Hops are vigorous, climbing vines known for their papery, cone shaped flowers used in brewing. They grow incredibly fast during the summer months and need a sturdy trellis to support their heavy bines. You will love watching them climb as they create a lush, green screen in your garden.

Care
Provide a tall, sturdy structure for the bines to climb and ensure they get plenty of sun. Watch for aphids or spider mites on the undersides of leaves during hot, dry spells. Keep the soil consistently moist but well drained to support their rapid growth.
- Watering
- Keep the soil evenly moist, especially during the peak of summer heat.
- Feeding
- Feed with a balanced fertilizer throughout the active growing season.
- Pruning
- Cut the bines back to the ground once they die back in late autumn.
- Repotting
- Hops are best grown in the ground, but if in containers, refresh the soil every few years.

- Stunted growth despite regular feeding.
Safety
- People
- The rough hairs on the stems and leaves can cause contact dermatitis in sensitive individuals.
- Pets
- Hops are toxic to dogs and can cause malignant hyperthermia if ingested.
- Children
- The stems are covered in tiny, hooked hairs that can scratch delicate skin, so keep children away from the vines.
- Contact allergens
- The glandular hairs on the leaves and stems are known to cause skin irritation or rashes upon touch.
- Airborne allergens
- The pollen may trigger mild allergic reactions in sensitive individuals during the flowering season.
- Edibility
- While the cones are used for brewing, they can cause digestive upset in some people and are highly toxic to dogs.

Growing it
- Propagation
- division, cuttings
- When to plant
- spring
- Overwintering
- Cut the vines back to the ground after the first hard frost. Apply a thick layer of mulch over the crown to protect it from extreme temperature fluctuations.
- In containers
- They can grow in large containers of at least 40 liters, but they will need a tall trellis to support their rapid growth.
Rhizome Division
- 1. Wait until early spring when the plant is dormant.
- 2. Carefully dig around the root mass to expose the rhizomes.
- 3. Cut a section of rhizome that has at least two healthy buds.
- 4. Replant the section immediately in fertile soil.
Plant low growing ground covers around the base to shade the roots, as hops prefer cool feet and a sunny head.
Grows well with
- Nasturtium · They act as a living mulch to keep the soil cool and moist.
- Garlic · Their strong scent helps deter some common garden pests.
Similar species
- Japanese Hop · An annual relative that is often considered invasive in many regions.

- It is possible, but they require a very large container and frequent watering.
Where the name comes from
The name Humulus comes from the Latin word for earth, referring to its habit of trailing on the ground if not supported. Lupulus is a diminutive of lupus, meaning wolf, as it was once thought to choke out other plants like a wolf in a sheepfold.
Good to know
- Hops grow incredibly fast, sometimes up to 20 centimeters in a single day.
- The female flowers, known as strobiles, are the part used for brewing beer.
- Hops were historically used to preserve beer before refrigeration existed.
- The plant dies back to the ground every winter and regrows from the roots in spring.
