Rosewood trees are a very special exotic beauty. In their native South America, the Jacaranda trees with their blooms transform entire streets into a blue-violet sea of flowers. The rosewood tree has also become at home in other climatically favorable regions of the world. If you want to surround yourself with this exotic splendor, you unfortunately have to limit yourself to the bucket position. In summer, the plants can decorate the balcony or terrace. They spend the winter indoors. In order for the rosewood trees to thrive, it is important not to make any mistakes when planting. You can read up on what needs to be considered here.
The rosewood tree belongs to the trumpet tree family. In the great outdoors, the plants reach heights of up to 20 meters. The jacaranda tree is characterized by a thin brownish bark and a more rounded tree top. The filigree pinnate leaves can be up to 40 centimeters long. The leaves are opposite. Stipules are not available. The blue-purple panicle flowers are the real ornament. The flowers, which are up to five centimeters long, appear in November and decorate the rosewood tree for up to eight weeks.
Spread of the rosewood trees
When it comes to planting in our latitudes, the natural range of the respective plant always plays a role. The home of the rosewood tree is in southern America. There the trees grow mainly in Bolivia, Argentina or Paraguay. In the meantime, due to their attractive bloom, the crops are cultivated in almost all subtropical climates worldwide. The Jacaranda trees can also be discovered in Australia or on a trip to the Canary Islands. The cold-sensitive plants are not suitable for free-range in Germany.
Annotation: The rosewood tree can withstand brief frost breaks in the single-digit range.
Plant a rosewood tree - find your location
It would not be advisable to think about keeping the rosewood tree outdoors. Even in mild regions of Germany, the plants would not survive the winter. While brief cold spells are coped with fairly well, constant temperatures in the single-digit range mean the end of the plant for a longer period of time.
Rosewood trees need a bright and sunny location. Full sun exposure is less well tolerated. South-facing window fronts are therefore less suitable. However, an east or west window is recommended. In summer, the plants feel comfortable on the balcony or terrace. The trees like high humidity. Here the hobby gardener can help with increased spraying.
The jacaranda trees require a lot of space, both in the bucket and in the room. If you let your rosewood tree grow tall, you will enjoy an attractive, branched growth and, with a little luck, you may even be able to marvel at the unmistakable flowering of the plants in our latitudes. When standing on the balcony or terrace in the summer, make sure that the plants do not tip over. Stable terracotta planters counteract this.
The ideal location in brief:
- high humidity
Select the right substrate
The rosewood tree thrives best in a lime-free substrate. The value of the soil can be improved by adding compost or horn chips. This gives the plants a high-quality natural fertilizer when they are planted. If you want to use the finished substrate, azalea is a good choice. To make the soil permeable and to prevent waterlogging, lava granules or expanded clay can be added to the soil.

The ideal planter for the rosewood tree
With the appropriate planter you create the basis for healthy growth of your jacaranda tree. So that the roots can develop well, the planter should be of sufficient size. The height is particularly important. The right planter is about a third higher than it is wide. Take a look at your planter from below. Sufficient water drainage holes ensure that the irrigation water can drain off easily and that there is no waterlogging.
Also keep in mind that sooner or later the rosewood tree will have to be repotted. The best way to do this is to use a conical planter. If the plants are well rooted and spread in the planter, removal from bulbous planters is usually problematic and if you do not want to injure the plant, you have to destroy the planter.
An overview of plant preparation
|What should I do?||explanation|
|Find location||Where the rosewood tree is placed depends on the time of planting.|
The plants can spend the summer in a bright and sunny place on the balcony or terrace.
In winter about 15 degrees are needed.
Pleasant midday sun tolerates the plants less.
A high level of air humidity accommodates the rosewood tree.
|Select substrate||Rosewood trees love nutrient-rich soils.|
Therefore compost can already be mixed in during planting.
The floor should be loose and permeable.
The plants don't like lime.
Azalea is very suitable.
|Provide planters||Sufficiently large planters offer ideal growing conditions.|
So that the roots can spread well, the height of the planter is particularly relevant.
This should exceed the width of the vessel by a third.
Conical planters make transplanting easier.
Planting rosewood trees - step by step
- Select planter
- Water clay planters beforehand
- Also water the plant
- Place drainage in the planter
- Fill the substrate into the bottom of the container
- Press on the substrate
- Place the plant in the center of the tub
- Fill in the substrate
- pour on carefully
If your planter is made of clay, you should water it for about two hours before planting. This allows the clay to soak up water and does not extract moisture from the soil after planting. The roots of the rosewood tree are also placed in a bucket of water.
Ensure good soil permeability by creating a drainage made of gravel or pottery shards. This should be covered with a permeable material. Now you can fill in the first layer of substrate and press it down well.
The plant is carefully placed in the center of the planter. Now you can gradually fill up the substrate.
Attention: The earth must be pressed on well. Otherwise voids are formed which the rosewood tree cannot root through. This leads to a weakening of the plant.
Do not press the substrate too hard to allow the roots to penetrate the earth. There should be a few centimeters of clearance between the edge of the planter and the layer of soil.
After planting, water well. If the earth should sink, add some more substrate.
A mulch layer is advantageous at the summer location. This ensures permanent soil moisture and prevents weed growth and egg laying by insects.
When should the rosewood tree be repotted?
Since the plants are rather fast-growing, repotting is advisable for young plants. You can see whether you have to repot when looking at the plant pot. At the latest when the root network already appears clearly visible, it is time to replace the planter.
You need to repot less often for older plants. Those who choose a sufficiently large and, above all, deep planter will only have to repot every three to four years.
