About soil condition, Nandina shrub prefers rich, well-drained soil but also does well in average, dry to somewhat dry soil. It does not tolerate heavy, wet soils. If you have heavy clay soil, mix in some sand and organic matter to improve drainage. Nandina shrub is tolerant of both acid and alkaline soils.
So, like the other plants, Nandinas need sunlight to grow. They prefer full sun, but can also tolerate partial shade. If they don't get enough sun, they may become leggy and produce fewer flowers. So, make sure to give them a sunny spot in your garden!

Pruning is an important part of keeping your nandina shrub healthy and looking its best. You'll need to prune annually to remove any dead or dying branches. You can also prune to shape the shrub or to control its size. When pruning, be sure to make clean cuts at a 45-degree angle.
Propagation is best done by taking semi-ripe cuttings in late summer or early autumn. Softwood cuttings can be taken in late spring. The cuttings should be about 10cm (4in) long and have a heel if possible. Use a sharp knife or secateurs, and make a clean cut just below a leaf joint. Remove the lower leaves, then insert the cutting into moist, sandy soil in a propagator or place it in a plastic bag. Keep at a temperature of 18-21°C (64-70°F).
Usually, the plant growth rate is considered to be fast when young, but will eventually begin to slow with age. When planting, be sure to give the shrub room to grow since it can reach up to 6 feet tall and wide. Nandina shrubs are known to be heat and drought tolerant once they are established.
