Sometimes it just happens…a branch breaks in a strong wind; a neighbor unknowingly prunes their plant. The fall is NOT the time to take cuttings from plumerias. But sometimes you can’t avoid it. So what do you do?
Your first option is to root it, but that will require heat – most likely a heat mat.
If you can’t root it, then you need to store it. Typically plumeria cuttings don’t store well. It is best to root it soon after cutting it. But the Southern California Plumiera Society asked experienced growers how they store cuttings over winter, and their answers are very helpful!
