March is a great time to get your garden started, as it allows you to take advantage of the longer days and gradually warming soil. This period is perfect for planting vegetables that mature quickly and can tolerate light frosts.
In many regions, March is still quite chilly, especially in the mornings and evenings. However, as the month progresses, the days become longer and warmer, providing the perfect conditions for many vegetables to grow. It’s essential to choose varieties that are resistant to frost and can handle the unpredictable weather that often comes with early spring.
Preparing Your Garden
Before you start planting, it’s important to prepare your garden. Here are a few steps to ensure your soil is ready:
Check the Soil Temperature: Most vegetables prefer soil temperatures above 40°F (4°C). Use a soil thermometer to check the temperature, especially for vegetables like peas and carrots that can be planted as soon as the soil can be worked.
Remove Debris: Clear your garden of any debris or leftover plant material from the previous season. This helps prevent pests and diseases from taking hold.
Add Organic Matter: Mix in some compost or well-rotted manure to improve soil structure and fertility. This will help your vegetables grow strong and healthy.
Plan Your Layout: Decide which vegetables you want to plant and where. Consider companion planting to maximize space and reduce pests.
What Vegetables Are Good To Plant In March?
March is a versatile month for planting a wide range of vegetables. Here are some of the best options:
1. Broccoli
Broccoli is a cool-season crop that thrives in the cooler temperatures of early spring. It prefers well-drained, fertile soil and full sun. Plant broccoli seedlings about 18 to 24 inches apart to give them room to grow. Broccoli is a great choice for March because it matures relatively quickly and can tolerate light frosts.
2. Cauliflower
Similar to broccoli, cauliflower is another cool-season crop that does well in March. It requires similar conditions to broccoli and should be planted about the same time. Cauliflower is a bit more sensitive to frost, so make sure to cover it if a late frost is predicted.
3. Kale
Kale is a hardy, cool-season green that can be planted as soon as the soil can be worked. It prefers well-drained soil and partial shade. Kale is very resistant to frost and can continue to produce leaves throughout the spring.
4. Spinach
Spinach is one of the earliest vegetables you can plant in the spring. It prefers cooler temperatures and can tolerate light frosts. Plant spinach seeds about 2 to 3 inches apart in well-drained soil. Spinach grows quickly and can be harvested in as little as three weeks.
5. Lettuce and Other Leafy Greens
Lettuce, arugula, and other leafy greens are perfect for early spring. They prefer cooler temperatures and can be planted as soon as the soil is workable. These greens are quick to mature and can be successionally planted every week or two to ensure a continuous harvest.
6. Peas
Garden peas are one of the first vegetables to be planted in the spring. They can be planted as soon as the soil can be worked, usually when it reaches about 40°F (4°C). Peas prefer well-drained soil and a trellis or other support to climb on. They are very resistant to frost and can thrive in the cooler temperatures of early spring.
7. Carrots
Carrots can be planted in early spring as soon as the soil is workable. They prefer well-drained, loose soil to prevent forking. Sow carrot seeds thinly and evenly, about ¼ inch deep. Carrots are slow to germinate, so be patient and keep the soil consistently moist.
8. Radishes
Radishes are quick-growing and can be planted in as little as three weeks. They prefer well-drained soil and full sun. Radishes can be planted alongside other vegetables like carrots and beets to help deter pests.
9. Beets
Beets are another cool-season crop that does well in March. They prefer well-drained soil and full sun. Plant beet seeds about 1 inch deep and 1 to 2 inches apart. Beets are relatively frost-tolerant and can be harvested in about 60 days.
10. Onions
Onions can be planted in early spring, either from sets or seeds. They prefer well-drained soil and full sun. Onions are hardy and can tolerate light frosts, making them a great choice for March.
11. Potatoes
In many regions, March is a good time to plant potatoes. They prefer well-drained, loose soil and full sun. Plant seed potatoes about 2 to 4 inches deep, with the “eyes” facing upwards. Potatoes are relatively frost-tolerant and can be harvested in about 70 to 100 days.
12. Cabbage
Cabbage is a cool-season crop that thrives in the cooler temperatures of early spring. It prefers well-drained, fertile soil and full sun. Plant cabbage seedlings about 18 to 24 inches apart to give them room to grow. Cabbage is a bit more sensitive to frost, so ensure it’s covered if a late frost is predicted.
13. Brussels Sprouts
Brussels sprouts are similar to cabbage and broccoli, preferring cooler temperatures and well-drained soil. They take longer to mature, so they should be planted early in the month. Brussels sprouts are relatively frost-tolerant but may need protection during severe frosts.
Tips for Successful Planting
To ensure a successful harvest, here are a few tips to keep in mind:
Check the Weather: Always check the weather forecast before planting. Avoid planting during periods of extreme cold or wet weather.
Use Row Covers: If you live in an area prone to late frosts, use row covers to protect your plants. These lightweight covers can be placed over your vegetables to keep them warm and safe.
Water Consistently: Keep the soil consistently moist, especially for seeds that are germinating. However, avoid overwatering, which can lead to rot and other problems.
Mulch Around Plants: Mulching helps retain moisture, suppress weeds, and regulate soil temperature. Use organic mulch like straw or wood chips around your plants.
Monitor for Pests: Keep an eye out for pests like slugs, snails, and aphids. Use natural pest control methods whenever possible to maintain a healthy ecosystem in your garden.
Conclusion
March is a fantastic time to get your garden started, offering a wide range of vegetables that can thrive in the cooler temperatures of early spring. By choosing the right vegetables and following a few simple gardening tips, you can set yourself up for a successful and bountiful harvest. Whether you’re planting broccoli, spinach, or peas, the key is to prepare your soil well and provide your plants with the right conditions to grow. Happy gardening!
