Clove Establishment
2-3 weeks post-plantingIndividual cloves develop roots and first shoots emerge from soil. Small green shoots visible above ground.
Ensure adequate moisture and mulch heavily (3-4 inches) to protect from frost and regulate soil temperature. No fertilizer needed yet.
Vegetative Growth
January-March (in Northern hemisphere)Multiple leaves emerge and plant develops a root system. Visible foliage reaches 4-8 inches tall by spring.
Apply balanced fertilizer (10-10-10) in early spring when new growth resumes. Water consistently. Remove any diseased leaves.
Stem & Scape Development
3-4 weeks in springHardneck variety produces a flowering scape (central stem) that curls. Scape emerges from center of plant.
Remove scapes 1-2 inches above leaf line when they first curl (April-May). This redirects energy to bulb. Compost or use scapes for cooking.
Bulb Maturation
4-6 weeks (May-early June)Underground bulb expands and cloves enlarge. Leaves begin to yellow and dry from tips downward. Papery wrapper forms on bulb.
Stop watering 2-3 weeks before harvest. No additional fertilizer. Reduce water to encourage bulb curing.
Harvest Ready
Early to mid-June (harvest window is 1-2 weeks)Lower 2-3 leaves completely brown/dry. Bulb skin becomes papery and white. Bulb easily pulls from soil.
Harvest when 25-50% of foliage has dried. Cure in warm, dry, well-ventilated location for 2-3 weeks before storage.
