Mimosa pudica: cultivation in pots

The mimosa pudica plants can also be grown in pots using a mixture composed in equal parts of universal soil, peat and a part of sand. Exposure at home or outside must be bright but not in direct sunlight to avoid sunburn on the leaves. If grown as a houseplant, it should be exposed for at least 6 hours a day to light filtered by a clear curtain. It should be watered with water at room temperature (cold water causes the leaves to yellow) when the first 2.5 cm of soil are completely dry and a good way to check this is to insert a finger into the substrate.


The sensitive Mimosa should be repotted when the root system has occupied all the space at its disposal in the container, usually every year at the end of winter. The new pot must be larger and deeper than the previous one and the fresh soil mixed with some organic fertilizer, home compost or ground lupins. When the plant reaches dimensions that are difficult to contain, it is a sign that it is time to plant it in the ground.


Multiplication of mimosa pudica

The Mimosa pudica propagates by seed and by semi-woody cuttings.


Sowing should be done in spring using universal soil mixed with peat and sand, always kept humid until germination takes place, which will take three or four weeks.

When the young seedlings born in the seedbed are 5 cm high, they must be repotted in small single pots, initially 8-10 cm in diameter and placed in a bright place but sheltered from direct sunlight, also having the foresight to keep the soil constantly moist. .

Multiplication by cuttings

In summer, take semi-woody cuttings of branches of the year and root them in peat and sand soil until rooting and then plant them in the ground or in individual pots to enjoy their flowering from the first year. Rooting of the cuttings will take 40 days.


Pruning of mimosa pudica

After flowering, dry and damaged branches must be eliminated, those that are too long should be shortened to give harmony of shape to the foliage. The cuts must be oblique to prevent water from causing fungal infections and the shears used for pruning must be disinfected with a flame or with bleach.

Diseases and parasites of mimosa

Mimosa pudica fears root rot caused by water stagnation, some fungal diseases when the climate is particularly humid.

Between parasites animals fear attack:

  • aphids and scale insects that colonize the branches, leaves and even the flowers;
  • of the red spider, a small mite that weaves very thick cobwebs especially among the innermost branches.


Cures and treatments

In areas with very harsh winters it is advisable to protect the root system of Mimosa pudica with a light mulch of dry leaves or straw and then remove it in the following spring or when the risk of frost is definitively averted.

Pesticide treatments should be applied at the first signs of infestation by spraying the foliage with specific products, preferably organic. Infestations of aphids can in fact be fought with the garlic pesticide, the macerate of nettle or nebulizations of water and potassium soap.
