Mimosa - care and wintering: very

Generally, the mimosa is kept in our latitudes as a houseplant, you can put them in the summer but also in the garden. The mimosa, also known as a stir-me-not-an, belongs to the family of legume / butterfly plants (Fabaceae, Leguminosae) and the subfamily of mimosa plants (Mimosoideae).

The right location for mimosa

The mimosa comes from tropical South America, where it grows in the woods. In this country, however, the mimosa is cultivated as an ornamental plant. Above all, as a houseplant.
As a location, the mimosa appreciates a bright and very quiet location. Direct sunshine like the Mimosenicht and especially young plants should be absolutely protected from direct sunlight. At temperatures, the plant is relatively undemanding, but it does not like any frost. Normal room temperature or outdoors summer temperatures without direct sunlight are perfect for the plants.
It is important that you do not expose the plants to drafts and they do not experience constant vibrations, because in this case, the leaves and small branches regularly pull together. This is very stressful for the plant and weakens it permanently.

Earth and fertilization

The soil for the plant should be loose and compost-based. After the purchase you should repot the plant immediately and check regularly, because mimosa grow relatively quickly. If the roots are sticking out of the pot, it's time to repot. The soil should always be slightly moist, but the plant does not tolerate too much water. So it has to be poured moderately but regularly. If she gets too much water on a regular basis, she absorbs it all the same, but ultimately she does.
For the plant to grow well, it needs regular fertilization. The plant survives without fertilization. For the fertilization one should use green plant fertilizers from the trade, give this however only in the half recommended concentration. Young plants should not be fertilized yet.

Mimosa: Origin of the name

Mimosa is a very interesting plant because it responds to touch or vibration. If you touch the plant, it will fold in its leaves. And that in a fraction of a second. The re-erection of the leaves can take up to half an hour. This folding of the leaves can also be observed at night, so to speak as a sleeping position. At night the plant does not react so noticeably to touch.


The mimosa has long thin shoots, which are provided with protective thorns. It has only a few leaves, and only about 50-70 cm high. The flowers of mimosa do not last long. Each flower only lives for one day. However, it quickly produces new buds that also open in a very short time. So you always have flowers on the plant in the flowering phase. It blooms in a very nice pink color.

Care of mimosa

In the care, the mimosa is not easy. Mimosas want to be relatively wet, but waterlogging is not tolerated. She has the ability to run away. She takes on water over and over again until she eventually falls over. If that happens, it is already too late, the plant is beyond salvation.
  • Preference is given to a bright location, without direct sunlight.
  • It feels most comfortable at room temperature, frost and draft is not tolerated.
  • It is best to position the plant so that it can stand still without having to be touched frequently (overhanging shoots).
  • Each folding of the leaves costs the plant a lot of strength, and should therefore be avoided.
  • The mimosa grows rapidly, so a frequent repot is necessary. If the root comes through in the pot below, that is a sure sign that it should be repotted.
  • Repotting should be done as swiftly as possible to minimize stress on the plant as much as possible.

Cut the plant

If the plant is very bulky, a cut is appropriate. However, one should cut the plant as rarely as possible and completely dispense with the cut in young mimosa. After the cut, however, it is always uncertain whether the plant will go out again as desired. Often this is not the case and the mimosa then looks somewhat plucked after the cut. It is easier to grow a new plant from seeds - which is very simple - and then replace the old and too bulky plant with young mimosa.

The multiplication of mimosa

The mimosa is also very easy to grow from seed to seed:
  • The perfect time for sowing is spring. It makes sense to pre-germinate the seeds.
  • To do this, douse the seeds with hot water and let them soak for several hours, swelling slightly.
  • If necessary, replicate the overflow if the seeds do not swell in the first attempt.
  • After that, the seeds are ready for planting.Sow seeds or Kokohum are used to plant seeds, as both are germ-free.
  • The seeds must be covered with a thin layer of earth. The location for the seed pot should be bright and warm.
  • It is important to keep the substrate evenly moist. For the irrigation is a spray bottle, because you can moisten better dosed with this.

Diseases and pests of mimosa

One pest that attacks mimosa more often is the spider mite, which is recognizable by the fine mesh that surrounds the plant and is best recognized by spraying the plant with water. For first aid, rinse the plant gently with a stream of water. Thereafter, the use of a spray against the pest is necessary because not all animals are eliminated by rinsing and because two surviving pests are sufficient to start a new population on the mimosa.
It makes sense to use a systemic agent that is absorbed by the plant and absorbed by the spider mites when it is sucked out of the plant. Important is a repeated application to destroy the eggs. Especially in the wintering phase, the risk of infestation of spider mites due to the drier indoor air is very high. However, mimosa should be regularly checked for spider mite infestation in any season.

Mimosa overwinter

Mimosa is a plant that likes to hibernate. However, the wintering is not very difficult, as the plant only reaches a height of 30 to 50 centimeters and therefore has no high demands on locations. Up to 10 degrees Celsius outside temperature, the mimosa can easily stay outside.
  • Later this fall, she will be brought indoors and wintered in a room that is bright and offers about 15 degrees Celsius room temperature. The humidity must not be too low, because otherwise the plant will be affected by the spider mite.

  • The care requirements of mimosa are very low in winter. That's why it needs to be watered even less in the winter than in the summer, and fertilizing is completely over during the wintering phase.

  • From about February, the plant is first placed in a room that has normal room temperature. The plant should slowly get used to the sun, because otherwise its leaves burn quickly.

  • Therefore, after hibernation you should put the plant in the shade or partial shade, where it is also protected from the midday sun.
