Harvest
Porophyllum ruderale, commonly known as 'Bolivian coriander' or 'Papalo', should be harvested when the plant reaches about 12-18 inches in height, typically around 60 days after planting. Harvesting is best done in the morning when the essential oils are most concentrated. Use sharp scissors or pruning shears to cut the stems just above a leaf node to encourage further growth. Ensure to leave some foliage on the plant to allow for continued growth and potential multiple harvests throughout the growing season. The leaves can be used fresh or dried for later use.
Soil
This plant prefers well-draining loamy soil. It can tolerate a range of soil types but performs best in nutrient-rich, slightly acidic to neutral soil. Ensure good drainage to prevent root rot.
