As a sommelier and brewer, I can confidently say that hops do not necessarily have to be grown vertically. However, growing hops vertically has several advantages and is the preferred method for most hop growers.
One of the main reasons for growing hops vertically is to maximize their exposure to sunlight. Hops are sun-loving plants and require a significant amount of sunlight to thrive and produce high-quality cones. By training hops to climb vertically, you can ensure that all parts of the plant receive adequate sunlight throughout the day. This helps in photosynthesis and promotes healthy growth.
Another benefit of vertical growth is space efficiency. Hops are vigorous climbers and can grow up to 20 feet in a year. By training them to grow vertically, you can make the most of limited garden space. This is particularly useful for backyard growers who may have limited space but still want to cultivate hops for brewing.
Vertical growth also aids in the management and maintenance of hops plants. When hops are allowed to climb vertically, it becomes easier to prune and harvest the cones. Pruning helps in controlling the height and spread of the plant, making it more manageable and less prone to disease and pests. Harvesting becomes more accessible as the cones are at a convenient height, allowing for easier picking.
There are various structures you can use to support the vertical growth of hops. If you have a balcony or existing arbor, you can train the hops to climb these structures. You can also create a trellis using wooden or metal posts and wire or twine. The key is to provide a sturdy and secure support system for the hops to climb.
In my personal experience, I have found that training hops to grow vertically yields better results in terms of plant health and cone production. I have seen healthier plants with larger and more abundant cones when compared to hops that were allowed to sprawl on the ground or grow in a less structured manner.
While hops do not necessarily have to be grown vertically, it is highly recommended for optimal growth and yield. Vertical growth ensures maximum sunlight exposure, space efficiency, and ease of plant management. Whether you have a balcony, arbor, or can create a trellis, providing a vertical structure for your hops will likely result in healthier plants and more bountiful harvests.
