I have a Frangipani bush that is about 3 years old. It flowered beautifully the first year, but the past two years it hasn't. Instead, it's just grown enormous.
It sounds like it may have too much nitrogen. When a plant has too much nitrogen, it will grow lush and large but will get few flowers. If you are using fertilizer on it right now, cut back. Also add some phosphorous to the soil to help balance the nitrogen and phosphorous. Phosphorous will help get the plant blooming again.
Have a frangipani that was hodden when we move in under a dense tree/bush. It has been fighting for light and leaned over. Sturdy trunk about a meter high, but only leaves at the top. We have removed the overgrown tree. But now unsure weather to leave ot ro its own devices, stake it. (It does lean badly), or wwther to cut it off the top, bit this would leave no leave ans ther is no other branxhes
I would stake the plant for now, to help ensure it does not suffer damage or break.
If you are going to transplant it to another part of the garden you will need to do some planning.
You will want to do some root pruning this season to move next season.
By taking a sharp shovel you can sever the large roots around the plant. This will then encourage the Plumeria to start to grow smaller roots in the area that will be moved.

On my balcony facing north, I have a frangipani in a large pot doing extremely well but suffered in yesterday's heat. It had been well watered in the morning but the leaves had bent down by late afternoon yesterday. It faces nth west so the sun was on the plant quite a while from the west. I plan to put umbrella over this later today. My question is it O.K. to spray the leaves with water to help cool the plant or is that detrimental? thank you
It would not be recommended to spray the leaves down.

I have been given 2 rooted frangipanis - approx 2-3m high - and am wondering if I can bind them together at the root base and plant. Will this work, or am I only going to kill one or both of them in doing so?
You can do this I guess, although I am not sure why. Maybe you don't have space to plant both, or for a curiosity in appearance, like having different color flowers on what appears to be one plant?
I would say okay for short term expectations (5 year plan at most), but not the best idea for longer term growth without becoming problematic with structural issues and pruning maintenance.
Hi, I picked about 2 dozen broken Frangipani branches out of rubble piles in the street following Hurricane Irma in Florida (less than two years ago). I planted some outside in pots and some in the ground and about 15 are growing well. The potted plants are doing better than those in the ground and are the only ones to flower prior to the 2 year anniversary of the hurricane, not sure why. Just FYI :)
, replace with other tree. Is this risky because they’re dormant now? I have similar question about grass by seed? Will the lawn grow at this time of year or seeds wash away?
For both issues, transplanting the frangipani (plumeria) and seeding grass, there is an advantage of waiting until your early spring when new vigorous growth will get them off to a good start.
uning? I've cut off the lower branches and there's new growth. Do I cut down the entire tree as all branches seem to be affected.
You will need to, manually, remove all that you can. What you cannot reach may need to be cut off. Pesticides will not penetrate their seal once they are stuck to your plants, however it can prevent eggs from hatching, or kill off those that have not attached yet.
