Mimosa - Acacia dealbata

The mimosa is native to the Australian continent. In Italy they resist well in the temperate climates of the central south, but they can also be cultivated on the coasts of the great northern lakes, where they can benefit from milder temperatures. Cultivation in other areas must be done in pots or greenhouses.

There mimosa plant it can also reach considerable sizes. The leaves are composed of many leaflets placed perpendicular to the main rib. Some varieties do not have the classic leaves, but have transformed leaves, which are like flattened twigs, called phyllites.

The inflorescence is composed of a group of globose flower heads from which numerous stamens branch off. The large quantity of flowers gives this plant a very special charm.

the mimosa flowers turn brown when they wither naturally, or when they are in poor cultivation conditions, such as severe drought or excessive humidity.

Plants generally do not experience severe stress when moved from a small pot to the open ground, but it is likely that your plant has undergone transplantation as a dramatic event, and therefore its flowers have simply wilted quickly, as the plant was subjected to a shock.

If it is a problem of this type, I believe that you should not worry, as the plant has only implemented a defense action against adversity: the stress did not allow it to develop at its best, and therefore it gave up. to bring forward the expendable part, that is the flowers. If otherwise the plant is fine, don't worry, next year you will enjoy a longer and more persistent flowering.

If, on the other hand, the plant is kept in conditions that are not conducive to its development, in addition to the withered flowers, you will also notice other symptoms, such as poor spring vegetation, drying leaves or darkened branch tips.

In these cases it is certainly problems in the position of the plant, or in watering.

Mimosas (acacia dealbata) are native to Australia, and were introduced into cultivation in Europe several centuries ago nowadays you can find several examples in Italian gardens, and also in the wild, especially along the coasts and in Puglia, Calabria and Sicily, where you can see small groves, with spectacular blooms towards the end of winter.

These are large shrubs, or small saplings, quite delicate, which fear the intense cold are placed in full sun, with at least a few hours of direct sunlight every day if you live in an area with very cold winters place your mimosa in an area sheltered from the wind, and where it can be easily covered with non-woven fabric in case of intense and persistent frosts.

Watering is the key to having a plant that is always healthy and luxuriant: in fact, mimosas love a cool and slightly humid soil when it dries a lot, you will have to water yourself, especially in periods with mild or hot weather.

They prefer a soil with a slightly acid pH, and from April to September it is good to mix fertilizer for flowering plants with the watering water. Generally, after flowering, a light pruning is carried out, as mimosas tend to develop a very disordered crown as they grow.

Dried flowers

The life of the flowers can be, so to speak, "extended", thanks to the use of drying techniques, which allow the preservation of plants and flowers for a long period of time. The beauty.

Mimosa - Acacia dealbata

The mimosa (acacia dealbata) is a tree native to Tasmania, but which, arrived in our country in the mid-1800s, has adapted very well to the climate of the Ligurian Riviera and that of the regions.

Sensitive - Mimosa pudica

Small evergreen shrub, usually hanging or erect, native to South America. It has thin reddish brown stems, sparsely branched, which bear long f.

Grow mimosa

The term mimosa commonly indicates a shrub belonging to the genus of acacias, in particular the acacia dealbata, whose small yellow flowers are usually given to women during the day.

To prune or not to prune?

Pruning of mimosa it is among the most difficult and must always be light and reasoned.

1. In the juvenile phase the basal branches are eliminated, accompanying the growth of the plant, first shortening them and then cutting them flush to obtain plants with free trunk and defined crown.

2. The bare branches, that is, without leaves, will be eliminated because it is unlikely that they will emit new ones.

3. After flowering, in spring, the branches are shortened and those that are dry, weak or spun are removed.

4. In summer, thinning in subjects with rich and compact vegetation can serve to give light to the internal fronds so that the vegetation over time is not localized only on the outside of the canopy.

Variety of mimosa

Exist different varieties of mimosa, each with very different characteristics and peculiar details.

A very common one is for example the mimosa of the 4 seasons. This typology prefers for example i soils rich in limestone and succeeds in to flourish also many times during the year, from May to September.

There Acacia baileyana Purpurea it produces instead of red colored leaves, really suggestive, as are the orange flowers ofAcacia dealbata Virginia.

If you prefer abundant blooms it is good to opt forAcacia retinoides Lisette, while if you don't like perfume emanating from the flowers you can always choose the variety Acacia cultriformis.

There are also variety of white and pink mimosa in addition to that farnesian, characterized by yellow-orange flowers.

Cultivation techniques and care

As just mentioned, mimosa needs a mild climate to thrive: even if it is a fairly rustic plant that does not require special skills, it fears frosts and excessively harsh and prolonged winters, in the presence of which, the plant would not survive. .

The mimosa in fact prefers a very sunny exposure and in places well protected from the wind.

As for most plants, watering must be frequent, regular and not abundant, in order to ensure that the soil is always humid, while avoiding the danger of stagnation of water, a frequent cause of death from root rot.

Therefore, from March to October, the hottest months, watering will be frequent while during the autumn and winter periods almost nil.The mimosa also fears drought, so care must be taken not to leave the surrounding soil too dry, even in winter months.

The mimosa should be pruned after flowering, an operation necessary especially for those specimens grown in pots.

As for pests and diseases, mimosas are quite resistant shrubs but it can sometimes happen that the plant is infested with mites and aphids.

In these cases it is sufficient to vaporize the hair with water and liquid soap.

Fertilization can be done with both organic and granular fertilizer by dispensing it from March to October. The propagation of mimosa occurs through seed, whose growth speed is remarkable (they germinate in just two weeks). The method of cuttings is not particularly appreciated in gardening, due to the very low percentage of rooting of the cutting.
