Cilantro Santo is bred to be slow bolting. Direct sow short rows of these frost-tolerant plants every other week from spring to late summer for continuous harvest. The mature seeds, better known as coriander, are easy to harvest, and used in many dishes. As soon as a central stem appears and the uppermost leaves become frilly, it’s time to harvest the whole plant, roots, and all.
If growing for seeds, allow the plants to flower. Cilantro flowers are highly attractive to beneficial insects like Syrphid flies, lacewings, and lady beetles.
