Winter rosewood tree - what you have to pay attention to!

The rosewood tree does not tolerate cold temperatures. Here you can find out what needs to be considered when wintering the Jacaranda.

The impressive blue-violet blossom of the rosewood tree makes the metropolises shine in South Africa and even announces the start of the Christmas season in Australia, which is even sung in a song. In Johannesburg alone, more than 70,000 Jacaranda trees grow, which were imported from South America in the late 19th century. In our latitudes, rosewood trees are rather rare. This is not least due to the fact that the trees cannot be cultivated outdoors all year round in the harsh German climate. But the trumpet tree plant is also attractive as a container plant and an eye-catcher on the balcony and terrace during the summer months. So that you can bring the growth-loving exotic to the winter well, you should take the following tips and advice to heart.

When is the rosewood tree allowed to go outside?

The plant can safely spend the summer outdoors. A bright and sunny location is ideal. The blazing midday sun is however less tolerated by the plants. The plants are at home in the subtropics and are therefore particularly sensitive to the cold. As soon as it gets colder than ten degrees in autumn, it's time for Jacaranda to move into the house. In spring you should wait until after the ice saints. Depending on the weather, the trees should not be outdoors until late May or early June.

What should you watch out for during the winter?

From the end of October to the end of January, a rest period began for the plants. The plants are then watered only sporadically and do not receive any fertilizer.

Tip: The earth should not dry out even in winter quarters. Therefore, the plant should be checked regularly and watered if necessary.

The ideal winter quarters have a temperature of 15 to 17 degrees. The Jacaranda should overwinter brightly. The ideal locations are a heated greenhouse or a winter garden. Since not every plant lover can offer these winter quarters, the living room or the heated hallway can also serve as alternatives. It is important that the plant receives sufficient light and is not placed in the immediate vicinity of the heating.

When should you move to the winter quarters?

As already mentioned, the plant cannot tolerate a permanent drop in temperature below ten degrees. This suggests that the move date is already in late summer. Plant experts are of the opinion, however, that it is better to postpone the move. Contrary to popular belief, the rosewood trees can tolerate lower temperatures for a short time, even down to the single-digit minus range. Due to the slowly falling temperature values, the plant is hardened. At the beginning of October at the latest, however, it is definitely time to move to the winter quarters.

What happens if the plant is exposed to constant cold?

You should not dare this experiment because it would definitely mean the end of the plant. Persistent low temperatures would cause the water in the plant cells to freeze. The cell walls would be blown up and the plant could no longer be saved. So you better not do any experiments and rather rely on moving to the warm winter quarters instead of hardening.

Course of the year for the rosewood tree

  • Moving outside from mid-May
  • Summer on the balcony or terrace
  • October move to the winter quarters at the latest
  • Wintering at around 15 degrees

When the move can take place outdoors should be made dependent on the respective weather conditions. From mid-May it should be ensured that the temperatures no longer drop below ten degrees permanently. The move should be gradual and careful. Do not expose the plant to full sun immediately. First choose a shady place and after about a week move the bucket to the desired warm place in the sun.

The jacaranda tree can spend the summer on the balcony and terrace. The plant must be protected from direct sunlight and watered regularly. So that the wind does not knock the tree over, the planters should bring a certain weight. Terracotta is ideal for this.

If the temperatures permanently drop below ten degrees, the move to the winter quarters is pending. You should also do this step by step. The plant therefore initially moves into the shade for a few days before it can finally move into the house.

The right care in the winter quarters

The rosewood tree must not be left to its own devices in the winter quarters. Regular inspection is important to assess the water requirement and to check the plant for any damage. If the plant sheds its leaves, this indicates a maintenance error. The Jacaranda is usually too dark or has been cast too little. To prevent the leaves from drying out, you should spray the rosewood tree more often.

Tip: The rosewood tree is not mulched in winter. You can use the thumb test to determine the water requirement better.
