How does seed pod formed? From what I gathered through my reading on the internet, the seed pod is formed when the flowers from the Adenium is pollinated by insects. Adenium does not self-pollinate.
This is the oldest Adenium that I have grown. I have kept this plant for 10 years has 3 pairs of seed pods on it. This is another first time for me. Usually I will only have one pair of seed pod on this plant.
If you see the first photo in this posting, all the seed pods have symmetrical length seed pods. However, my 2nd pot of Adenium shows stunted growth on one end of its seed pod (refers to pink arrow). I don't know why this happen.
My 3rd pot of Adenium shows one healthy pair of seed pod.
My 4th pot of Adenium shows 2 pairs of new seed pods. They are still very young. I hope the seed pods will grow well.
The above is an old photo of Adenium seeds that my friend, Chooi, gave me. I have tried to germinate the seeds and eventually only two turned out well to be the 2 young Adenium seedlings below that I have recently transplanted into bigger pots.
From the GSC Forum, I have learnt some tips to grow big caudex for Adenium. I have pinched some leaves on the top of the plants with the hope that this would made the caudex grow big, instead of the plants growing tall. Pinching of the leaves can only be done after there are 3 pairs of leaves on the seedling. Not before that as the plant would still be too young. Covering the root with lotsa soil can also help to make the caudex grow big.
