How To Grow Garlic
You don’t need a farm. You don’t need fancy soil. You don’t even need experience.
With about $5 and 10 minutes, you can plant garlic this fall and harvest big, flavorful bulbs next summer. That’s it.
In this episode of Organic Matters, Shameem and Emma break down exactly how to do it — and the 7 mistakes that keep most people from getting big bulbs.
Why Fall Is Non-Negotiable
Garlic is a fall crop. It needs winter chill to split into big cloves.
Plant in spring, and you’ll get tiny, single-clove bulbs. Plant in fall, and winter does most of the work for you.
Rule of thumb: Plant 2-4 weeks before your ground freezes solid. For most gardeners, that’s October to mid-November.
The 7 Mistakes Most People Make
- Planting in Spring
Garlic needs cold to trigger bulbing. Spring planting skips that step entirely. If you missed fall, you can still plant in early spring, but expect smaller bulbs.

- Planting Grocery-Store Garlic
Grocery garlic is often treated to prevent sprouting, and it’s rarely adapted to your climate.
Instead, buy seed garlic from a local farm or garden center. Break the bulb apart and plant only the biggest, fattest outer cloves. Eat the small inner ones — they make great garlic butter tonight.
- Planting Upside Down
This one is embarrassingly common.
Pointy end UP, flat root end DOWN. The flat end is where roots grow. Flip it, and your garlic will struggle to emerge.
- Planting Too Shallow, Too Deep, or Too Crowded
Think finger-deep.
Push each clove about 2 inches deep (about one knuckle + a bit), and space them 6 inches apart in rows 10-12 inches apart. Crowded garlic competes for nutrients and stays small.
- Overwatering
Garlic hates wet feet.
Water once well after planting in fall to settle them in. Then leave them alone for winter. In spring, water lightly only when the top inch of soil is dry. Once leaves start to yellow in early summer, stop watering completely.
Wet soil = rot.
- Skipping Mulch
This is the lazy genius secret.
Add 3-4 inches of straw, shredded leaves, or wood chips right after planting. Mulch keeps garlic warm in winter, cool in summer, holds moisture, and smothers weeds so you barely have to do anything until harvest.
- Pulling Too Early
Patience pays.
Wait until about half the leaves (4-5 leaves) are yellow and falling over. That’s your signal. Dig one bulb up to check — if the wrapper is tight and the cloves are plump, it’s time.
Pull too early, and your bulbs won’t store well. Pull too late, and they split open in the ground.
Don’t Throw Away Scapes!
If you grow hardneck garlic, you’ll get curly flower stalks in late spring called scapes.
Snap them off when they make one full curl. Why?
Your plant puts energy into the bulb instead of the flower, so you get bigger bulbs.
You get a bonus harvest.
Scapes taste like mild garlic with a fresh, green bite. Blend them into pesto, chop into scrambled eggs, or whip into garlic-scape butter.
Growing Garlic in Pots?
No garden bed? No problem.
Use a pot at least 12 inches deep with drainage holes. Fill with regular potting mix + a handful of compost. Plant cloves 4 inches apart, mulch the top, and place the pot where it gets full sun.
Pots dry out faster, so check water in spring, but otherwise the rules are the same.
Fixing Bad Soil
Clay soil: Mix in compost and a little sand to loosen it up. Never plant in soggy, compacted clay — garlic will rot.
Sandy soil: Mix in lots of compost or aged manure to help it hold moisture and nutrients.
Garlic isn’t picky, it just wants loose soil that drains well.
How to Cure and Store It
Don’t eat it all fresh. Cured garlic lasts for months.
After harvest, shake off loose dirt — don’t wash it.
Lay bulbs in a single layer in a shady, airy spot for 2 weeks.
Once the wrappers are papery and necks are dry, trim roots and cut the stalk to about 1 inch.
Store in a cool, dry, airy spot — a mesh bag or basket in a pantry works perfectly.
Not the fridge. Cold, humid fridge air makes garlic sprout and go soft.
Your 10-Minute Checklist
Buy seed garlic — $5 gets you 2-3 bulbs
Break into cloves, keep the biggest ones
Plant pointy-end up, 2″ deep, 6″ apart
Water once
Mulch 3-4″ with straw or leaves
Walk away until spring
That’s the lazy genius way. Fall does the work, you get the harvest.
