The borage plant (also known as Borago officinalis) is a beautiful herb with star-shaped blue flowers and a long history in gardens and kitchens. It was used by ancient civilizations for its medicinal benefits, and today it’s appreciated for both its beauty and versatility. Whether you’re looking to attract pollinators or spice up your dishes, borage is an excellent plant to grow!

Growing Borage:

Borage is an easy-to-grow, low-maintenance herb that fits perfectly into any garden. Plant borage in early spring after the frost has passed, or start seeds indoors 3-4 weeks beforehand. Transplant seedlings once the soil is warm, ensuring they are hardened off first. Borage can grow in various soils as long as they drain well. Pick a spot with at least four hours of sunlight, keeping it clear of taller plants. It also grows well in containers.

Typically grown from seeds, plant them 1/4 to 1/2 inch deep. Thin seedlings when they reach 6 to 8 inches, spacing them 18 to 24 inches apart. No support structure is needed.

Care

  • Water: Borage prefers moderate watering. Keep the soil moist but not soggy, and let it dry out between waterings to prevent root problems. It’s pretty drought-tolerant once established.
  • Light: Borage loves sunlight! Make sure it gets at least six hours of direct sun each day. It can tolerate partial shade, but full sunlight is best for healthy growth and vibrant flowers.
  • Soil: Borage is not picky when it comes to soil. It can grow in poor soil, but well-drained, rich soil will lead to healthier plants. You can improve the soil by mixing in compost or organic matter.
  • Temperature: Borage thrives in mild to warm temperatures, between 60 and 75°F (15-24°C). It’s hardy enough to withstand cooler temperatures, but frost can damage young plants.

Pruning

Borage doesn’t need much pruning, but trimming it back can encourage more blooms and prevent the plant from getting too leggy. Cut back any yellow or dead leaves, and trim the stems if they start to look scraggly.

Common Pests

Most pests can be managed naturally by introducing beneficial insects, such as ladybugs, or by manually removing them from the plants. Additionally, the presence of borage in the garden can help repel harmful pests from nearby plants.
