This hardy, deciduous shrub has increased in popularity in recent years. It yields a plentiful supply of nutritious red berries, which can be eaten fresh, cooked or dried.
Goji berries are not generally difficult to grow;
Plant in free-draining soil that has been enriched with well-rotted garden compost or manure. Space plants at least 2m (6½ft) apart. Feed in spring with a general purpose fertiliser such as Growmore at 70g per sq m (2oz per sq yd).
Choose a container with good drainage holes, and use a John Innes No 2 potting compost with added grit or sharp sand. Apply a liquid fertiliser (such as tomato feed) fortnightly during the growing season.
Plants begin to fruit after two-to-three years. Harvest berries from late summer until the first frosts. Only fully ripe fruit are edible. Fruit can turn black when handled so consider harvesting by shaking the berries gently from the plant onto a sheet placed beneath.
For maximum fruiting, it is best to train plants against a wall or fence, tying the lax stems onto wires. Wear gloves for protection against spines.
Flowers and fruit are formed on the stems that grew in the previous year, so pruning aims to encourage the production of this wood.
Sow seeds indoors in spring, covering with a very fine layer of compost; germination is best at 18-20°C. Take softwood or semi-ripe cuttings in summer, hardwood cuttings in winter; layer plants in autumn or lift and replant suckers in late winter.
Give seedlings and rooted cuttings protection in their first winter and plant out the following spring.
There is only one form of this plant and it is now widely available. To find a supplier, use the RHS Plant Finder.
Aphids can be a problem and netting may be necessary to protect fruit from birds.
Suckers are produced freely and may need to be controlled.
