How to grow calamint

Let’s discuss them one by one, 

Grow in the container

Growing herbs planted in a container or a pot is a good way to deal with them.

In a container when plants are grown, they don’t spread much and need low maintenance.

Calamint or any other herb plant are grown for their leaves, planting in a pot provides you enough leaves.

They grow invasively, if you plant them directly in the garden, after a few months they invade other plants and occupy a large area.

How to Transplant calamint

Herbs get easily transplanted. Growing calamint from seed needs lots of time and effort.

So, buy a small calamint plant from a nearby nursery and transplant it in a container or a pot.

  • Take a large container or a pot, that has a drain hole in the bottom, to flow extra water.
  • Put some small rock in the bottom of the container, to provide a proper water and air circulation system for the plant.
  • Fill some soil in the container. Always use rich compost soil for gardening, they have required nutrients.


  • Water the soil and put plants on it.
  • Then fill soil around the base of the plant so that roots are not visible. 
  • Pour water to moist soil. Always water plants from its base.
  • Watering from the top of the plant or from the foliage might attract bacteria.
  • Calamint doesn’t need much water. Water only when the soil gets dried.

Prune calamint

Calamint grows well so sometimes it’s considered a weed.

Occasionally trimming your plant makes them look neat and clean.

Growing herb plants means producing quality foliage. Calamint self-seed easily.

So, most gardeners deadhead flowers before they release seeds, the plant uses most of its energy in growing flowers instead of leaves.

But having a few flowers in the plant is essential. The flowers start seeding in September.

So, deadhead earlier flowers encourage foliage, and in the second round let some flowers grow.

If flowers are not growing then trim some green, to redirect energy to flowers. These tricks pick your calamint to look constructive and balanced.

Let’s see them.

Growing problems

One of the common complaints about this plant is that it reseeds quickly.

Unless you want to grow these mint mighty.

To control their growth you have to prune the flowers before producing seeds or take measures to prevent rooting such as landscape fabric.

You can also try some of its hybrids such as C. nepeta ‘Montrose White’ that don’t face these problems.

In the hot or humid summer, the foliage often loses its vision in the sun.

To prevent this, place your plant where it gets afternoon shade. Also, avoid overwatering, it makes things more humid.


As I said earlier this plant is pest-resistant but whitefly is consistently reported to bother calamint.

To get rid of these whiteflies

  • Sprinkle water on the plant, usually wash the insects away.
  • Use insecticidal soap for heavier infestations. 
  • Periodically apply natural neem oil to prevent flies from settling on the plant.


Powdery mildew is a fungal growth that looks like white powder.

They spot in the leaves and turn their color to first yellow and then brown. This fungus stunts the growth of the plant and prevents flowers from growing.

Usually this fungal thrives at the end of the growing season, keep eyes on the plant.

This white dusty fungus can quickly spread to the whole plant. To prevent them apply neem oil or heavily diluted vinegar (on occasion).

If fungal is already grown then treat them with potassium bicarbonate, sulfur spray, or copper fungicide.
