From June to July, the fluffy pink blossoms of the mimosa tree (Albizia julibrissin) cover the tree. It’s a good candidate for a specimen tree in a lawn or other open space because of its big, spreading form and vivid blossoms, but it has a number of drawbacks, including litter, weak wood, and a short lifespan.
Identification
In the USDA plant hardiness zones 6 through 9, the mimosa tree is able to survive the winters of a wide range of Asian countries. Butterflies are attracted to the garden by the bright blossoms, but the tree, despite its deciduousness, has no vibrant fall foliage. Because of its fern-like leaf arrangement, this plant possesses bipinnate compound leaves. Invasive mimosa trees should be avoided in locations where they are already present, or in watershed areas where seeds are dispersed by streams.
Rate of Change
At least 2 feet of height are added to the mimosa tree per year, on average. Assuming you haven’t trimmed too much of its height, it can reach its full height of 20 to 40 feet in 10 to 20 years. Flattened and spreading, it eventually reaches a spread of 20 to 50 feet. Though it grows quickly, the mimosa tree survives for just 10 to 20 years at its full height, despite its rapid growth. However, keep in mind that a new one can be planted and will grow to the same height in a short period of time.
Culture
It may thrive in full sun or light partial shade, but it prefers to be planted where it will have the maximum chance of flowering. However, it can grow in a wide range of soils, as long as the soil is well-drained. As a result, it is tolerant of dry conditions and flourishes in the sweltering heat of summer. Mimosa wilt and mimosa webworm doesn’t trouble it, but deer do. It is best not to plant in places where these pests are a common sight.
In the garden,
The foliage, blooms, and pods of this tree are incredibly lovely, but they create a significant amount of garbage. Avoid planting it in areas with a lot of foot activity or where picking up garbage would be a hassle. A short life span and easily broken branches also contribute to its image as an unsuitable tree for landscaping. However, if you enjoy the tree’s appearance and have a spot in your yard where you can plant and observe it, it can be a beautiful addition to your landscape.
It’s time to get the winter mimosas going!
Spring or fall are the optimum times to plant mimosas since they thrive best when they are placed in a sunny, wind-protected area of the yard.
Your deck, balcony, or terrace’s entire area will be filled with the scent of your mimosa tree as soon as the first blooms bloom.
The mimosa tree does, in fact, like shady spots away from drafts, as well as soil that drains well.
- Avoiding thick clay soil is a good idea.
- Flowering mimosa trees grafted onto native rootstocks are best for calcareous soils. As a result, it will perform better in that specific soil type.
- Plant a mimosa tree the right way by following our instructions.
- In the summer, you can propagate your mimosa tree by taking cuttings (highest success rate, but spring is also fine).
- Seeds from trees germinate quickly, so go ahead and collect some.
- Bark can be used to start a new mimosa tree.
Your best bet is to plant your mimosa tree in a large pot so that you can bring it indoors during the winter months in areas where the weather is harsh.
In-pot mimosa flowering

- Mimosa is a shrub that thrives in containers and big garden boxes, but only if the right conditions are met.
- In order for water to drain from the bottom of the pot, it must be devoid of any kind of water holding mechanism.
- The roots will grow faster in a smaller pot.
- Make certain that it is protected from the wind.
- This plant needs sunlight to thrive.
It’s time to repot it in a larger pot after three to four years.
In a container, a soil mix for growing mimosa
Choose a potting mix that is easy to drain:
- Half-and-half flower potting mix and peat for the balance of the sand.
- On top of it, add a couple handfuls of compost.
- Instead of repotting, use a topdressing method if the pot is too large.
Pruning mimosas in containers
Pruning the potted mimosa is more difficult than pruning the ground-based kind.
- After the flowers have bloomed, the pruning process begins.
- Shorten all of the tree’s branches to the desired shape, such as a sphere, cone, etc.
Potted mimosa trees require regular watering and fertilization.
Mimosa bushes in pots require frequent watering since they dry out so quickly.
- Water frequently, but not excessively, to avoid drowning the roots while still ensuring that the soil is consistently moist.
- Fertilize your flowering shrubs throughout their life cycle.
- Alternatively, for nutrients in the spring and summer, apply natural fertilizer every two weeks.
Cold winters and hibiscus trees
If the temperature drops to 23°F (-5°C), the mimosa tree can withstand it. This is particularly true if the freezing spells are brief.
If your tree is planted directly in the ground and the weather freezes hard in your location, follow our tips for keeping plants safe from severe weather.
