Many people associate the flowering of mimosa with the arrival of heat and the onset of spring. It is she who begins to offer in retail outlets for International Women's Day. Bright yellow balls on delicate branches look very touching against the background of the snow that has not yet melted. Let's take a closer look at the process of growing this amazing crop.
Peculiarities
This plant belongs to the legume or acacia family.
There are more than 350 varieties of mimosa, according to some sources, their number can reach up to 500.
The main difference among them is the flowers . They are very fluffy, yellow, pink or creamy.
What does it look like?
This plant is considered to be an evergreen perennial. As for the description, this shrub is capable of reaching 40-60 centimeters in height, and in some cases it grows up to one and a half meters or more. Mimosa can also be called silver acacia.
Its appearance is extremely pleasant. On the bush are neat, not too large branches. They have small leaves that look like fern leaves, and the inflorescences form panicles. The plant is covered with small flowers resembling fluffy balls, mostly of bright yellow color.
Florists note a delicate herbaceous scent . It lasts for a long time even on cut flowers. The pollination process can take place both with the help of the wind and with insects. Mimosa blooms for about 4 months, and after that the twigs are decorated with fruits hidden in the pods. Each pod can contain 2 to 8 beans.
The main feature that distinguishes mimosa is its ability to fold the leaves when touched. The plant looks wilted, but after half an hour or an hour, the leaves open again, taking on the same appearance.
Finding out the origin of this feature, scientists came to the conclusion that the reason was the climatic conditions in the natural environment of the plant.
These areas are characterized by tropical showers, and the folding of the leaves helps the plant to defend itself. However, such a reaction can not be observed in all species - most often it is noted in bashful mimosa.
I must say that the life rhythm of mimosa corresponds to 22-23 hours . After that, the culture seems to fall asleep, folding the leaves. After rest, they open up again. Moreover, daylight hours in this situation does not play any role.
Is it a flower or a tree?
Novice growers often wonder if mimosa is a flower, tree, bush or grass. I must say that the culture is of Australian origin and belongs to evergreen shrubs … Despite the fact that it can reach a considerable height, it would be wrong to consider this plant a tree.
Where does it grow?
Before considering the question of the place of growth, it must be said that the culture was brought from Australia. She appeared on the island of Tasmania . It is there that the most favorable climatic conditions for mimosa, suggesting not only warm weather, but also significant humidity.
At first, mimosa spread throughout Africa, Asia and the United States of America. In our country, it appeared towards the end of the 19th century.
The best place for the growth of this culture is the Black Sea coast . It can most often be found in Sochi, the Caucasus and territories close to Abkhazia. There, mimosa can grow almost everywhere, and the specimens are quite large.
Types and varieties
Mimosa is presented in several hundred varieties - bashful, Chinese, muffled and others. Most of them originated in South America. A number of species originate from Australia, Asia and the African continent. Let's consider the most popular ones.
Mimosa bashful, perhaps, can be considered the most famous. This perennial plant originated in South America, but today, due to its attractive appearance and decorative properties, it is distributed throughout the world. The height of this variety can be from 50 centimeters to one and a half meters. The stem is prickly, and the branches of the bush are fluffy and straight.
The leaves of the bashful mimosa are pinnate and oblong. They are covered with fine hairs, due to which they are very sensitive, which makes them able to react to any touch by curling up. Small balls of flowers can be either yellow or purple with pink tints. The inflorescences are racemose.
The stamens protrude from the corolla, giving the impression that the flower looks like a fluffy ball peeping out of the apical sinuses of the foliage. When the fruiting period comes, the bush is covered with beans, each of which contains 2-4 pairs of seeds. The plant is pollinated by insects or with the help of the wind . Bashful mimosa blooms from June to August. If you grow this variety at home, it should be done as an annual.
Cultivation takes place in many tropical areas. Wet thickets are the most comfortable for the variety.
The plant is very common in different countries, it can be both indoor and grown in greenhouses.
