We planted eight holly trees a month ago and several of their leaves are turning yellow and dropping. Any suggestions as to why this is happening and what we can do to make them healthy again?
It could be suffering from shock. Increase watering. 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 have a Nellie R Stevens that has developed what looks like small white cups, almost like small popcorn, on some of the trunk and branches. When I removed one, something that looked like blood (dark red or red brown) came out. Can you identify what it might be and how to get rid of it? I cannot seem to be able to id it.
It could be scale or mealybugs, which can be treated with neem oil. These articles should help: https://www.gardeningknowhow.com/plant-problems/pests/scale-bug-how-to-control-plant-scale.htm

On several of our bushes, we have a milky white, almost glue-like, residue mostly on the under leaf or stem.
It sounds like a infestation of Mealybug.
Neem Oil is a good treatment.
Here are a few links of Mealybug and other common issues.

I live in zone 7 and am looking for a hedge/screening plan that will grow quickly for privacy near the road. I also thought of adding grasses such as Feather Reed Grass or Switch grass and Russian Sage mingled in among the Hollies until they grew to form a hedge. thoughts?
Easily grown in organically rich, slightly acidic, moist, well-drained soil, but highly adaptable; avoid heavy, wet soils. You will want to amend your clay soil to have success with this shrub.
Here are some links for you.

Hi There, I have a nelly stevens holly planted across the fence. As you can see in the first pic the main branch is long and have growth at the tip but not in the middle. How do i make it grow dense and wide? Another issue i have is i have some hollys that have bare branches inside but the end has full growth. How do i make them grow dense inside the plant?
Both will be corrected with proper pruning. These are ways that no, or improper pruning affect these shrubs. These two articles will help: https://www.gardeningknowhow.com/ornamental/shrubs/holly/trimming-holly-bushes-how-to-prune-holly-bushes.htm

Thank you BushDoctor for your advice. I will take a look at it.
Hi There, Should i start pruning the holly at the red mark in the pic as a starting point? Thanks
That will be completely fine. It looks like a good start for pruning.
We bought 10 of these a couple of years ago. They are settled in well and are a mass of berries this year. Will the energy be going into the berries rather than the branched/leaves? We would like the tree to grow rapidly for the first few years. Thanks
It's a fast growing tree whether or not it has berries, up to 3 feet a year.
