Repotting Houseplants

Are your plants looking a little cramped and lacklustre? It could be time to give them a bigger, better home in a new pot. 

When is the best time to repot your plant?

The best time to repot plants is at the beginning of the growth period – this will vary per plant, and could be summer, winter, autumn or spring. To prevent your plants from being undersupplied, they should be repotted at regular intervals. 

Our team doesn’t recommend repotting a plant during its rest period, as moisture can accumulate in the soil and the roots can begin to rot. The following generally applies: houseplants should be repotted every two to three years. Alternatively, if it is a large plant, it is often sufficient to remove the top layer of soil and replace it with new, nutrient-rich soil.

Step 1: How to tell if your plant needs to be repotted

You can usually tell the right time for repotting by the fact that roots appear on the surface. The reason for this is that over time, plants produce more and more roots, which take up all the soil in the pot. Roots showing on the drainage hole are not a certain sign that you should repot. If you want to be sure, lift the plant out of the pot; it will allow you to inspect the existing roots. Repotting is also necessary when a white crust can be seen on the soil, as this may be the result of using water that’s too hard or due to salinisation.

Step 2: Choose the right pot

The new pot should be approximately 2cm larger than the previous one. Clay pots or plastic pots can be used here, but the advantage of using a clay pot is that the water can evaporate more easily and water-logging occurs less frequently.

Step 3: Remove the plant from its current pot

The root bale can most easily be detached from the plant container for repotting when the substrate or soil is slightly dried on the surface. Lift the plant out of the pot and place it in a water bath. 

Step 4: It’s time for a little root maintenance

Old and dead roots must be cut off before replanting. It is also good to loosen the roots a little. 

Step 5: Prepare the new pot for your plant

Fill the new, larger pot with a drainage layer, for example fine gravel, polystyrene balls or expanded clay, and follow with a layer of humus-rich plant soil. Place the plant in the centre of the pot so that it is at the same height as in the previous pot. 

Step 6: Settle your plant in its new home

Fill the flowerpot completely with soil, making sure to add soil right to the edges of the pot. (Remember, however, not to fill the pot right up to the rim so that you have some “air” for watering.) Then press down lightly, and you’re done – it’s time to congratulate yourself on being an A+ plant parent! After repotting, you should not forget to water so that the gaps in the soil are filled.
