Amur barberry grows in full sun or partial shade. It prefers warm, moist loam with some light shade. Yet it also grows in thin, dry, shallow soil. It accepts sandy soil, loam, and even heavy clay. Poor soil does not rule out planting it. Suitable soil ranges from mildly acid to mildly alkaline. It tolerates dry or moist ground and exposure to sea winds. Chicago lists USDA hardiness zones 6–9. Plants For A Future gives UK zone 6 and reports frost hardiness.

Gardeners can use this shrub for screens and hedges. It suits woodland gardens and shaded woodland edges. It takes trimming well, allowing formal or loose hedge shapes. Dense hedges can form a barrier that is hard to cross. Plants regrow from the base after hard pruning. Seed offers one way to raise new plants. Sow ripe seed promptly in a cold frame. Stored seed may need a cold period before germination. Seedlings can suffer damping off, so good airflow matters.

The fruit has a recorded food use when cooked into preserves. Plants For A Future also lists leaves as edible. It gives no details about how to prepare them. The same source reports no known hazards. This does not establish safety for people or pets. It records traditional root use for rheumatic complaints. It also reports no weed potential for this species.
