Mimosa plants are often grown as annual plants because they do not overwinter well. You don't have to repot annual mimosas. If you grow the plant as a perennial, you should transplant it as soon as the roots grow out of the pot.
When and how should you repot a mimosa?
A mimosa should be repotted when its roots outgrow the pot or the root ball completely fills the pot. Use fresh substrate, a new pot and carefully fill the plant. Then place the mimosa in a bright, warm location and do not fertilize immediately.
When do you need to repot the mimosa?
It's time to repot the mimosa when the roots grow out of the drainage hole at the bottom. Even if the root ball completely fills the pot and comes out of the top, it's time to give the plant a new, slightly larger pot.
Ideally, you should repot the mimosa in spring. But check regularly whether the roots still have enough space in the planter.
Newly purchased mimosas should be repotted immediately after purchase. The pots are often too small and the substrate is too exhausted or too moist.
Do not choose a pot that is too large
The roots of the mimosa must be able to spread. However, a pot that is too large is not recommended. The leaves of the mimosa appear much more decorative and the plant also blooms more beautifully in a smaller pot.
The planter must have a sufficiently large drainage hole so that no waterlogging can form.
How to repot correctly
- Unpotting mimosa
- shake off old earth
- maybe. Pruning roots
- Fill pot with fresh soil
- Insert plant
- Press the substrate carefully
Carefully take the mimosa out of the old pot. Shake off the old soil. Check whether the roots are still he althy. If necessary, you should cut rotten and diseased roots before moving them to a new pot.
Prepare a pot with fresh substrate and plant the mimosa carefully. Press the soil lightly and water the plant.
After repotting, you must not fertilize the mimosa at first. Place the pot in a bright, warm location. Avoid direct sunlight at first.
Which plant substrate is suitable?
Simple compost or potting soil (€6.00 on Amazon), which you loosen with a little sand or fine gravel, is suitable as a plant substrate.
Tip
After repotting, the mimosa leaves look very torn and worn out for a while. That is normal. After a while they recover.
