Growing Tips

  • Soak or gently scarify the seeds before sowing to encourage better germination.
  • Keep the seed-starting medium evenly moist without making it waterlogged.
  • Choose a deep planting area because liquorice develops an extensive root system.
  • Remove unwanted spreading growth regularly to keep established plants controlled.

Seed Storage

Store unused liquorice seeds in a cool, dry, dark location. Keep them in a sealed, moisture-resistant container away from heat and humidity. Avoid storing seeds where temperatures and moisture fluctuate frequently.

Unique Facts About Liquorice Seeds and Plants

  • Liquorice belongs to the legume family, Fabaceae.
  • The characteristic sweetness of liquorice roots comes largely from glycyrrhizin.
  • Its small blue to purple flowers resemble pea flowers and appear in summer.
  • The plant can become difficult to control once established because of its spreading root system.

Growing Instructions

Planting Season: Sow in spring when conditions are suitable for seedling growth. In colder climates, start seeds indoors and transplant after frost danger has passed.

Sowing: Prepare a deep, fertile seed-starting medium and lightly scarify or soak the seeds before planting.

Depth: Sow seeds about one-quarter inch deep and cover lightly with fine soil.

Spacing: Allow about twelve to eighteen inches between young plants, giving established roots adequate room to develop.

Sunlight: Grow in full sun for strong growth, although the plant can tolerate partial shade.

Soil: Use deep, fertile, moisture-retentive soil with good drainage. Loam or sandy soil is preferable, while heavy clay should be avoided.

Watering: Keep soil consistently moist during establishment. Water deeply during dry periods while avoiding standing water.

Germination: Germination may take several weeks. Seed preparation through soaking or light scarification can help overcome the seed coat and encourage more uniform emergence.

Transplanting: When seedlings are well established and large enough to handle, transplant them carefully without excessively disturbing the developing roots.

Fertilizing: Incorporate mature compost into the planting area before planting. Once established, avoid excessive nitrogen fertilizer, which can encourage foliage at the expense of root development.

Care: Keep the planting area weed-free while plants establish. Monitor for slugs, snails, spider mites, rust, and powdery mildew. Control spreading growth where necessary.

Flowering and Maturity: Liquorice produces blue to purple flowers during summer. The plant is perennial, but substantial root development takes more than a single growing season.
