You can propagate hops by taking cuttings from healthy vines or by using rhizomes (underground stems) in late spring or early summer, ensuring well-draining soil and proper support for the new plants. 

Here’s a more detailed guide:

1. Propagation from Cuttings:

  • Timing: Late spring or summer is ideal for taking cuttings. 
  • Gathering Cuttings: Select healthy, mature vines, preferably from the bottom of the plant. 
  • Preparing Cuttings: Cut the vines into sections (4-6 inches) with at least one or two buds (eyes) per section. 
  • Planting Cuttings: Ensure well-draining soil and amend with compost if needed. Plant the cuttings 1-2 inches deep, spaced 3 inches apart.  Keep the soil moderately moist but not soggy.  Provide support (stakes or other structures) for the new shoots as they grow. 

Watering: Water regularly, especially during establishment, but avoid overwatering. 

2. Propagation from Rhizomes:

  • What are Rhizomes? Rhizomes are underground stems that can produce new plants. 
  • Timing: Late spring or early summer is the best time to harvest and plant rhizomes. 
  • Harvesting Rhizomes: Dig around the base of the parent plant and carefully extract the rhizomes. 
  • Preparing Rhizomes: Cut the rhizomes into sections (5-6 inches) with a sharp, sterile knife. 
  • Planting Rhizomes: Plant the rhizome sections 2 inches below the soil surface. Keep the area moderately moist for a week.  Provide support for the new shoots as they grow. 

Watering: Water regularly, especially during establishment, but avoid overwatering. 

3. General Tips for Propagating Hops:

  • Soil: Ensure well-draining soil and amend with compost to improve fertility. 
  • Sunlight: Hops need at least 6 hours of sunlight per day. 
  • Support: Provide strong support (trellises, stakes, or other structures) for the vines as they grow. 
  • Pest and Disease Control: Monitor for pests and diseases and take appropriate action if necessary. 
  • Pruning: Prune the vines after harvest to encourage new growth and control spread. 
  • Mulch: Apply a layer of mulch to help retain moisture and suppress weeds. 
  • Fertilizing: Fertilize regularly, especially during the growing season, with a balanced fertilizer.
