You don't root garlic bulbs; you root garlic cloves which then grow into garlic bulbs. Here's how to do it:
The process of "rooting garlic" actually involves planting individual garlic cloves, which then develop roots and grow into full garlic bulbs. Follow these steps for successful planting:
-
Select Healthy Cloves: Choose large, healthy cloves from a garlic bulb. These will have the best chance of producing a robust plant.
-
Prepare the Soil: Ensure the soil is well-draining and rich in organic matter. Amend with compost if necessary.
-
Plant the Cloves:
- Orientation: Place the flat, wider, rooting end of the clove down into the soil. The pointy end should face upwards.
- Depth: Plant cloves 1 to 2 inches deep in warmer climates or 3 to 4 inches deep in colder climates.
- Spacing: Space cloves about 6 inches apart within rows, with rows spaced about 10 to 12 inches apart.
-
Water Thoroughly: Water the newly planted cloves well.
-
Mulch (Especially for Fall Plantings): Add a 4- to 6-inch layer of weed-free mulch, such as straw, leaves, or grass clippings. This helps retain moisture, suppress weeds, and protect the cloves during winter.
-
Timing: Garlic is typically planted in the fall for a summer harvest. In warmer climates, planting can also occur in early spring.
By following these steps, you'll ensure your garlic cloves develop roots and grow into healthy garlic bulbs.
