I have Holly shrubs that are dying from the center out. I had someone tell me they have bugs and also need to be fertized. What would you recommend me using as an insecticide spray and fertilizer?

As for pesticide, I would recommend neem oil. It works on most insect pests and is safe to use. As a bonus, it's also an effective fungicide, which should help with any fungal issues caused as a result of the insects.

In regards to fertilizing holly, fertilize once a year (preferably in spring) with a balanced fertilizer. There is a fertilizer called Holly-Tone that is specifically made for holly and is very good.
I live in Dallas, TX. I transplanted several holly bushes (planted at different location) a week ago (July 9). They are turning brown and appear to be dying. I know you suggest doing this in the spring. They were transplanted properly and have been watered daily. Any suggestions on helping these bushes? HELP!
Did you prune when they were transplanted? If not, try pruning the plants by up to 1/3. Also, increase watering. This time of year, they will need significant amounts of water due to the heat so you may need to water 2 times a day. Water deeply every time you water them. Also try adding some root booster fertilizer to the soil. Many nurseries now sell this mix of fertilizer.
I also live in the Dallas area. Plants are stressed to the max right now with all the heat and no rain. Any transplants now are going to struggle. Simply surface watering will not do do it - maybe you are doing this already, but if not, recommend you water deeply by laying a trickling hose directly at the base of each plant every other day. Leave it running for ten or fifteen minutes and then move to the next plant. You want to get those roots moving downward to establish themselves. If the plants are very small, go ten minutes every day until they start perking up (hopefully).
How much can I cut off a holly bush?
Do you just want it shorter or what is the objective? I inherited a holly with this house and it was a big bush. It looked kind of wild and lopsided so I trimmed off all lower branches and turned it into a standard (small tree). I think I did this early Spring or late Fall. It didn't bother it a bit. Did the same thing for a girlfriend last Fall and her's is doing well, too.
One of my Holly bushes has white spots on the leaves and stems. The leaves below are dying and above are still green, but still have white spots. We have another Holly bush on the other side of our front door, same exposure etc. , and it is in perfect condition. What can be done?
Sounds like a classic case of scale, treatable with horticultural oil. This article should also be of help:
Our holly bushes were healthy at our new house (we moved in about a year ago) and did very well through the fall and winter. This spring some new growth was evident, but suddenly all the green leaves started falling off both of the bushes. The bushes are now bare (July) and it looks as if the branches are browning out and dying. Should I cut the bushes way back, or are they too far gone?
Are they getting sufficient water? There is so much hot weather all across the country and many plants, even those that are established, require extra water this year. Just a normal sprinkler system is not getting the roots where the water is needed. Holly are pretty tough - I cut mine way back (because I didn't want them) and they keep popping back. I would trim them back about half, make sure they are getting sufficient water (lay hose next to plant with a tiny trickle and leave for ten minutes, if you are experiencing very dry weather). This should be done twice a week. YOu also could get a drip hose. I poke my fingers into soil to see how dry things are..........and water accordingly.
Are the berries on the holly bush poisonous?
They are poisonous, but not typically deadly. They will cause vomiting and nausea.
The leaves on my holly bushes have been turning yellow and dropping off. The bushes themselves are growing new leaves and even producing berries; however, they are very sparse. At first I thought it might have been the harsh winter, so I gave them a good fertilization early in the season. They continue to drop their leaves (not just a few, bunches and bunches), and I just don't want to overlook something and lose them altogether. Any insights would be greatly appreciated!
