How to grow Masterwort for the first time

7steps

Masterwort is a hardy perennial that's easy to grow for beginners, focusing on basic care and maintenance.

  1. 1

    What you'll need

    A small shovel or trowel, seeds or young plants, a container with drainage holes if planting in pots.

    Best time to plant

    Plant Masterwort in spring after the last frost or in fall before the first freeze.

  3. 3

    Soil and container prep

    Ensure soil is well-draining and slightly acidic, with a pH of 7–7.5. Use a potting mix suitable for herbs if planting in containers.

    Sowing or transplanting

    Direct sow seeds outdoors once the ground is workable in spring. Alternatively, plant young seedlings in prepared soil.

  7. 7