The next popular variety is muted mimosa . It grows very quickly and can reach a height of 8 meters. The trunk is quite dark, can split, and the wood itself is very dense. The variety originates in Brazil, but is also found in Mexico. It is often used to make psychoactive concoctions. Most often, this shrub is located at low altitudes, but it can also be distributed at an altitude of 1000 meters above sea level.
The leaves, like most plants of this species, resemble a fern. They are feathery and grow up to 5-6 centimeters in length. The flowers are white in color and have a delicate enchanting scent. Inflorescences resemble cylinders in shape, their length is from 4 to 8 centimeters. In the southern regions, the period of flowering and fruiting falls on September - January and February - April, respectively . In the northern territories, the process begins in November and ends closer to the middle of summer.
The fruits are about two centimeters in size . They are quite fragile and contain 4-6 oval seeds. It is good to plant other plants next to muted mimosa, as it perfectly conditions the soil, achieving nitrogen fixation.
Rough mimosa also appeared in South America. It is distinguished by snow-white flowers gathering in panicle-shaped inflorescences.
The variety is very delicate, looks cute and unusual.
Mimosa lazy it is primarily used by flower growers as an ornamental perennial shrub. It has both straight and branched shoots. The average height of such a plant is about half a meter. The capitate inflorescences are formed by fluffy snow-white flowers. The leaves are very sensitive due to the presence of villi. They are fern-shaped and fold quickly when touched.
Mimosa feline is a spreading shrub with a height of 1 to 2 meters. There are thorns and sensitive hairs on the shoots. The plant has small leaves and white or white flowers with a pink tint, similar to small balls. The fruits are pods about 4 centimeters in size. This variety is widely represented in Arizona and New Mexico, northern Mexico and Texas.
Growing conditions
This plant can be grown both in the country or on the site, and in indoor conditions. Despite the fact that it looks very gentle and touching, flower growers note its unpretentiousness. Mimosa is very thermophilic, the ideal temperature for it is from +20 to +24 degrees in summer and + 16 … 18 in winter . The minimum temperature in winter must be at least +10 degrees Celsius. In addition, she needs a sufficient amount of light, even direct sunlight will not be a problem. However, in the case of growing a flower in a pot, it will still need to be periodically removed from the sunny side in partial shade.
Mimosa needs fresh air, but at the same time it is necessary to protect it from drafts . This is especially true in a house where people who smoke live. The plant does not tolerate tobacco smoke and quickly sheds foliage. For the same reason, it cannot be placed in the kitchen.
The soil
It is necessary to plant mimosa in open ground in the sunny part of the site, using loose soil. The place should be protected from drafts and sheltered from gusts of wind. After planting, you need to constantly water the plant until it becomes clear that it has taken root completely. No pruning is needed here. An established plant will require minimal care when it is provided with comfortable climatic conditions.
As for the soil itself, you need to take care of the correct composition . A mixture of turf, humus, peat and river sand, taken in equal proportions, is considered optimal for mimosa. The bottom of the planting hole is laid out with expanded clay, which will provide good drainage and protect the roots from excessive moisture. If we are talking about a perennial, it will need to be transplanted in mid-spring. And you should also regularly loosen the ground and weed the landing site.
Location
Despite the fact that mimosa as a species originates from the tropics, the optimal location in most territories of our country will be a house, a greenhouse or a winter garden … In another situation, the plant should be considered as an annual, because in the fall it will not look too neat due to the highly elongated shoots.
If the winter in the region is rather mild, plant the mimosa in a well-lit place.
If this condition is violated, its appearance may not be very attractive, in addition, it may not bloom at all … Do not arrange a flower garden on the south side, as this can threaten the leaves with burns. At first, the territory will need to be shaded, which will save you from this trouble.
How to care?
As already mentioned, home-grown mimosa is often one-year-old. The greenhouse can provide the most natural conditions. We are talking about light, temperature and humidity levels. This allows the flower to grow there for a longer period of time.
