How to prune jacaranda tree

Plant Care & Growing Guide

The jacaranda tree (Jacaranda mimosifolia) is a beautiful tropical tree that produces clusters of fragrant purple panicle-shaped blooms. Jacaranda branches are arched, forming a canopy shaped like an upturned umbrella. The jacaranda tree makes an excellent shade (or street) tree with its fern-like leaves that can grow up to 20 inches in length. It is a fast-growing tree in a tropical environment, gaining about ten feet a year in its first years of life. Its growth rate varies depending on where it's grown, slowing down to a moderate growth rate outside its ideal tropical environment.

Typically planted between fall and early spring, the jacaranda tree can be considered semi-evergreen or deciduous, depending on where it lives. Only mature jacaranda— eight years or older—will flower, blooming in late spring to early summer (though in warmer areas, the tree can flower at any time). Native to South America, it is an invasive species in several parts of the world.

Jacaranda Tree Care

In general, jacaranda trees are a good choice for large outdoor areas in warm climates, USDA hardiness zones 10 and 11. They are resistant to pests and diseases and are moderately drought-tolerant (though they require watering during extended dry periods).

The fern-like foliage usually allows diffuse light to pass through, so growing grass under the tree is possible. But, be aware that the tree can have significant surface roots, disturbing sidewalks or nearby structures. Jacaranda leaves, and particularly the flowers, can create a lot of litter when they drop. This messy habit makes the tree a poor choice near pools, driveways, and patios because of cleanup maintenance. If the debris isn't swept up quickly, it can rot and result in a slimy, slippery mess.

Though jacaranda trees can be grown indoors, they typically will not flower. They must be planted outdoors eventually and are not good for long-term container planting. When grown indoors, jacarandas can attract aphids and whiteflies. 


The jacaranda tree has an invasive growth habit in the tropical zones of Hawaii, Queensland, Australia, Chile’s Juan Fernandez Islands, Kenya, Tanzania, South Africa, and Zambia. It is deep-rooted, competes with other plant life, and few plants can grow beneath it. It can form thickets of seedlings and decrease biodiversity in an area.

For the best blooming, plant your jacaranda tree in full sun, where it receives at least six to eight hours of sun per day. Smaller jacaranda trees can tolerate light shade if necessary, but a lack of optimal sunlight can impact the amount and vibrancy of their blooms.


Jacaranda trees will do best in well-draining, moderately sandy soil with a slightly acidic pH level. It's also tolerant of clay and loamy soils but should not be planted in any mixture that is considered heavy, wet, or not well-draining. Water-logged soil can lead to an increased risk of root rot and mushroom root rot.


As a general rule, water your jacaranda tree when the top three to four inches of soil feels dry to the touch. These trees need consistent moisture throughout the year and often require additional watering during high heat or drought periods. Water the area around the tree's base. Concentrate most of the water at its drip line (the spot where the water drips off the ends of the branches) instead of near the trunk.

To gauge whether your watering was sufficient, poke a finger or water gauge into the ground up to three inches deep, ensuring the water has seeped down to that depth. Repeat watering this way once a week, increase to several times a week during intense sun or heat periods. Reduce watering to once a month during the tree's dormant winter months.

Temperature and Humidity

Some jacaranda trees can tolerate occasional cold weather days (as low as 20 degrees Fahrenheit), but generally, this species does not thrive in climates with frequent freezing temperatures. This plant prefers heat and humidity but is vulnerable to trunk scald in areas with constant high temperatures.


Feed your jacaranda tree annually with a balanced tree fertilizer, but be careful not to give it too much nitrogen, which can affect flowering. A good fertilizer ratio is 10-10-10 NPK (nitrogen-phosphorus-potassium). If you are fertilizing grass under the tree, chances are the tree is already getting a lot of nitrogen.

Types of Jacaranda Tree

There are several notable varieties of jacaranda mimosifolia:

  • J. mimosifolia 'Alba' or 'White Christmas': Full-size tree with a similar habit and care needs; grows up to 40 feet tall and 60 feet wide; lush foliage; its white blooms might arrive earlier than other varieties, starting in April in some climates
  • J. mimosifolia 'Bonsai Blue': Dwarf cultivar with deep purple blooms; matures at only 10 to 12 feet tall and six to eight feet wide; grows in USDA hardiness zones 9 through 11
  • Jacaranda jasminoides: Dwarf cultivar that grows 10 to 25 feet tall produces lilac to dark purple tubular flowers
  • Jacaranda jasminoides ‘Maroon’: Dwarf variety that grows 10 to 25 feet tall with dark maroon-purple blooms

You should prune young jacaranda trees to form one central leader (main trunk) for strength and stability. Avoid pruning beyond that; too much pruning might force it to grow vertical suckers that can distort the tree's shape. Seasonal pruning should be limited to removing only broken, dead, or diseased branches.

