A Guide to Growing Hops in Pots: From Planting to Harvesting

Introduction

Space constraints can be a hurdle for cultivating hops. But worry not, as I divulge the secrets to successfully growing hops in a container.

Understanding Hops

What Are Hops?

Hops are the flowers of the Humulus lupulus plant. They are a critical element in brewing. Hops can impart bitterness and contribute to beer's aroma and stability.

Varieties of Hops Suitable for Container Gardening

The sprawling nature of traditional hop plants is not suitable for container gardening. But you can use dwarf and compact varieties. Consider First Gold for a fruity hint, Fuggle for earthy tones, or Nugget for a robust, bitter edge. These have shorter vines and still produce an impressive yield.

Selecting the Right Container

Factors to Consider

When selecting pots, you should consider hops variety, your climate, and the available space. Some hop strains can grow rather vigorously. They require deep and wide pots for their roots to spread.


If you're in a cold climate, insulated containers can help protect the roots. Be sure to also consider the load-bearing capacity of your desired pot. Mature hop plants are quite hefty.

Ideal Size and Material

Hop plants are climbers by nature. They need a sturdy, sufficiently deep pot to support the growth. Plastic pots can offer insulation. While terracotta, wood, or metal containers can provide better breathability for the soil. In terms of size, a container at least 18 inches in diameter and 24 inches deep is recommended for each hop plant.

Drainage and Aeration

Without proper drainage, hop roots can rot. This potentially leads to the failure of your crop. Ensure your pots have ample drainage holes. Consider elevating the pots off the ground to promote air circulation.

Preparing the Potting Mix

Tips for Enhancing Soil Drainage and Fertility

The soil is the lifeblood of hops in a pot. It needs to be nutrient-rich and well-draining. Opt for a potting mix that is light and fluffy. Make sure it contains perlite and vermiculite to improve aeration and drainage. Enrich the soil with compost and slow-release organic fertilizers.

pH Considerations

Ensure the pH levels are between 6 and 7. To adjust the pH, you might need to incorporate some materials. For example, dolomite lime for a more alkaline condition or elemental sulfur for an acidic environment. Water the soil thoroughly and consistently. Avoid waterlogging the roots, as hops detest having their feet wet.

How to Grow Hops in Pots?

Hops require plenty of sunlight. So pick a spot on your patio or balcony with 6-8 hours of direct sunlight daily. Mix equal parts of garden soil, compost, and peat moss. This will ensure proper moisture retention while maintaining adequate drainage.


If you’re starting from rhizomes, soak them in water for a few hours before growing hops in pots. If you have established hop plants, remove them carefully from their original container. Teasing the roots gently to encourage outward growth before planting.

Spacing and Depth

To ensure a healthy hop harvest, plant one rhizome or plant in each pot. If planting more than one, space them at least three feet apart. The depth to plant the rhizome is crucial. Place the hop about two inches deep with the shoots facing upwards. You should see growth within the first two weeks if you plant the hop in the spring.

Watering and Initial Care

Water immediately after growing hop rhizomes in pots. Continue to keep the soil consistently moist, not waterlogged. You should also avoid letting the soil dry out. You may need to water them daily, especially in the summer heat.


Use a balanced liquid fertilizer every two weeks after the initial planting. Mulching can also help maintain soil moisture and suppress weeds.

Providing Support Structures

The correct support is vital for your hop plants. They eventually will reach heights of 15 to 20 feet. Without proper training and support, the bines can become tangled. This reduces airflow and potentially promotes disease.


Choose a support structure at least 10 feet high. The robust materials will can withstand the weight of the mature plant. An A-frame design or a simple trellis against a wall will allow for both climbing and easy harvesting. Ensure the structure is stable and won't topple over taking your hops with it.

Watering and Fertilizing

Watering Hop Plants in Pots

The key to watering hops is consistency. You should keep the soil moist, not too wet or too dry. Water your plants deeply when starting hop rhizomes in pots. Allow the surface to dry out between waterings. A simple check is to stick your finger into the soil. If the top inch is dry, it's time to water.

Nutritional Requirements

Hops are heavy feeders. They require soil rich in organic matter when planting hops rhizomes in pots. You can apply a balanced, water-soluble fertilizer mixed at half-strength bi-weekly during the growing season.

Signs of Overwatering or Nutrient Deficiencies

Yellowing leaves can be a sign of overwatering or a nutrient imbalance. This could be an indication to adjust your watering schedule or increase the frequency of your feeding. If the plant is not responding to your efforts, a soil test could provide insight into the hops need.

Managing Pests and Diseases

Common Pests and Diseases

Hop aphid, red spider mites, Japanese beetles and leafhoppers are common pests. Downy mildew, verticillium, hop mosaic virus, and powdery mildew are common diseases.

Organic Methods for Pest and Disease Management

Employ organic methods to mitigate the risk and impact of pests and diseases. Introduce beneficial insects to keep aphid populations in check. For example, ladybugs.


Neem oil and insecticidal soaps offer gentle rebukes to pests. They can also help prevent certain diseases. For fungi, a solution of potassium bicarbonate sprayed on the leaves can act as a deterrent.

Early Detection and Prevention Strategies

Regularly prune away diseased or damaged plant parts. This can halt the spread of illness. Ensure proper air circulation around the plant. Avoid overwatering to keep fungi at bay. You should isolate new plants for time help. This can screen any potential diseases before integrating them into a larger garden.

Training and Pruning

Techniques for Training

Training is crucial for controlling the direction of hop growth. This leads to more effective use of vertical space. Your hops will be stronger and produce higher yields.


You can train hop bines in several ways. One common method is to twist excess shoots into the main bine. You might also employ the fan method. Arrange the branches along the support structure like a fan.

Timing and Frequency of Pruning

Pruning involves removing basal and side shoots early in the growing season. This encourages the plant to put its energy into the main bine. Pruning should begin as soon as your hops start to grow, usually in spring.


Continue pruning to ensure there are no more than a handful of shoots extending from the main bine. This encourages upward growth. The energy will go into the production of cones, not excess foliage. Be careful not to over-prune. This can stress the plant.

Harvesting Hops in Pots

Signs of Maturity

Harvest when the cones are dry to the touch and start to feel papery, with a slight spring-back response. They will also exude a stronger scent. This is indicative of the aromatic oils that brewers covet.

Harvest Hops

Harvesting hops is a sensory experience. You feel the readiness, tactile in your hands, and fragrant to your nose. The best time to harvest is early morning, not long after the dew has evaporated. This can maximize their aromatic oils.

Drying and Storage

To preserve those oils, you must dry hops rapidly and thoroughly. Then, stored in airtight containers away from direct light and at refrigerator temperatures. You can use a food dehydrator or oven set to 'warm' for drying. Just be cautious of temperature to avoid losing those all-important oils.

Conclusion

With the right varieties, soil, and care, your hops will flourish. It's time to plant hops in pots. Start your hop gardening adventure today!
