Growing Cilantro in Maryland
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
Moderate climate with four seasons. Hot, humid summers. Good growing season. Diverse growing conditions across the state.
Growing season length varies across Maryland: Western Maryland (5b, 6a) has a last frost around May 1 - May 15, while Eastern Shore (7a, 7b, 8a) sees frost end around Apr 1 - Apr 15. This difference matters for cilantro — adjust your planting dates to match your specific region.
