Plant goji berries in a south-facing area of your garden that is not covered by shade from trees or buildings.
Till the soil in your chosen area and mix in compost, manure or another organic material at a rate of two parts soil to one part organics. This increases the nutrients in your soil and drainage, preventing root damage from standing water.
Place a goji seed on the soil and press down with your thumb until the seed is covered by about 1/2 inch of soil. Do not bury the small seeds any deeper than this.
Heavily water the soil so that the top six inches of soil are moist. Use a watering can or hose with a light spray nozzle instead of a full pressure sprayer.
Keep the seeds well-watered, and do not let the soil dry out between waterings. Maintain this heavy watering for the first six months as the wolfberry bush establishes itself.
Mulch the area at the base of the wolfberry plant with wood chips, pine needles or another organic material.
Reduce watering after the plants become established, generally after the first six months. Once the shrubs begin to bloom, water only when the top two to three inches of soil have dried out. Do not water if it rains, as over-watering can damage roots.
