Hello Bondex....
I have rooted 7 Plumeria here in NY last spring and 2 have flowered nicely. (one flowered in OCT and went dormant over the winter and its flower stalk is rebudding and will produce flowers again this spring !)
I used Spray-n-Grow Bills perfect Fertilizer and Macro nutrients kit .(

I repotted all the plants 2 weeks ago and was first chance i had to look at root system and all plants were strong and very healthy. I've only had 1 season of experience with it but i think its worked well and the plants all seem healthy, and the plants that flowered had sturdy inlo's and large flowers.
Give it a shot. Its a fertilizer you spray on the leaves instead of watering directly to soil.
