15 vegetables you can plant directly outside in early march

As the first signs of spring emerge, gardeners everywhere eagerly anticipate the start of the planting season. Early March marks a critical time for sowing seeds directly into the ground, especially for those vegetables that thrive in cooler temperatures. Planting in early March takes advantage of the cool, moist soil conditions, allowing certain crops to establish themselves before the hotter months.

While it's important to pay attention to local climate and weather forecasts, many vegetables are well-suited for direct sowing in early spring. These hardy varieties can handle light frosts and are quick to germinate, ensuring a head start on the growing season. Here, we'll look at 15 vegetables you can plant directly outside in early March, bringing fresh produce to your table in just a few short weeks.

Peas are one of the quintessential cool-season crops, thriving when planted directly in the ground as soon as the soil can be worked. They germinate well in soil temperatures as low as 40°F (4°C) and can tolerate light frost, making them ideal for early March planting. Plant peas 1 inch deep and 2 inches apart in well-draining soil. With proper support, such as a trellis, peas can climb up to 6 feet tall, maximizing garden space and yielding sweet pods in about 60 to 70 days.

Spinach is another cool-loving vegetable that can be sown directly into the garden in early March. This leafy green thrives in temperatures between 45°F and 75°F (7°C to 24°C) and is quick to germinate, often sprouting within 7 to 14 days. For a continuous harvest, plant seeds 1/2 inch deep and 2 inches apart, thinning to about 4 inches once seedlings are established. Spinach leaves can be harvested as baby greens or left to mature, providing a versatile addition to early spring salads.

Radishes are a favorite for early spring planting due to their fast growth and tolerance of cool conditions. These root vegetables can be harvested in as little as 3 to 4 weeks after planting. Sow radish seeds 1/2 inch deep and 1 inch apart in rows spaced 12 inches apart. As a quick-maturing crop, radishes can be sown every two weeks to ensure a continuous supply of crisp, spicy roots.

Carrots are well-suited for early March planting, as they germinate best in cool soil. Plant carrot seeds 1/4 inch deep and 2 inches apart, allowing rows to be spaced 12 inches apart. Carrots require consistent moisture to germinate, which can take 14 to 21 days, so patience is key. Once established, carrots will grow steadily, producing sweet roots ready for harvest in about 70 to 80 days.

Lettuce is a hardy green that thrives in the cooler temperatures of early spring. Sow seeds directly into the garden, 1/4 inch deep and 1 inch apart, thinning to 6 to 12 inches for full-size heads or leaving closer for leaf varieties. Lettuce grows quickly, with baby leaves ready to harvest in just 30 days. For a continuous supply, sow seeds every two weeks throughout the spring.

Kale is a member of the brassica family known for its cold tolerance and nutritional value. It can be planted directly outside in early March and will thrive in temperatures as low as 20°F (-6°C). Sow seeds 1/2 inch deep and 1 inch apart, thinning seedlings to 12 inches apart once established. Kale leaves can be harvested as needed, making it a versatile and long-lasting addition to the spring garden.

Beets are a dual-purpose crop, providing both edible roots and tender greens. Plant beet seeds 1/2 inch deep and 3 inches apart in rows spaced 12 inches apart. Beets prefer cool soil and will germinate in temperatures as low as 50°F (10°C). Harvest young greens for salads and allow roots to mature for about 50 to 70 days before harvesting.

Swiss chard is a colorful, hardy green that can be sown directly into the garden in early March. Its tolerance to cold and vibrant stems make it a popular choice for early planting. Sow seeds 1/2 inch deep and 4 inches apart, thinning to 12 inches once seedlings are large enough. Swiss chard can be harvested continuously, providing a steady supply of nutritious leaves throughout the season.

Onions can be planted from seeds or sets directly into the garden in early March. Plant sets 1 inch deep and 4 inches apart in rows spaced 12 inches apart. Onions need full sun and well-draining soil to thrive. While seeds take longer to mature, planting sets allows for earlier harvests. Onions will be ready to harvest in about 100 to 175 days, depending on the variety.

Broad beans, also known as fava beans, are hardy legumes that thrive in cool weather. They can be sown directly outdoors in early March, as soon as the soil is workable. Plant seeds 2 inches deep and 6 inches apart, with rows spaced 18 inches apart. Broad beans can tolerate temperatures as low as 40°F (4°C) and are typically ready for harvest in 80 to 100 days.

Arugula is a fast-growing leafy green that loves cooler temperatures. It can be sown directly into the garden in early March for a peppery addition to salads.

Pak choi and other Asian greens are ideal for early March planting due to their fast growth and cold tolerance. Sow seeds 1/2 inch deep and 1 inch apart, thinning to 6 inches once seedlings are established. These greens thrive in temperatures as low as 50°F (10°C) and can be harvested in just 30 to 45 days. They are perfect for stir-fries, salads, and soups.

Parsnips are a slow-germinating root crop that benefits from early March planting. Sow seeds 1/2 inch deep and 3 inches apart in rows spaced 12 inches apart.
