Step by step

    Plant

    Plant at the same depth as in its pot, 30 cm apart, in a sunny, sheltered spot. Firm in.

  2. 0–1 days after “Plant” · Late April

    Water In

    Water well, then keep just moist while it settles in.

  3. 30–51 days after “Water In” · Late May – mid June

    First Light Harvest

    Once it is growing strongly, snip a few sprigs — never more than a third of the plant at once.

Every year

  • June
    Move Outside

    Stand the pot in a sunny, sheltered spot once nights are warm.

  • August
    Main Harvest

    Cut stems just before flowering, when sweetness peaks; dry the leaves.

  • September
    Bring Indoors

    Bring indoors before the frost and water sparingly through winter.
