How to root a mimosa tree

Mimosa Propagation | Home Guides

By Maureen Malone Updated August 01, 2022

The mimosa tree (Albizia julibrissin), also called a silk tree, is native to Asia and known for its showy blooms. Mimosa plant propagation can be done by seed or root cutting. The trees grow in U.S. Department of Agriculture plant hardiness zones 6 to 9.

Mimosa Plant Seed Propagation

Mimosa trees will grow from seed, and the trees produce an abundant amount of seeds. The tree produces pods that are 4 to 8 inches long, and each pod contains five to 10 seeds, advises North Carolina State University Cooperative Extension. The seed pods turn brown and mature in the late summer and fall months from August to September. Yates recommends harvesting the seeds in the fall and storing them in a cool, dry, dark location over the winter months. You can also purchase seed packets from a nursery if you decide to learn how to start a mimosa tree from seed.

Before you sow seeds, they need to undergo scarification. There are a couple of ways to achieve this. Use sandpaper to file through the seed coat and then soak the seeds in water for 24 hours, advises Sheffield's Seed Co. You can also cover the seeds with boiling water and leave them to soak for 24 hours.

Sow the seeds in the spring after the danger of frost has passed and the temperatures have risen to at least 59 degrees Fahrenheit, advises Fine Gardening. Plant the seeds 1/8 inch deep and water as needed to keep them moist until they germinate.

Mimosa Plant Cuttings

Can you start a mimosa tree from a cutting? These trees can be propagated from root cuttings, but stem cuttings won't root. Take a 2- to 6-inch root cutting from the plant in the winter months. Keep track of the orientation of the roots so that you know which end was near the crown of the tree and which end was growing down into the soil.

Take the cutting from a healthy tree that is ideally two or three years old. Place the cuttings in a moist medium, such as peat moss or sand, and keep them at a temperature of 40 degrees Fahrenheit, recommends the North Carolina Extension Gardener Handbook.

Root the cuttings in the soil when temperatures warm. Make sure the cutting is oriented correctly and that the top of the cutting is at a depth of 2 to 3 inches. The soil should have excellent drainage so that the roots don't rot. Water regularly to keep the soil moist.

Growing Mimosa Trees

Plant the mimosa tree in a location with full sun to part shade. The plants are tolerant of a wide range of soil types from sand to clay and grow in a wide range of soil pH levels, including both acidic and alkaline soils. Mimosa plants are tolerant of heat but should be protected from strong winds and heavy snow and ice accumulation that can damage the plant's weak branches.

Consider carefully before adding these plants to your landscape. Despite their beautiful appearance and stunning blooms that attract butterflies and hummingbirds, there are several problems to consider. The plant can be invasive in some locations as it spreads easily by seed. The seeds can cause a significant litter problem, and you will need to devote time to cleaning up after the tree. This is especially true if you have dogs or livestock, as the seeds contain a harmful neurotoxin.

Short Guide on How to Grow A Mimosa Tree From A Cutting

Mimosa trees grow extremely fast. They’re also pretty easy to nurture for anyone; even amateurs. With correct techniques, you can easily propagate a mimosa tree. 

How to grow a mimosa tree from a cutting? 

Start by taking a proper stem from a mimosa tree. After that, remove some leaves and dip them wet in the water. Prepare the pot with soil in the meantime. Place the stem in the rooting hormone powder before placing it in the soil. Wrap it in a plastic bag and keep it in a sunny room. 

That was just a short version of the whole process. I have elaborated on every step and explained it as much as possible in the article. 

Keep reading if you want to know more about the propagation of mimosa trees!

Everything You Need To Know Before Trying To Grow Mimosa Tree

You can’t just grow a tree anywhere and anytime! Plants require care as much as pets and humans. For plants, there is specific weather and other conditions.

That’s why having prior knowledge before dealing with trees is important. It applies to growing, nursing, and everything else!

