How to grow garlic, step by step
- 1
Prepare soil to the crop’s needs
Test and prepare your soil to match garlic's requirement: Well-drained, fertile loam, pH 6.0–7.5; high organic matter; avoid compaction. Correct pH and add organic matter before planting.
- 2
Plant in the right window
Plant during the recommended season: Armenia: October–November planting (overwintering), June–July harvest. Use certified seed or healthy planting material to avoid carrying over disease.
- 3
Irrigate to target
Supply 400–600 mm; less water in spring when bulbing; irrigate moderately. Even, well-timed moisture during the critical growth stages drives yield and quality.

Scout and protect against disease
Watch for White rot (Sclerotium cepivorum) and Downy mildew. Rotate crops, keep good spacing for airflow, and act early — AI disease-scan apps can warn you days before damage is visible.
- 5
Harvest at the right time
Harvest after 8–9 months from planting (autumn-planted). Handle gently and cool quickly to cut post-harvest losses, which can otherwise reach 20–40%.