Propagating Jacaranda Trees

It's best to plant the seeds of this tree between fall and early spring. You can also propagate this plant from a stem or branch cutting (softwood). Grafting is another method, but it's best done by nursery or horticultural professionals. Propagating via softwood cutting is more advantageous because your plant will bloom much sooner than a plant grown from seed. Also, stem cutting is the more reliable method of propagation because the child plant will be a true copy of the parent. Here's how to propagate by stem cutting:

  1. Use pruning shears or hand pruners to trim off a 1/2-inch to one-inch diameter branch. You'll also need either a clear jar of water or a pot of moistened soilless potting mix (with perlite), or a sandy, loamy mix. If you use the water rooting method, you will eventually need a pot of potting soil to plant the rooted stem.
  2. Take a cutting from a branch that has grown past the bark and contains healthy buds. Cut it just above a node (the point where the leaf grows from the stem). Make at least a one-inch diagonal cut; the longer cut surface encourages rooting. The cutting should be at a minimum of three to four inches long and should have at least three nodes on it.
  3. You can put the cutting in a clear glass or jar of room temperature filtered water until roots form (about two weeks), then plant it into potting soil. While you wait for the roots to grow in the water, replenish the water level with filtered, room temperature water. Or, you can directly plant the cut end in an enriched, moist soilless growing medium. Optionally, you can dip the cut end into rooting hormone to boost its chances of root production.
  4. Place the plant in a bright location but not direct sunlight; direct sunlight can burn or dehydrate the cutting.
  5. Once the water-rooted cutting has roots at least one inch long, replant the cutting into a soilless potting mix. After that, do not transplant the cuttings for at least eight months. Allow the plant ample time to establish its root system. Then, find a more permanent home for the plant outdoors or transfer to a larger pot—at least five gallons or more.

How to Grow Jacaranda From Seed

The fruit of the jacaranda tree is a dry round brown pod that is one to three inches wide and typically develops in late summer. To harvest the seeds for replanting, pick the seed pods directly from the tree when they are dry (pods that have fallen to the ground might not contain seeds).

  1. Soak the seeds in water for 24 hours.
  2. Place the seeds on a bed of potting soil in seedling containers or pots. Cover them with a thin layer of potting soil and keep the soil moist. The seeds should sprout in two to eight weeks.
  3. Wait eight months before you transplant the seedlings.

Potting and Repotting Jacaranda Trees

Container-grown jacaranda trees will need to be planted in containers at least five-gallons in size, using a sandy loam potting mix that drains quickly. The soil should be kept moist but not soggy throughout the active growing season.

If you are transplanting jacaranda, do it in the winter after they drop their leaves but before they bud out in early spring. Transplanting them while they are dormant reduces stress and increases the likelihood of success.

In the tropics, these trees grow 50 feet tall, outgrowing containers. But in cooler climates, they can be grown as container trees growing to about eight to ten feet if you annually prune and shape the tree during dormancy to keep it on the smaller side.


As tropical trees, these plants will likely not survive climates that freeze for extended periods. It can handle a cold snap here and there, but beyond that, you're asking for tree death. If your winter temperatures sometimes dip, the tree can tolerate occasional 20 degrees Fahrenheit days with a cold snap here or there. To mitigate any potential winter frosty days, think ahead and plant the jacaranda in a sunny area that has some protection from gusty winds.

When jacaranda trees in pots are taken indoors for the winter, they should be watered less frequently and allowed to dry out a bit. A dry period in the winter triggers more blooms in the spring. Similarly, a soggy, wet winter usually means the tree will produce fewer blooms in spring. Prune the potted plant during the dormant winter period; this keeps your potted jacaranda tree from growing too large. Each year, it becomes more difficult to bring the plant indoors for the winter if you don't prune it.

Common Plant and Pest Diseases

The jacaranda tree is susceptible to aphids and scale insects, and the glassy-winged sharpshooter can also infest its leaves. You can manage all of these pests with insecticidal soap or horticultural oil.

