In the limited substrate volume of flower boxes and tubs, balcony plants depend on regular repotting. Beginners underestimate the importance of this care measure or are not familiar with the correct procedure. After reading this guide, beginners will be familiar with when and how balcony plants are perfectly repotted.

The best time is in spring
Repotting is the ideal revitalization cure for all balcony plants that overwinter on the windowsill or in the basement. Spring is therefore the ideal date. For annual flowers in boxes and tubs, it can make sense to switch to a larger container in the middle of summer. Stunted growth, dwindling blooms and urgent tightness are typical signals to repot balcony plants in summer.
Proper preparation is half the success - tips & tricks
The new vessel should be large enough that there is at least 2 finger widths between the root ball and the wall. There may be no openings in the bottom so that excess water can drain off. Please lay a drainage made of potsherds or expanded clay (€19.73) over the holes in the ground as effective protection against waterlogging. Match the fresh substrate to the species of plants that will put down their roots in it.
Step-by-step instructions - how to repot expertly
Once the flower box (€16.99) and tub are prepared, move the balcony plants to their new home. Follow these steps to get it right:
- Fill in fresh substrate halfway up the box or bucket
- Repot each plant individually to shake off or spray off the old soil
- Cut off dried, dead roots and shoots
- Place the root ball on the substrate and fix it with one hand
- With the other hand, fill up with soil up to 2 cm below the edge
It is important to note that your balcony plants are not lower or higher than before after repotting. Press the soil down with your hands to prevent voids from forming. Finally, water the root balls thoroughly with stagnant water.
tips
Substrates for balcony plants are usually pre-fertilized. The supply of nutrients is sufficient for 6 to 8 weeks. Do not fertilize flowers, perennials and shrubs after repotting until after this waiting period.