For example, saving a dying ficus tree requires some specific methods. And without that, you won’t succeed! Growing Mimosa trees are also the same. 

The mimosa tree or Albizia julibrissin is one of the fastest-growing trees. These trees require only 8 years to grow completely. They reach 40 to 60 feet upon hitting full maturity. 

But there is a condition that you need to know about. It’s the plant hardiness zone. This scale indicates a plant’s survivability based on temperature. 

The USDA scale puts mimosa trees in zone 6 to 9. It means in these zones you don’t have to worry about the tree’s survival. 

Likewise, you don’t need to worry about chamomile propagation inside zone 3 to 9! 

But to save you some time I have listed some US states under zone 6 to 9. Here’s what you’re looking for:

USDA Plant Hardiness ZoneTemperatureThe Notable US States
Zone 6 (Colder)Lowest: -10 °F or -23. 3 °C 
Highest: 0 °F or -17.8 °C
Arizona, Kentucky, Kansas, Nevada, Northern New Mexico, Ohio, Washington
Zone 7 (Cold)Lowest: 0 °F or -17.8 °C
Highest: 10 °F or -12.2 °C
Central Arizona, Eastern California, Southern Nevada, Southern New Mexico, Southern Oklahoma, Northern Texas, Southern Utah
Zone 8 (Warm)Lowest: 10 °F or -12.2 °C
Highest: 20 °F or -6.7 °C
Alabama, Arkansas, Arizona, California, Florida, Georgia, Louisiana, North Carolina, Oregon, South Carolina
Zone 9 (Warmer)Lowest: 20 °F or -6.7 °C
Highest: 30 °F or -1.1 °C
Southern Arizona, Northern California, Florida, Louisiana, Eastern Texas

These were all the US states where mimosa trees will survive. If the temperature doesn’t drop below -10 °F, you’re pretty much good to go. 

Mimosa Tree Propagation in 5 Simple Steps

Whether you’re propagating or moving a tree without killing, you’ll need a specific plan. Without it, you’re bound to make mistakes and they’ll prove to be fatal later. 

Fortunately, growing a mimosa tree from a cutting is easy enough. You can do this any time of the year. But late spring is the best time to do it! 

To make it even easier, I’ve explained the entire process step by step-

Step-1: Select a Proper Mimosa Tree Cutting

First, you’ll have to cut a stem that is 4 to 6 inches in length. It also has to be firm in nature. 

Simply pick a spot where leaves are supposed to emerge from. Cut the area which is just below your chosen spot. 

Step-2: Prepare the Stem & Soil Pot 

It’s now time to pick a pot. Fill a pot with 4 inches of soil. It has to be well-drained. Water the soil until it leaks through the draining hole. 

Remove all the leaves from the stem except for some at the top. After that, take a glass of water and dip the part that you cut. 

Take out the excess water and you’re done!

Step-3: Put the Cutting in Rooting Hormone Powder

Rooting hormone is a special powder chemical that increases root growth. By doing that, it increases the overall rate of success in every propagation.

The Mimosa root system is similar to the root system of pine trees. Both of them have taproots that benefit from rooting hormones! 

Luckily, you can easily get it from your nearest store. You can also order it online!

To save you some time, I have listed some of my top picks:

Product 1
Product 2

Simply pick whichever you like more and it’ll be sufficient. 

Take a bowl and pour some powder into it. Place the wet stem into the powder. Make sure the powder touches every bit of the cutting area. 

Afterward, take it out and get rid of excess powder. 

Step-4: Place the Cutting In the Soil & Position It Properly

Place the cutting nicely in the soil. Make sure the soil around the cutting is firm enough. Afterward, take a plastic bag and shut it tightly. 

Take the pot and position it where it’s sunny. But remember to avoid direct contact with sunlight. The ideal temperature for this process is 75 °F or 23.8 °C. 

Check the pot daily and keep track of the cutting. 

Step-5: Test the Roots (After 3 Weeks) 

It’s time to check the roots of the cutting. For that, you’ll need to pull the cutting. Do it as gently as possible. 

