Garlic Planting Calculator — Cloves, Spacing & Timing
Calculate garlic clove quantities, spacing, and planting depth.
How We Calculate This
Cloves per row = Row length / Spacing. Total cloves = Cloves per row x Rows. Bulbs to order = Total cloves / Cloves per bulb.
Yield assumes a 90% success rate, which is typical for autumn-planted garlic in good conditions.
Spacings: Softneck 10cm, Hardneck 15cm, Elephant 20cm, all with 30cm between rows.
