Growing Kale in Maryland
Kale in Maryland's Climate
Kale grows from early spring through late fall in your climate — frost-tolerant enough to be one of the first and last crops of the season. Fall-harvested kale sweetened by frost is the highlight. Summer kale production may pause during the hottest weeks (above 85°F) but typically resumes as temperatures moderate.
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. Kale can handle frost well, which is an advantage in Maryland's climate. You can push planting dates earlier in spring and extend into fall.
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 kale — adjust your planting dates to match your specific region.
