I need to prune my barberry bushes and it is hot. Can I prune them now?
If you need to remove dead wood you can do this any time.
To shape the plant wait until dormant in the winter.

They were planted about a month ago.
New plantings need daily water for the first 2 weeks, even twice a day if the temperatures are above 85 degrees.
Then you can cut back a bit. You need to be very vigil for new plantings this time of the year.
Adding 2 to 3 inches of hardwood mulch will help with moisture retention.

Barberry bushes look as if they are drying up and losing their foliage. I have had 3 barberry bushes for years, all of a sudden they are losing their leaves and look as if they are drying up. It has been very hot the last few weeks. They are on the south side of my home and get full sun. What can or should I do to get them healthy again?
You may need to water to help them through the hot and dry summer days.
2 to 3 inches of hardwood mulch will help with moisture retention.
Watch for insects and treat with Neem Oil if you find any.
Here are a few links for you.

My orange rocket barberry has lost most of its leaves. It hasn't grown in the 8 months I've had it. I live in northern Arizona (Prescott). The branches are still green on the inside but all the leaves have dried up and fallen off. I know it's not dead.
Adequate watering is important for a new planting.
I would trim away the dead material and increase watering.
I also may recommend a soil test, since you indicate the plant did not grow much.

Went to buy a barberry shrub at the garden shop and was told they are forbidden in New York state. Can you help me out?
Japanese Barberry specifically, is on the list of invasive plants that cannot be sold or planted in the state of New York. This is due to new legislation passed by the New York State Department of Conservation. The complete list of prohibited plants can be found on the New York State Department of Environmental Conservation's site: http://www.dec.ny.gov/regulations/93848.html
There are other varieties of Barberry, however, which are NOT invasive prohibited species, and this article may help you choose one of those: https://www.gardeningknowhow.com/ornamental/shrubs/barberry/barberry-shrub-care-tips.htm
We bought two gorgeous barberries to go on either side of our front door. Because we don't plan to stay in our current home for long, we put them in pots rather than the ground. We've had some very hot weather and no rain for about a week (temps over 85) and the bushes were in full sun. I was watering them about once a day in the evening, but they have started to struggle. The leaves are curling up, and a lot of the leaves around the base of the plant are dead. I have been guilty of over watering plants before, and I'm not sure if I've over watered or under watered. They've only been planted about a week. They looked great until about two days ago. What can I do to bring them back?
More water!
New plants in containers will need daily watering, and most likely twice a day during hot weather.
Keep the soil evenly moist, but never soggy. Make sure the pot has adequate drainage holes.

We have a couple barberry bushes, probably intermediate type, that have grown too big for the place where they are planted. There is a good amount of dead undergrowth. The base is established and gnarly. I would like to cut it back to the base and get all new growth for next year so that we can keep it both healthy and right-sized. Can it be cut back to the base? If so, when? In early winter? Thank you in advance. Linda S Hoffman
Dead growth can be removed in the summer.
Regular pruning should be done during winter or fall.
Barberry plants do well with a rejuvenation prune, so you can cut it back quite severely.
I personally cut back an 'ugly' Barberry last fall and it now will need a shaping prune this fall.
