What to Plant in March: The Best Early Spring Crops - Modern Farmer

"It's a good time to sow seeds of cool-weather annuals and warm-weather annuals that require a long period before they can be transplanted. In areas where winter is still in full force, sowing indoors is a good option. Under cover, growers in multiple areas can sow directly. As long as the season's remaining freezes aren't deep and long, plenty of crops can be sown."

"Spinach is a great early spring plant to sow directly in beds. As cover, it stabilizes soil, preventing weeds and erosion, while building soil biomass. As a market item, it's nutritious and desirable. Succession sow every two weeks until it's too hot for cold-loving greens."

"Add carrots to your 'What to Plant In March' list. Sow these directly in the garden a couple of weeks before your last frost, or in a covered bed. If you've never sold carrots in your market stand, it's worth the effort, as mass-produced carrots just can't stand up to the flavor."

March presents an optimal planting window across North America for both cool-weather and warm-weather crops. Direct sowing works well in areas where remaining freezes are mild, as many plants tolerate light frost and recover when temperatures warm. Indoor sowing suits regions still experiencing harsh winter conditions. Cool-weather crops like spinach and carrots thrive when planted in March, either directly in beds or under cover. Spinach serves dual purposes as a cover crop for soil stabilization or as a market crop, with succession planting every two weeks until heat arrives. Carrots should be sown a couple weeks before the last frost date. Starting summer crops indoors during March allows transplants to be ready before intense summer heat, maximizing growing season efficiency.