Disease rarely affects jacaranda trees; however, insects like the sharpshooter carrying the bacteria Xylella fastidiosa can cause trees to develop bacterial leaf scorch. The bacteria block the tree from getting the water it needs. To prolong the tree's life, water it frequently. However, there is no cure for the disease, so ultimately, the tree will not likely survive.

Trees that do not have properly draining soil can develop mushroom root rot. This disease is caused by a pervasive fungus and has no real cure other than removing the dying plant. To confirm this disease, it appears like an area of the bark has blackened and died. Upon peeling back the dead bark, you'll notice a white fungal growth.

How to Get Jacaranda Tree to Bloom

Jacaranda trees bloom twice a year, once in spring in late May or early June, and again in the fall. The trumpet-like blooms have a freshly fragrant smell, although their decomposition is pungent and foul-smelling when the flowers wither and fall. This tree is on the messier side; sweep and rake the spent blooms as soon as you can to avoid a smelly situation.

For the best result with getting a jacaranda to bloom, plant it in a sunny area with well-draining soil (preferably sandy). Make sure the ground around a jacaranda tree remains moist but not soggy. Protect the tree from harsh winds. Stop fertilizing grass growing nearby a jacaranda. Fertilizer, particularly nitrogen, inhibits flower production.

Common Problems With Jacaranda Trees

In the U.S., these trees are happiest in the balmiest locations—Hawaii, the South, Southern California, and parts of Texas. They grow remarkably easier there, where the conditions are ideal. Problems crop up most when its water, sunlight, and temperature needs are not being met.

Yellowing Leaves

If your tree is not watered deeply enough, it might not produce enough chlorophyll, causing chlorosis, which causes green leaves to turn yellow. Provide your tree with ample water. Water on a schedule and give your plant a deep watering on overly hot days.

Browning, Dying Leaves

Trees that have developed the insect-borne bacterial leaf scorch disease look like they are deprived of water. Leaves begin wilting, browning, and dropping. The branches and stems dry out and become brittle. There is no cure for this disease. Other potential causes for browning leaves are leaf scorch from too much sun or an overabundance of fertilizer. Check those factors. If the sun is overwhelming for the plant, it might be worth it for you to transplant the tree to a more suitable location.

Dead Leaf Tips

Excessive fertilizing can damage the mineral to salt ratio in the soil, causing dead leaf tips and yellowing leaf edges. If the leaf tips appear to die after fertilizing, it might be the cause of your tree's leaf issues. To correct an overfertilized tree, remove the dying or wilting leaves and water the fertilized soil thoroughly, trying to flush out the fertilizer.

A view from an airplane over a city with lots of jacaranda trees in bloom is no less than stunning. As you look down on the forest of green, billowing lavender blue-violet flowers grace the jacaranda canopies in the spring. Jacaranda grows 25 to 40 feet tall and 45 to 60 feet wide when mature, but only in U.S. Department of Agriculture Plant Hardiness Zone 9b and warmer. Used as a street or park tree in Southern California, Hawaii and the southern half of Florida, jacaranda grows best with minimal but precise pruning maintenance.

Pruning Season

Schedule pruning of jacaranda trees for mid- to late winter, when the tree is dormant without many leaves. In parts of the U.S. where jacarandas grow, pruning time may occur anytime from late January to the end of February. Warm, wet winters prevent leaves from dropping away and can diminish the flowering display later in the spring. Jacaranda trees are weak-wooded and thin-barked. Any pruning done needs to be light and minimal. Otherwise, many suckering watersprout shoots can develop from the pruning wounds, especially during the spring and summer.

What to Prune

Focus pruning maintenance on a jacaranda to remove dead or diseased wood, or to improve its structural integrity. Dead wood may be removed at any time of year, but if trees are tall, it's best to use an arborist who can also address any structural issues in the late winter. Remove any vertical suckering sprouts in the canopy. Avoid over-trimming, as more wounds lead to more suckers from pruning wounds, especially on large branches or the trunk.

Structural Insight

When considering a jacaranda tree to plant, only purchase saplings with one main central trunk. Avoid specimens with lots of narrow forks and tightly spaced branches. These trees will require a good deal of pruning to improve their strength and long-term integrity, especially in a wind-prone region. A single-trunked jacaranda will develop a stronger habit, especially if poorly positioned branches are removed when it's young. Even with proper pruning and annual maintenance, expect a jacaranda tree to sustain damage in strong tropical storms.

