The goji plant has gained a lot of notoriety in Europe and North America in recent years as people have become aware of its impressive medicinal properties. Originating from China and Tibet, the goji plant has been used for centuries in those regions to treat everything from high blood pressure to diabetes. Western science has recently concluded that goji or Lycium barbarum is indeed a powerful antioxidant and also has anti-tumor and immune stimulative properties. Goji derives from the Chinese name "Gou Qi Zi" and is also known as matrimony vine, Chinese wolfberry and Chinese boxthorn.
Plant your goji in direct sun or partial shade. The soil must drain well as these plants will not tolerate soggy, saturated conditions. If wet ground is an issue, grow your goji in a container as a nice ornamental plant for the patio or deck. Choose a container that matches the size of your plant and transplant it as it grows. Blend three parts potting soil, one part vermiculite and one part sand to make your container mix.
Dig aged compost or manure into the soil before planting goji in the garden. The organics will enrich the soil with nutrients and give your plant a good start.
Water your goji plant heavily once a week. A good 12- to 20-minute soak weekly is more effective than small amounts of water given daily.
Prune goji plants in spring to remove deadwood and shape. Keep shaping to a minimum as it will reduce the berry yield. Allow container grown plants to reach 3 to 4 feet in height so that they produce a decent berry crop.
Fertilize in spring with a low-nitrogen, high-phosphorus organic product such as bone meal. High-nitrogen fertilizers will encourage foliage growth at the expense of the fruit.
Examine your plants occasionally for signs of disease or insect infestation. Goji plants are generally very healthy but some growers have run into problems with gall mites. An application of horticultural oil, neem oil, mineral oil or an insecticidal soap will usually be effective against most insects.
