Borage - Borago officinalis

Growing Borage - Alkaline Well-Draining Substrate, Full Sun Position, Moderate Watering

Basic Requirements for Growing Borage

Borage (Borago officinalis) is an undemanding annual herb that thrives in garden conditions with minimal care. Success in growing this beneficial plant depends on meeting several basic requirements that reflect its Mediterranean origin.

Substrate and Soil Requirements

Borage prefers alkaline to neutral soil with a pH between 6.5 and 8.0. The substrate must be well-draining to prevent root rot, which is the most common problem when growing this plant. Heavy clay soils should be improved with sand or perlite to increase their permeability.

The ideal substrate composition includes:

Garden soil or quality potting mix as the base
Sand or perlite for drainage (approximately 20-30% of the mixture)
Compost or well-rotted manure for nutrients
Garden lime or dolomitic limestone for alkaline pH

Light Requirements

Borage requires an exclusively sunny position with at least 6-8 hours of direct sunlight daily. In shaded conditions, the plant grows elongated, produces fewer flowers, and is more susceptible to fungal diseases. Full sun ensures:

Compact and robust growth
Abundant flowering throughout the season
Higher content of beneficial essential oils
Better resistance to pests and diseases

Watering Regime

Moderate watering is key to successful borage cultivation. The plant is relatively drought-tolerant once established and prefers drier conditions to constant moisture. Overwatering leads to root rot and reduced vitality.

Watering principles:

Water only when the top layer of soil dries out
Water thoroughly but infrequently
Avoid waterlogging and standing water
Reduce watering frequency in cool and rainy weather
Young plants require more regular watering until established

Additional Growing Tips

Borage is an excellent companion plant in the vegetable garden, attracting pollinators and improving soil structure with its deep roots. The plant readily self-seeds, so it will return year after year if you allow some flowers to set seed.

Regular harvesting of young leaves and flowers encourages continued production and extends the harvest period. Borage typically reaches a height of 60-90 cm and spreads approximately 45-60 cm wide.

BORAGE (Borago officinalis)

Borage, also known as starflower, is cultivated primarily for its seeds, though the active compounds are found throughout the entire plant except the roots. It reaches a height of approximately 15-70cm, produces sturdy leaves, and has a cucumber-like flavor.

Borage contains essential oil and silicic acid. Fresh borage is rich in vitamin C. The seeds contain high amounts of gamma-linolenic acid.

The essential oil affects hormone secretion and the nervous system. Gamma-linolenic acid helps alleviate skin conditions. Borage oil is particularly applied for neurodermatitis. Silicon is important for cartilage nutrition and healthy growth of hair and nails.

Borage oil is recommended for treating dry or inflamed skin. People prone to neurodermatitis usually suffer from enzyme production disorders, and their bodies cannot produce gamma-linolenic acid on their own. This substance can be effectively obtained through borage application.

Borage herb has a beneficial effect on the adrenal glands. It is also recommended for brittle nails and fragile hair. The silicic acid contained throughout the plant has a favorable effect on hair and nail growth and strength.

Applications:

Smoothie: Pour 1/2 liter of buttermilk over 5 tablespoons of finely chopped borage herb. Add salt, pepper, and a little Tabasco.
Compress: Pour 1/2 liter of boiling water over 4 tablespoons of finely chopped borage herb, let steep for 10 minutes, then strain. Soak gauze or a cloth and apply several times daily.
Oil: Available for purchase. Apply to affected areas 2-3 times daily.
Fresh borage: Can be used as a flavoring in cucumber salad.

Important: Flowers and herb should not be used for extended periods.
