If you want to multiply a rosewood tree, you have two options. You can find out which these are and how they work in our guide.© Byron Ortiz - Fotolia.com
Rosewood trees (Jacaranda) are attractive ornamental plants that grow into stately trees in southern countries and with their blue to violet flowers provide a splash of color during the end of the year in Australia or decorate the roadsides in Brazil.
The rosewood tree also thrives in our latitudes, provided that some care instructions are followed and that it is kept in the tub. You can find out below how the Jacaranda trees can be easily propagated.
Rosewood tree multiply by seeds
Propagation by seeds is surprisingly easy. If you follow the steps below, you will soon be able to show your own rosewood tree.
Where do you get the seeds from?
Anyone who already owns a jacaranda tree will still have to obtain the seeds for propagation from other sources. It is very rare that the trees can be made to bloom in indoor culture. In nature, rosewood trees reach heights of between five and twenty meters. The trumpet plants start to bloom from a height of about two meters. However, these dimensions are rather unrealistic for keeping as a container plant.
Back to the seeds. You can obtain these from a specialist dealer for exotic plants or order them online.

But you can also get active yourself and keep your eyes open during the holidays. Holidays in the south can bring you Jacaranda seeds. You don't have to travel to South America to do this. In the Canary Islands, too, there are, for example, rosewood trees as street plants. Seed pods are often found on the ground under the trees. You can use this as a holiday souvenir and use it for sowing at home.
When should sowing start?
The months of February to March are ideal for successful propagation. You may object that the increase in indoor culture can actually take place all year round. This is partially true. Sowing in November, December or January is not recommended. Due to the ongoing heating period, the seedlings could be damaged and wither or become moldy.
Multiply the rosewood tree by sowing - step by step
- Prepare the seed bowl
- Fill in the substrate
- Let the seeds soften in advance
- Sow seeds
- Cover seeds slightly with soil
- Moisten the seeds slightly
- Cover seeds
- Place the seed pot in a bright and warm place
- Keep seeds evenly moist
- Wait for germination
The best way to grow them is in a flat seed tray. Growing soil or coconut fibers are suitable as substrates. Coconut fibers should be preferred here because the substrate is particularly loose and permeable. It is also an untreated natural product.
Before placing the seeds in the soil, let them soak in water for about a day. You can then sow directly. The seeds are only slightly covered with substrate.
Tip: The uniform moistening of the seeds is best achieved with a plant sprayer.
Germination can be accelerated by covering the seed pan. This creates a microclimate that is beneficial for the seedlings. You can use foil or glass as a cover. To prevent mold from forming in the container, lift up the cover every day for ventilation. Warm rainwater should be used for irrigation.
When do the seeds germinate?
The germination time is comparatively short. The seedlings should appear after just eight to 14 days.
What happens after germination?
The seedlings should be pricked out about six weeks after germination. They leave only the strongest plants in the seed pan. After separation, the seedlings no longer need to be covered. If the plants have grown sufficiently and have formed several pairs of leaves in addition to the two cotyledons, the young plants are placed in separate planters and cultivated separately.
Rosewood tree multiply through cuttings
Propagation by cuttings is also quite easy, but the chances of success are less promising than when sowing.
Where can I get suitable cuttings from?
A well-developed mother plant is required to obtain cuttings. Ideally, they already have a rosewood tree or know someone who owns the plant. Cuttings can easily be obtained from existing plants when pruning.
Propagation by cuttings - step by step
- Cut the cutting
- Fill the plant pot with substrate
- Insert cutting
- Water the cutting
- Attach the cover
- Place the cutting warm and bright
- Do not let the cutting dry out
- Wait for rooting
The cuttings occur almost automatically when the rosewood tree is pruned. Choose strong shoots. These should be about 20 centimeters long and have no lignification. Remove buds and leaves from the cutting. Only three to five pairs of leaves should be left on the shoot.
Obtain a suitable planter and fill it with growing soil. The cutting is now put into the ground. Leaves or buds should not be covered with earth. This would cause the shoot to rot. The cutting is lightly poured with room-temperature rainwater and covered with a plastic or glass cover. This simple trick creates a microclimate typical of the tropics and speeds up the process of rooting.
The planter is placed bright and warm. A place directly above the heating is ideal, because then the roots are supplied with sufficient heat. During this time, the cutting should not dry out. The cover has to be ventilated more often so that the air build-up in the container does not lead to mold and rotting.
How long does rooting take?
If the propagation of cuttings is successful, this can be easily recognized by the fresh shoots on the cuttings. The rooting takes place within a few weeks. Watch the planter. Once the roots have penetrated the plant pot, it's time to move it to a larger planter. The young plant is now cultivated like an adult specimen.
How are the young plants properly cultivated?
|What is important?||How to proceed|
|Location||The young plants need a bright and warm location.|
Direct sunlight is less cheap.
The container plant is allowed to go outside in summer.
Frost-free wintering in the house is necessary.
|to water||The fluid requirement is high.|
The young plants are quite delicate and watering should not be overdone.
This can quickly lead to waterlogging, which causes the delicate roots to rot.
The floor should dry slightly before watering again.
By spraying the plant frequently, you ensure high humidity.
|Fertilize||The cultivation takes place in nutrient-poor soil.|
After transplanting into a larger planter, compost can be added to the substrate.
Liquid fertilizer can be administered every 14 days during the growth phase.
|repotting||Young plants grow quite quickly.|
After a year, transplanting becomes necessary.
This is limited to the first years of standing.
Older plants only need to be transplanted every four years.
