Light requirements: Full sun (6 hours or more) is ideal.
Planting: Space 4 to 12 inches apart, depending on variety.
Soil requirements: Plants grow best in well-drained, fertile soil rich with organic matter.
Water requirements: Keep soil consistently moist.
Frost-fighting plan: Tolerates only light frosts. Protect young plants with a frost cloth.
Common issues: Watch for (and remove) parsleyworms.
Harvesting: Harvest leaves as desired during growing season, never taking more than one-third of the leaves. When the bulb reaches 4 inches across, it’s time to harvest it.
Storage: Refrigerate unwashed bulb and use within 3 to 5 days.
