Thank you Dutchlady1. We were really careful and yes a lot of roots were left.
The rest of the large leaves I clipped off but some of the tiny ones seem to be fine this morning.
I will certainly keep you updated.
I'm fairly new to Plumerias. You've mentioned they will go dormant in the colder months. Will this affect us here as well since it actually never really gets cold (75F / 24C in January)?
Thanks again!
