During the past two days, one of my holly bushes has decided to become a nudist. The leaves are falling off to the point I can't see the ground for the leaves. The leaves look healthy (no spider mite 'webbing' on the leaves or yellow spots, etc. ). Any idea what may be causing this? I live in Tulsa, OK.
My gut is that it is a water or nutrient issue. Based on your location, I would assume it has been somewhat hot, as it is in much of the country, which tends to cause many trees and shrubs to shed their foliage. Give them extra water to see if this makes any difference.
I have found little white bugs on the underside of my holly leaves. They are round and cottonball-like. Do mealy bugs attack hollies?
It sounds like it might be mealy bugs or scale. These articles will help:

For some unknown reason, all the leaves fell off my holly bushes that have red berries. Why, and what can I do to save them?
It sounds like the plants have a fungus that is causing leaf drop. There are a few that can do this, but they all can be treated with a fungicide. Treat the plants with a fungicide.
If there is not much else in the way of vegetation in the area, it could also be deer. While this is not a plant of choice for them, they will eat it if they have not many other choices and they will strip the plant of its leaves.
I have a holly bush, which almost died over the winter hear in Michigan. I pruned the dead branches off this spring, and it is looking better now, but what kind of fertlizer should I use on it to give it a jump start for surviving the up coming winter?
There is one called Holly-Tone that is specifically made for holly and is very good.
Holly bush has white on leaves. I had a tree taken down, so it was in a lot of shade. Now it gets a lot of sun but these white spots started before that.
Are the spots powdery in nature. If so, it is is powdery mildew and can be treated with neem oil. Here is more info: https://www.gardeningknowhow.com/problems/get-the-cure-for-powdery-mildew.htm https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
In addition, it could be scale or mealybugs, which can also be treated with neem oil. These articles should help: https://www.gardeningknowhow.com/plant-problems/pests/scale-bug-how-to-control-plant-scale.htm

My sister just bought 2 Blue Angel hollies. I asked which was the boy and girl. I have holly, but it stated it on the tag. She did not know what I was talking about. Does a Blue Angel require male and female?
Yes, most holly shrubs do require both male and female plants in order to get berries from them (females). This article will help with telling the two apart: https://www.gardeningknowhow.com/ornamental/shrubs/holly/how-to-tell-the-difference-between-a-male-and-female-holly-bush.htm
I have a holly bush in a pot on the patio and recently I have noticed scaley lumps on the leaves. It is swarming in ants and some of the berries are turning black and drying out. Is there anything I can do to help it, as I really don't want it to die?
