Jacaranda Mimosifolia Plant Care

Table of Contents

Did you know that the Jacaranda mimosifolia is grown because of its lovely blossoms? It’s because the flowers that have fallen to the ground create a stunning blue carpet!

The tree’s extended blooming season might even last up to a month. However, the blooms don’t have much of a scent to them. Did you also know that in sections of South Africa and Queensland, Australia.

Jacaranda mimosifolia is considered an invasive species? It is because it can outcompete native species. It can develop dense seedling thickets beneath planted trees, allowing the species to spread and obliterate surrounding plants. However, some still love to cultivate this beauty. And we cannot blame them.

If you want to grow Jacaranda trees, you’ll need to consider having a lot of areas for them to thrive. It’s because mature trees may reach a height and width of at least 10-15m in ideal conditions. So they’re probably not the best choice for a tiny backyard or as a fence-side planting – your neighbors might not be impressed. This, if you treat them as an outdoor plant as we mostly love them to be indoors.

Now, if you have that requirement, you’re ready to have your Jacaranda. But wait? You don’t know how to cultivate them? Then, don’t worry, Plantly got your back. Read below to find out more!

Recommended Potting Mix

The optimal soil for Jacaranda trees is well-draining and somewhat sandy soil with a slightly acidic pH. That said, it should not be planted in any heavy, moist, or poorly draining soil composition. It’s because root rot and mushroom root rot are more likely to occur in waterlogged soil. In terms of pH, it can survive and thrive in a wide range of values between 5.5 and 8.

It does, however, prefer slightly acidic to neutral reaction soils with pH values ranging from 6.5 to 7.

Pro tip: They should also not be cultivated near water, as the salty sea wash damages their leaves.

Watering Needs

These trees necessitate continuous moisture throughout the year. They frequently require extra watering during periods of extreme heat and/or dryness. Never let the soil where the Jacaranda tree is planted grow completely dry.

If your tree experiences water stress, the chlorophyll level in the leaves will decrease which subsequently results in decreased photosynthetic rate. If possible, don’t allow this beauty to suffering from such.

Lighting

jacaranda lighting requirement

Plant your Jacaranda tree under full sun, where it can get at least six to eight hours of rays per day for the best blossoming. The Blue Jacaranda Tree, on the other hand, can endure light shadow. Keep in mind that while a Jacaranda can grow in partial shade, it will grow faster and flower more lavishly in full sun! Smaller Jacaranda trees can survive in light shade if necessary.

Still, the volume and brilliance of their blossoms may be harmed.

Recommended Temperature & Humidity

Jacaranda trees thrive in USDA zones with temperatures far over 27 degrees Fahrenheit. Although certain Jacaranda trees can tolerate cold temperatures as low as 20 degrees Fahrenheit (-6.6 degrees Celsius), they do not survive in locations with frequent freezing temperatures.

They prefer a lot of heat and humidity. However, they are susceptible to trunk scald in locations where the temperature is consistently high. The optimal humidity level is between 40% and 60%, which is frequently challenging to obtain.

If this ideal condition is not met, tropical plants may turn a pale green tint, and their lower leaves may turn yellow and drop. So you can place a humidifier if they have grown an indoor plant in the form of bonsai. Or, you can even group plants together to achieve the proper moisture.

Fertilizer Requirement

plant fertilizer

The fertilization of Blue Jacaranda trees takes place from the beginning of spring until the beginning of summer. For Blue Jacarandas to thrive, a yearly dose of 10-10-10 fertilizer will suffice. For each square foot of soil beneath the tree, one tablespoon of fertilizer should be given.

Propagation

One of the most typical ways to propagate Blue Jacaranda is to sow seeds. It is done primarily in the spring, around March. The Jacaranda tree’s fruit is a dry circular brown pod that grows one to three inches wide and appears in late summer.

Here’s how you will do it:

  • Harvest the seeds for replanting by picking the pods directly from the tree when they are dry. Some pods may not contain seeds, so look for them patiently.
  • Immerse the seeds in water for 24 hours before planting them in seedling containers or pots on the soil bed.
  • Keep the soil moist and cover them with a thin layer of dirt.
  • In about two weeks, the seeds should sprout. After around eight months of growth, you can transplant the seedlings.

Growth Zone

Jacarandas grow best in USDA plant hardiness zones 9 to 11. However, they can survive in any climate without the cold. When the temperature dips below 15 degrees F, the toughness of the jacaranda tree is put to the test.

Potting

Jacaranda trees (Jacaranda mimosifolia) are tall blooming trees that cannot mature in a balcony garden plant pot. This tree, like many others, can be cultivated young on a balcony garden (or even indoors if you have a sunny spot).

