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
What you'll need
A healthy Japanese Hop plant or seeds, a trowel, and mulch.
2
Best time to plant
Plant in spring after the last frost, when soil is workable.
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
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
First two weeks
Water regularly to keep the soil moist but not waterlogged. Monitor for any signs of pests or diseases.
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
Harvest or pruning
Prune in late winter to maintain shape and encourage new growth. Harvest young shoots and leaves for culinary use.
8
Common mistakes
Overwatering, not providing enough support, and neglecting to prune can lead to problems with Japanese Hop plants.
