You might think our short growing season makes it impossible, but planting garlic in Alaska is actually one of the easiest and most rewarding things you can do in your garden. While other plants are shivering and dying off at the end of the season, garlic is just getting started. It's a bit counterintuitive—you're basically putting a seed in the ground right before the world freezes solid—but that cold period is exactly what garlic needs to develop those big, flavorful cloves we all love.
If you've never tried it before, don't worry. You don't need a degree in botany or a heated greenhouse. You just need a little bit of timing, the right variety, and a heavy blanket of mulch to see it through the winter.
Picking the Right Garlic for the North
The first thing you need to know is that not all garlic is created equal. If you grab a bulb from the grocery store and stick it in the ground, you're probably going to be disappointed. Most store-bought garlic is a "softneck" variety grown in California or China. It likes mild winters and long, warm springs. In Alaska, that garlic usually just rots or gives up the ghost by February.
For our climate, you want hardneck garlic. These varieties are much tougher and are actually closer relatives to wild garlic. They produce a stiff central stalk (the "scape") and are built to handle a deep freeze. Some of the best performers in Alaska are varieties like Music, German Red, and Siberian. The Siberian variety, in particular, is a beast—it thrives in the cold and produces huge cloves with a nice, spicy kick.
Getting the Timing Right
Timing is everything when you're planting garlic in Alaska. You want to get the cloves in the ground late enough that they don't start growing a foot of green top-growth before the snow flies, but early enough that they can establish some roots.
For most of us in the Southcentral or Interior regions, the sweet spot is usually between late September and mid-October. A good rule of thumb is to aim for about two to four weeks before the ground freezes solid. If you're in Southeast Alaska, you might be able to push it into late October or even November because of the milder maritime climate. You're looking for that window where the air is crisp, the mosquitoes are finally dead, and you're starting to think about pulling the winter parkas out of storage.
Preparing Your Garden Bed
Garlic hates "wet feet." If you plant it in a low spot where water pools during the spring thaw, your cloves will just turn into mush. Choose a spot with well-draining soil and as much sun as possible.
Before you plant, it's a great idea to work some compost or well-rotted manure into the soil. Garlic is a heavy feeder, meaning it wants plenty of nutrients to build those big bulbs. I usually throw in a little bit of bone meal or a balanced organic fertilizer too. Since the garlic is going to be sitting in that one spot for the next nine months, you want to make sure the "pantry" is well-stocked for when it wakes up in the spring.
The Actual Planting Process
When you're ready to plant, take your garlic bulbs and carefully break them apart into individual cloves. Leave the papery skin on each clove—it's like a little protective jacket. You want to pick the biggest, healthiest-looking cloves for planting. The bigger the clove you plant, the bigger the bulb you'll harvest next summer. Save the tiny inner cloves for your dinner tonight.
- Dig a hole or a trench: In Alaska, we plant a bit deeper than they do down south to protect against the extreme cold. Aim for about 4 to 6 inches deep.
- Pointy side up: This is the most important part! The flat end is where the roots grow, and the pointy end is where the sprout comes out. If you plant it upside down, it'll still grow, but it'll be a twisted, weird-looking mess.
- Spacing: Give them some elbow room. Space your cloves about 6 inches apart. If you're doing multiple rows, keep the rows about a foot apart so you have room to weed later.
- Cover them up: Fill the holes back in with soil and pat it down gently.
The Magic of Mulch
If there is one "secret" to successfully planting garlic in Alaska, it's mulch. Because our temperatures can drop to -20°F or lower without a moment's notice, you need to insulate the ground.
Once your cloves are tucked in, cover the entire bed with 4 to 6 inches of straw, dried leaves, or even grass clippings (as long as they aren't full of weed seeds). This layer of mulch acts like a thermal blanket. It keeps the ground temperature stable and prevents the "freeze-thaw" cycle that can heave the cloves right out of the dirt. If we get a good snowpack, that's even better—snow is the best insulator there is.
Spring Wake-up and Summer Care
When the snow finally melts and the ground starts to warm up in late April or May, you'll start to see little green shoots poking through the mulch. It's one of the most exciting sights for an Alaskan gardener because it's the first real sign that spring is actually happening.
Don't be in a rush to pull the mulch away. It'll help keep the weeds down and hold moisture in the soil. As the weather warms up, make sure the garlic stays watered. If the soil gets bone-dry, the bulbs won't grow very big.
In June, your hardneck garlic will start to grow a curly, leafless stalk called a scape. You want to cut these off once they've done a loop or two. Removing the scape forces the plant to put all its energy into the bulb underground rather than trying to make seeds. Plus, scapes are delicious! They taste like a mild, crunchy garlic and are amazing grilled or turned into pesto.
Harvesting and Curing
By late July or early August, the bottom leaves of your garlic plants will start to turn brown. When the bottom two or three leaves are dead but the top ones are still green, it's go-time.
Carefully loosen the soil with a garden fork—don't just grab the stem and pull, or you might snap it off. Lift the bulbs out of the ground and gently shake off the dirt.
Now comes the part that requires patience: curing. You need to let the garlic dry out so it stores well. Hang it in bundles or spread it out in a dry, shady spot with good airflow (like a porch or a shed) for about 2 to 4 weeks. Once the outer skins are papery and the roots are brittle, you can trim the stalks and store the bulbs in a cool, dry place.
Why It's Worth the Effort
Planting garlic in Alaska is a bit of a long game, but the flavor of homegrown garlic is lightyears beyond anything you'll find at the supermarket. It's sharper, fresher, and has a complexity that just disappears when garlic is shipped halfway across the world.
Plus, there's something incredibly satisfying about standing in your garden in October, the wind biting at your ears, knowing that while you're inside drinking cocoa all winter, your garden is silently working away beneath the snow. When you harvest those heavy, pungent bulbs next summer, you'll be glad you took the time to get them in the ground. Happy planting!
