The rosy glow barberry (Berberis thunbergii) is a low-maintenance flowering shrub that grows up to 5 feet tall and wide. The shrub has colorful pink and purple leaves that turn a deep red color in the fall. The rosy glow barberry blooms with yellow flowers in the spring and grows in a dense, mounding form. The shrub produces bright-red berries in the fall that stay on the shrub throughout the winter. The rosy glow grows best in USDA hardiness zones 4 through 7, where winters are colder and minimum temperatures go as low as minus 25 degrees Fahrenheit.
Plant your rosy glow shrub in the spring, after the last chance of frost has passed. Select a planting site for your rosy glow barberry that is in full to partial sunlight and has well-draining soil.
Dig a planting hole for your rosy glow barberry that is the same depth as and 1 1/2 times the width of the nursery container. Loosen the soil around the bottom and sides of the planting hole. Mix into the displaced soil some organic compost, if the soil is extremely nutrient-poor.
Remove the rosy glow barberry from its nursery container and set the root ball into the hole. Back fill the hole with the displaced soil, then water the plant generously to soak the soil down to the roots.
Water your rosy glow barberry in the spring and summer only during times of drought or prolonged dry spells. The rosy glow shrub will tolerate some drought, however.
Trim your rosy glow shrub in late winter or early spring to remove any broken, diseased or crowded growth. Prune to shape the shrubs if you're growing them as a low hedge.
