In order for the exotic Tibouchina urvilleana to develop a bushy silhouette and abundant flower abundance, it requires repeated pruning. Plenty of plant material accumulates for uncomplicated propagation. Anyone who loves the challenge as a hobby gardener, will also like to try on a offspring by sowing. Both methods can be read here. In order to ensure that the young plants used by hand come through the cold season in the first and all the following years, this guide also explains all the important aspects for successful wintering.
Since a Tibouchina urvilleana branches only very hesitantly of its own accord, a three-time pruning a year is one of the fundamental care measures. After each cut, you also hold a wealth of premium material for propagation in your hands. This is especially true after the first cut in March. Follow these steps:
- The perfect cutting is 10-15 cm long and healthy
- The cut was just below a bud
- In the lower half, each offshoot is defoliated
- Small seed pots fill with peat sand or lean substrate
- Insert one clip at a time so deep that at least 1 pair of leaves protrudes
- Sprinkle with lime-free water at room temperature
Tip: If cuttings of a violet tree are poured from below, this method reduces the risk of rot and mold. For this purpose, the pots for a few minutes in a bowl with a 5-10 cm high water level. If the surface of the substrate feels damp, the branches change back to their original place.
At the latest when the tender roots grow out of the bottom opening of the culture container, it is time to move to a larger pot. The substrate is now a high-quality potted soil, which uses expanded clay, lava or styrofoam pellets and a little sand to provide more permeability. So you pot the young plants with expertise:
- The new pot is no larger than 5 centimeters in diameter
- Above the bottom opening, a potsherd prevents harmful waterlogging
- Half fill the vessel with substrate and press in a well
- Pop the former cuttings and plant them in the middle
- The fresh soil reaches almost to the bottom pair of leaves
Tip: They promote a lush branching when the shoots of a young princess flower are regularly rejuvenated.
If the Tibouchina urvilleana spent the summer on the balcony or terrace, pollination by bees or bumblebees took place, resulting in the growth of capsule fruits. These can be harvested for the production of seeds for propagation by means of sowing. From a pure-bred offspring is not to go out with this method. Just let yourself be surprised what attributes of parent and grandparent plants prevail. Alternatively, the specialized trade holds certified seed. Although the seed can be sown all year round, the ideal spring is the end of February / beginning of March. The lighting conditions are bright enough from this point on, so that the young shoots do not hurry. So the offspring succeeds by seeds:
- Fill a heatable seedbed with seed soils such as peat sand or coconut
- Spray the substrate with room-warm, lime-free water
- Then sow the light germs and just press on
- Cover a plastic wrap or spend in the indoor greenhouse
If the first true pairs of leaves flourish above the kedge leaves, the seedling shell is in a tight spot. High time for the isolation, because leaves constantly touching leaves cause rot formation. How to skillfully stroke the young plants:
- Half fill small pots with Pikiererde
- Throw a small trough into it with the Pikierstab
- Use a spoon to lift out the seedling, including most of the earth
- Place in the trough and fill with substrate up to the cotyledons
- Press the Pikiererde with the rod and pour
Hibernate at the right location
When the outside temperature falls below 10 degrees Celsius, it is too cold for the exotic Tibouchina urvilleana in the open air. Now she changes to a wintering place, which is like this:
- Bright and not too warm, with temperatures around 15 degrees Celsius
- A place at the south window or in the light-flooded, heated conservatory is ideal
- There is no active radiator in the immediate vicinity of the location
Care in winter
The water and nutrient supply is adjusted during the cold season on the reduced metabolism. Therefore, do not water the princess flower until the substrate surface has dried. To do this, press your thumb into the ground. If the upper 4-5 cm feels dry, it is cast. The administration of fertilizer is waived from December to March.
Since the dry heating air offers the spider mites ideal living conditions, the violet tree is repeatedly sprayed with lime-free water. In this direction also aims to fill the coaster with water and pebbles. The evaporating water permanently spreads the plant, so that moving spider mites do not even settle. Commercial humidifiers, bowls filled with water and an indoor fountain also contribute to increased humidity, which also benefits human health.
If the cultivation of a Tibouchina urvilleana is successful, the desire for further specimens grows. For the ambitious hobby gardener, the self-propagation of this tropical flowering plant is a matter of honor. Good to know that both offspring by cuttings as well as by sowing is to be mastered. It is important to note some fundamental requirements, such as a sufficiently warm temperature of 22-25 degrees both for rooting of cuttings and germination of seeds. In order for you to enjoy the princess flowers over many years, the requirements for hibernation must not be underestimated. The winter quarters should be bright and not too warm, with a reduced supply of water and a renunciation of the gift of fertilizer. Keep cunning spider mites at a distance by periodically spraying with lime-free water to get the violet tree through the cold season.
