7 Fertilizing Hops For Maximum Yield That Old Farmers Swear By

You’ve seen it happen: a hop bine rockets up its trellis, covered in lush, green leaves, looking like a champion. But when harvest time comes, the cones are sparse, small, and lacking that pungent aroma you were dreaming of. The difference between a pretty vine and a heavy harvest almost always comes down to one thing: a smart, season-long feeding strategy. These are the time-tested methods for fertilizing hops that deliver the goods, year after year.

Building a Rich Foundation for Your Hop Yard

The best fertilizer plan starts a year before you even plant your rhizomes. Hops are incredibly hungry and thirsty plants, and they perform best when their roots can draw from a deep, rich reservoir of nutrients and organic matter. Simply digging a hole in your lawn and hoping for the best is a recipe for a constant, uphill battle all season.

Before you do anything, get a simple soil test. You need to know your baseline pH and whether you’re starting with a deficiency in the big three: nitrogen (N), phosphorus (P), or potassium (K). Most hops prefer a slightly acidic soil, somewhere in the 6.0 to 7.0 pH range. The test results will tell you if you need to add lime to raise the pH or sulfur to lower it.

Your real goal is to build a living soil, not just a patch of dirt. Work several inches of high-quality, finished compost or well-rotted manure into the entire planned hop bed, not just the individual planting holes. This initial investment creates a soil structure that holds moisture, provides a slow, steady release of nutrients, and fosters the microbial life that helps a plant’s roots thrive. This work up front means less frantic fertilizing later.

Amending Planting Holes with Slow-Release Bone Meal

When it’s finally time to get those rhizomes in the ground, your focus shifts from the whole yard to the immediate root zone. This is where a targeted amendment can make a huge difference in getting the plant established quickly and strongly. The classic choice here is bone meal for one simple reason: phosphorus.

Phosphorus is the key nutrient for vigorous root development, and a strong root system is the engine that will power your hop bine’s explosive growth. Bone meal is an ideal source because it breaks down slowly, providing a steady supply of phosphorus right where the new roots need it most. Unlike synthetic fertilizers, it won’t burn the delicate new growth.

The application couldn’t be simpler. As you’re backfilling the planting hole around your rhizome, mix a generous handful of bone meal directly into the soil. This ensures the nutrient is available in the root zone throughout that critical first season. It’s a small step that pays off with a more resilient and productive plant for years to come.

Early Spring High-Nitrogen Top Dressing

The moment you see those first hop shoots poke through the soil in spring, the race is on. In the next two months, that tiny shoot needs to become a 20-foot bine, and the fuel for that incredible sprint is nitrogen. An early spring feeding is essential to give the plant the energy it needs for this vegetative explosion.

This is the time for a high-nitrogen fertilizer. You’re looking for something where the first number in the N-P-K ratio is significantly higher than the other two. Great organic options include:

• Blood Meal: A fast-acting, potent source of nitrogen.
• Feather Meal: Slower to break down, providing a more sustained release.
• Fish Meal: A balanced choice that also offers valuable trace minerals.

Don’t just dump the fertilizer on the ground. Sprinkle the recommended amount around the base of the plant, keeping it a few inches away from the new shoots. Gently scratch it into the top inch or two of soil with a hand cultivator, then water it in well. This helps the nutrients get down to the roots and start working immediately.

Be careful not to overdo it. The goal is to power the initial climb, but too much nitrogen late in the season can result in a giant, leafy plant with fewer of the cones you’re actually after. This early boost is a targeted strike, not a season-long carpet bombing.

Side-Dressing with Well-Rotted Animal Manure

Once your bines are established and climbing vigorously—say, three to four feet tall—it’s time for their first big meal of the season. This is where well-rotted animal manure shines. It’s a complete, balanced fertilizer that provides not only N-P-K but also a full spectrum of micronutrients and, just as importantly, organic matter.

First, let’s be clear about "well-rotted." Fresh manure is high in ammonia and salts that will scorch your plants. Proper composted or aged manure should be dark, crumbly, and smell earthy, not foul. If you’re getting it from a local farm, make sure it has aged for at least six months to a year.