As for indoor flowers, they also need good lighting . Ideal would be placement on a window facing south, west and east sides are suitable. However, on the hottest days, when the sun is especially active, the plant will need to be removed in the shade for 2-3 hours, otherwise burns may form on the leaves. This is also the reason why mimosa needs to be accustomed to sunlight gradually.
General care is easy. For example, crown molding is at the discretion of the grower and is not a prerequisite. However, when it comes to perennial shrubs, experts still recommend shortening especially long shoots. With sufficient light, the flower will quickly make up for the loss.
If the flower grows at home, you will also need to monitor the temperature regime . From March to the end of spring, it should be within + 20 … 24 degrees. In winter, the optimal performance should be kept at around + 15 … 18 degrees Celsius.
Watering is an important factor. It should be done regularly and fairly abundantly, especially on hot summer days. For humidification, use settled, not too cold water.
If the plant is in a pot, the tray should always be filled with water. Mimosa is watered in the morning or in the evening, when the top layer of the earth dries out a little.
Sprinkle with mimosa in spring and summer. A conventional spray bottle is suitable for the procedure. You should not get water on the flowers themselves. To ensure the required level of humidity, a regular container of water will do.
And also do not forget about fertilization. This issue is especially relevant during the period of active plant growth . Special mineral complexes are perfect. Top dressing is added 1 time in 1, 5-2 weeks.
No transplant is required for an annual plant. In cases where it needs to be carried out, you must be as careful as possible with the root system.
Reproduction methods
Inexperienced growers are often interested in how a new mimosa bush can be grown. This is done using seeds or cuttings. Let's consider these methods in more detail.
Growing from seed can be repeated every year . The material is sown at the very beginning of spring. It must be buried 5 millimeters into a soil mixture containing sand and peat, and then covered with polyethylene. The temperature favorable for the procedure is about +25 degrees Celsius.
It is necessary to dive for mimosa when the first shoots appear, and each of them has a couple of leaves . It is necessary to prepare containers with a diameter of 7 centimeters, where 2-3 seedlings are placed.
Sod and leafy soil are used as a soil mixture in equal proportions, as well as half the amount of river sand. You can purchase a special formulation in the store.
When the root system fills all the space provided to it, the mimosa, along with the earthen lump, needs to be carefully transplanted. Disembarkation to a permanent place is carried out in warm weather 2-3 months after landing. Further transplants should be discarded.
The grafting process is a little easier . The procedure is carried out in the spring or at the very end of summer. Cuttings are cut in July or August, after which they are planted in a container with peat and sand, then covered with a container made of glass or plastic to ensure the required level of humidity. When the soil dries up, it will need to be moistened. And also you can not do without regular ventilation.
If offspring appear at the base of the stem, they should be cut off with a sharp knife in order to be used later for cutting cuttings. The plant takes root in 2-3 months, after which it is planted in a permanent place.
Mimosa reproduces equally well in any of these ways . Which one to choose, the florist himself must decide.
Diseases and pests
Regardless of where the mimosa is grown - in an apartment or in the open field - there are a number of troubles that can hit it. If we talk about pests, this perennial aphid and spider mite are attacked first of all.
Aphids are very small green or black pests. They cover the leaves with a sticky bloom. Ticks, on the other hand, entangle the inside of the leaves with a thin cobweb, and also suck out the juice.
In each of the cases, it is necessary to spray the mimosa with insecticides, repeating the treatment after a week.
It is very unpleasant for a plant to be attacked by a pest such as a mealybug. Getting rid of it will take time and effort. The shrub is processed with a cotton pad, which must first be moistened with alcohol. And you will also need an antioxidant agent.
Mimosa can get sick . The lack of moisture usually leads to yellowing and wilting of the leaves. With irregular watering, the greens will fall off. Excessively rainy weather is not too favorable - it will not allow the leaves to open in the daytime, which will lead to their yellowing. Too strong shade threatens to lack flowering. And also this factor can be influenced by too much decrease in air temperature.
