Thank you for sharing that info! That is much more sophisticated than what I've done. You are brave to get into Plumerias. They get so big. I had one for a few yrs but it never would bloom. When it got too big to get through a door, I declared it was not practical for me anymore. I know I could have trimmed it, but that seemed like a step back from possible blooms, not a step toward.
Throughout the day, I see reflected light shining in spots where direct can't even reach, when the sun is out. It's been a mostly dreary winter. I'm really glad I made the small effort that I did.
