March Planting Guide: What to Sow & Grow Now

As the days lengthen and the weather begins to warm in March, gardeners often turn their attention to preparing for the upcoming growing season. This month presents a prime opportunity to initiate a variety of crops, both indoors and directly in the garden, depending on local climate conditions and the specific plants being cultivated.

For those with access to a greenhouse or a sunny windowsill, March is an ideal time to start seeds indoors. Tomatoes, a popular garden staple, benefit from an early start, allowing them to develop strong root systems before being transplanted outdoors after the last frost. Different varieties, from cherry tomatoes to larger beefsteak types, can be selected based on personal preference and available space. Similarly, peppers, including both sweet bell peppers and various chili varieties, thrive when germinated indoors in controlled conditions. They require consistent warmth and light to ensure successful sprouting and initial growth. Eggplants also fall into this category, appreciating an early start to maximize their growing period.

Beyond these common nightshades, several other vegetables can be initiated indoors in March. Leeks, known for their mild onion-like flavor, can be sown in trays and later transplanted. Onions, particularly those grown from seed rather than sets, also benefit from an early indoor start. Various herbs, such as basil, oregano, and thyme, can be started from seed indoors, providing a continuous supply throughout the season. These herbs often germinate well in warm conditions and can be easily moved outdoors once the weather stabilizes.

As for direct outdoor sowing, March offers opportunities for a range of cool-season crops, especially in regions where the soil has begun to thaw and is workable. Peas, both shelling and snap varieties, can be planted directly into the ground. They prefer cooler temperatures and can tolerate light frosts, making them suitable for early spring planting. Broad beans, another legume, also thrive in similar conditions and can be sown directly.

Root vegetables are another excellent choice for direct sowing in March. Carrots, with their diverse range of colors and shapes, can be planted directly into well-prepared soil. Radishes, known for their quick growth, are perfect for successive sowings, providing a continuous harvest. Beets, both for their roots and their greens, can also be sown directly. Parsnips, which require a longer growing season, can be planted early in March to allow ample time for development.

Leafy greens are also well-suited for early spring planting. Spinach, lettuce (various types), and Swiss chard can be sown directly into the garden. These crops generally prefer cooler temperatures and can bolt (go to seed) in hot weather, making early spring an optimal time for their cultivation. Kale, a highly nutritious leafy green, is also resilient to cooler temperatures and can be planted directly.

Beyond vegetables, March is a good time to consider planting certain flowers, especially those that can be started from seed. Sweet peas, known for their fragrant blooms, can be sown directly into the ground in early spring. Other hardy annuals and perennials can also be started from seed indoors or directly sown, depending on their specific requirements.

Finally, while not directly planting, March is a crucial month for garden preparation. This includes amending the soil with compost and other organic matter, planning garden layouts, and ensuring all necessary tools are in good working order. It's also a time to observe the garden, noting any areas that might need improvement or protection as the season progresses. The activities undertaken in March lay the groundwork for a productive and bountiful growing season.
