What is a companion plant?

Companion planting is the practice of growing different plants together for mutual benefit. Companion plants can help to repel pests, attract beneficial insects, improve soil health, and increase crop yields. There are many different combinations of companion plants that can be used, depending on the needs of your garden or farm.

Crimson clover as a companion plant

Crimson clover is an excellent choice as a companion plant, particularly for vegetable crops. It has a deep taproot that can help to break up compacted soil, and it adds nitrogen to the soil through a process called nitrogen fixation.

Nitrogen is an essential nutrient for plant growth, and many vegetable crops require large amounts of it. By planting crimson clover as a companion, you can help to provide the nitrogen that your vegetables need.

Crimson clover also attracts pollinators, such as bees and butterflies, which can help to improve the yield of your crops. In addition, it can help to suppress weeds by shading the soil and competing with them for nutrients.

Benefits of Crimson Clover as a Companion Plant

  1. Soil Enrichment: Crimson clover is a nitrogen-fixing plant, which means it can take nitrogen from the air and convert it into a form that plants can use. When grown as a companion plant, crimson clover can help to enrich the soil by providing an additional source of nitrogen for the other plants in the garden.
  2. Weed Suppression: The dense growth habit of crimson clover can also help to suppress weeds in the garden. The thick foliage shades out weed seeds, preventing them from germinating, while the roots of the crimson clover help to improve soil structure, making it more difficult for weeds to take hold.
  3. Pest Control: Crimson clover attracts beneficial insects such as ladybugs, lacewings, and hoverflies, which prey on garden pests like aphids and mites. Additionally, the thick foliage of the clover can provide shelter for these insects, helping to create a more balanced and healthy ecosystem in the garden.
  4. Erosion Control: The roots of crimson clover help to hold soil in place, reducing erosion and preventing soil from washing away during heavy rain events.

How to grow crimson clover as a companion plant

Crimson clover is relatively easy to grow, and it can be sown in either the spring or fall. It prefers well-drained soil and full sun to partial shade. To plant crimson clover, follow these steps:

  1. Prepare the soil: Before planting, remove any weeds or debris from the planting area. Loosen the soil to a depth of about 6 inches with a garden fork or tiller.
  2. Sow the seeds: Scatter the seeds evenly over the soil surface. The recommended seeding rate is about 20-25 pounds per acre, or 0.5-1.0 pounds per 1,000 square feet. If you are planting in rows, space them about 18-24 inches apart.
  3. Cover the seeds: Lightly rake the soil over the seeds to cover them with a depth of about 1/4 to 1/2 inch. Water the area thoroughly after planting.
  4. Maintain the plants: Crimson clover requires little maintenance once it is established. Water the plants regularly if rainfall is scarce, and remove any weeds that may compete with the clover. In the fall, you can mow the plants down to about 3-4 inches in height to help with decomposition.

Using crimson clover as a cover crop

Crimson clover is also an excellent choice as a cover crop. A cover crop is a crop that is grown primarily for the purpose of improving soil health, rather than for harvest.

Cover crops can help to prevent soil erosion, improve soil fertility, and suppress weeds. Crimson clover is particularly useful as a cover crop because it adds nitrogen to the soil through nitrogen fixation.

To use crimson clover as a cover crop, follow the same planting steps as described above. In the fall, you can either till the plants into the soil or let them die off naturally over the winter. If you choose to till the plants, wait until they have reached full maturity and have begun to flower. Tilling before this point can cause the nitrogen to be lost from the soil.
