Besonders einfach: Abtrennen von Ausläufern
Viele Rosenarten bilden, artenabhängig mehr oder weniger stark ausgeprägt, Ausläufer aus, die sich teilweise über mehrere Meter im Garten verbreiten können und auch sehr schnell einwurzeln. Gerade die Gemeine Hecken-Rose oder auch Hunds-Rose (Rosa canina) vermehrt sich selbst durch zahlreiche Wurzelausläufer, ebenso übrigens wie die beliebte Kartoffelrose (Rosa rugosa). Dank dieser lässt sich die Vermehrung besonders einfach bewerkstelligen:
- Trennen Sie mit Hilfe eines Spatens die Ausläufer von der Mutterpflanze ab
- und graben Sie sie aus.
- Die Ausläufer werden um etwa ein Drittel zurückgeschnitten,
- damit sie anschließend besser verzweigen.
- Pflanzen Sie die neu gewonnenen Heckenrosen gleich am gewünschten Standort
- bzw. in einen ausreichend großen Kübel wieder ein.

Runners are obtained either in the spring before budding or in the autumn for propagation.
Propagation through cuttings
In contrast to the only half-ripe cuttings, cuttings are strong, lignified and annual shoots. These are cut in the late autumn before the first frost and kept frost-free, but cold, until they are plugged in the following spring with high humidity. For this purpose, it is best to pack the cuttings in damp sand and store them in a cool cellar or similar.
- Timber cuttings should be about 20 centimeters long.
- In spring they are planted directly in the bed or in a sufficiently deep tub.
- Use a loose and well-drained substrate for this.
- Cut the wood just below the bottom eye and dip this end in a rooting powder.
- After planting, only the top eye looks out of the earth.
- The young shoots that appear soon should be shortened to stimulate branching.

Cuttings are ideally cut between the end of July and the beginning of August, which is why already woody, semi-ripe shoots are best suited. These should be about four to six inches long.
- Remove any flowers that may be present
- as well as all leaves except for the uppermost leafy side shoot.
- Put the cuttings in clay pots filled with low-nutrient seed compost.
- For better rooting, the lowest cut can be dipped in rooting powder.
- Keep the substrate slightly moist.
- Place a freezer bag or plastic bottle (cut off at the top) over the cutting.
- For a better air exchange, you can provide these improvised greenhouses (€ 34.95 at Amazon *) with a few holes.
- The cuttings are placed in a protected, partially shaded location outdoors.
- Remove the plastic cover as soon as the cutting starts to form new shoots.
Tips
Alternatively, of course, it is also possible to propagate using seeds you have collected yourself, but this method requires a lot of patience - it may take up to two years for germination to occur.