Every Jacaranda planted in a pot (a 5-gallon or larger) will eventually need to be transferred into the ground. Therefore you may have to give up your Jacaranda at some point (unless you buy a house with a nice big yard).

Pruning

Rapid growth may appear to benefit, but the resulting branches contain delicate, easily damaged wood. The canopy of a jacaranda tree can be thinned by pruning it. Branches that grow at less than a 40-degree angle to the stem should be removed.

These branches are prone to break on a windy day because they aren’t securely tied to the tree. Cut branches back to the collar where they attach to the trunk to remove them. Never, ever, ever leave a stub.

Branches that are dead or broken should be pruned as they appear throughout the year. Broken limbs should be pruned back to just beyond a side stem. Winter is the optimum time to prune jacaranda trees before new growth begins.

Jacaranda Mimosifolia Varieties and Other Similar Plants

If you’re looking for other plants just like this beauty, Plantly also gives you that! I know you will surely love them and want to cultivate them also! Here are some of the Jacaranda mimosifolia’s varieties and similar plants:

Vitex Tree

vitex tree

The Vitex tree or Chaste trees are shrubs or small trees that reach a height of 15 to 20 feet (5-6 meters) with a spread of 10 to 15 feet (3-5 m.). It attracts butterflies and bees, and it’s an excellent source of honey. Vitex blooms with tall, upright spikes of pink, lilac, and white flowers from late spring to early October.

J. mimosifolia ‘Bonsai Blue’

The world’s first dwarf Jacaranda, Jacaranda Bonsai Blue, is very extraordinary. This little tree grows 30 inches tall and wide, with fern-like foliage and lovely purple-blue blossoms. The Jacaranda Bonsai Blue is an excellent tree for compact gardens, as a single plant on your patio or in mixed containers.

J. mimosifolia’ Alba

Tubular blue or lavender-blue blooms with white throats, 2 inches long, emerge in several 8-inch-long clusters. With a rounded, spreading appearance, it quickly expands to 4560 feet tall and 2540 feet wide. ‘Alba,’ a white-flowered variety with lusher foliage and sparser blossoms, is occasionally available.

Jacaranda Mimosifolia Diseases & Pests

The majority of challenges with Jacaranda trees are minor, ranging from a few bug issues to cultural issues.

Pests

Bean aphids (Aphis fabae) can be a year-round pest in mild winter areas where jacarandas grow. Stacks of the black insects cover the stems and backs of the leaves in great numbers, draining sap and giving birth to as many as five live young per day.

Jacaranda leaf fluids are also drained by glassy-winged sharpshooters. The fluid waste they produce dries on the branches and other surfaces, forming a white coating. The 1/2-inch transparent-winged bugs not only make a mess, but they also spread the deadly Xylella fastidiosa bacteria.

These pests are controlled by organic insecticidal soap, although total control on huge jacarandas takes time. Treat the tree on a gloomy day when the temperature is projected to stay below 90 degrees Fahrenheit.

Diseases

The disease rarely affects this Jacaranda tree. However, bacterial leaf scorch might be an issue if the correct insect vectors are present. More than 100 species of trees and shrubs are affected by different Xylella fastidiosa, the bacteria that causes the illness.

Bacterial leaf scorch affects the water-conducting tissue in plants and shrubs. As a result, the signs and symptoms resemble those of drought or heat stress.

Bacterial leaf scorch has no treatment. You may extend the life of the tree by keeping the soil surrounding it moist. However, as long as the tree exists, it serves as an inoculation source for disease-transmitting insects.

Frequently Asked Questions

How long does it take for a jacaranda tree to bloom?

There are many factors that this beauty may not give you its blossoms. These factors may be:

  • Age – Grafted trees produce their first blooms earlier in the range, but trees developed from seed can take much longer. If your tree is younger than this, you may only need to be patient.
  • Soil fertility – When it comes to Jacaranda flower difficulties, too much nitrogen may be to blame.
  • Sun and temperature – If Jacarandas get less than six hours of sunlight per day, they won’t flower well.
  • Moisture – During droughts, Jacarandas produce more blossoms. Make sure your Jacaranda doesn’t become too wet.
  • Wind – Some gardeners assume that a Jacaranda’s blossoming will be harmed by salty seaside breezes.

How to revive my Jacaranda miosifolia?

When the Jacaranda is overwatered, the leaves become yellow, wilt, and drop prematurely. Overwatered plants are more likely to have smaller leaves, branch tip die-off, and premature leaf drop than healthy plants. Overwatering leaches minerals from the soil, which could be a contributing factor in a sick tree.

How long does it take for Jacaranda miosifolia from dying?

A Jacaranda tree has a 50-year average lifespan. They can certainly live for far more extended periods, with some living to be over 200 years old. They mature in around 20 years and can re-grow if they are destroyed by fresh dropping seeds.