If you can pull it really easily, the roots aren’t there yet. On the other hand, if you feel resistance, it’s because of the roots. 

Remove the plastic bag if the roots have been formed. Keep it in the pot for two more months. Afterward, transfer it to a bigger pot which is at least 1-gallon. 

It will continue to grow bigger for about another year or so. When it has grown enough, plant the mimosa tree in a place of your choice. 

Additionally, if you have a podocarpus and want to it grow faster. There are ways for that too but you just have to follow the rules and be patient with it.


Question: How do you grow a mimosa tree indoors?

Answer: Mimosa tree doesn’t require direct contact with sunlight. But it does require a sunny room all day. Otherwise, it won’t thrive properly. Just pick a sunny room and keep the soil moist. 

Question: What are mimosa trees good for?

Answer: Mimosa tree barks are quite important in Chinese medicine. It’s also believed to be a spiritual cleanser and good against depression and anxiety. If you’re an insomniac, you’ll get some benefits too. 

Question: Is mimosa tree poisonous to dogs?

Answer: Mimosa trees aren’t exactly poisonous but the seeds are. They’re super toxic towards the animals and children. If you’re growing some mimosa, keep the seeds in a secure place. 

Final Words

That was everything on how to grow mimosa trees from a cutting. I hope that this has cleared the confusion that you were having. 

One last thing before you leave us. You can always call experts and ask for their advice if you’re still confused. They’ll be glad to be of help.  

Finally, have a nice day!

How to save a bouquet of mimosa and grow it yourself


Admin - Aigul Sharifullina, March 3, 2020 - 19:04

Mimosa is the main decoration of the main spring holiday on March 8. On this day, all Russian women receive beautiful fragrant yellow bouquets. Everyone knows the symbol of the women's holiday, but not everyone knows the features of the growth of mimosa. Proper maintenance of the flower at home will keep it fresh for several weeks. If desired, and in a certain climate, the plant can be grown independently in the garden.

In what climate does it grow better

The question of where mimosa grows becomes relevant not only on March 8, it is asked by gardeners who love this amazing plant. Initially, it grew only on the island of Tasmania. Gradually, the tree moved to the nearest countries, and from there it reached Russia.

The natural climate for the plant is warm and humid. In the Australian heat, mimosa grows to the size of a full-fledged tree, but in regions where it is not so hot, it stops at the size of a shrub.

Growing regions in the Russian Federation

You can meet a small mimosa in Russia on the Black Sea coast. In the local climate, it grows only up to 12 meters and is a shrub.

A shrub grows in such regions as Sochi, the Caucasus, Abkhazia.

Initially, in Russia it was a cultivated ornamental plant that adorns parks and alleys, but now mimosa has spread so much that it has become a wild weed.

In the world it is found on the island of Madagascar, in France, Montenegro, on the west coast of America and in Brazil.

Cut by March 8th

In Russia, the plant begins to bloom from February to March. This is due to the fact that mimosa was brought from the southern hemisphere, where summer is in these months. If the winter in the region is warmer, then the tree may bloom in January-February. In the coldest regions, the flowering of the plant occurs in September-October. By March 8, mimosa is cut at the end of February, when it has not yet opened.

Transport and storage

Only twigs with closed buds are transported, otherwise they will not reach their destination. Before transportation, the branches are cooled and packed in a special film and cardboard boxes.

Subject to all transportation rules, mimosa can be transported for no more than 48 hours. After that, it will need water and begin to dry out. If it is impossible to comply with these rules of transportation, 24 hours are allotted for it. That is why mimosa is not taken to areas remote from the Black Sea.

Before selling, the sprigs are stored without water in the cold so that they do not deteriorate and do not open ahead of time. You can sell them on the street, they are saturated with moisture from melted snow, and the low air temperature will not allow the buds to open.

Can I grow my own

The plant can be grown on its own in a pot at home or in the garden, if climatic conditions allow.

