How to grow African basil for the first time

7steps

African basil is a forgiving plant for beginners, making it an excellent choice for your first gardening project.

  1. 1

    What you'll need

    Seeds or cuttings, small pots if starting indoors, a sunny spot in the garden.

  2. 2

    Best time to plant

    Plant seeds directly outdoors after all danger of frost has passed, or start cuttings indoors 4-6 weeks before the last frost.

  3. 3

    Soil and container prep

    Use well-draining soil in containers at least 12 inches wide. In the garden, prepare a sunny spot with loose, fertile soil.

  4. 4

    Sowing or transplanting

    Direct sow seeds 0.5 inches deep, spaced about 6-8 inches apart. Transplant cuttings into moist soil, keeping them in partial shade until established.

  5. 5

    First two weeks

    Water regularly to keep the soil consistently moist but not waterlogged. Provide light shading if transplanting from indoors.

  6. 6

    Ongoing care

    Water when the top inch of soil feels dry, and fertilize every 4-6 weeks with a balanced liquid fertilizer. Pinch back flowers to encourage bushier growth.

  7. 7

    Harvest or pruning

    Prune regularly by cutting stems just above a leaf node to promote new growth and maintain shape. Harvest leaves as needed for use in cooking.
