Goji is a shrubby plant that can, in time, grow 1-3m (3-10′) tall. Growers space Goji plants 60cm (24″) apart in rows that are 2m (6′) apart. Spaced this way, 15 plants in a 30 foot row can produce up to 100 lbs of berries in a year. Goji is self pollinating, so even a single plant will produce fruit.
Goji is unusual in that it prefers relatively infertile, slightly alkaline soil with a pH range of 6.8 to 8.1. Goji reacts poorly to fertilizer and manure, so if growing in a large container, use simple top soil with some perlite mixed in for drainage. Avoid peat-based soils.
If severe winter weather is expected, it is wise to mulch around the bases of Goji plants, or move container plants into a cool but frost free area such as a garage.