A tree is grown from seeds or cuttings. A low tree grows at home, the planting of which usually occurs in January. Domestic mimosa blooms 2–3 years after rooting, subject to at least 60% humidity and + 25 ° C. Such conditions are considered comfortable for growth and development.

Seedlings purchased from nurseries or botanical gardens are planted in the garden. A tree can only grow in a warm and humid climate, so you should not try to get a mimosa for a summer cottage in a region with harsh and snowy winters.

Tips for keeping the bouquet fresh

If you just bring the bouquet home and put it in water, it will live for about 4 days. A few tricks will help keep mimosa much longer.

Freshness tips:

  1. Cut off the lower leaves.
  2. Pour hot water over cuts.
  3. Add aspirin to water.
  4. Mix 2 tsp. sugar and coniferous extract and add to water.

Instead of aspirin, you can add 50 g of vodka or alcohol to disinfect it.

In order for mimosa to please for a long time, you need to place it in a warm and bright place. Before buying, you need to smell the bouquet, if it has a bright aroma, then the flowers did not lend themselves to any processing and are fresh. Do not put them with other colors, as they will fade quickly. To enjoy mimosa until next year, it is enough to dry it, leaving it without liquid after 3 days in water.

Mimosa: planting, care, reproduction, partners, landscape use, pests and diseases

Almost every one of us from childhood knows silvery twigs covered with small yellow balls-flowers, which smell pleasant and symbolize the approach of the women's holiday. It is these associations that cause mimosa - a plant that is offered at retail outlets on the market. Although the plant is not so simple.

In fact, a real mimosa, whose homeland is called Australia and Tasmania, successfully grown in South Africa and America - in our climatic zone can only be grown in warm greenhouses. After all, the plant in question grows in open ground only in warm subtropical and tropical countries. And those fragrant branches, familiar and very beautiful, offered by retail outlets in the form of mimosa, are not mimosa at all, but its heritage, thanks to breeders, completely acclimatized in our cold and humid climate, retaining the external signs of the mimosa mother plant - Silver Acacia. It is this flowering perennial that is grown on the shores of the Black Sea and the Caucasian coast.

From here cut products are supplied to the flower markets of countries with moderate climatic indicators, where real mimosa does not grow. But the eucalyptus forests of the subtropics, the shores of forest lakes and shallow rivers seem to be sown with bushy and woody plants with fluffy racemose inflorescences.

Description of mimosa or Acacia silver

Acacia silver belongs, like the mother plant, to the leguminous family, just as beautiful, powerful and evergreen.

In appearance, it is a mighty tree, up to 10 m high with a powerful and spreading crown - such specimens are grown in the Yalta Botanical Garden. Or Acacia is silvery, like a shrubby, two or three-meter plant, which tolerates temperature drops only to minus 10 degrees and grows in colder areas. Very small, almost miniature bushy plants are also possible, which can be grown as indoor flowers, the height of the main stem is up to 30-40 centimeters.

  • The appearance of the leaves of all representatives of Acacia silver is the same, only the sizes differ. On long branches there are pinnately dissected leaves, which, not having time to blossom, are covered with a gray-green bloom, resembling silver in the sun. Thanks to this feature, the acacia was called silver.
  • Among the silvery leaves, the plant produces panicle flower inflorescences, which eventually become covered with fluffy bright yellow balls exuding a pleasant aroma.
  • More than 30 small flowers can be counted on one flowering raceme, the diameter of the largest inflorescence is up to 1 cm, but the average is much smaller. Balls in appearance resemble small dandelions and are able to hide a branch and not at all expressive foliage under them. Whether it's a tree or a bush - from a distance, the Silver Acacia is very similar to a large balloon.

Flowering and fruiting period

The plant blooms for the first time after planting only in the second year of growth, flowering continues from the end of winter until April. After flowering, the plant sets fruits - bean pods, long and dense, pale brown in color. In the middle of the pod, dark brown, oval-shaped seeds are formed, up to 5 mm long. Fruiting and ripening of seeds occurs in September. At this time, the seeds from the pods are ready for germination in order to propagate the plant.

