Goji -- superfood from your own garden

Goji berries (Chinese wolfberry, Lycium barbarum) have been among the most sought-after superfoods in the world in recent years. These small red fruits are prized for their exceptionally high content of vitamins, antioxidants and minerals. However, what many people don't realize -- goji can be successfully grown right in a Czech garden. Chinese wolfberry is a surprisingly hardy, frost-resistant shrub that, once established, requires only minimal care.

What is Chinese wolfberry

Chinese wolfberry (Lycium barbarum) is a deciduous shrub from the nightshade family (Solanaceae) -- it is therefore related to tomatoes, peppers and potatoes. It originates from northwestern China, where it has been cultivated for more than 2,000 years as a medicinal plant and basic source of nutrition.

Basic characteristics

• Height: 1.5-3 m (without regular pruning up to 4 m)
• Growth: Long, drooping branches form an arched, slightly irregular shrub shape
• Flowers: Small, purple to light lavender, blooms from June to September
• Fruits: Red to orange-red berries 1-2 cm long, ripening from August to October
• Frost resistance: Very high -- tolerates frosts down to -25 °C, overwinters without problems in all regions of the Czech Republic

Nutritional value of goji berries

Goji berries are among the most nutrient-rich fruits ever. They contain:

• Vitamin C in higher concentration than oranges
• Vitamin A and beta-carotene
• Iron, zinc and selenium
• 18 amino acids, including all 8 essential ones
• Antioxidants, especially zeaxanthin beneficial for eye health
• Polysaccharides with proven immune-stimulating effects

Planting and location

Ideal conditions

Wolfberry is remarkably adaptable, but grows best under these conditions:

• Light: Full sun, at least 6 hours daily. In shade, the shrub produces significantly fewer fruits.
• Soil: Well-draining, slightly alkaline (pH 6.5-8.0). It tolerates poor and stony soils, the key is to prevent permanent waterlogging of the roots.
• Location: It appreciates warmer, sheltered locations, but grows without problems even in cooler areas.

When to plant

The ideal planting time is spring (April-May) or autumn (October). Container seedlings can be planted throughout the growing season.

Planting procedure

1. Prepare a planting hole measuring 40 × 40 × 40 cm.
2. Place a layer of gravel at the bottom to ensure drainage.
3. Mix ripe compost into the excavated soil.
4. Plant the seedling so that the root collar is at the level of the surrounding soil.
5. Water thoroughly and mulch the surface.
6. When planting multiple shrubs, maintain a spacing of 1.5-2 m.

Important warning -- spreading via root shoots

Wolfberry spreads intensively via underground root shoots and without limitation can occupy a considerable area of the garden. Possible solutions:

• Plant the shrub in a root barrier -- a plastic edging sunken 40-50 cm deep into the ground.
• Regularly remove new shoots, preferably immediately after their appearance.
• Cultivate in a sufficiently large container (min. 40 liters).

Care and pruning

Watering

After establishment in the first season, wolfberry is very tolerant of drought. Water regularly only in the first year and during periods of prolonged summer drought. Excessive watering harms the shrub more than helps -- it promotes root rot and weakens the plant.

Fertilizing

Wolfberry is undemanding in terms of nutrients. In spring, apply ripe compost or universal fertilizer with a balanced NPK ratio. Over-fertilization with nitrogen leads to vigorous vegetative growth at the expense of fruitfulness -- the shrub then produces many leaves but few fruits.

Pruning

Regular pruning is essential for good yields and maintaining a compact shrub shape.

When to prune: At the end of winter, ideally in February or March, before new growth begins.

How to prune:
- Remove dead, crossing and overly dense branches.
- Shorten long drooping shoots to approximately one-third of their length.
- The aim is an open, airy crown with enough light for all branches.
- Goji fruits on one-year-old shoots -- always leave enough young wood.

Without regular pruning, the shrub becomes dense, fruits are smaller and harder to access during harvest.

Harvest and processing

Harvest time

Berries ripen gradually from August to October, sometimes until the first frosts. You can identify ripe fruits by their deep red color and easy separation from the stem.

How to harvest

• Pick berries by hand or shake them onto a spread cloth or pad.
• Harvest exclusively in dry weather -- wet fruits quickly mold.
• Note: Fresh goji berries may cause mild skin irritation in more sensitive individuals due to their saponin content. Sensitive growers should wear gloves.

Processing and consumption

Drying (most common method):
- Spread berries in a single layer on a sieve or baking paper.
- Dry in a dehydrator at 40-50 °C for 12-24 hours, or in an oven at 50 °C with the door slightly open.
- When air-drying, use a sunny and well-ventilated location -- drying time is 3-7 days, only in dry weather.
- Properly dried berries are elastic and gummy, not hard and brittle.

Other processing methods:
- Fresh: Directly from the shrub, in smoothies, muesli or yogurt
- Freezing: Spread on a tray, freeze and transfer to a bag -- berries won't stick together
- Tea: From fresh or dried berries, can be combined with rosehip or ginger
- Tinctures and extracts: Maceration in alcohol for long-term preservation of active compounds

FAQ -- Frequently asked questions

How long before goji starts bearing fruit?

First fruits may appear as early as the second year after planting, but full and stable yield usually occurs from the third year onwards. A mature shrub in favorable conditions will produce 1-3 kg of berries per season.

Is goji from your own garden as good quality as store-bought dried berries?

Homemade goji berries are fresh and contain no preservative additives or sulfur dioxide, which is commonly used in commercially dried imported berries. Taste-wise, homegrown fruits may be more delicate than Tibetan varieties, but the nutritional value is equivalent and compared to long-stored imported goods is often higher.

Can goji grow in a pot on a balcony?

Yes, with certain limitations. The shrub needs a container with a volume of at least 30-40 liters. In a container it will be smaller and the yield lower, but for growers without a garden it is a fully functional solution. In winter, wrap the container in insulating material or move it to a protected location to prevent root frost.

Are goji berries safe for everyone?

Goji berries may interact with certain medications, particularly warfarin and blood pressure regulating drugs. If you take medication, consult your doctor about regular goji consumption. For healthy individuals without medication, goji berries are a safe and nutritious food suitable for daily inclusion in your diet.
