8 Reasons To Use Cover Crops In Your Garden – Plants That Build Soil

Cover crops are an essential and often underappreciated element of sustainable gardening and agriculture. They offer numerous benefits that not only enhance your garden’s soil but also improve its overall health and productivity. Here are eight compelling reasons to use cover crops in your garden:

  1. Soil Enrichment: Cover crops are known for their ability to fix nitrogen from the atmosphere into the soil. Legume cover crops, like clover and peas, help increase soil fertility by adding nitrogen, a vital nutrient for plant growth.
  2. Weed Suppression: Cover crops create a dense ground cover, which shades out weeds and competes with them for resources, reducing the need for chemical weed control and manual weeding.
  3. Erosion Control: The root systems of cover crops help bind the soil together, preventing erosion. This is especially beneficial on slopes and in areas prone to heavy rainfall.
  4. Moisture Retention: Cover crops can improve the soil’s water-holding capacity. They reduce water runoff, increase water infiltration, and help maintain soil moisture levels, which is especially valuable in dry regions.
  5. Improved Soil Structure: Cover crop roots penetrate deep into the soil, breaking up compacted soil and promoting better aeration and drainage. This enhanced soil structure supports healthier root development for your main crops.
  6. Pest and Disease Management: Certain cover crops can disrupt the life cycles of soil-borne pests and diseases, reducing the likelihood of infestations in subsequent crops.
  7. Biodiversity and Beneficial Insects: Flowering cover crops attract beneficial insects like bees and ladybugs, which help with pollination and natural pest control.
  8. Crop Rotation: Cover crops can be strategically chosen to complement your main crops, aiding in crop rotation and reducing the risk of soil-borne diseases associated with monoculture.

Cover crops (Green manure plants) are an amazing thing to use to improve and build the soil in your garden. Today I’ll be showing you the successful cover crops I’ve grown in my food forest garden and talk about some of the amazing benefits of using cover crops in your garden. These plants not only help to build soil and improve soil health, but they suppress weeds, prevent erosion, improve the soil biology, add nutrients, retain moisture in soil and heaps more!

I’ve had a lot of fun growing these nitrogen fixing plants as well as some other types of green manure plants, like peas, mustard, daikon radish, lupin, etc. Whether you want to use these in your vege garden, or anywhere else on your land, this video will give you an idea of how to use cover crops in your garden and what is green manure.