Scope of use

Distinctive in Acacia silver and purpose plants. If indoor specimens serve to decorate the home. Greenhouse species, both trees and shrubs, are grown for cutting and sale. That gum, which is formed on the trunks of large trees, or rather in natural cracks in the trunks, is used both in industry and in medicine.

Feature of the plant

Silver acacia, like its close relative - southern mimosa, have one amazing feature. The plant can respond to any touch or mechanical damage with its appearance. Rather, the shape of branches with needle-like leaves. As soon as the plant “feels” the slightest touch of a foreign object, the branches will fall down, and the leaves will fold along the branch. So the plant reacts to touch and to the change of day or night. At night, the leaves on the branches are folded, and with the onset of the morning they straighten out and become fluffy. Knowing about this feature, you should not experiment at all - the plant does not like outsiders and will quickly lose its strength and power.

Secrets of successful cultivation of Mimosa or Silver Acacia

There are a number of points and nuances that must be taken into account in order to achieve successful cultivation.

  1. Heat and light. When growing a plant in a personal plot, it is necessary to choose a well-lit and warm place in the garden, where there are no drafts and midday shade. When grown in a greenhouse or room, large southern windows are quite suitable for the plant. In winter, plants are provided with additional illumination, which will give both warmth and light. In low light and low, cool indoor temperatures, the plant will not bloom. In the summer heat, flowerpots are taken out to the terrace or balcony - fresh air is also useful for a flowering plant.
  2. Temperature indicators. Mighty silver Acacia trees grown in the warm conditions of the Crimean coast can easily withstand frosty weather. The thermometer should not fall below minus 10 degrees. When growing indoor plants or keeping them in greenhouses, the main requirement for acacia or mimosa is warmth and comfort. Room temperature of 20-24 degrees is quite acceptable for growing a perennial plant.
  3. Watering frequency. Moisturizing the soil cover, even in the garden, even in a pot, must be done as the top layer dries up. Watering is done twice a week in the summer. In winter, watering in the garden is not done. Indoor plants are watered regularly, avoiding waterlogging of the soil and stagnation of water at the roots.
  4. Air humidification. In the garden, of course, large trees, or rather, the air around the plants do not moisten, the trees themselves cope with the arid climate. In greenhouses and rooms, special humidifiers can be set up, but it is not necessary to spray the crown of shrubby acacias.
  5. Fertilizing. The application of nutrients, organics and mineral fertilizers must be done in spring and summer with a certain sequence. In winter, dormant plants do not fertilize.
  6. Planned cutting. Big size woody plant of Acacia silvery or shrub – need timely crown formation, ie pruning. The plant grows young shoots especially abundantly in the spring and summer. Old and young branches are able to bloom, but the bush becomes very dense, which has a bad effect on further growth and development. Therefore, after the end of the flowering period, excess, old or diseased branches leading to thickening are cut out, thereby freeing the tree from excess mass and thickening. Conclusion, the pruning process not only allows you to correctly form the crown of the plant, but also facilitates the breathing of woody shrubs, provides unhindered access to oxygen. Old, but still suitable, necessary for the tree, in your opinion, the branches are shortened by half the length, the young shoots are cut by one third.
  7. Soil mixture and its composition. Fertile, loose and breathable soils of the garden plot are quite suitable for growing our mimosa. When planting young seedlings, soil mixtures are used from garden soil, forest turf, humus and sand. Garden soils with the addition of additional nutrition in the form of mineral fertilizers and humus compounds, or plant substrates purchased through retail chains, are quite suitable for growing indoor plants.
  8. Transplantation. For better development of the root system and growth of deciduous mass, as well as replacing the soil substrate with a new one, and the container with a more spacious one, breeders recommend transplanting two and three-year-old seedlings of indoor mimosa representatives to a new growth site. Younger seedlings are transplanted once a year until the plant is fully grown and blooms, and the size of the flowerpot is fully consistent with the size of the grown crop. Transplanted young plants only after flowering. Mature shrubs can be transplanted after two to three years. If your plant no longer needs to be transplanted, then at least replacing the top layer of soil in the flowerpot is still necessary.

