I have had a plumeria in the mountains of Panama (4,650 ft elevation) for about 5 years. It is planted in our backyard and has 3 branches coming up from the branch union near the ground. The 2 tallest branches are about 5 ft tall and the plumeria has never flowered. Last year I discovered that it had been planted in a very confining rocky hole with poor drainage. I removed it, widened and deepened the hole and put in much better soil to provide better drainage. It has produced more leaves since then but still no blooms. I have fertilized it with the appropriate fertilizer. Should I prune it to encourage more branching and perhaps flowers? Also, here in Panama, we have a dry season from Dec-mid May and a rainy season the rest of the year. Given this climate, when is the best time to prune and fertilize? Is the timing different than for the rest of North America? Thank you.

I would check the Nitrogen level on the fertilizer you have been using.
To high of Nitrogen can inhibit flowering.

Thanks for your answer. However, I have been using a 10-55-10 fertilizer so it is low in Nitrogen. And my other question concerned the timing of pruning and fertilizing in Panama as opposed to the rest of North America - same cycles?
