Growing Garlic Bought at the Grocery Store: A Beginner’s Guide to Planting, Care, and Harvest

If you’ve ever stared at a bulb of garlic on your kitchen counter and wondered if you could plant it—good news: growing garlic bought at the grocery store is not only possible, it’s surprisingly easy and rewarding! Whether you have a full garden, a few flower pots, or just a sunny patch in your backyard, you can grow flavorful, homegrown garlic right from the cloves you buy at your local supermarket.

This guide will walk you through everything you need to know about growing garlic, from when to plant it to how to care for it—and why using store-bought garlic can be a perfectly viable (and budget-friendly) option.

When Should You Plant Garlic?

Timing is key when it comes to growing garlic successfully. Garlic is typically planted in the fall and harvested in late spring or early summer.

In warmer climates like Texas, the ideal window for planting is late October through February. If your garlic experiences a few freezes, it will result in larger, more robust bulbs. On the other hand, planting garlic during a warmer winter might yield lots of leafy growth but smaller bulbs underground. Cold exposure, known as vernalization, encourages the garlic to divide into cloves and form full bulbs.

No matter your location, the goal is to get garlic in the ground several weeks before the ground freezes in colder zones—or before the warm season begins in milder climates.

Can You Really Grow Garlic from the Grocery Store?

Yes! One of the easiest and most affordable ways to start growing garlic is by using bulbs from your local grocery store. Here’s what to know:

• Choose organic garlic whenever possible. Conventional store-bought garlic is often treated with chemicals that prevent sprouting, while organic garlic is more likely to grow successfully.

• Be aware of your growing zone. Some garlic varieties sold in stores may not be ideal for your climate. If you’re looking for specialty varieties or ones suited for specific zones, consider buying certified seed garlic online.

• Avoid garlic that looks moldy, soft, or discolored. Choose healthy, firm bulbs with tight, papery skins.

Still, growing garlic bought at the grocery store is a great entry point for new gardeners—and a perfect experiment for those who want to learn more about the plant before committing to more expensive seed garlic.

Step 1: Break the Bulb into Cloves

Once you’ve brought your garlic bulb home, you’ll need to break it apart. Gently separate the bulb into individual cloves, leaving the papery skin intact. This skin protects the clove during germination.

Each clove you plant will grow into a new bulb of garlic. That’s the magic of this humble allium!

Step 2: Prepare the Planting Area

Garlic needs full sun and loose, well-draining soil to thrive. Whether you’re planting in a raised bed, a garden row, or even a container, be sure the soil is:

• Free of weeds, so your garlic doesn’t compete for nutrients

• Loose and fluffy, to allow bulbs to expand

• Rich in organic matter like compost or aged manure

If your soil is heavy clay or too compacted, work in compost and sand to loosen it up. Adding mulch after planting will help suppress weeds and retain soil moisture.

Step 3: Planting the Garlic Cloves

Now for the fun part—planting!

1. Take each clove and plant it pointy-end up, with the flat root end facing down.
2. Set the clove about 1–2 inches deep into the soil.
3. Space each clove at least 6 inches apart to give them enough room to grow into full bulbs. If planting Elephant Garlic, go even wider—8 to 10 inches apart is better.

After planting, gently cover the cloves with soil and pat it down lightly. If you expect frost, a layer of mulch like straw, leaves, or pine needles can help insulate the young shoots.

Caring for Your Garlic Plants

Once planted, garlic doesn’t require much maintenance, but a few steps will help ensure a healthy harvest:

• Watering: Keep the soil lightly moist but not soggy. Garlic doesn’t like to sit in water, so good drainage is essential.

• Weed control: Garlic doesn’t compete well with weeds, so check your beds regularly.

• Fertilizing: You can feed your garlic with a nitrogen-rich fertilizer in early spring as it starts to grow more actively. Fish emulsion or compost tea are great natural options.

If you’re growing garlic bought at the grocery store in containers, make sure they get full sun for 6-8 hours a day and have adequate drainage holes.

When to Harvest Garlic

Garlic is typically ready to harvest about 8 to 9 months after planting, depending on the variety and your local climate.

You’ll know it’s harvest time when:

• The bottom 3 or 4 leaves turn brown, while the top ones remain green.

• The garlic stalks start to fall over slightly.

Use a garden fork to gently lift the bulbs from the soil—don’t pull them out by the leaves, as that can damage the bulb.

Curing and Storing Your Garlic

After harvesting, garlic needs to cure before storing:

1. Brush off excess dirt (don’t wash it).
2. Bundle a few stalks together and hang them in a dry, well-ventilated place out of direct sunlight.
3. Let them cure for 2 to 3 weeks, until the skins are papery and the stems are dry.

Once cured, trim the roots and stalks, and store the garlic in a cool, dark, dry place. Properly cured garlic can last for several months and even be used for your next planting season.

Final Thoughts: A Simple Path to Homegrown Garlic

Growing garlic bought at the grocery store is one of the most satisfying beginner garden projects you can try. It’s low-risk, low-cost, and incredibly rewarding. Even if you don’t get perfect results on your first try, you’ll learn valuable lessons about soil, timing, and plant care—all while getting your hands a little dirty.

So next time you’re picking up groceries, grab an extra bulb of organic garlic and give it a try. Your garden—and your dinner plate—will thank you!
