Plants that have been standing for a long time should be repotted from time to time. We show what needs to be considered and how to repot correctly.

Fresh substrate and a larger vessel promote the growth and vitality of the green protégé. Depending on how often you repot, you should choose the size of the new container. If the plant is granted a new container every year, it is sufficient if this is a few centimeters larger. However, if the next repotting takes up to three years, the new container should be between 5 and 10 centimeters larger in diameter than the previous one.The new pot should be big enough [Photo: Iryna Imago/ Shutterstock.com]How often the plants have to be repotted depends on the species in question, just like the choice of the right substrate. When it is time to repot, you can easily tell from the root ball. If this is completely rooted, you have to change the substrate and move it to a larger pot. In general, it can be repotted all year round. But it makes little sense to repot before winter. The growing conditions are unfavorable and without improvement of the growing conditions temperature and In light, the plant finds it very difficult to form new roots and with them into the new substrate to advance The start of the natural growth phase in early spring, on the other hand, is the optimal time to carry out the necessary repotting.
1. Repotting - yes or no?! The right time
You can tell from the root ball whether it's time to repot your beloved plants. If this is very heavily rooted and only a little substrate is visible for the roots to conquer, it is time for a new pot with fresh substrate.

2. Get out of the old pot and loosen up the bales
Before the plant is placed in the new pot, it is a good idea to loosen and tear up the root ball. This allows air to get to the roots and stimulates the formation and branching of the roots.

3. Fill with fresh substrate and press down
The slightly larger new pot is filled with the new substrate around the plant to be repotted. The still loose, filled edge area in the container is now pressed on a little. When choosing the substrate, rely on a high-quality and peat-free organic soil that exactly meets the needs of your plants. In our Plantura shop find sustainable and CO2-reduced organic soils for different plants.
4. Cast on and back in place
Before the old plant can return to its usual place in the new pot, it needs to be watered. It is important to strike the right balance between too little and too much. If you water too little, you run the risk of letting the old root ball dry out. This is then difficult to re-wet. If you water too much, the plants are quickly attacked by dangerous root fungi.