  • A single-trunked jacaranda will develop a stronger habit, especially if poorly positioned branches are removed when it's young.

Follow-up Pruning

Creating any pruning wound on the jacaranda, regardless of the tree's age or size, always leads to unsightly vertical suckers. Minimal pruning on well-structured trees diminishes suckering, but follow-up pruning every four to eight weeks in the summer is needed to remove suckers. In small trees, cutting off suckers before they get large and ruin the branching silhouette of the jacaranda may be done on a ladder with hand pruners, or an extension pole. Large trees may need suckers removed every late winter when the arborist conducts his annual structural evaluation.

growing tips: care, planting and transplanting, fertilizers and soil Peter Pete, watering, pruning, diseases and pests

Jacaranda (fern tree, rosewood tree, violet tree) - perennial evergreen plant of the family Bignoniaceae from India and South America. This still rare guest in our area in her homeland reaches a height of 20-30 m. But, as you know, the true love of a gardener knows no barriers, and an outlandish fern tree, breathtakingly blooming in the spring with huge violet, pink, lilac, bicolor clusters , was turned into a pretty bonsai that fits perfectly into literally any interiors. And although the jacaranda is very capricious and requires increased attention, believe me: it is really exotic, and how pretty it depends on your hardworking hands ...

Recommended species

Pointy-leaved jacaranda, Mimosole jacaranda.

Growing conditions

Location. Jacaranda during the period of activity prefers bright diffused light, so the eastern, western and southern window sills will be the best places for its habitat at home. On the southern windows, you will have to provide diffused light with the help of tulle, blinds, etc. Jacaranda is thermophilic, does not tolerate drafts and temperature changes. It is necessary to maintain a uniform temperature: in summer + 23-25°C, in winter + 18°C. Relative humidity of the room - 65%.

Soil. The soil for jacaranda should be loose and nutritious: mix your own soil with sod, leaf soil, peat and sand (1:2:1:0.5) or simply use the ready-made soil PETER PEAT "For flower crops" of the HOBBY line.

Pot. Before planting, pour lukewarm water over the jacaranda pot, carefully remove it with a clod of earth. At the bottom of a wide and shallow pot with drainage holes, transplant the plant, fill the voids with fresh soil, compact the soil, pour with a solution of liquid humic fertilizer PETERP PEAT "Living Force: Universal". After planting, the root neck of the tree should remain above the ground.


Watering. In the spring-summer period, water jacaranda abundantly, 3-4 times a week, the rest of the time - as the topsoil dries, with soft, settled or filtered water. During this period, provide high humidity around the jacaranda. Moisten the tree itself and the air around it with frequent spraying, or place the pot on a tray with wet pebbles / expanded clay (so that the bottom of the pot does not touch the water).

Top dressing. From May to October, alternate between PETER PEAT Liquid Humic Fertilizer "Living Force: Universal" and PETER PEAT Liquid Complex Mineral Fertilizer "Mineral Balance: For Flower Crops" once every two weeks. During periods when the tree sheds leaves, it is not necessary to feed.

Cutting. Formation of the jacaranda crown by pruning is best done in mid-late March . Some growers deliberately bend the branches and shoots of the plant using wire and small weights. The splendor of the crown is facilitated by regular pinching of its growth points.

Rest period. From November to March, the jacaranda goes into hibernation: place it in a room with a temperature of + 18 ° C, do not feed, water once every 10 days as the top layer of soil dries out.


In mid-March, young jacarandas are transplanted annually into a new pot (+15% of the old volume) with new soil. An adult jacaranda can be transplanted into a new container by transshipment with the replacement of the top 4 cm layer of soil if the plant is older than 3 years. Remove the jacaranda from the pot along with the earthy clod, transfer to a new pot. At the bottom of the pot, provide a drainage layer sprinkled on top with a thin layer of substrate. Then add soil a little at a time and compact it. The root neck should remain above the soil surface.


Cuttings. In June-July, cut the top cuttings 10-12 cm long from the adult jacaranda, remove the leaves from their lower halves and immerse them in liquid humic fertilizer PETER PEAT "Living Force: For Soaking Seeds" for 10-12 hours. Then deepen them 3-4 cm into moist soil, cover with a transparent film and place the container with the cuttings in a room with a temperature of + 24-26 ° C and a phytolamp (at least 8 hours / day). Ventilate 4-5 times a day, removing the film and removing condensation from it. After 17-20 days, the cuttings will take root - new leaves will testify to this, and you can dive them into new pots for permanent residence.

