    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.

    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.

    Here is a link to refresh you on care requirements.

    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

    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.

    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.
