Goji berries are promoted as an ultimate health food because they contain more antioxidants than any other single natural source. However, they are also relatively expensive--when you can find them. Many home gardeners are electing to grow their own goji berry plants to ensure that they have a constant supply of fresh-picked berries. Fortunately, growing goji plants from seeds is not terribly difficult.
Remove the seeds from several ripe goji berries. The seeds are small, not much larger than tomato seeds. Wash and dry the seeds and seal them in a freezer bag.
Place the seeds in your freezer for 30 days. This mimics the cold Himalayan winter for which the seeds would naturally be subjected.
Remove the seeds from the freezer and allow them to warm on a countertop for 24 hours.
Fill a small tray with water and allow the seeds to soak for seven to 10 days. Replace the water every two days to keep it fresh. Watch for the seeds to begin to sprout.
Fill growing pots with a 50/50 mixture of sand and an organic compost. Make sure the growing pits have a drain hole. Plant a single sprouted goji berry seed in each growing pot, gently planting them approximately 1/2 inch deep, covering them with the sand and compost mix.
Water gently and keep the soil damp, but definitely not soggy. Allow the soil to dry slightly between watering, but do not let it become completely dry. When the seeds sprout, allow them to receive eight hours of sunlight per day.
Transplant your goji plants to a sunny and well-drained place in your garden in the spring when they are approximately 4 inches tall. Mix compost into the garden soil in a 50/50 mix when planting, but do not fertilize your goji plants. Keep the ground lightly moist, but do not saturate the soil as goji plants are used to harsh conditions.
