My sky pencils have small (5 - 7") growths coming directly from the ground about 6 -8" from the main plant. Is it OK to let them continue to grow? Will they eventually become available as a new plant for me to transplant elsewhere?
You can try digging these root suckers up. Spring is the best time to propagate using suckers, as this is when plants are coming into active growth and the severed suckers will establish themselves quickly.
I would really like to plant Skypencil hollies as a privacy screen along the back edge of my property line but I recently discovered that there is an old gas line running right thru that area. The gas line runs back to a church behind my house. Are the root systems that invasive?
These are not known to be the least bit invasive. With this being said, it is still recommended to keep 5 feet away from anything important. Still, there are not many dangers from this root system.
This holly was planted by the designer. It was put in a hear ago. I am noticing that several of the little leaves are turning brown. I looked under the weed barrier and it is pretty wet. It does receive water from two sprinklers, but the nursery knew that. I have now read about the plant and I am told that it does not need a lot of water. Should this holly be moved or placed into a container? Or, will it survive the moisture?
They definitely need to be moved. This will be too much moisture for them. This sounds like the reason that they are suffering, and moving them will be the best option.
Our shrubs are in their fourth summer. Very suddenly one of our sky pencil Japanese holly shrubs has died. The other one planted a few feet away looks fine. Do they have a short life span? I cut back the height about twice a year to keep them about four feet tall. We live in Louisiana.
This plant has some vulnerabilities, including root rot from poorly drained soil and/or overwatering, and fungal disease.
Your frequent pruning is opening wounds that can become contaminated from pruning tools or infection from airborne fungal spores. Disinfect your shears with Lysol spray or 10% bleach solution before each pruning of the remaining plant. Spray with neem oil or a biological fungicide immediately after pruning.
The soil and drainage may be different in the two locations, or if not, the remaining plant may be vulnerable to the same fate if the soil is in fact heavy clay and poorly drained.
my holly is turning brown what is wrong with it and what can i do for it to make it healthy?
This is, most usually, caused by fungal damage. I would apply wettable sulfur dolomitic lime to the area to correct the issue. It could be all the way until spring before it recovers correctly, but this usually takes care of it.

I want to grow Sky Pencil Holly in a planter.
Yes, you can grow in a container. I would use a pot size in the 20 inch range. A half whiskey barrel will work nicely also.
There is no brown or yellow, but the do look “milky” compared to the others.
This can be expected for new transplants. This is especially true for summer transplants. This is not recommended.
It is best to do transplants in Spring to avoid excessive stress, since transplanting is already stressful for the shrub.
Just keeping good care will be the only treatment, until it takes to its spot. This article will help you to care for them: https://www.gardeningknowhow.com/ornamental/shrubs/holly/care-of-sky-pencil-holly.htm
