The golden barberry plant is characterized by its bright yellow foliage. To care for this plant, follow a simple process using well-drained soil, mulch, pruning shears, water and fertilizer.
Choose a good location
Plant the golden barberry in full or partial sun. Pale yellow or lime green foliage signifies a lack of sunlight. Use well-drained soil.
Mulch the plant
Add 2 inches of mulch to the plant twice a year. This enriches and moistens the soil.
Prune the plant
Remove damaged and diseased limbs as often as necessary. Prune away old woody branches in late winter or early spring. If needed, cut the bush down to just above ground level. Keep the bush at your desired shape by trimming its limbs every eight weeks. Cut branches 1/4 inch above the nearest bud.
Water the plant
Regularly water the plant so that the soil stays moist. Water it immediately if the soil beneath the top layer is dry.
Fertilize the plant
Fertilize the bush with an all-purpose fertilizer that is either water-soluble or granular. The fertilizer needs to have a nitrogen-phosphorus-potassium ratio of 6-12-12 or 10-10-10. Apply it in early spring before new growth. Continue the applications once a week throughout the season.