In the Winter, a potted mimosa tree
If you live in a location where it freezes over the winter, you’ll need to bring your potted mimosa indoors to keep it from succumbing to the elements.
- Wrapping branches in horticultural fleece before the commencement of the first frosts can also be a good idea. You may rest assured that your mimosa tree will not freeze to death.
- In addition, a thick layer of dried leaf mulch should be applied to the foundation to provide further protection.
Winterize your mimosas for at least three years after planting them in the ground. If you’ve already brought it indoors for safety, this is very vital. For the first three “outside winters,” the tree’s natural defenses will gradually strengthen, allowing it to withstand the cold on its own.
Mimosa pruning and care
The mimosa tree requires little attention once it has established a strong root system. Just be careful not to have a hard freeze on the blossoms of an already blooming mimosa tree at the last minute.
Apart from that, the mimosa is so vigorous that it has earned the moniker “intrusive.” But don’t worry: frequent pruning and care will keep it under control.
How do you cut down a mimosa tree’s branches?
It’s impossible to get any flowers from a mimosa tree if you prune it in winter, which is when the tree is dormant.
- Cut back the branches that have produced blossoms.
- Pinch suckers from the trunk as soon as they appear. At ground level, they’ll weaken the tree’s other branches.
For branches that have been damaged and discolored by freezing at the end of winter, you are free to take them off because they would also weaken the tree.
It’s hard to say just how quickly a mimosa tree grows.
In a single season, a single shoot can grow up to 5 feet (1.5 meters)!
- There will be more side branches coming out of this shoot in the next season.
To get a low-growing, bushy shrub, use this method.
- Snip each branch when it reaches a height of two feet or less (50 cm).
- A dense, spherical shrub covered in blooms will form as a result of their growth.
- This can be done at any moment, regardless of the day or time.
- Also, if you need to dramatically lower the tree’s size, feel free to do so. Mimosa is able to handle a lot of pruning.
A lofty, tree-like form is what you’re going for.
- Allow the highest stem to grow as it pleases.
- The trunk’s side suckers should be removed.
- If you want your “trunk” to be taller, remove suckers to that height.
- A tree-like crown will begin to appear above this point as branches begin to spread out and flourish.
Even if the trunk of the mimosa is completely frozen over, it will regrow from the ground up. Depending on how you want to shape your tree, you may want to give the new sucker some time to establish itself.
Always use a smaller branch soon after a split or y-junction when pruning your tree. Pruning slightly above a bud that can take the lead and grow is another option. In order to avoid hatracking your tree, you’ll need to be careful.
Taking care of a Mimosa tree that needs watering
Except when it’s in a pot, mimosas don’t require much watering. Excess moisture, on the other hand, will eventually kill the tree since it will cause the roots to rot.
Taking care of a newly planted mimosa tree
- You should only water the mimosa tree if the weather is exceptionally dry; otherwise, the tree’s own reservoirs of water should be sufficient to meet the plant’s needs.
Potted mimosas need watering
- A reasonable amount of watering is necessary for potted mimosas during winter. When it’s not frigid, it’s fine to give it out.
- Water in the evening throughout the summer and during hot weather to avoid water evaporation.
The most important things to know about the mimosa tree
Florists sell Mimosa in January while the blooms are still in buds, and it is already fragrant enough to fill a whole house with its aroma!
Its flowers have a pleasant scent and are covered with evergreen foliage.
It is a tree that blooms in the winter and is prized for the color and fragrance of its flowers as well as the length of time that they bloom.
It’s during the coldest, darkest days of winter that this tree bursts into vibrant color and fills the area with the delightful scent of spring.
In a large garden box, you may also enjoy the benefits of this tree on your terrace, balcony, or deck. Once the earth has become completely dry, all that’s required is a quick sprinkling of water.
Acacia and Mimosa are two different species of tree, yet they’re often used interchangeably. Acacia is the proper name for the latter, while Mimosa refers to the former. The silk tree, Albizia, is another common name for a mimosa in the United States.
A better understanding of the various acacia tree varieties.
There are over 1200 species of mimosa trees in the world, and they were first introduced to Europe along the Mediterranean coast and then the Atlantic coast. Since then, they’ve made their way over the temperate regions of the world.
The advice concerning the mimosa tree is a good one
Adding fertilizer to a mimosa tree after planting is unnecessary because it never needs it. Growing mimosas in pots is an exception to this rule, as the soil must be refilled.
Water will not evaporate and weeds will not grow with a simple layer of mulch.
If you prune your mimosa tree frequently, it will remain a small tree, but if you let it develop, it can become a large tree.
