If you don't have a garden, you don't have to do without beautiful roses. Many varieties - especially among the bed and dwarf roses - can also be cultivated in tubs without any problems. So that you can enjoy your potted roses for a long time, you should repot them regularly and not only provide them with a larger container, but also with fresh substrate.
Regular repotting of potted roses is important so that they have enough space to grow
The right time to repot the roses
Although potted roses - like any other container rose - can basically be repotted at any time, provided the temperature does not drop below zero, it is still advisable to carry out this measure in autumn. Repotting is always a shock for a plant, which can cause roses that are full of juice to drop leaves and flowers - also because damaged roots can no longer absorb enough water. In autumn, however, the rose gradually goes into hibernation, so there is no shock. For the same reason, repotting is also possible in early spring - before the first budding.
Repotting roses - this is how it's done
Roses should be repotted every two to three years, because by then the original pot is already too small and most of the substrate has been used up. Now put the rose in a new, larger container and replace the soil completely. By the way, make sure to use pots that are as round as possible for potting, which widen towards the top (and not narrow!) or are evenly wide both at the top and bottom - angular and unevenly wide pots will make repotting much more difficult for you later, because the larger the plants, the harder it is to get them out of the container undamaged. After repotting, water the rose thoroughly!
What to do with very large plants?
Very large roses or tied climbing roses are often difficult or impossible to get out of the pot. In this case, you no longer repot the plants, but simply refill them with fresh substrate on a regular basis. Above all, fertilizing is very important with these roses!
tips
If your tub roses are already quite large, before filling the pot with soil, first lay out the garden fleece so that it protrudes a few centimeters at the top edge. The next time the rose needs to be repotted, a helper will hold the pot and pull it down - and you grab the fleece and simply lift the rose and its roots out of the pot. This way the roots are not damaged and your plant will survive the procedure better.