Seeds. In the middle of March, wrap the jacaranda seeds in 2-3 layers in gauze. Put gauze in a saucer with a solution of liquid humic fertilizer PETER PEAT "Live force: for soaking seeds" for 10-12 hours. Then dig them into the ground by 1 cm in 4 cm increments, cover with a transparent film and place the seed container in a room with a temperature of + 24-26 ° C and a phytolamp (at least 8 hours / day). Ventilate 4-5 times a day, removing the film and removing condensation from it. After 22-25 days, the seeds will germinate and they can be dived into separate pots.


  • Falling leaves in spring is a natural process, as it should be.
  • Leaves turn yellow lack of iron.
  • The plant does not bloom - not enough light or nutrition in the soil, wrong mode during the dormant period, excess nitrogen fertilizers.
  • Leaves are curling - too much fertilizer.
  • Root rot - overflow and/or poor drainage.


  • Spider mite - the smallest animal that feeds on plant sap, leaving behind dry patches covered with thin cobwebs. Lays up to 150 larvae-eggs on the back of the leaves. As a result, the plant becomes ill, slows down in development and dries up. How to fight: keep the required landing distance; loosen and disinfect the soil more often; use insecticides - Apollo, Aktellik, Karbofos.
  • Whitefly (aleurodida) - the smallest, up to 5 mm, yellowish insect with a wax coating on the wings, feeds on plant sap and produces secretions that promote the appearance of fungus on the leaves. The leaves become covered with a sticky crust and gradually die off. How to deal: regularly inspect the plant for disease and prophylactically treat it with soapy water once every 10 days; if time is lost, use insecticides - Akarin, Fitoverm, Vertimek.
  • Scale insect - brownish insect 2-4 mm with a hard shell, feeding on juices of leaves and stems. In this case, the plant is covered with sticky brownish spots. How to fight: collect all the insects with a toothbrush in a glass and treat the plant with insecticides Admiral, Golden Spark, Karbofos.

Good luck!

The jacaranda in the room is an exotic dream tree. Care at home. Photo — Botanichka

Jacaranda bloom is one of the unforgettable impressions. Luxurious trees turn into a violet cloud in a warm climate, remaining with us a plant of an unattainable dream. Almost unattainable, because in the list of elite indoor plants that you can buy for yourself, there is also an exotic jacaranda. It is grown for the longest time as a bonsai, because in its natural size in a room it can not live for many years. Not everyone can afford to support comfortable jacaranda conditions and care. But if you decide to buy, it is better to pay attention to even the smallest things and get ready for the fact that the flowering of jacaranda on the windowsill will remain an unattainable dream.

Jacaranda in the room - an exotic dream tree

Violet tree in a not quite mini size

Representing the Bignonian family, the jacaranda is one of the most valuable and spectacular flowering trees on our planet. It is no coincidence that her beauty is compared either with beavers, or with wisteria, or with paulownia.

Nobody managed to tame this plant to the end and make it truly domestic. Jacaranda is often planted as an exotic dream, admiring only the leaves or bought as one of the most expensive types of bonsai, which is easier to destroy than to save. They are trying to "domesticate" only one of fifty species of jacaranda - Jacaranda mimosifolia ( Jacaranda mimosifolia ).

Jacarandas , blue jacarandas , rosewood trees , violet trees or fern trees are evergreen, large or medium-sized trees from tropical and subtropical regions of Latin America. Domestic jacarandas grow to that measure of the natural 20-30 m, to which the space of the room and the ceiling will allow them. Most often, jacarandas are grown up to 1-1.5 m in height, which, with a fairly rapid growth, takes only a couple of years. Thin, winding, often almost zigzag, graceful shoots with a smooth grayish bark are intricately curved. With age, very spectacular silhouettes are formed.

Jacaranda leaves are irresistible even in very young plants. The extraordinary beauty of delicate, double-pinnate, somewhat reminiscent of fern fronds of large leaves conquers with bright shades of greenery, and delicate texture, and patterns. Length up to 45 cm further enhances the resemblance to ferns. With age, the trunk becomes more and more exposed, the lower leaves gradually fall off.

The name of the jacaranda "fragrant" alludes to the fragrant bloom. But neither the smell nor the beauty of the inflorescences in the rooms can be enjoyed. If potted jacarandas bloom, then only in ideal conditions, in the form of bonsai and at a very respectable age. Apical brushes with all shades of blue and lilac consist of fragrant, with a fancifully curving tube and a five-petal corolla of flowers with a special long staminode. In nature, flowers turn jacarandas into a blue-purple haze.

