Choose a spot that will protect the bush from strong winds. Nandina requires full sun, but prefers afternoon shade in extremely hot conditions. The color of the foliage depends on the amount of sun the plant receives. If provided with significant sunlight, the leaves will grow more vibrant in color than if planted in shade. Nandina tolerates most soil types including sandy, loam or clay soil. For best results, provide moist, well-drained, fertile soil. Amend soil with compost to provide additional nutrients to the plant. Add 3 inches of mulch around the plant to prevent weed growth. Nandina can withstand temperatures as low as -10 degrees Fahrenheit, but mulching may help protect the shrub during cold winter weather.
