20 Nitrogen-Loving Plants for Your Garden


When it comes to gardening, one of the most important factors to consider is the nutrient content of the soil. Nitrogen is one of the essential nutrients that plants need to thrive and grow. It is responsible for promoting healthy leaf and stem growth, as well as increasing overall plant productivity.

If you are looking to improve the nitrogen content in your garden soil, there are many plants that can help. These nitrogen-loving plants have the ability to take nitrogen from the air and convert it into a usable form for other plants. In this article, we will explore 20 such plants that you can incorporate into your garden to boost its nitrogen levels and improve overall plant health.

1. Legumes

Legumes, such as beans, peas, and lentils, are well-known nitrogen fixers. They have specialized nodules on their roots that host bacteria capable of converting atmospheric nitrogen into a form that plants can use. What makes legumes even more interesting is that they not only fix nitrogen for their own use but also release excess nitrogen into the soil, benefiting neighboring plants.

2. Alfalfa

Alfalfa is another excellent nitrogen-fixing plant that is commonly used as a cover crop or green manure. Its deep root system helps improve soil structure and increase the nitrogen content. You can sow alfalfa seeds in your garden and cut down the plants once they reach a certain height. Leave the cuttings on the ground to decompose and release nitrogen into the soil.

3. Clover

Clover is often used as a ground cover crop in gardens because of its nitrogen-fixing abilities. It works particularly well in vegetable gardens where it not only adds nitrogen to the soil but also suppresses weed growth. Grow clover between rows of vegetables or as an underplanting to boost nitrogen levels naturally.

4. Sunflowers

Sunflowers are not only beautiful to look at, but they also have the ability to accumulate large amounts of nitrogen in their tissues. When the sunflowers die back, they release this nitrogen into the soil, benefiting nearby plants. Consider planting sunflowers as a border or mixed within your garden to reap these nitrogen benefits.

5. Lupines

Lupines are vibrant flowering plants that are excellent at fixing nitrogen in the soil. Their deep roots help break up compacted soil and improve overall soil health. Lupines are also great for attracting pollinators to your garden, making them a win-win addition to any garden space.

6. Fava Beans

Fava beans, also known as broad beans, are not only a delicious addition to your meals but also a nitrogen booster for your garden. They have a symbiotic relationship with specific bacteria that fix nitrogen in the soil. Plant fava beans as a cover crop during the winter months to improve soil fertility.

7. Red Clover

Red clover is a popular nitrogen-fixing plant that is often used as a cover crop or green manure. It grows quickly and can be cut down several times throughout the growing season to release nitrogen into the soil. Red clover also attracts beneficial insects to your garden and helps suppress weed growth.

8. Peanuts

Peanuts are not only a tasty snack but also a nitrogen-fixing crop. They have a unique characteristic of producing small, nodulated structures on their roots that house nitrogen-fixing bacteria. Plant peanuts in your garden to improve nitrogen levels and enjoy a fresh supply of peanuts at the same time.

9. Vetch

Vetch is a fast-growing, nitrogen-fixing cover crop that can provide many benefits to your garden. It improves soil structure, suppresses weeds, and adds nitrogen to the soil. Some varieties of vetch even have beautiful flowers, making them a visually appealing addition to your garden space.

10. Cowpeas

Cowpeas, also known as black-eyed peas, are highly productive and nitrogen-fixing plants. They can be grown as both a cover crop and a food source. Cowpeas are known for their ability to tolerate hot weather and provide ample nitrogen to the soil, making them an excellent choice for warm climates.

11. Sweet Peas

Sweet peas not only add a delightful fragrance to your garden but also contribute to nitrogen fixation. These climbing plants are great for trellises and can improve soil health while adding beauty to your landscape. Plant sweet peas near other nitrogen-loving plants for maximum nitrogen benefits.

12. White Dutch Clover

White Dutch clover is a low-growing, nitrogen-fixing plant that is ideal for lawns and ground cover. It can withstand foot traffic and is often used as a natural alternative to traditional turf grass. White Dutch clover adds nitrogen to the soil, requires less maintenance than regular grass, and attracts pollinators to your garden.

13. Sweet Potatoes

Sweet potatoes are not only a delicious and nutritious crop but also a great nitrogen-loving plant. They have a tendency to produce an abundance of organic matter that decomposes and releases nitrogen into the soil. Plant sweet potatoes in your garden to enjoy their tasty tubers and improve soil fertility.

14. Mustard Greens

Mustard greens are fast-growing leafy vegetables that have the ability to scavenge nitrogen from the soil. They are often used as a cover crop or intercropped with other vegetables to boost nitrogen levels. Mustard greens also have the added benefit of being an edible green that can be harvested for tasty salads and stir-fries.

15. Garden Peas

Garden peas are not only a favorite vegetable for many, but they also have the ability to fix nitrogen in the soil. The pea plants form nodules on their roots that house nitrogen-fixing bacteria. Plant garden peas in your garden as a food source and enjoy the added benefit of improved nitrogen levels.

16. Soybeans

Soybeans are a versatile crop that is well-known for its nitrogen-fixing abilities. They are commonly used as a rotational crop to replenish soil nitrogen levels. Soybeans also have many other uses, such as animal feed, oil production, and as a source of plant-based protein.

17. Crimson Clover

Crimson clover is a cool-season annual that is often used as a cover crop or green manure. It has beautiful, vibrant red flowers that attract pollinators and adds nitrogen to the soil when cut down and left to decompose. Consider planting crimson clover in your garden during the fall or spring to enjoy its nitrogen-boosting benefits.

18. Winter Wheat

Winter wheat is a cereal grain that not only provides a harvestable crop but also improves nitrogen levels in the soil. It can be used as a cover crop during the winter months to prevent erosion and add organic matter to the soil. Winter wheat is a great option for regions with cold winters and mild summers.

19. Barley

Barley is another cereal grain that can be grown as a cover crop or food source. It has the ability to scavenge nitrogen from the soil and release it when the plant decomposes. Barley is also known for its ability to enhance soil structure and suppress weed growth, making it a beneficial addition to any garden.

20. Oats

Oats are a widely cultivated cereal grain that provides many benefits to the garden. They have the ability to scavenge nitrogen from the soil and improve soil structure. Oats can be grown as a cover crop or used as a food source, making them a versatile and nitrogen-loving plant to include in your garden.

My 2 Cents

Boosting nitrogen levels in your garden is essential for healthy plant growth and overall productivity. By incorporating nitrogen-fixing plants into your garden, you can naturally increase nitrogen content in the soil and reduce the need for synthetic fertilizers. Not only will this benefit your plants, but it will also promote a more sustainable and environmentally friendly gardening practice. So, why not give these nitrogen-loving plants a try and watch your garden flourish?
