You always want to remove all the leaves from a fresh cutting so they don't draw all the moisture out of the body of the cutting. It's going to need that sap to grow roots.

These are some useful things I've learned in rooting plumeria cuttings:

1. Root in the growing season. Spring is best but summer works, too.
2. Water the mother plumeria tree well the day before cutting. (If
it's a cutting from someone else's tree, the healthier it is the more
likely it is to root.)
3. Callus the cutting at least a week. In other words, let the cut end dry out and harden. (All leaves should be removed immediately after cutting.)
4. Use a clear container for rooting, then you can actually see those roots!
5. Coir and perlite seem to be the materials least likely to cause rot.
6. Put the cutting in shade outside. The clear container will create sunburn if not in shade.

7. Water only once, when you put the cutting in the container.
   8. Forget it exists for the next two months. Seriously, FORGET it!
   Don't touch it, don't move it, don't water it. (Rain won't hurt it in
   my experience, but tap water is another story.)

Hopefully after 1-2 months the leaves will begin growing back and you'll know the rooting process has begun.

Awesome advise...

Bottoms heat is helpful too.. Natural ( concrete) or seedling heat mats that I use in greenhouse. I have to watch the rain on my cuttings.. We get it almost everyday from storms..
