Dormancy & Root Development
8-10 weeksCloves planted in fall (October-November) develop roots through winter while bulb remains dormant underground

Vegetative Growth
8-12 weeksPlant produces 5-8 leaves, increasing in height and leaf size; stem thickens and begins to elongate
Maintain consistent watering; provide nitrogen-rich fertilizer; monitor for pests; remove any flower scapes that appear (to direct energy to bulb)
Bulb Development & Maturation
6-8 weeksBulb begins swelling underground as leaves continue growing; cloves become distinct and plump
Reduce watering frequency as June approaches; cease nitrogen fertilizing; mulch helps regulate soil moisture and temperature
Harvest Readiness
2-3 weeksLower leaves begin yellowing and drying; bulb reaches full size with papery outer skins; plant begins to senesce
Stop watering 2 weeks before harvest; watch for 50% of leaves to turn brown; harvest when soil is dry for better storage

Harvest Tips
Harvest in June-July when 50% of the top leaves have turned brown and dried. Gently loosen soil with a fork and pull by hand when soil is dry. Cure in a warm, dry, airy location (75-80°F) for 2-3 weeks until necks are completely dry and papery. Store in a cool (50-60°F), dry place with good air circulation for up to 6+ months. Choose larger, fully mature bulbs for replanting next season.
Fun Facts
- 🌱 Ajo Blanco is a traditional Spanish softneck garlic variety that has been cultivated in Spain for centuries and is deeply embedded in regional culinary tradition.
- 🌱 Unlike hardneck varieties, softneck garlic like Ajo Blanco produces no central scape (flowering stem), directing all energy into bulb development, which is why it grows larger and stores longer.
- 🌱 Ajo Blanco cloves remain notably milder and sweeter after curing than most other garlic varieties, making it prized by chefs who prefer subtle garlic notes in dishes.
