How to grow Japanese Hop for the first time

8steps

Start with a simple, light-loving Japanese Hop plant in your garden for a beginner-friendly experience.

  1. 1

    What you'll need

    A healthy Japanese Hop plant or seeds, a trowel, and mulch.

  2. 2

    Best time to plant

    Plant in spring after the last frost, when soil is workable.

  3. 3

    Soil and container prep

    Choose a location with light to partial shade. Ensure the soil is well-draining and rich in organic matter.

  4. 4

    Sowing or transplanting

    Transplant young plants 3-4 meters apart, as they can grow quite large. If starting from seed, sow them indoors about 6 weeks before planting outside.

  5. 5

    First two weeks

    Water regularly to keep the soil moist but not waterlogged. Monitor for any signs of pests or diseases.

  6. 6

    Ongoing care

    Provide a sturdy trellis for support as it grows. Water deeply once a week, especially during dry spells. Fertilize in early spring with compost.

  7. 7

    Harvest or pruning

    Prune in late winter to maintain shape and encourage new growth. Harvest young shoots and leaves for culinary use.

  8. 8

    Common mistakes

    Overwatering, not providing enough support, and neglecting to prune can lead to problems with Japanese Hop plants.
