In this blog post, we’ll walk you through the steps on how to grow goji from seed so that you can get back to using it in no time! So grab your tools, and let’s get started!

Understanding the Goji Berry Plant

The goji berry plant (Lycium barbarum and Lycium chinense) is a deciduous shrub that belongs to the nightshade family, which also includes tomatoes and peppers. Native to Asia, particularly China and the Himalayan regions, goji plants thrive in diverse climates and are renowned for their adaptability. These hardy plants can grow up to 6–10 feet tall and are characterized by their slender branches, delicate purple flowers, and vibrant red berries. Goji berries are packed with vitamins, antioxidants, and amino acids, making them a sought-after superfood.

Known for their resilience, goji plants can tolerate a wide range of temperatures, making them suitable for many home gardeners who are eager to cultivate these nutritious fruits. Understanding their basic requirements will set the foundation for a thriving plant.

When to Plant Goji Seeds

The best time to plant goji seeds is in early spring, after the danger of frost has passed. Goji plants thrive in warm temperatures, so waiting until the soil has warmed up ensures better germination and growth. If starting seeds indoors, you can begin planting 6–8 weeks before the last expected frost. This gives the seedlings enough time to develop before being transplanted outdoors. Proper timing is essential to give your goji plants a head start and ensure a healthy growing season.

Tools and Supplies You’ll Need

To successfully plant goji seeds, you’ll need a few essential tools and supplies. Start with high-quality goji seeds from a trusted source, as this ensures better germination rates. You’ll also need seed trays or small pots filled with a well-draining seed-starting mix. A spray bottle for gentle watering, plastic wrap or a humidity dome to maintain moisture, and a sunny windowsill or grow light for consistent light are critical for indoor germination. For outdoor planting, have a garden trowel, compost or organic fertilizer for enriching the soil, and mulch to help retain moisture. Proper preparation with these tools will set you up for a successful growing season.

10 Methods How to Grow Goji from Seed

1. Select High-Quality Goji Berries for Seed Extraction

The journey of growing goji berries (Lycium barbarum or Lycium chinense) from seed begins with selecting ripe, healthy fruit. If you have access to fresh goji berries, choose plump, fully red or orange-red berries, as these contain mature seeds ready for germination. Avoid berries that are underripe, shriveled, or moldy, since seeds inside may be immature or nonviable. If you’re purchasing dried berries, check if they are certified seed-grade or specifically meant for planting, as many dried berries on the market are processed and unsuitable for seed saving. Starting with quality fruit ensures you have viable seeds to work with.

2. Extract Seeds from the Berries Carefully

Once you have ripe berries, you’ll need to extract the seeds from the pulp. Place the berries in a bowl and crush them gently to release the seeds and pulp. Add water and stir to help separate seeds from fruit debris. The seeds typically sink while pulp floats, allowing you to decant or pour off the lighter material. Rinse the seeds several times in clean water to remove residual sugars and pulp, which can promote mold or fungal growth if left on the seed surface. This thorough cleaning helps prepare the seeds for healthy germination.

3. Dry the Seeds Properly Before Storage or Planting

After cleaning, spread the goji seeds in a single layer on a paper towel or mesh screen in a warm, dry place away from direct sunlight. Allow them to dry for several days until they are no longer sticky or moist. Proper drying prevents mold during storage and planting. If you plan to plant immediately, drying for 1–2 days is usually sufficient. For longer storage, ensure seeds are completely dry and store them in a breathable container like a paper envelope, labeled with date and variety. Properly dried seeds retain viability longer and improve germination rates.

4. Stratify Goji Seeds to Mimic Natural Winter Conditions

Goji seeds benefit from cold stratification to break dormancy and encourage germination. Mimic natural winter conditions by placing the dried seeds in a sealed plastic bag with a small amount of moist peat moss or sand. Refrigerate the bag at about 34–41°F (1–5°C) for 4 to 6 weeks. This chilling period tricks the seed into thinking it has passed winter and is ready to sprout. Stratification is especially important in cooler climates and significantly increases germination percentages. If you live in a warm climate, stratification is still recommended but can sometimes be shortened.

