Site Selection
-
Crimson Pygmy barberries are hardy between U.S. Department of Agriculture plant hardiness zones 5 and 8. Plant them in full sun or partial shade, although the foliage is a better color when planted in full sun. They tolerate wet or dry conditions and sandy, loam or clay soils. They are often referred to as a "parking lot" shrub because they can take a lot of abuse and neglect.
Uses
-
Crimson Pygmy barberry grow 2 feet high and 3 feet wide, making them a good choice in mixed beds or as a specimen plant. Place them in front of larger shrubs for a layered look in a shrub border. Mix them with shrubs of similar heights, such as dwarf Japanese spirea. Plant low-lying ground covers or perennials around their feet.

Care
-
Although barberries tolerate poor soils, they'll grow better if you amend the soil with compost or manure before planting them. While they aren't picky about conditions, companion plants may need improved soil. Water young plants frequently during the first summer as they develop strong roots and become established. Water mature plants every week or two during dry weather. Fertilize Crimson Pygmy barberries in spring with 1/2 cup of 10-10-10 fertilizer per plant.
Pruning
-
Prune barberries back in late winter or after flowering to remove dead branches or straggly, awkward limbs. A light pruning annually is usually sufficient but if the plants are overgrown, cut them back to 12 inches above the soil. They'll regrow quickly and have a lush, compact form. Crimson Pygmy barberries have thorns, so wear garden gloves when pruning or caring for them.
