III. Planting, Caring for Goji Berries
1. Planting Methods
a. From Seeds
Starting goji berries from seeds is a rewarding yet more time-consuming method.
- Step 1 – Obtain fresh goji berry seeds
You can either purchase seeds from a reputable nursery or extract them from dried goji berries. If using dried berries, soak them in water for 24 hours to soften the pulp, then gently remove the seeds. - Step 2 – Stratify the seeds
Goji berry seeds require a period of cold treatment, known as stratification, to break dormancy and promote germination. Place the seeds in a moistened growing medium, such as peat moss or vermiculite, inside a sealed plastic bag. Store the bag in the refrigerator at around 40°F (4°C) for 4 to 8 weeks. - Step 3 – Sow the seeds
After stratification, sow the seeds 1/4 inch deep in seed trays or small pots filled with a well-draining seed-starting mix. Keep the soil consistently moist and provide ample sunlight or grow lights. Germination typically takes 1 to 4 weeks. - Step 4 – Transplant seedlings
Once seedlings have developed 2 to 3 sets of true leaves, carefully transplant them into larger pots or directly into your prepared garden bed.
b. Cuttings
Propagating goji berries from cuttings is a faster method to establish plants and ensures your new plants will be true to the parent variety.
- Step 1 – Take cuttings
In late spring or early summer, use clean, sharp pruning shears to take 4 to 6-inch cuttings from healthy, disease-free goji berry plants. Choose semi-hardwood stems with at least two sets of leaves. - Step 2 – Prepare cuttings
Remove the lower leaves from each cutting, leaving only the top 2 to 3 sets. Dip the cut end of each stem in rooting hormone to encourage root growth. - Step 3 – Plant cuttings
Insert the cuttings into a well-draining growing medium, such as a mix of perlite and peat moss. Plant them deep enough to support the stem, ensuring that at least one set of leaves remains above the soil surface. - Step 4 – Provide proper care
Keep the cuttings in a sheltered location with indirect sunlight and maintain consistent moisture. Rooting should occur within 4 to 6 weeks. Once the cuttings have developed a strong root system, transplant them into your prepared garden bed.
c. Container-Grown Plants:
Purchasing container-grown goji berry plants from nurseries is the quickest way to start your goji berry patch. These plants are often ready to be transplanted directly into your garden.
- Step 1 – Purchase healthy plants
Obtain healthy, disease-free goji berry plants from a reputable nursery. Choose plants that are well-rooted and have a strong, vigorous growth habit. - Step 2 – Plant at the right time
The best time to plant goji berries is in the spring or fall, when temperatures are cooler and the plants are dormant or semi-dormant. - Step 3 – Dig planting holes
Dig holes in your prepared garden bed that are slightly larger and deeper than the root ball of your container-grown plants. - Step 4 – Plant goji berries
Carefully remove the plants from their containers, gently loosening any tangled roots. Place the plants in the holes, ensuring the base of the stem is level with the soil surface. Fill in the holes with soil, firming it gently around the roots. Water thoroughly to settle the soil and eliminate air pockets. - Step 5 – Space plants appropriately
Follow the spacing guidelines mentioned in the section above to ensure proper air circulation and light penetration for your goji berry plants.
- Timing: The best time to plant goji berries is in the spring after the last frost or in the fall, well before the first frost, to give plants ample time to establish.

Integrated Pest Management (IPM)
Consider adopting an Integrated Pest Management approach that combines cultural, biological, and chemical methods to control pests in a way that minimizes risks to human health, beneficial insects, and the environment. IPM emphasizes the use of non-chemical methods first and reserves pesticides as a last resort when other strategies have failed and pest populations have reached a damaging level.
IV. Harvesting Goji Berries: Timing, Technique, and Preservation
1. When to Harvest
- Plant maturity: Goji berry plants typically take 1 to 2 years to start producing fruit after planting. Once mature, they will produce fruit annually.
- Season: Goji berries usually ripen from late summer to early fall, depending on your climate and variety. The exact timing may vary, so it’s essential to monitor your plants closely during this period.
- Ripeness: Goji berries are ripe when they turn a bright, deep red color and are plump and slightly soft to the touch. It’s essential to harvest the berries at the peak of ripeness, as they won’t continue to ripen after being picked.
- Frequency: Goji berries don’t all ripen simultaneously, so you’ll need to harvest them every few days or up to once a week during the peak season. Regular harvesting encourages the plant to produce more fruit.
2. Harvesting Methods
Hand Picking
This method ensures minimal damage to the plant and allows for selective harvesting of ripe berries. It’s best used when you have the time to carefully harvest and when you’re aiming for the highest quality of fruit.
- Gentle Touch: Hand picking is the preferred method for harvesting goji berries. It allows for the careful selection of ripe berries, minimizing damage to the delicate fruit and the plant itself. Gently grasp the berry or the stem close to the berry between your fingers and lightly twist or pull to detach it from the plant.
- Stem Snipping: In instances where berries are tightly clustered or difficult to reach without risking harm to the plant, utilize clean, sharp scissors or pruning shears. Snip the stem just above the berry cluster to remove it. This technique helps in avoiding any unnecessary strain on the plant and ensures a clean harvest.
Shaking Technique
Ideal for harvesting large quantities of berries quickly. However, it might result in a mix of ripe and slightly underripe berries and requires a gentle approach to avoid harming the plant.
- Tarp Collection: For larger yields, consider gently shaking the branches over a clean tarp or sheet laid out beneath the plant. This method can facilitate the collection of ripe berries that are ready to fall. It’s a faster technique but requires a careful approach to prevent damage to the plant and loss of unripe berries.
- Selective Shaking: Aim to shake branches that show a majority of ripe berries. It’s important to perform this method gently to avoid dislodging berries that are not yet ready to harvest and to prevent potential damage to the plant structure.
Harvesting Schedule
- Regular Inspection: Goji berries ripen over time, not all at once, necessitating regular checks on the plants throughout the harvest season. By inspecting the plants every few days and picking ripe berries, you can encourage further fruit production.
- Optimal Timing: If possible, harvest goji berries in the morning. The cooler temperatures of the morning result in firmer berries, reducing the risk of damage during the harvesting process.
