Is there a trick to get my Adenium Boehmianum to sprout new branches? It has never grown any more branches than when I bought it more than 5 years ago. I just repotted it in proper soil with lots of drainage holes in the pot. I am in AZ and it has just started sprouting leaves. It goes into the garage when temperature drops below 45 degrees. I must admit I have not been good about fertilizing.
So, I knew nothing of this plant before today but I read a really interesting paper put out by the University of Florida that provided the advice below.
There's a few different types of adenium boehmianum, and some are naturally bushy while others tend to have just a few stems until they mature fully.
If your Adenium Boehmianum is getting leggy and you need to encourage branching, pinch back or remove a few inches of stem. Prune just above the leaves and it will be more likely to result in multiple branches than if you prune further down on the plant on bare stem. You can do this once a year, preferably from February to September. Trying to do this during winter often fails to generate healthy branching. If you do any of this be VERY careful. The sap, I'm sure you know, is highly poisonous.
If you provide pictures of your plant, someone may be able to help you further.
