Looking for a few holly trees that do not produce berries.
Any male of any holly species will lack the capacity to produce berries. You have your choice, as long as you are choosing a male of that variety.
Reputable garden centers will sell specimens that are labeled.
4 small Holly bushes have "appeared" in my garden. They are now big enough to transplant as I don't want them to mature in those places. When is the best time to do this? thank you
The best time will be in early Spring, or Autumn. Doing so now will likely result in shock.
Be sure to dig pretty far around, as not getting the roots will leave you with two problems. A failed transplant, and the bush regrowing even more vigorously back in the same spot.

unusual and attractive. If I take a cutting in the autumn, will the resulting tree just have cream leaves?
Certainly you can take a cutting and propagate this sport.

Particularly we are wondering about Holly and Cryptomeria Japonica?
Yes, plants can suffer sunburn, especially if they have water deficit, - not watered adequately.
But that does not appear to be what's going on with the holly. It appears to be the inner canopy leaves and not the outer, exposed leaves that are browned.
Even the Cryptomeria, that is extreme die-back when the surrounding plants look better. Could there be some other factor? not enough water, soil disturbance and root damage, gopher damage, herbicide exposure?
They are close to ten years old, in partial shade. What to do to get them to grow tall?
These are notoriously slow growing. If it is producing plenty of berries, then it is signalling that it is healthy.
Unfortunately, these are doing exactly as they should be, so in order to get a taller shrub, you will have to get a variety that grows taller, faster.

Our standard holly has turned yellow. Its trunk and branches hardly have any leaves, but it has a few berries. Is it pot bound or over/under watered?
It certainly could be rootbound. If it has spent more than a year in container without root pruning, then it may be time to do so, while giving it a fresh batch of compost, or nutrients.
1/4 cup of DOLOMITIC LIME and teaspoon of WETTABLE SULFUR will help to keep away any infections during the year. Use this treatment once, or twice per year.

Hello, my Holly bush planted in a front yard Garden has a 10 inch diameter trunk. How can I replace it without its roots disturbing all the plantings around it? Thank you. Leslie C.
This will be quite a daunting task. These have spreading roots that will likely resprout even more vigorously after removal.
Unfortunately, Hollies are known for being hard to remove, and very aggressive in fighting for survival after. It would be best to have a tree service to assess the situation. This link will help you to find your closest extension service: https://www.gardeningknowhow.com/extension-search
