Harvest Tips
Harvest flower buds 3-5 years after planting when they reach full length (approximately 1.25 inches) but before opening into flowers. Pick clusters by hand or with pruning shears in the morning after dew dries. The buds should be firm and not yet showing flower petals. Dry immediately on screens in full sun for 3-5 days, turning occasionally, until the stem snaps cleanly and buds are dark reddish-brown. Store dried cloves in airtight containers away from light and heat; they maintain peak flavor for 6-12 months.
