I use to use both bone meal and blood meal but stopped using those products many years ago. I had "critters" digging in my landscape and pots, attracted by the scents of those two products. I do use Bloom fertilizers though. I typically use a general purpose, balanced fertilizer when I put my plumeria outside, but after there is good leaf formation. After 4-6 wks., I will use Bloom fertilizer every third feeding. By mid-August, I don't use the Bloom fertilizers any longer. Then around mid-September, I quit fertilizing altogether, unless the plants are in bloom, and I continue fertilizing them, using 1/4-1/2 the recommended dilution rate. I will continue this weak fertilization even into winter for those in bloom and in the solarium.
For all I know, since I am anything but expert here, I am breaking every rule in the book. I just do what seems to work for me with my climate and my growing conditions.
