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

Can I cut the brown long seed pods off of my Plumeria without hurting the tree?
The seed pods are only occasionally produced by the Plumeria.
Some cultivators are sterile and never produce seed pods.
You can remove them from your plant.
If you want to propagate the seeds, leave the seed pods on the plant until they are dry.
This can take 9 to 10 months.
The seeds can be planted right away.

I have a Plumeria with two main stalks on it coming from the base stalk. One stalk is single and straight, the other stalk has trifurcated into three little stalks. Is it possible to force bifurcate the stalk with single straight? Either with string or wire across the tip. Would this harm the plant? I do not want to graft; I do not like the look of it. Thanks Michael
There is no way to 'split' or bifurcate a stalk, in any research that I have found.
Cutting into the stalk would likely result in the loss of the stem or reduce the health of the plant.
Pruning will of coarse, result in multiple branching from the prune site.

I have a plumeria, which I bought in Hawaii back in January. I have it in a pot in my home. It just began to bloom this month; however, it flowers and then in a day or 2 the flower drops off. What is going on? I live in Virginia.
I suspect that your plumeria does not have enough humidity. These plants like a high humidity environment and will shed flowers much more quickly if they do not get the humidity that they need. You may want to look at trying to put the plant on a pebble tray to bring up the humidity around it. Here is more information on that:

What would be the smallest size container to further the growth and flowering of my new leafing out plumeria?
The soil content and fertilization are probably more important than the actual container. Since they need good drainage, avoid planting your Plumeria in a pot that will force it to become rootbound at a very young age. Here are some tips that may help you: https://www.gardeningknowhow.com/ornamental/flowers/plumeria/growing-plumeria.htm
We have a 6 1/2 foot plumeria that just branched into three 8-inch branches and it is top heavy and falling over. The whole trunk of the tree is 2 inches in diameter. Can I cut 12 inches below the three branches (on the trunk) and cut 12 inches above the soil on the trunk and splice the two pieces together? The diameter of the trunk is very even at these two cutting locations. Is this a good idea? Is there a better idea? Thank you for your help!! Patrick
Yes, you can prune your Plumeria.

The new leaves coming are deformed in shape. What could be the problem?
Often deformed leaves can indicate a pest issue.
Inspect the leaves for signs of pests.
Neem Oil is a good treatment and also works as a fungicide.
Plumeria can often be effected with Rust fungus also.
Here are some links with more information.
