My barberry bush isn't doing well. Any fertilizer I could use? It seems to have moss growing on it.
You mention that it seems to have moss on it but given the distance the photo was taken from the tree I am having difficulty seeing it. You may send a close-up photo if you wish. What you see could possibly be moss or lichen. More information on moss & lichen can be found here:

Your barberry does look a little tall and scraggly. Barberry bushes do respond well to rejuvenation pruning so that it something you may want to consider. More information on rejuvenation pruning can be found here:

As for fertilizer, you can apply an all-purpose, slow-acting granular fertilizer.

We had our large barberry pruned in winter. The man who pruned it took a lot off, probably half of the bush, and now it looks as though it is dying. It has berries but some leaves are brown. Will it be ok?
You had e-mailed me directly and asked if all barberries were edible. It appears as though they are as I found nothing in my research that indicated otherwise.
I wouldn't worry too much - barberry is one of those shrubs that is said to be able to withstand a severe pruning and which will come back bushier and denser because of it. In the meantime the best thing you can do is give the barberry bush the care that it needs, which is outlined in the following article:

We want the burgundy color and really like barberry, but cannot have the thorns.
Probably your best bet would be the Japanese Barberrry (Berberis thunbergii "Thornless") which is nearly thornless.

Why does your site promote the invasive Japanese barberry? Shame on you! Identify invasive species.
It is true that Japanese barberry is invasive in some parts of the country but in other parts it is a perfectly suitable and well behaved plant. While it may be a problem plant in your area, other people may live in an area where it is ok and they need information on how to grow it. It is always best before you plant any new plant in your garden to check to see if it is invasive in your area because invasiveness changes from location to location.
That being said, I have requested that the editors add a note to the plant stating that it is invasive in some areas.
I just read an article about the 10 plants you don't want to have and it said the Japanese Barberry is one. It says that it harbors the black legged tick that carries Lyme disease. I have these in my yard. Have you heard that?
This information has been out for a few years.
The Japanese Barberry shrub is actually listed as invasive in many parts of the country.

I have a beautiful barberry bush and I would like another one but can't find the same one. So I would like to grow one on my own. Do I cut a sapling or do they begin with a seed?
Yes, you can propagate a Barberry shrub.
Here is a link that provides information.

I have three bushes, which I believe are barberry in my front yard. One is like twice as tall as the others. If I cut it back to the ground, will it regrow?
I wouldn't take off more than a third of the plant as this can make it more susceptible to pest or disease issues. For more info on caring for barberry, this article will help: https://www.gardeningknowhow.com/ornamental/shrubs/barberry/barberry-shrub-care-tips.htm