The technique is called "side-dressing." Apply a one-to-two-inch layer of the manure in a wide circle around the base of the hop plant, starting about six inches away from the bines and extending out to the drip line. This placement encourages the roots to spread out in search of nutrients. Every time you water or it rains, the nutrients will slowly leach down into the root zone, providing a steady, reliable food source during the most demanding growth phase.

Liquid Feeding with Diluted Fish Emulsion

Think of liquid feeding as a quick-energy snack for your hops. While soil amendments like compost and manure provide a slow, steady diet, a liquid feed offers a fast-acting boost that the plant can absorb almost immediately. This is particularly useful during periods of explosive growth or if the plant looks a little pale or stressed.

Fish emulsion is the classic choice for a reason. It’s a fantastic source of readily available nitrogen and trace minerals that can green up a plant in a matter of days. The only real downside is the potent, fishy smell, but it usually dissipates within a day or so. Don’t let that deter you; the results are worth it.

Mix one or two tablespoons of fish emulsion concentrate into a gallon of water and use it to drench the soil at the base of the plant. Start this supplemental feeding when the bines are a few feet tall and continue every two to three weeks until the first hop burrs appear. Once the plant switches its energy to producing cones, you’ll want to back off the high-nitrogen feeds.

Foliar Feeding with Nutrient-Rich Compost Tea

Foliar feeding is the practice of spraying nutrients directly onto the plant’s leaves, which can absorb them in small amounts. While it’s no substitute for healthy soil, it’s an excellent way to deliver micronutrients and give your plants a supplemental boost. The absolute best tool for this job is actively aerated compost tea.

This isn’t just compost soaked in water. True compost tea is brewed by bubbling air through a mixture of compost, water, and a simple sugar (like molasses) for 24-48 hours. This process multiplies the beneficial bacteria, fungi, and protozoa from the compost, creating a living, nutrient-rich solution.

Use a pump sprayer to apply the tea, making sure to coat both the tops and, more importantly, the undersides of the leaves. The best time to spray is in the cool of the early morning before the sun gets intense. Beyond providing a quick nutrient hit, a major benefit of compost tea is disease suppression. By coating the leaves with beneficial microbes, you create a competitive environment that can help ward off common hop afflictions like powdery and downy mildew.

Applying Wood Ash for a Late-Season Potash Boost

As summer wears on and your hop bines are covered in burrs that are beginning to swell into cones, the plant’s nutritional needs change dramatically. Its demand for nitrogen drops, while its need for potassium (also known as potash) skyrockets. Potassium is vital for cone development, density, and the production of those all-important alpha acids and essential oils.

Hardwood ash from your fireplace or wood stove is an excellent, traditional source of potassium and calcium. However, this is one amendment you must use with caution. Wood ash is highly alkaline and will raise your soil’s pH. Only use it if your soil is naturally acidic or neutral, and always use it sparingly. Applying it to already alkaline soil can lock up other nutrients, causing more harm than good.

If your soil is a good candidate, a very light dusting around the base of the plant in mid-to-late summer is all you need. Gently work it into the surface of the soil and water it in. This provides that critical late-season boost, helping the plant channel its energy into producing a heavy, high-quality crop of cones.

Winter Cover Crops to Fix Nitrogen Naturally

The most forward-thinking fertilization happens after you’ve harvested the last cone. Once you’ve cut the bines back for the winter, the soil in your hop yard can be put to work building fertility for the following spring. Planting a winter cover crop is like putting money in the bank for next year’s nutrient budget.

Legumes like hairy vetch, crimson clover, or winter field peas have a remarkable ability. They form a symbiotic relationship with soil bacteria that allows them to pull nitrogen right out of the atmosphere and "fix" it into nodules on their roots. This is nature’s own fertilizer factory, and it’s completely free.

Simply broadcast the seeds over your hop yard in the early fall. The crop will grow through the fall and go dormant in winter. In early spring, before the hops emerge, you can either till the cover crop into the soil or simply chop it down and leave it on the surface as a "green manure." As it decomposes, it releases a massive amount of organic matter and that precious, naturally-fixed nitrogen for your hungry hops.

Feeding your hops isn’t a single task, but a season-long conversation. By learning to read the plant’s needs—from the initial nitrogen rush of spring to the late-summer craving for potassium—you can move beyond simply growing a vine to truly cultivating a bountiful harvest. Observe, adapt, and your efforts will be rewarded with fragrant, heavy cones.
