As far as I know, Adenium plants have the capacity to be re-grown through cuttings of the mother plant. I tried the last time, but did not bother to take care of it well. But this time, since I had success growing my banyan plant from the mother plant’s cutting, I wanted to try the same method on Adenium as well. After a week, the bigger leaves dried away, and I just assumed the cuttings will take time and left it at that. Now I see new growth in the leaves, but no new roots. I do not want to jinx this or anything, but I am beginning to think that Adenium cuttings can sustain growing in water. Time will tell.
Old leaves shedding and new leaf formation
All the old leaves have withered, tiny new leaves forming
Happy gardening!
