What can I do to get my bouganvilla to put on flowering bracts? The plant is full and green, but no flowering.
You may need to add some phosphorous, like bone meal. Here is more information: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/phosphorus-plant-growth.htm

Something is eating my bougainvillea. It's a well established plant and heretofore was vigorous and beautiful. Both the leaves and the colored bracts are affected and at times the plant is nearly denuded. I can't seem to find a culprit. Any ideas?
Any number of insect pests could be responsible for this, including bougainvillea looper. We recommend using neem oil for pests. It is safe for animals and beneficial bugs but will kill any chewing bugs that may be present, even if you don't see them.

How do you keep Bougainvilleas in bloom?
Plants need phosphorus to flower. Bone meal is a good source of phosphorus (https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/bone-meal-fertilizer.htm).
Hello, I have two questions. I have a Sago which is covered in sticky white mess. . . not sure if it's thrips or mealy bugs. How do I rid my plant of this, as this is a recurring issue? Also, my Boginvellia (sp) is not blooming. Its leaves are green but not solid green. I do fertilize and the bush is rather big. Thanks for your help.
It sounds like mealy bugs on the sago. This article will help with that:

If it is a reoccurring problem, this normally is an indicator that the plant is under stress. Make sure that the plant is being properly watered, has the right amount of light and is not root bound. These are the most common stressors.
For the bougainvillaea, I suspect that it may lack phosphorous or have too much nitrogen. Try giving it some bone meal to balance the phosphorous back out. This article will have some other suggestions:

I have a bounganvillia tree and brought it in for winter. Well, now it keeps losing leaves and then they will come back. Is there maybe a way I need to trim tree? Can you help?
It is trying to go into dormancy. The lower light and lower temps are giving the signal to go to sleep. I would actually not worry about it too much. When you put it back out in the spring, it will spring right back in a very short period of time. Next year, you may want to just allow it to go completely dormant for the winter.
