I just stick and push all the fresh cuttings into my " Adenium graveyard" without doing anything, roughly 70% will die and 30% will root. I believe the followings will improve the rooting rate:
- let them dry for a couple of days before planting them
- make a hole instead of push the stem into the soil
- cut majority of the leaves , only keep 3 or 4 leaves
- no water in the first 1 week, but make sure that the soil has some moisture
- soil without compost is better, this to prevent the micro organism to compost the stem, thinking that it is a dried leaves
