Growing Big Garlic Bulbs: Tips for Success

There’s something deeply satisfying about pulling a hefty garlic bulb from the soil—especially when you’ve nurtured it from start to finish.

We’ve grown garlic in our own backyard for years now, and over time, we’ve learned what works, what doesn’t, and what actually makes a difference. If you’re chasing those big, fragrant bulbs that add real character to your meals, you’re in the right place.

Start with the Right Garlic Variety

We always begin by picking a variety that suits both our taste buds and our climate. Some garlic just grows better in certain places—there’s no getting around it. And honestly, the difference between a good garlic and a great one often starts right here.

Hardneck garlic, with its bold flavor and central flower stalk (the scape), tends to thrive in colder climates. You’ll get fewer cloves, but they’re often larger and easier to peel. Softneck garlic, on the other hand, is a bit more flexible with growing conditions and lasts longer in storage—handy if you’re stocking up for winter stews.

If you’re unsure where to begin, try proven performers like ‘Music’ or ‘German Extra-Hardy’ for hardneck types, or go with ‘Silverskin’ or ‘Inchelium Red’ for softneck. Personally, we like to grow a mix. It keeps things interesting in the kitchen.

Prepare the Soil for a Successful Harvest

Garlic’s not high maintenance, but it does have standards. The soil? That’s where it either flourishes or fizzles. We always test our soil first—nothing fancy, just enough to check pH and nutrient levels. Garlic prefers soil with a pH between 6.0 and 7.0. If it’s out of range, we tweak things: sulfur or compost for high pH, lime for low.

Next up—nutrients. Garlic needs nitrogen to build its leaves, and phosphorus and potassium to plump up those bulbs. We work in compost, maybe some aged manure, and top it off with a balanced fertilizer.

Drainage is non-negotiable. If your soil stays soggy, garlic roots will rot, and you’ll be left with disappointment come harvest time. We’ve had great results using raised beds or gently sloped rows. And always till deep—8 to 10 inches—to let roots stretch comfortably.

Focus on Timing, Spacing, and Depth

Planting garlic is a bit like laying the groundwork for a good story: timing and structure matter. We always plant in the fall—October or early November—before the ground freezes but after the temperatures cool. It gives the cloves time to send out roots without sprouting too early.

When we plant, we space the cloves about 6 to 8 inches apart in rows that are 12 to 18 inches apart. That elbow room really lets the bulbs expand. We plant each clove about 2 to 4 inches deep, pointed end up. This gives the roots time to anchor down before winter.

Too shallow, and they heave out of the ground with the first frost. Too deep, and they struggle. Like most things in gardening, it’s a balance.

Garlic Cultivation Techniques that Work

Big garlic bulbs don’t just happen. It takes a little strategy and a bit of care through the seasons. Let’s walk through the real workhorses of garlic growing.

We always mulch after planting. Straw works well. It keeps the soil moist, suppresses weeds, and protects against temperature swings. When it comes to watering, we aim for about an inch a week—sometimes more in dry spells. Consistency is key. Letting the soil dry out can stunt growth.

Weeds? Treat them like the competition they are. Pull them regularly, but gently. Garlic roots sit close to the surface, and they don’t take kindly to being disturbed.

As for pests—aphids, thrips, and onion maggots are the usual culprits. We monitor regularly and act fast with organic methods. Garlic may be hardy, but it doesn’t like being chewed on.

Watering and Fertilizing Garlic Plants

We stick to a deep, consistent watering routine—usually once or twice a week, depending on rainfall. You want moisture to reach the roots, but you don’t want soggy leaves, which invite disease. Think of it as a balancing act between hydration and hygiene.

In early spring, when the shoots are pushing through, we apply a slow-release fertilizer. Nothing too heavy. Garlic doesn’t need to be pampered—just supported. Every 4 to 6 weeks, we’ll supplement with a liquid feed to keep growth on track.

Pro tip: don’t overdo it. Too much nitrogen leads to lush leaves and lackluster bulbs. We learned that the hard way once or twice.

Harvesting and Curing for Long-Term Storage

The moment of truth comes when those green garlic tops start to fade—usually mid to late summer. We wait until the bottom leaves are dry and yellow, but the upper leaves are still green. Then it’s time to harvest.

We use a garden fork, never a shovel, and we’re gentle. Garlic bruises easily, and bruised bulbs won’t last. Once pulled, we brush off excess soil (no washing!) and hang them in a shaded, breezy spot. Think barn rafters, garage shelves, or anywhere with decent airflow. We leave them for about 2 to 4 weeks.

After curing, we trim the roots and cut back the stalks—unless we’re braiding softneck varieties. Then we store the bulbs in mesh bags or open crates in a cool, dry place. Between 50 and 70°F works best. Too humid, and they mold. Too dry, and they shrivel.

Wrapping It Up

If you’ve made it this far, you’re well on your way to growing garlic that makes your garden proud and your kitchen sing. We grow garlic not just because it’s useful, but because it’s deeply satisfying. Each step—from prepping the soil to storing the final bulbs—brings its own rhythm and reward.

Garlic doesn’t ask for much, but it rewards you for paying attention. With the right variety, good soil, careful planting, and consistent care, you can grow garlic that’s big, bold, and bursting with flavor.

And let’s be honest—there’s nothing quite like cooking with garlic you pulled from the ground yourself.
