Repotting plants: this is how you do it right, You should replant potted and tub plants in the apartment or on the balcony from time to time. You stimulate the growth of your plants. You also strengthen the health of your potted plants. We explain when you should repot your plants, how to do it and what you should pay attention to.
Repot step by step
Plants that grow in nature can spread more or less unhindered. They are not restricted in their growth. It’s different with potted plants. The flower pot or planter on the balcony limits the growth of the plant. Because if the roots cannot spread, the above-ground part of the plants will not continue to grow either. By repotting you stimulate the growth of your plants. They look healthier, sprout again and often even begin to flower. We explain step by step how to repot your plants properly.
A plant grows in a pot until it reaches its limits. This is especially true for the roots. They grow in balance with the aerial part of the plant. Only when the root system can spread does the above-ground part also grow. After all, the plant needs to be supplied with nutrients and water. The roots take care of that. If the roots cannot grow any further, the above-ground part of the plant stops growing. The plant no longer grows, no longer flowers or, in the worst case, becomes ill or susceptible to pests because it is no longer optimally supplied with nutrients.
When should I repot plants?
In order for your plants to grow and thrive optimally, you should repot them at intervals of 1 to 3 years. This depends, among other things, on how fast the respective plant grows. You can easily check whether you should repot your plant. Carefully lift the whole plant out of the flowerpot. If the soil is complete and densely rooted, you should repot.
For potted plants that are outdoors, you should wait until spring. The best time is just before growth starts again in spring. This time is also indoor plants the most suitable Because many indoor plants take a break from growing in winter. This is mainly due to the fact that there is significantly less daylight available in winter.
This is how you choose the right pot
When repotting, you should choose a larger pot for your plant. However, a pot that is too big is just as unfavorable for your plant as a pot that is too small. It is best to choose a vessel that is about two to three sizes larger than the previous vessel. This corresponds to an approximately two to three centimeters larger diameter.
Larger plants that don’t grow fast anymore don’t need to be transplanted quite as often. In this case, you should choose a slightly larger container when repotting. It should be about five to six centimeters larger in diameter than the old one.
Preparation for repotting: You need these things
You need a few things to repot. It is best to have them ready before you begin. You need these things:
- New planter with drainage hole in the bottom. This can be a plant pot made of clay or plastic, for example
- A matching planter or coaster
- Some coarse gravel, potsherds or hydrogranulate for a drainage layer
- potting soil
- Possibly a sharp knife or strong scissors/secateurs
- Small garden shovel if needed
- A suitable base if you repot in the apartment or on the balcony
That’s how you repot
When you have done all the preparation, you can start repotting. This is how you do it:
- Prepare the new planter. To do this, fill in a drainage layer made of gravel, potsherds or hydrogranulate. Put some potting soil on top.
- Remove the plant from its pot and examine it for possible pests. If you discover pests such as aphids, spider mites or scale insects, you should treat them.
- Check the root ball. If you discover dead or rotten roots, remove them with a sharp knife or (garden) shears. If the root ball is very heavily rooted, loosen it up a bit. To do this, gently press it together slightly from all sides. This will also loosen old soil.
- Now place the plant in the new, prepared pot. It should be about deep enough in the pot that the top edge of the root ball is a little more than an inch below the edge of the pot.
- Fill the potting soil evenly up to about one centimeter below the edge of the pot. In particular, make sure that the soil gets into the space between the root ball and the planter.
Water and fertilize after repotting
After repotting, you should water your plant vigorously . This ensures that the fresh soil is also flushed into smaller spaces and that the roots have good contact with the soil. Make sure that excess water can drain off easily if necessary.
After repotting, you don’t need to fertilize your plant for about eight weeks. The fresh potting soil already provides fresh nutrients for your plant. After eight weeks you can fertilize your plant again as usual .
Earth is not equal to earth
There are many different types of potting soil. You should definitely use a suitable special soil for cacti, orchids or bonsai. You can universal potting soil . In any case, you should opt for a high-quality product from well-known manufacturers. Cheap earth often starts to mold quickly. The nutrient content is also usually not optimal and the soil often compacts faster than with more expensive products.
It also makes ecological sense if you choose a peat-free or low-peat soil. You can find such products more and more often in stores.
Houseplants and potted plants should be repotted regularly. You promote their vitality and growth. You should repot young plants more often. Large plants, on the other hand, no longer need to be repotted as often. Spring is the best time to repot. When repotting, pay attention to the size of the new pot and use high-quality soil. It’s a bit more expensive, but you’ll have less trouble with it in the long run.
