Carrot

Carrots are a cool-weather crop that can be started in March. You can plant carrots in summer because they can tolerate the cooler temperatures and occasional frosts that are common during this time. They prefer loose, well-draining soil and full sun. They have a relatively short growing season, which means you can harvest carrots in just a few weeks and enjoy fresh, crunchy carrots by late spring or early summer. Finally, they are low-maintenance and perfect for gardeners of all levels.

Cucumber

Cucumbers are a refreshing addition to any garden. It’s smart to start cucumber seeds indoors in cooler climates, as you can transplant them outdoors once the weather warms up. Since cucumbers like climbing, you’re recommended to use trellis to establish vertical gardening. Cucumbers have a relatively short growing cycle of 50 to 70 days so this early start ensures a bountiful cucumber harvest by mid-summer. Additionally, you can take advantage of the warming soil and increasing daylight in March. March ensures the optimal conditions cucumbers need to thrive.

Basil

Basil is a versatile and aromatic herb that can be used in a wide variety of dishes, from classic Italian recipes like pesto and caprese salad to more exotic cuisines. You can grow basil in March, especially in regions where the weather is starting to warm up. It thrives in the mild temperatures and increased daylight hours that March typically offers. This is good for them to germinate and achieve early growth. Additionally, it’s relatively easy to grow and maintain basils. For these reasons, it’s ideal to start sowing basil seeds to plant in March.

Peas

Peas are among the first crops to be planted as the ground thaws. They are an excellent vegetable to plant in March due to their hardiness and preference for cooler temperatures. They thrive in the mild weather of early spring, making March an ideal time to start them outdoors. Peas are relatively easy to grow and can tolerate frost, which means they can be planted directly into the garden without the need for indoor starts. Also, they have a relatively short growing season, so you can achieve a harvest by late spring or early summer. Starting to grow peas in March ensures a bountiful and healthy harvest, while also adding beauty and productivity to your garden.

Lettuce

Lettuce is a fast-growing vegetable that loves cool weather. The cooler weather helps prevent lettuce bolting, which is when the plant goes to seed prematurely, making the leaves bitter. Planting lettuce in March allows them to grow steadily without the stress of extreme heat. Additionally, lettuce has a relatively short growing season, often maturing in just a few weeks, so starting early ensures a bountiful harvest by late spring or early summer. More importantly, March provides the right balance of sunlight and moisture, which are essential for healthy growth. You can grow them in small spaces, even on a windowsill, and offer quick results.

Chard

It’s a cool-season crop that thrives in mild temperatures, typically between 50-75°F (10-24°C). Planting chard in March allows it to establish strong roots and foliage before the heat of summer, which can cause the plant to bolt (prematurely flower) and become bitter. March planting takes advantage of the cool, moist soil conditions that chard prefers for germination and early growth. Additionally, chard is relatively frost-tolerant, making it well-suited for early spring planting in many regions. By starting in March, you can enjoy a prolonged harvest period, as chard continues to produce tender leaves throughout the spring and into early summer. With proper care, you can even harvest them in the fall.

Pumpkin

It’s suitable for you to grow pumpkins in March because they require a long growing season - typically 75 to 100 days to reach maturity. By starting seeds indoors in March, you can give your pumpkins a head start, especially in regions with shorter growing seasons. This early start ensures that the plants have enough time to develop and produce a bountiful harvest before the first fall frost. Additionally, March provides a good balance of cooler temperatures and increasing daylight, which are conducive to germination and early growth. However, it’s important to note that pumpkins should be started indoors in March to protect them from frost. Once the seedlings are strong and the weather warms up, they can be transplanted outdoors for continued growth.

Pansies & Violas

Pansies and violas are hardy and adaptable to early spring conditions. These plants can tolerate cooler temperatures and even light frosts, so they are ideal for the fluctuating weather in March. They thrive in the cool, moist soil conditions prevalent during this time and can provide early spring color, brightening up gardens and borders. Additionally, they are relatively low maintenance, requiring only regular watering and occasional feeding. Their resilience and ability to bloom early make them a reliable choice for adding vibrant hues to the garden in March.

Cornflowers

Cornflower is another March plant worth your attention. They are hardy annuals that can tolerate the cooler temperatures and variable weather conditions in early spring. Sowing seeds to plant in March enables them to become established before summer bloom. Additionally, cornflowers thrive in full sun and well-drained soil, which are conditions that can often be found in March as the soil begins to warm and dry out. Like many other March plants, they require minimal care. Lastly, planting in March ensures a vibrant display of blooms from early summer through to the first frost, adding a splash of color to the garden.

Marigolds

You can grow marigolds indoors in March. Marigolds are warm-weather plants that thrive in temperatures above 40°F (≈ 4.44°C) and are not frost-tolerant. To get a head start on the growing season, especially in regions with late last frost dates, it’s recommended to start marigold seeds indoors 6–8 weeks before the last expected frost. This timing typically places seed sowing in March, allowing the seedlings to be ready for transplanting outdoors once the soil warms and the danger of frost has passed. By starting indoors, you ensure that your marigolds will be well-established and ready to bloom early in the summer.

Then these plants are ready for transplanting outdoors once the threat of frost has passed. This early start ensures that the petunias have enough time to grow and bloom profusely during the warmer months. Additionally, starting petunias indoors gives you a wider variety of choices and can be more cost-effective.

By sowing seeds in March, especially in regions with mild climates or after the last frost, the soil begins to warm up. This is likely to provide a suitable environment for germination. Besides, the early season also allows the plants to establish strong roots and develop robust foliage before the heat of summer. Additionally, your plants can take advantage of increasing daylight hours when growing in March.
