Pruning Hops Plants: How and When to Do It
If you're a homebrewer or just a lover of beer, you may have considered growing your own hops plants. Hops are the flowers that impart bitterness, flavor, and aroma to beer, making them an essential ingredient. However, hops plants can get unruly if left to their own devices, which is why pruning is an important part of their care.
What Is Pruning?
Pruning is the act of selectively removing parts of a plant to shape it, remove damaged or diseased growth, and promote healthy growth. In the case of hops plants, pruning serves several important purposes:
- Controlling the size and shape of the plant
- Promoting airflow and reducing the risk of disease
- Encouraging the development of lateral shoots (sidearms) that produce hops
- Removing old or unproductive growth to focus the plant's energy on new growth
When to Prune Hops Plants
Hops plants should be pruned in early spring, before new growth begins. This allows you to see the structure of the plant and make informed decisions about what to prune. It's also easier to see and remove any old or dead growth before new growth obscures it. Pruning later in the season can still be done, but it's best to avoid pruning after midsummer, as this can reduce the yield of hops cones.
How to Prune Hops Plants
Pruning hops plants is a straightforward process, but it does require some attention to detail. Here's how to do it:
Step 1: Assess the Plant
Before you start pruning, take a good look at the plant and identify any areas that need attention. Look for old or diseased growth, as well as any shoots that are growing in undesirable directions. You'll want to focus on removing these first.
Step 2: Remove Old Growth
Using a pair of sharp pruning shears, cut away any old or unproductive growth. Look for brown, woody stems with no leaves or buds. These stems won't produce hops and can actually hinder the growth of new shoots. Cut them down to the base of the plant.
Step 3: Train Sidearms
The main stem of the hops plant will produce several sidearms, or lateral shoots, which are where the hops cones will grow. Choose two or three of the strongest sidearms and train them up a support system (such as a trellis or pole). Remove any weaker sidearms, as they will compete with the stronger ones and reduce overall yield.
Step 4: Cut Back the Top Growth
Once you've removed any old growth and trained the sidearms, it's time to cut back the top growth of the plant. This will help promote lateral shoot development and prevent the plant from getting too tall and spindly. Cut back the top growth by about half, leaving a few leaf nodes intact to encourage new growth.
Pruning hops plants is an important part of their care and can help you achieve a healthy, productive crop of hops cones. By pruning in early spring and following these simple steps, you can keep your hops plants under control and ensure a bountiful harvest.
