When to plant
Plant rhizomes in spring after last frost. Perennial in zones 4–8. First year: sparse production. Year 2: full production. A single plant can grow 20–25 feet per season and produce 1–3 lbs of dried hops. Extremely vigorous — give it plenty of space and a tall, sturdy support.
Soil & site
Deep, rich, well-drained soil with very high organic matter. pH 6.0–8.0. Hops have an extremely deep, vigorous root system — prepare soil deeply and amend generously with compost. Install a very sturdy support system at least 18 feet tall.
Feeding
Heavy feeder. In early spring, apply a high-nitrogen fertilizer to drive initial growth. Through the season, switch to a balanced fertilizer. Potassium and phosphorus support cone development in summer. Annual mulching with compost maintains soil fertility.
Common problems
Powdery mildew and downy mildew (both common). Spider mites in hot weather (the most damaging pest). Hop aphids. Verticillium wilt. Japanese beetles eat the leaves. Disease-resistant varieties greatly reduce spraying needs.
When to harvest
Hop cones are ready in late summer. Ready cones: feel dry and papery, spring back when squeezed, have a strong resinous aromatic smell, and yellow lupulin powder falls out when the cone is split open. Green, wet, compressible cones need more time.
How to harvest
Cut the entire bine down from the top, pulling the string or wire to the ground. Strip cones by hand into buckets or boxes. Wear long sleeves — hop plant hairs can irritate skin. Dry cones immediately in a single layer at 140 degrees F until completely dry and crumbly inside. This takes 4–8 hours in a food dehydrator.
Storage & use
Vacuum-seal dried hops and freeze immediately — hop resins oxidize quickly and lose bitterness and aroma at room temperature. Frozen dried hops keep 1–2 years. Used in homebrewing for bitterness, aroma, and flavoring.
