17 herbs that absolutely explode with growth when planted in march

March is a month of transformation in the garden, as the cold grip of winter begins to loosen and the promise of spring is just around the corner. For gardeners, this is a perfect time to start planting a variety of herbs that not only thrive in cool temperatures but also reward you with explosive growth. Planting herbs in March can set the stage for a bountiful harvest come summer, as many herbs prefer to establish their roots in cooler soil before the heat of summer arrives.
Whether you’re a seasoned gardener or a novice looking to add more flavor to your cooking, March offers an ideal window to plant a wide range of herbs that are not only easy to grow but also enhance your garden’s biodiversity. From culinary staples like basil and parsley to more unique varieties like lovage and sorrel, these 17 herbs are known for their vigorous growth when planted at the start of spring.
1. Basil: Fast-Growing Flavor Powerhouse for Early Spring
Basil is a beloved herb that thrives when planted in March, particularly in regions with milder climates. As the soil begins to warm, basil seeds germinate quickly, typically within 5 to 10 days. When sowing basil, space the seeds about 12 inches apart to allow ample room for each plant to grow. By mid-spring, you’ll have lush green leaves ready to harvest, adding a fresh burst of flavor to your culinary creations.
To optimize basil growth, ensure the plants receive plenty of sunlight, ideally 6-8 hours per day. Regularly pinch back the tops of the plants to encourage bushier growth and prevent early flowering, which can reduce leaf production. With the right conditions, basil can reach up to 24 inches in height, providing a plentiful supply for pesto, salads, and more.
2. Parsley: Hardy Vitamin-Rich Green That Loves Cool Weather
Parsley is an herb that can handle the cooler temperatures of March, making it a perfect candidate for early spring planting. Whether you choose the curly or flat-leaf variety, parsley seeds can be sown directly into the soil, spaced about 6 to 8 inches apart. The seeds may take up to three weeks to germinate, but the wait is worth it as parsley is rich in vitamins A, C, and K.
As a biennial, parsley can be harvested throughout its first year. In cooler climates, consider planting under a cold frame or cloche to protect young plants from unexpected frosts. As the plants mature, they will form dense clumps of vibrant green leaves, ideal for garnishing dishes or blending into sauces.
3. Cilantro: Cool-Season Herb That Bolts Into Growth in March
Cilantro is a cool-season herb that thrives in the cooler temperatures of March, making it an excellent choice for early spring planting. The seeds, also known as coriander, should be planted about 1/4 inch deep and spaced 6 inches apart in well-draining soil. Cilantro germinates quickly, often within 7 to 10 days, and benefits from full sun to partial shade.
Cilantro has a fast growth cycle and can be harvested as soon as the leaves reach a desirable size. To prolong the harvest, sow seeds every few weeks throughout the spring. Be mindful that cilantro tends to bolt, or go to seed, as the weather warms, so early planting in March can help maximize leaf production before the summer heat sets in.
