Introduction

Borage is a hardy herb known for its star-shaped blue flowers and cucumber-flavoured leaves. Perfect for attracting pollinators like bees, borage is a low-maintenance addition to any Australian garden.

Why Grow Borage?

  • Pollinator Magnet: Attracts bees and other beneficial insects.
  • Edible Uses: Leaves and flowers can be used in salads, teas, or as a garnish.
  • Easy to Grow: Thrives in a variety of conditions with minimal care.

Overview of Borage Varieties

Borage is typically grown as a single species, but gardeners can enjoy its unique benefits:

  • Standard Blue Borage: Known for its vivid blue flowers, this variety is the most common and versatile.
  • White Borage: A less common variant with white flowers, offering a slightly more delicate appearance.

Nutritional and Culinary Benefits

Borage is valued for its health benefits and versatility in the kitchen:

  • Rich in Nutrients: Contains omega-6 fatty acids, potassium, and antioxidants.
  • Culinary Uses: Young leaves can be added to salads, soups, or teas, while flowers are often used as garnishes or frozen in ice cubes for drinks.
  • Medicinal Uses: Traditionally used to soothe inflammation and improve skin health.

Planting Borage

Best Seasons for Planting

  • Temperate Regions: Sow seeds in spring or autumn.
  • Subtropical Regions: Best planted in autumn to avoid summer heat.
  • Cooler Regions: Plant in spring after the last frost.

Soil Preparation and Amendments

  • Soil Type: Borage thrives in well-drained soil but can adapt to poor soils.
  • pH Level: Slightly acidic to neutral soil (pH 6.0–7.0) is ideal.
  • Preparation: Add compost or aged manure to enrich the soil and promote healthy growth.

Seed Spacing and Planting Depth

  • Spacing: Sow seeds 30–60 cm apart to allow the plant’s bushy habit to flourish.
  • Depth: Plant seeds 1 cm deep. Keep the soil moist during germination, which occurs in 5–10 days.

Caring for Borage Plants

Watering Schedule

  • Borage is drought-tolerant but performs best with consistent moisture during dry spells.
  • Avoid waterlogging, as it may cause root rot.

Fertilisation and Maintenance

  • Borage typically does not require additional fertiliser if the soil is rich.
  • A light compost dressing mid-season can boost flower production.

Managing Weeds

  • Mulch around plants to suppress weeds and retain soil moisture.

Pest and Disease Management

Common Pests

  • Aphids: May cluster on stems and leaves, weakening the plant.
  • Caterpillars: Occasionally feed on leaves.

Organic and Preventative Solutions

  • Aphids: Use neem oil or a soapy water spray to deter them.
  • Preventive Measures: Encourage natural predators like ladybirds, and avoid overcrowding plants for better air circulation.

How to Grow Borage in Pots

Borage grows well in pots, making it ideal for small gardens or patios.

  • Choose the Right Pot: Use a pot at least 30 cm deep with drainage holes.
  • Soil: Fill with a loose, nutrient-rich potting mix amended with compost.
  • Planting: Sow seeds 1 cm deep, spacing them at least 15–20 cm apart.
  • Watering: Keep the soil consistently moist but not soggy.

Harvesting Borage

Recognising Maturity

  • Leaves: Harvest young, tender leaves when the plant is actively growing. Older leaves may become rough and prickly.
  • Flowers: Pick flowers as they open for maximum freshness and flavour.

Proper Harvesting Techniques

  • Use clean scissors or pruning shears to cut flowers and leaves, leaving the base of the plant intact for continued growth.

Storing and Preserving Borage

  • Short-Term Storage: Store freshly picked leaves and flowers in a plastic bag in the refrigerator for up to three days.
  • Preservation: Freeze flowers in ice cubes or dry leaves for use in teas.
