Plant individual garlic cloves about 2 inches (5 cm) deep from the top of the clove to the soil surface, then cover with mulch if you’re in a cold-winter area.

Quick Scoop

  • Ideal depth in most home gardens:
    • 1.5–2.5 inches of soil above the top of each clove.
  • If you won’t mulch or you have very cold winters, you can go a bit deeper (up to about 3 inches of soil over the clove) to protect from freeze–thaw heaving.
  • In milder climates or containers, shallower planting (around the clove’s own height deep) works well, as long as drainage is good.

Why Depth Matters

  • Planting too shallow can let cloves heave out of the soil over winter and dry out or freeze.
  • Planting extremely deep can delay emergence and may slightly reduce vigor if soil is heavy or poorly drained.

Simple Step‑by‑Step

  1. Break the bulb into individual cloves just before planting.
  1. Make holes so that, once filled, the top of each clove will sit about 2 inches below the soil surface.
  1. Place cloves pointy side up, flat root end down.
  1. Cover with soil, firm gently, then add 3–6 inches of straw or leaves in cold climates.

Adjusting for Your Conditions

  • Very cold winters, windy/open sites, or no snow cover:
    • Aim for the deeper end (around 2.5–3 inches of soil above the clove) plus a good mulch layer.
  • Mild winters or garlic in pots/raised beds with fast drainage:
    • 1–2 inches of soil above the clove is usually enough.
