The Dipladenia Mandevilla can be propagated quite easily with offshoots or cuttings. It is perennial, but unfortunately not hardy. With its decorative flowers, it adorns your balcony or terrace in a special way.
The Dipladenia can be propagated via offshoots
What is the best way to cut offshoots?
First, prepare a seed pot by heating a mixture of one part sand and one part potting compost in the oven at 180° for about ten minutes. This kills any germs that may be present. Pour the cooled mixture into a flowerpot without drainage holes.
Take some fresh or slightly woody shoots of the Dipladenia and cut them in at an angle. These cuttings plug the prepared flower pot. Then they pull a transparent film over the pot and fasten it in such a way that practically no air from the outside gets to the cuttings. The existing moisture is sufficient to sprout new shoots. Place the seed pot in a warm place.
Temperatures of around 24°C to 27°C are ideal. If you cannot reach them in any room, then use an indoor greenhouse. It will take about three to four weeks for the cuttings to take root. Only then do you remove the foil or take the young dipladenia out of the greenhouse. Then wait a few weeks before transplanting into larger pots.
The essentials in brief:
- Cut fresh or slightly woody shoots as offshoots
- cut the lower end at an angle
- stick in substrate sterilized by heating
- keep warm and moist until after successful rooting
- ideal growing temperature: 24 °C to 27 °C
tips
Offshoots can easily be cut from the Dipladenia or Mandevilla and new plants can be grown from them. The cultivation of young plants may also be an alternative to overwintering the old plant.
