DENDROSICYOS SOCOTRANA = CUT & REROOTED

I bought this plant 2 years ago from a succulent nursery at a cactus & succulent fair. I repotted the plant - as I allways do with new acquired plants - and checked it for diseases, mould, pests and maybe surprises. I discovered that the roots were decaying and the base of the trunk was going to rot.

I have had cut the trunk some 10 cm above the base of the trunk, powdered it with charcoal powder and after that with auxin powder. Then the trunk was fixed to a bamboo stick and repotted in my normal mineral substrate mixture. At last the surface was covered with coarse gravels of lime stone.

The plant stood and still stands in winter on a southern windowsill above the heater - to make sure that it does have allways "warm feets" - and was and still is sprayed with warm water - including some fertilizer at very very low concentration.
In the summer time the plant stands outside on the balcony in full sun only shed from rain.

All this started 2 years ago. As you can see this time it is sprouting very densely all over the whole trunk. This very heavy growth happens for the first time. So it is not really easy to reroot or propagate DENDROSICYOS SOCOTRANA by shoots.

In the www people do report that it is not at all possible to propagate this species by shoots and to root those. I can tell you that this is nonsense. It is possible, but you may need the help of growth hormones like auxin or giberellin, heat from underneath to guarantee "warm feets", as much sun as possible and "a loving hand" to do the right thing at the right time.

Now the plant is 80 cm high and as thick as a thumb at its base. The new growth at the top of the plant will hopefully develop into the new trunk.

  1. So the cutting (I guess) didn't show any signs of life for two years after being stuck? Wow, that's pretty insane that the stem tissue of a young plant would be able to stay alive that long without actively growing. Were you watering it during its slumber? How long after replanting it did you start eating it if so?
    Appreciate your time/response, unfortunately my little Dendrosicyos had a run-in with a leaf blower while I was away and seems to be starting to rot at the base, or at least has deflated...

    1. Huh, sorry, "how long after replanting it did you start watering it if so?"
