The powerfully nutritious goji berries are typically only available for purchase in dried form. By growing your own, you'll be able to enjoy the tasty berries freshly harvested! To aid germination, soak seeds overnight in warm water (70 to 85 degrees F). Plant in a very fine potting mix that includes sand, and keep soil moist until seeds sprout. First year’s plants should be kept well watered, but once established, goji berry shrubs can be quite drought tolerant. Goji prefers an alkaline soil that is fairly dry, but will tolerate most soils. The plants will grow into a shrub and should be spaced about 3-5 feet apart. Goji can become invasive in some places.