The bizarre woody seed pods with elongated pods remain only a dream in indoor format.

Growing Conditions for Indoor Jacaranda

Since it is almost impossible to get flowering from jacaranda, it is more appropriate to think of it as an ornamental leafy plant and approach cultivation accordingly. After all, all efforts to organize a period of rest are still unlikely to pay off. But even so, you need to find the right place for it.

Lighting and placement

Jacaranda likes a bright but not sunny place and long daylight hours. Soft morning or evening sun (at least 3-4 hours) is suitable for her, it is better to protect the plant from the daytime with a diffusing screen. The ideal place can be safely considered the western window sills.

Lighting should be increased as much as possible in winter. Ideally, you need to illuminate the jacaranda, stretching the daylight hours up to 12-13 hours. The intensity of lighting in the cold season should correspond to the southern window sills. Only the brightest and most stable lighting all year round allows older plants to bloom.

The jacaranda should be rotated regularly in relation to the light source for even development.

Read about jacaranda also in article 8 whimsical indoor plants worth growing for beginners.

Temperature and ventilation

Jacaranda may love the high humidity of the tropics, but it does not tolerate the heat in a potted format. It is best grown in moderate temperatures, in summer - from 21 to 25 degrees.

Winter mode - with a temperature of about 16 degrees. The minimum indicators that the jacaranda can withstand are 12 degrees Celsius, but indoor plants most often suffer already at 15 degrees. If it is possible to compensate for changes in lighting and constantly keep the jacaranda in high humidity, a warm winter is also acceptable.

Jacarandas do not tolerate drafts, they can only be taken out into the fresh air for a few days (when the temperature at night is above 16 degrees).

Caring for jacaranda at home

Pay attention to everything. Jacaranda is quite demanding and is more suitable for experienced flower growers.

Irrigation and air humidity

Jacaranda does not like waterlogging, it tolerates drought even worse: when the soil is completely dry, the plant sheds its leaves. It is better to water the jacaranda so that the water does not stagnate in the pan, and the substrate dries up 1-2 cm from above. Frequent watering with soil monitoring is preferred. For the winter, watering is reduced by about half. Jacarandas can be watered only with soft and tepid water. Jacaranda loves stable humidity, so mulching the topsoil is only welcome.

Jacaranda requires air humidity from 70%. The plant can be sprayed as often as you can. Do not interfere with the installation of humidifiers.

Top dressings and fertilizer composition

Fast growing jacarandas react very strongly to top dressings. Therefore, a strategy of minimal use of fertilizers is used for them. In the first year after transplanting, top dressing can only be applied a few times during the summer, but the standard strategy is usually used with the first top dressing not earlier than 6-7 weeks after soil change and at intervals of 1 every 3-4 weeks, only in spring and summer.

For jacaranda, it is better to choose organic-mineral universal fertilizers or alternate mineral and organic top dressings.

Pruning and shaping the jacaranda

It will not be possible to fully restrain the jacaranda, it still grows quickly and turns into a giant before our eyes. But in order to slightly extend its stay in the interior until it reaches its maximum size, you can pinch the shoots and carry out partial pruning, which does not always give the desired result.

For bonsai, the plant is formed from the second year, after pinching the top and the beginning of the growth of lateral shoots, a soft thick wire is used to guide the shoots and tweezing. The branches are not very strong, they break easily, loads and wire must be attached and wound very carefully.

Transplanting, containers and substrate

Don't change containers even for young jacarandas before roots appear in the drainage holes. The plant is carefully rolled over in the spring. In years without transplantation, the topsoil is changed twice a year.

Classic, tall, stable pots and natural materials are preferred. For bonsai choose wide bowls. The volume is increased by no more than 3 cm, tight pots hold back growth a little.

A high layer of drainage is laid on the bottom. When transplanting jacaranda, it is better not to destroy the earthen lump, and leave the root neck above the soil level, adjusting the depth with a mulch layer. If the root collar is covered with soil or mulch, the plant will stop growing. After planting, the plant must be kept in soft lighting and temperatures with high humidity.

Jacaranda grows best in nutritious, loose soil mixtures based on leafy soil with the obligatory addition of baking powder in addition to coarse sand. Excellent substrates for tub plants.