5. Start Seeds Indoors in Early Spring Using a Light, Well-Draining Medium

After stratification, sow goji seeds indoors approximately 8 to 10 weeks before the last frost date. Use seed trays or small pots filled with a light, well-draining seed-starting mix, such as a blend of peat moss, perlite, and vermiculite. Sow the seeds on the surface or just lightly cover them with a thin layer of soil, as they require light for germination. Maintain the soil evenly moist but not waterlogged. Keep the trays in a warm location, ideally around 70–75°F (21–24°C), with good airflow and bright indirect light or supplemental grow lights to encourage healthy seedling growth.

6. Monitor Germination and Thin Seedlings for Best Growth

Goji seeds typically germinate within 10 to 21 days after sowing, although germination times can vary. During this period, keep the soil moist but avoid overwatering, which can cause damping-off disease. Once seedlings develop their first set of true leaves, thin them to prevent overcrowding. Select the strongest and healthiest seedlings to grow on, and remove weaker ones by snipping at the soil line to avoid disturbing roots. Proper thinning ensures each plant has enough light, nutrients, and space to develop into a vigorous, productive shrub.

7. Harden Off Seedlings Gradually Before Outdoor Transplanting

When your goji seedlings reach about 4 to 6 inches tall and after the last frost risk has passed, it’s time to harden them off. Gradually acclimate the young plants to outdoor conditions over 7 to 10 days. Begin by placing them outdoors in a shaded, sheltered location for a few hours, increasing their exposure to sun and wind each day. This gradual hardening reduces transplant shock and prepares the plants for the variable temperatures and sunlight they will encounter in the garden. Without this step, seedlings may become stressed, slowing growth or even dying.

8. Choose a Sunny, Well-Drained Site for Transplanting Goji Plants

Goji berries thrive in full sun and well-drained soil. When transplanting seedlings outdoors, select a location that receives at least 6 to 8 hours of direct sunlight daily. The soil should be loose, sandy to loamy, and slightly acidic to neutral (pH 6.5–7.0). Amend heavy clay soils with compost or sand to improve drainage. Space plants about 3 to 5 feet apart to accommodate their mature size and allow good airflow. Planting in a raised bed or mound can help prevent root rot in wetter climates. The right site ensures healthy growth, better fruit production, and pest resistance.

9. Water Young Plants Regularly but Avoid Overwatering

After transplanting, water your goji plants thoroughly to settle the soil around their roots. Young goji plants require consistent moisture as they establish but avoid waterlogging, which can damage roots and promote fungal diseases. Water deeply once or twice a week, depending on weather conditions and soil type, allowing the top few inches of soil to dry out between watering. Mulching around the base with straw, bark chips, or organic matter helps retain moisture, suppress weeds, and moderate soil temperature. Proper watering habits are crucial to robust plant development and abundant harvests.

10. Be Patient—Goji Plants from Seed May Take 2–3 Years to Fruit

Growing goji berries from seed requires patience, as plants typically take 2 to 3 years to mature and produce fruit. Unlike plants grown from cuttings or nursery transplants, seed-grown plants need this time to develop strong root systems and sturdy branches before flowering and fruiting. During this period, continue to care for your plants by pruning to encourage bushiness, feeding annually with balanced fertilizer, and monitoring for pests and diseases. Once mature, a well-cared-for goji plant can produce berries for many years, rewarding your early patience with nutrient-rich, antioxidant-packed fruit.

Conclusion

Growing goji from seed is a gratifying process that offers the excitement of nurturing a powerful superfood shrub from the very beginning. By selecting ripe berries, carefully extracting and cleaning seeds, stratifying to simulate winter, and providing ideal germination and growing conditions, you set the stage for healthy seedlings and vigorous plants.
