Planting Guide · December 2025 · 5 min read
Garlic planting is one of the most rewarding fall garden tasks, and proper timing and technique make the difference between small cloves and large, well-formed bulbs. Whether you grow hardneck or softneck varieties, understanding planting depth, spacing, and mulching ensures a successful harvest the following summer. Fall-planted garlic develops strong root systems before winter dormancy and emerges vigorously in spring.
Hardneck garlic produces a stiff central stalk called a scape, develops fewer but larger cloves, and performs best in cold climates with reliable winters. Popular hardneck types include Rocambole, Porcelain, and Purple Stripe. Softneck garlic has a flexible neck ideal for braiding, stores longer, and thrives in milder climates.
Plant individual cloves 2 inches deep with the pointed end facing up. Space cloves 6 inches apart in rows that are 12 inches apart. Break bulbs into individual cloves no more than 48 hours before planting to prevent drying out. Always plant the largest cloves for the biggest bulbs at harvest.
In very cold regions (zones 3-4), plant slightly deeper at 3 inches to protect against frost heaving. Ensure the soil is well-drained, as garlic will rot in waterlogged conditions.
Apply 4-6 inches of straw mulch after planting to insulate cloves, suppress weeds, and maintain even soil moisture. In northern regions, apply mulch after the first hard frost to prevent premature sprouting. Leave mulch in place through spring; garlic shoots will push right through it.

This simple step can increase bulb size by 20-30%. Harvest garlic when the lower third of leaves have browned but the upper leaves remain green, typically in mid to late July.
