Hi, It looks like you're doing well with your plumie. The fertilizer you have will work well. Just follow the directions, and I usually cut it down by half, just to be safe. I have been advised to use Excalibur granular food for plumerias and they have started looking better since I used that instead of Miracle Grow or Osmacoat. Here is a link for it. It is expensive, but lasts a very long time.
