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.

Growing Tips

Harvest outer leaves first, leaving the center to keep growing. Can survive temperatures down to 10°F with mulch protection.

Companion Planting

Plant kale alongside these companions for better growth:

Beets Celery Herbs Onions

Keep kale away from:

Strawberries Tomatoes

The Bottom Line

Kale can be grown successfully across Maryland, but your exact planting dates depend on which region you're in. Western Maryland gardeners should plan around a May 1 - May 15 last frost, while those in Eastern Shore can typically plant earlier.
