Recently a lot of the leaves on my hibiscus tree are turning yellow. I have been removing them but each morning there are 8-12 more. There have been several buds that bloomed but only one at a time.
This article will tell you how to fix the problem:

I found it after a few hours with wilted leaves i think quite a good portion of the roots remained intact . Replanted it in the same spot and watered ( it wasn’t fully removed from the soil around half of the roots were still well attached to the ground )
Water your Hibiscus with some water that has both a product called Super Thrive and a Root Stimulator in it. Water it with a fresh batch of said mix the next 4 to 5 times it needs watering. I have had great success with this over the years.
It only has one flower on this stem every month or so which lasts about 3 days but I thought it would have more stems
If you cut off the top 2 inches it will then grow side shoots. Is it getting enough sun? They need full sun to grow and bloom well.

my hibiscus plant and xioria bushes seem to be suffering
Wherever you can get full sun shining directly on the plants. Full sun is six to eight hours but since you are in Florida, your plants may prefer a little afternoon shade so an east location would be good. East gets morning sun, west gets afternoon sun and south is a desirable spot because it gets all day sun unless there are trees.

My hibiscus is on the patio and is clean and thriving . Lots of buds and beautiful flowers, but the flowers fall off before the end of the day. I give plenty of water now that the buds are opening. ?? Too much water; ?? Too much sun. Any ideas?
This is typical of Hibiscus. They flowers won't, usually, last for more than a day. Depending on the type, even less.
Unfortunately, there isn't much that you can do for them. This article will help:

I have two new hibiscus plants in a flowerbed. There have been plenty of buds, but they fall off before they ever bloom.
Thrip insects can cause bud drop. Here is how to treat them:

Tiny black spots where lead meets the stem and on all leaves and in 2 pots of red hibiscus plant that are next to each other.
It could be some sooty mold starting. If you look along the stems in the last photo, you see a pest, or pest residue, probably aphids. Sometimes immature scale can look like aphids. They leave behind a sticky honeydew that invites sooty mold. Here is how to eradicate them:
