Repot the poinsettia every year
You should repot a poinsettia every year, even if the pot is not too small. The ideal substrate for poinsettias consists largely of peat, which decomposes over the course of the year. The soil should therefore be replaced regularly.

If you can continue to use the old pot, clean it thoroughly before you plant the poinsettia again. New pots should also be completely clean so that no germs or fungal spores can spread.
The best time to repot
A poinsettia is repotted in spring after flowering. Later on, you should only transplant it if you need to save it from dying.
Prune roots when repotting
- Cut off dead inflorescences
- Rinse off old soil carefully
- Shorten sick, dry roots
- Fill the pot with fresh substrate
- Insert the plant and press it down
- keep moderately moist
Carefully remove the poinsettia from the pot. Rinse the old substrate under running water.
Look closely at the root ball. Cut off any roots that are dry or rotten. When growing a poinsettia as a bonsai, reduce the root ball to keep the plant compact.
Put the poinsettia in the pot and carefully press the fresh substrate into place.
Care after repotting
After repotting, do not keep the poinsettia too moist. Above all, avoid waterlogging. Fertilization is not necessary in the first few weeks after transplanting, as the fresh substrate contains sufficient nutrients.
If you have the opportunity, you can cover the poinsettia on the balcony or terrace. Otherwise keep it on the window sill.
So that the poinsettia can develop its colored bracts, you must first put it in a dark or darker color for a few weeks.
Tips
Poinsettias usually recover very quickly from repotting. But give the plant a grace period and do not place it directly in the sun for the first few weeks.
