The goji berry plant is a 10- to 12-foot-high shrub that produces a nutrient-rich berry. The plant is native to Tibet and the Himalayan mountain range and is hardy in USDA growing zones 5 through 9. Goji plants can withstand temperatures down to -15 degrees F and as high as 100 degrees F. The berries are the size of a raisin and will ripen in late summer. The goji plant does not grow well in a formal garden setting and prefers to grow on its own or as a hedge.
Purchase viable goji berry seeds to guarantee they were processed correctly for germination. Extracting the seeds from sun dried berries may not properly germinate.
Fill a large planting container with standard potting soil mixed with organic compost. Place the seeds ½ inch into the soil. Replace the soil in container grown plants on a yearly basis to provide needed nutrients for the plants.
Plant goji berries directly into ground soil in USDA hardy growing areas. The soil must be well draining and mixed generously with organic compost for nutrients.
Plant or place the goji plant in a location that offers southern exposure sunlight. Do not plant near roadways that are dusty as this will expose the plant to pollution from dust and vehicle exhaust. The plants should receive 8 hours of direct sunlight per day. Supply indoor growing plants with supplemental lighting if needed.
Water newly planted goji seeds to keep the soil moist until germination. Allow the soil to dry slightly before watering again once the berry sprouts are visible. Do not saturate the soil or water the leaves of the plant.
Prune the goji plant once it measures larger than 8 to 10 feet in height to increase berry quality and production.
Work organic compost into the soil around the plants on a yearly basis to provide natural fertilizer nutrients.