Propagation of mimosa

Mimosa or Silver Acacia are propagated in two ways: with the help of seeds and cuttings.

  1. Seed propagation. Seeds a year old are suitable for growing the plant. Before sowing, and it is produced at the end of January, they must be disinfected and germinated in warm water until small sprouts appear. The seeds usually germinate after two days. In the prepared soil substrate, the seeds are laid out to a depth of 3-4 cm, the crops are moistened and covered with earth. The container can be covered with glass or plastic wrap to create a greenhouse effect and rapid germination. Seeds germinate within two to three weeks. When the first leaves appear from the ground, they grow well and get stronger - the seedlings dive into separate flowerpots by transshipment. Seed propagation is used mainly for houseplants Silver Acacia.
  2. Cutting method. Cuttings from the mother bush are suitable for cutting and forming a new plant in the spring, before flowering, or in late summer, when the shrub tree has already faded. You can cut the apical cuttings from healthy branches or germinate the shoots obtained by pruning and thinning the crown of a tree or shrub. Prepared cuttings must be placed in a moist and nutritious soil substrate, where they will form and grow roots. Cuttings need heat, light and water, therefore, greenhouses or greenhouses are needed to obtain seedlings by cuttings. The temperature in the room should not be below 24 degrees Celsius. The period of rooting of the cuttings lasts about two months.

Diseases and pests of mimosa

Silver acacia, or, more familiar to us, mimosa, is a living plant and is subject to almost all diseases that affect both garden and indoor plants. Fungi and viral bacteria can settle on untreated sections of apical cuttings, on foliage and young shoots. The cause of plant disease can only be improper care and violation of the requirements of agricultural technology, which were described above.

Pin : spores of septoria, brown rust, peronosporosis, gray rot and alternariosis, fusarium and soot fungus living in moist air and soil lead to decay of the root system and deformation of the deciduous crown. The leaves curl, change color, dry out and crumble. Stems and shoots are deformed, broken. Flowering does not occur, the plant does not develop.

Special insecticidal mixtures, phytopreparations, laundry soap, activated carbon, soda, brilliant green and iodine, as well as solutions of manganese and furacillin will help to overcome fungal and viral infections. The main thing is to detect signs of the disease on the plant during the time and start spraying and removing the foci of the disease.

Quite often, branches are entangled with a barely noticeable web that can change the color and integrity of the leaf plates, which, for a seemingly incomprehensible reason, begin to crumble. So, a spider mite has settled on your mimosa.

Or there is a sticky, sugary coating on the branches and leaves, which is secreted by small black bugs. The plant is subject to the invasion of aphids, which, by sucking the juice from the branches and leaves, will completely destroy the woody shrub. Only timely spraying will help expel insect pests from a flowering bush.

A change in appearance - a signal of improper maintenance and care

When growing any plant in an open field garden, greenhouse or on a windowsill in a residential apartment, a novice flower lover will definitely notice changes in the appearance of his pet, if something went wrong. The plant signals the owner about errors in the content. Namely:

  • a scattering of flowering buds around the plant indicates a lack of moisture and dried soil;
  • limp, lifeless leaves indicate either excessive watering or drought. Leaves wither, crumble and from heavy soil;
  • pale and discolored leaves of the plant may appear when there is a lack of light. A change of location or an additional light source is needed;
  • brown foliage indicates dry air and low moisture;
  • leaves with dark spots - low temperature or draft.

Mimosa in landscape design

Landscape design is a special area where everyone can experiment, give free rein to their imagination in combining plants, when creating their own flower garden or territory.
