Looks great! Protect the top from rain until it dries up.
Yes, rot travels fast. My neighbor didn't cover their huge plumerias winter time. And didn't prune the damaged tips. When they finally did, after 3 weeks, the entire trees have rotted.
If you look closely there are 2 plumerias trees (1 is closer to the fence) that rotted all the way to the ground.
I'm trying to revive a stump but I doubt it will survive.
I had to cut it more because the rot traveled.
