Since goji berries have come into fashion, they have gotten quite expensive. It's no wonder that many health-conscious gardeners are now asking how to grow a goji-berry bush in their own backyard. These nutritious berry bushes thrive in USDA growing zones 7 and above. And once established, goji-berry bushes are quite hardy. They can grow in any type of soil, are drought- and frost-resistant and seem to thrive on neglect.
Use a shovel to dig a hole that is 2 feet deep and twice as wide as the container that your goji-berry bush is currently in. Mix half of the excavated soil with an equal amount of aged compost. Back fill the soil and tamp it down with your feet.
Water the soil so that it is moist to a depth of 4 inches.
Spread a 3-inch layer of leaf-mold mulch around the base of the plant, but keep it at least 4 inches away from the stem of the bush on all sides.
Keep your goji bush's soil moist with regular watering until it establishes itself in 2 to 3 weeks. After it is established, cut watering back to once every 10 to 14 days. Once the goji berry is one year old it is quite drought hardy and will only needed to be watered occasionally in case of drought.
Prune the goji-berry bush in early spring when it gets larger than 8 to 10 feet around and when the vines spread more than 12 feet from the center. This will not only make them more attractive, but increase goji berry production.
