easily.
  3. Fertilize the soil.Spread some humus on the soil to improve the overall quality before you start planting the cuttings.
  4. The ideal is to sow peppermint from cuttings of another plant, since it is very difficult to grow it from seed.In certain varieties, it even becomes practically impossible. Cut a branch of about 1 cm and place it in a glass of water.
  5. After a week, roots will begin to emerge. Wait another week to allow the roots to reach an acceptable length. You can add water to the glass as you consider necessary.
  6. Introduce the cutting 5 cm deep, ensuring that the soil is flush.If you are growing peppermint from seeds, bury them no more than 3 centimeters deep. Cover them lightly.
  7. If you plant in soil, remember to keep a separation distance of between 15 and 30 centimeters between each plant.
  8. Water often.This is important, especially during the first year. Make sure that the soil is always moist, but not waterlogged.
  9. Fertilize regularly. Although peppermint grows easily, you can add compost once a month to ensure it has the required nutrients.
  10. Prune your plants.It is recommended to cut the upper part of the plant to prevent it from growing vertically and stimulate more foliage, which translates into a better harvest.
  11. You’ll also need to cut back the flower buds to keep the plant compact, otherwise your plants can spread out of control. This will prolong the harvest season.
  12. Divide the bushes.Because peppermint grows extremely easily, it is recommended that you divide it into several plants from time to time. It is best to do it during the month of April. To do this, carefully pick up the plant from the roots and divide it into two or three plants.
  13. Plant each one immediately 5 cm deep and making sure to water abundantly. You can do this every 3 or 4 years. This helps keep the mint smelling and tasting nice.
  14. Check your plants regularly to avoid pests and diseases. If you like, you can apply a fungicidal spray to counteract mildew.
