What is the best way to cut offshoots?
First, prepare a growing pot by heating a mixture of one part each of sand and potting soil in the oven to 180 ° for about ten minutes. This will kill any germs that may be present. Pour the cooled mixture into a flower pot without any drainage holes.

Take some fresh or slightly woody shoots of the Dipladenia and cut them slightly diagonally. These cuttings stick in the prepared flower pot. Then they pull a transparent film over the pot and fix it in such a way that practically no outside air can get to the cuttings. The existing moisture is sufficient to drive out new shoots. Put the nursery pot in a warm place.
Temperatures of around 24 ° C to 27 ° C are ideal. If you cannot reach this in any room, then use an indoor greenhouse. It will take about three to four weeks for the cuttings to be rooted. Only then do you remove the foil or take the young dipladenia out of the greenhouse. Then wait a few more 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
From the Dipladenia or Mandevilla, cuttings can easily be cut and new plants can be grown. Rearing young plants may also be an alternative to overwintering the old plants.
