Cilantro in Maryland's Climate

Cilantro thrives in your cool springs and falls but bolts rapidly once temperatures exceed 80°F. Succession plant every 2-3 weeks during the cool windows. Let some plants bolt to produce coriander seeds (a spice in their own right) and self-seed for volunteer plants next season.

Soil Considerations for Maryland

Clay soils in Piedmont. Sandy loam on Eastern Shore. Acidic in most areas. Rich alluvial soils along river valleys.

Maryland Climate & Growing Season
