What is the standard spacing for garlic?

Most gardeners plant cloves 6 inches (15 cm) apart within the row and leave 12 inches (30 cm) between rows. Tighter 4-inch spacing is used for smaller softneck varieties; wider 8-inch spacing suits large hardneck varieties like Elephant garlic.

How deep should garlic cloves be planted?

Plant cloves 2 inches (5 cm) deep in mild climates and 3–4 inches (7.5–10 cm) deep in cold climates where the ground freezes hard. Deeper planting gives more frost protection.

How many cloves are in a seed bulb?

Softneck varieties typically have 8–16 cloves per bulb; hardneck varieties have 4–10. The default in this calculator is 8, which works for most common varieties. Adjust it to match your specific seed garlic.

Why does the calculator round up clove and bulb counts?

Partial cloves cannot be planted, and partial bulbs must still be purchased whole. Rounding up ensures you buy enough seed garlic and always have a few spares in case of sprouting or damage.

Does spacing affect garlic bulb size?

Yes. Wider spacing generally produces larger bulbs because each plant has more soil volume and nutrients. Closer spacing yields more plants per area but smaller individual bulbs.

When is the best time to plant garlic?

In most temperate climates, garlic is planted in fall (October–November) about 6 weeks before the ground freezes. This allows roots to establish before winter. Spring planting is possible but usually yields smaller bulbs.
