Garlic From the Ground Up
Your Guide to Planting, Harvesting, and Making the Most of Every Bulb
Garlic is one of those things that earns its place in every corner of a well-run home. It grows easily, stores for months, heals from the inside out, and makes nearly everything you cook taste better. Once you start growing your own, buying the papery pale bulbs from the grocery store feels like a downgrade.
This post covers all of it — how to plant and harvest, what the research says about its health benefits, and the recipes I come back to every season. The growing guide and health section are free. The recipes — including a roasted garlic spread, a simple weeknight pasta, and my favorite garlic-forward chicken — are behind the paywall for paid subscribers.
Let’s start at the beginning: in the ground.
How to Grow Garlic
Garlic is one of the most rewarding crops you can grow, and one of the most forgiving. It goes in the ground in fall, winters over quietly, and comes up strong in spring. By midsummer, you’re pulling bulbs that look nothing like anything sold in a store.
When to plant In Minnesota and most of the upper Midwest, plant garlic in October — after the first frost but before the ground freezes hard. You want the cloves to establish roots before winter sets in, but you don’t want tops growing tall before the cold arrives.
What to buy Start with seed garlic from a local farm or reputable seed company rather than grocery store bulbs, which are often treated to prevent sprouting. Choose hardneck varieties for northern climates — Rocambole and German Red are both excellent. Hardneck garlic has a richer, more complex flavor than the softneck varieties you find in most stores.
How to plant Break bulbs into individual cloves just before planting. Plant each clove pointed end up, about 2 inches deep and 6 inches apart. Cover with a few inches of straw or shredded leaves to insulate through winter.
What to do in spring Remove mulch once you see green shoots emerging. Water consistently but don’t overwater — garlic doesn’t like wet feet. In June, you’ll notice scapes: the curly green shoots that hardneck varieties send up. Cut them off. This redirects the plant’s energy into bulb development, and scapes are entirely edible — use them in the recipes below.
When to harvest Harvest when the lower leaves begin to brown and dry, typically mid-July. Don’t wait until all the leaves are gone. Pull bulbs gently, brush off loose soil, and cure them in a cool, dry place with good airflow for three to four weeks. Properly cured garlic stores for six months or more.
What goes wrong The most common mistake is planting too late or too shallow. Cloves planted after the ground is nearly frozen won’t establish roots and won’t perform well. Plant on the earlier end of your window.
More Than Flavor: What It Supports
Garlic has a long history in traditional medicine, and there’s solid research behind some of its most well-known benefits.
Cardiovascular support Multiple studies support garlic’s role in reducing blood pressure and improving cholesterol profiles. The active compound allicin — released when garlic is crushed or chopped — has been shown to relax blood vessels and reduce arterial stiffness.
Immune function Garlic has well-documented antimicrobial and antiviral properties. A 2016 study published in the Journal of Nutrition found that aged garlic extract reduced the severity and duration of cold and flu symptoms in healthy adults.
Anti-inflammatory properties Chronic inflammation underlies many of the most serious health conditions we face. Garlic contains sulfur compounds that inhibit inflammatory pathways, making it a useful food-as-medicine addition to an anti-inflammatory diet.
Blood sugar regulation Research suggests that garlic may improve insulin sensitivity and help regulate blood sugar levels, which is relevant for anyone managing or looking to prevent type 2 diabetes.
How to get the most out of it Crush or chop garlic and let it rest for five to ten minutes before cooking. This activates allicin. High heat applied too quickly destroys it. Raw garlic has the highest potency; lightly cooked is next.
