For most gardeners, the simplest and most dependable way to propagate garlic is to separate a healthy bulb into cloves and plant them. Some garlic varieties can also be grown from bulbils produced on a scape; growing garlic from true botanical seed is possible in some lines, but uncommon and specialized.
How do you propagate garlic?
Garlic can be propagated in three ways: by planting cloves, by planting bulbils from certain varieties, or, less commonly, by growing true botanical seed. Cloves are the usual choice for home gardens: each planted clove can form a new bulb. The best method depends on what planting material you have and whether you want a predictable clone or genetic diversity.

| Method | How available is it? | Time to a full bulb | Genetic outcome |
|---|---|---|---|
| Cloves | Widely available from healthy planting bulbs | The most direct, familiar route | Preserves the parent variety vegetatively |
| Bulbils | Only available from garlic types that form bulbils on scapes | Takes longer; bulbils may first form small, unsegmented rounds | Clones the parent plant |
| True botanical seed | Rare; possible in some garlic lines | Specialized and less predictable; no general home-garden timeline is established by the cited extension guidance | Can introduce genetic diversity |
1. Plant individual cloves
Choose healthy planting stock
Start with a healthy garlic bulb intended for planting, often sold as a “seed bulb” or “seed garlic.” These terms mean planting stock, not botanical seed. Separate the bulb into individual cloves close to planting time, and plant the cloves individually. Choose healthy, larger cloves when possible: extension guidance says larger planting cloves tend to produce larger mature bulbs.

#1 Best Overall
- Large, Firm Garlic Cloves for Planting. Each bulb produces thick, well-formed garlic cloves that separate cleanly. Customers consistently mention the firm texture and size, making these garlic seeds for planting easy to handle and space evenly.
- Cold Hardy Hardneck Variety. These hardneck garlic bulbs for planting are well suited for fall planting in colder regions. Growers in northern climates report reliable overwintering and strong spring emergence.
- Fast Sprouting and Healthy Growth. Planted garlic seeds sprout quickly under proper conditions, producing uniform shoots. Suitable for raised beds, backyard gardens, or container planting with consistent early growth.
- Dual Use for Garden and Kitchen. Plant the largest garlic cloves for planting and enjoy extra cloves for everyday cooking. Many buyers appreciate the bold aroma and flavor that develops as bulbs mature.
- Clean Packaging and Predictable Yield. Each 5 pack includes whole garlic bulbs selected for planting use. Bulbs typically yield multiple plantable cloves, helping gardeners plan spacing, depth, and seasonal harvest expectations.
Plant for your region
Planting calendar, depth, spacing, and winter care vary by region, so follow your local cooperative extension service’s guidance rather than treating one set of measurements as universal. For example, University of Georgia guidance gives a depth of 1–3 inches and spacing of 6 inches, while Iowa State provides different region-specific dimensions. New Mexico State University Cooperative Extension Service notes that each planted clove will produce a bulb with 5 to 16 cloves, with bulb size and clove count varying by variety; that range is not a guarantee for every plant or region.
2. Grow garlic from bulbils
Collect bulbils from a scape
Some hardneck or top-setting garlic varieties form a scape—a flowering stalk—with a cluster of small bulbils at its tip. Not all garlic types produce them. If you want bulbils for propagation, leave some scapes on the plants and collect the bulbils when they are ready to plant.
Rank #2
- Bold Flavor: Enjoy the rich, spicy taste that garlic is renowned for—perfect for enhancing your culinary creations.
- Cold Hardy: These garlic seeds thrive in cooler climates and can withstand harsh winter conditions.
- Large Cloves: Easy to peel and plant, yielding an abundant harvest of sizeable garlic cloves.
- Homegrown Quality: Grown with care to ensure you receive premium quality garlic seeds.
- Versatile: Ideal for home gardeners, food enthusiasts, and garlic lovers seeking a reliable and flavorful crop.
Gardeners seeking to maximize the underground bulb harvest are generally advised to remove scapes. Leaving selected scapes is the trade-off when you want bulbils for planting instead.
Expect an extra growing stage
Plant bulbils as small propagules. They may first grow into small, unsegmented bulbs known as rounds. If left in the ground to continue growing, they can later form a cluster of cloves. Bulbil propagation can increase planting stock and produces clones of the parent plant, but it generally takes longer to reach a full-sized bulb than starting with cloves.
Rank #3

3. Grow garlic from true botanical seed
Garlic is generally propagated vegetatively and rarely produces fertile botanical seed. Some subtypes can be coaxed to produce true seed under suitable conditions. Unlike cloves and bulbils, true seed can introduce genetic diversity rather than simply multiplying a selected plant.
This is a specialized option, not the ordinary home-garden method. The cited extension guidance does not provide a general protocol for producing garlic seed at home, so gardeners interested in it should seek guidance specific to the garlic line and growing conditions.
Quick Recap
Which propagation method should you choose?
- Choose cloves for the most accessible and dependable route to a new garlic bulb.
- Choose bulbils if your garlic produces them and you are willing to wait through an additional growing stage to multiply the variety.
- Consider true seed only if you have access to a seed-producing line and want to explore a less predictable method that can add genetic diversity.
