Cultivate Palisander tree

The Palisander tree catches the eye. The trumpet-tree plants adorn the roadsides in their native South America and are a very special eye-catcher with their blue to violet panicle flowers. So that our living rooms and conservatories become a welcome home for the bizarre exotic, some care instructions are to be considered, which can be read below.

The Palisanderbaum as a houseplant

As an ornamental plant, the Jacaranda tree has quickly made a career. In almost all frost-free zones, the plant is found today. Hobby gardeners in Germany unfortunately have to confine themselves to the Kübelhaltung and cultivate the Palisanderbaum in the room. In summer, the plants on balcony or terrace for exotic charm. The frost-sensitive plants spend the winter in the house in any case.

Why is my palisander tree not blooming?

Anyone who has seen photos or was able to convince himself during the holiday in the south of the impressive flowers of the trees, will now wait and curious and often wonder if a care mistake could be behind the flowering laziness of the ornamental plants.

Unfortunately, gardeners in Germany are mostly disappointed. Jacaranda trees are very small in size. Only from a height of two meters increase the chances of a blue-violet sea of ​​flowers. If you offer enough space for your plant and you have a spacious conservatory or high ceilings, then you can continue to hope for the attractive flower. Otherwise, do not be disappointed and enjoy the filigree feathered leaves.

Water the Palisander tree properly

During casting, the Palisander tree is quite demanding. Casting is only necessary if the substrate feels dry in its surface. Here, the thumb sample is helpful. It is poured abundantly and at longer intervals. This is more digestible for the crop than just giving a sip of water every day.

Danger: Never pour the Palisander tree with fresh and cold tap water.

The plant is preferably watered with rainwater, which was brought to room temperature. If rainwater is not available, you can use stale and softened tap water.

Tip: A bag filled with peat made of linen overnight, suspended in the vessel, for the softening of the water.

If the Palisander tree is too dry, it acknowledges this with leaf fall. Also the air dryness can harm the exotic plant. Do not forget to spray the plant regularly with soft rainwater. Especially dry heating air damages the plant. In summer, the humidity in the room can be increased by frequent bumps. It is also advantageous to set up humidifiers in the room.

Fertilize the Palisander tree properly

The plant has a fairly high nutrient requirement. Especially during the growing season, between April and August, should be fertilized regularly. In this case, add liquid fertilizer to the irrigation water every 14 days. If the plant is wintering in the heated conservatory, it is fertilized monthly during the winter months and in very dilute concentrations.
If possible, use a low-lime fertilizer. Very well suited is a commercial rhododendron fertilizer. More and more hobby gardeners resort to organic fertilizer. This not only protects the wallet, but also the environment. Compost can be mixed in at planting.

Tip: It should be fully mature compost, otherwise the roots could be damaged by incomplete rotting processes.

Horn shavings, bone meal or primary rock flour also provide a complete substitute for commercially available industrial products.

Detecting diseases and pests on the Palisanderbaum

The greatest danger to the plant are the care mistakes of their owners. Otherwise, the exotics are extremely robust against diseases and pests. Only spider mites or whiteflies occur occasionally.

Danger: Pest infestation is favored by a too low air humidity.

If there is an infection with spider mites, the edges of the leaves and the leaf axils appear as if covered by fine cobwebs. The pests are particularly noticeable if you vigorously spray the plant.

If the leaves lose their shape and coloration, white flies can be the cause. The larvae and fully trained insects feed on the leaf juice. Often the whitefly sticks to the underside of the leaves.

If the insect infestation is noticed in time, the showering with a hard jet of water is quite effective. Even with nettle solution or horsetail mud, affected plants can be effectively treated.

However, anyone who has failed to control his plant regularly will probably need to resort to chemical means to destroy the pests and ultimately save the plant.

Remediate diseases through care mistakes

If the Palisander tree has not been treated with the necessary tact, or if the siting is rather unsuccessful, the plant will be gradually corroded from below. If you notice this, act immediately and remove all shoot tips. The Palisanderbaum will then form again below new shoots.

If the stand is too dark or over-watering it may cause leaf fall. Even low humidity leads to the drying and falling of the leaves.

Healthy plants through proper care - that's how it works


Choose a bright, but not sunny spot. Before the blazing midday sun, the plants are to be protected. The Palisander trees are sensitive to frost and must spend the winter in any case in the house.


The planter should have sufficient size and depth to allow the jacaranda to grow well. Terracotta planters provide stability on windy days outdoors. In the plant pot enough drain holes for the irrigation water must be present so that it does not come to waterlogging.


The substrate should be as loose and permeable as possible. The irrigation water must not accumulate in the container. A good choice is Rhododendrons Earth. Compost or horn shavings enhance the substrate. Calcareous soil is not tolerated.
