Have you ever considered using cover crops in your home garden, or did you think they were just for organic farmers? While the use of these plants is much more common in agriculture than the home garden these plants can be a valuable tool for the home gardener. And they’re a whole lot easier to use than you’d think!

These unsung heroes play a crucial role in maintaining soil health, preventing erosion, and improving overall crop productivity during the colder months. Today, we’ll explain what cover crops are, why you should use them during fall gardening, and what the best ones are for your home garden. 

What Are Cover Crops?

Also known as “green manure,” this is a diverse group of plants grown primarily to benefit the soil and ecosystem rather than for harvesting. These crops are sown during specific periods of the year, such as fall and winter, to provide ground cover, and protect and enrich the soil between plantings.

Understanding Cover Crops

The key role of cover crops is to enhance soil health and fertility. They prevent soil loss, especially during heavy rain or snowmelt. Beyond improving the soil, these helpful plants can also attract beneficial insects, birds, and other wildlife, promoting biodiversity in agricultural ecosystems.

Many cover crops grow quickly and densely, outcompeting weeds for sunlight, water, and nutrients. This natural weed control reduces the need for herbicides. Certain types have deep root systems that can access nutrients deeper in the soil. Those nutrients are then brought to the surface when the cover crop is later incorporated into the soil. For a better understanding these unique benefits I highly recommend you check out this article, but we’ll go over some basics below.

Benefits of Cover Crops in Fall and Winter

Cover crops play an especially important role in fall and winter gardening. You may use raised bed frost covers to protect plants from the cold. Well, your soil needs protection in the winter cold, too! Cover crops help to shield it from the erosive forces of winter rains and snowmelt. This prevents soil erosion and maintains your soil’s structure, reducing the risk of nutrient runoff and loss.

These cover crops continue to grow and absorb nutrients from the soil during the fall and winter, effectively trapping and storing valuable nutrients that might otherwise be lost. When the plants are later incorporated into the soil, these nutrients are released, enriching it for the next growing season.

Choosing the Right Cover Crops

It’s important to consider your garden’s unique needs when deciding on a cover crop to use. Different plants bring different advantages. They have different appearances, water and light requirements, and growth cycles. If you’re not sure where to start, here are some of our favorites. 


Legumes, such as clover, vetch, and winter peas, are an excellent choice for fall and winter planting. Plants in this category have a remarkable ability to capture atmospheric nitrogen and convert it into a form that can be used by plants. This natural nitrogen-fixing process enriches the soil with this essential nutrient, benefiting subsequent crops.

Grasses, such as rye, wheat, barley, and oats, are hardy and resilient cover crop choices for fall and winter. These and other drought-tolerant perennials have extensive root systems. Those roots help bind soil and prevent erosion, making them ideal for areas prone to heavy rainfall or runoff. They are also valuable for weed suppression, competing effectively with weeds and reducing weed pressure. If you’re not a fan of grasses, there are plenty of alternatives to grass that are similarly effective.

Brassicas and Mustards:

Plants such as radishes, turnips, rapeseed, and mustards, are fast-growing and versatile options for your garden. Brassicas release compounds that can suppress soil-borne pests and diseases. That makes these plants valuable for disease management and pest control. Some brassicas also have deep roots that break up soil compaction and improve aeration and drainage.

Planting and Managing Cover Crops

Once you’ve chosen the right cover crops for your fall and winter season, it’s time to learn how to plant and manage them. Timing is critical when planting – aim to plant them in fall, after you do your fall garden cleanup is often a great time to go ahead and get the seeds in the ground, or before you start planting spring bulbs

Prepare the soil by removing debris and weeds and ensuring a smooth, level seedbed. Lightly till or rake the surface to create a good seed-to-soil contact. Different crops require different seeding rates to achieve the desired coverage. Typically, you can just sprinkle your seeds over your soil and rake them in. 

To manage your cover crops, remove any weeds that pop up during the early growth stages. Keep your it well-watered, and cut your chosen variety (usually before you’re ready to plant your spring vegetables) before it flowers or goes to seed. Once it’s cut, work the plant material and roots into the soil to allow it to release nutrients and nourish the soil for whatever you choose to plant next. 


Fall and winter cover crops can be a valuable addition to any garden. Although they don’t provide anything you can harvest, they can add vital nutrients to your soil, improve soil structure, help suppress weeds, and act as a natural disease and pest repellent. 

Choosing the right variety can take some time – you might like to experiment with different fall and winter cover crops to find what works best for your garden. If you have some space after your fall vegetable harvest and aren’t sure what to plant next, consider rejuvenating your garden beds with fall and winter cover crops!
