Light requirements: Partial shade.
Planting: Space 8 to 12 inches apart.
Soil requirements: Plants thrive in rich, moist but well-drained soil with a pH of 6.2 to 6.8. Work organic matter into soil before planting to add fertility and improve moisture retention. In containers, use premium quality potting soil.
Water requirements: Keep soil consistently moist. Apply mulch to keep soil cool and leaves clean. The combination of cool and moist soil postpones flowering and helps plants produce leafy growth longer.
Frost-fighting plan: Culantro is extremely cold-sensitive. Light frosts (28º F to 32º F) can damage plants. Do not set plants out before your area’s last frost date. Use a frost blanket to protect newly planted seedlings from late spring frosts.
Growing tip: Once plants flower, leaf flavor and texture becomes undesirable. To prolong your harvest, clip flower stems as soon as you see them.
Harvesting: Pick leaves frequently and early in the growing season, before plants flowers. Pinch or pull individual leaves when picking, and be sure to never harvest more than one-third of the plant.
Storage: Wrap leaves in a barely damp paper towel and tuck into a loosely closed plastic bag or container. Store in the refrigerator and use within 7 to 10 days.
