Crimson clover can be planted as a winter annual in warm climates. It can also be planted in the fall in cool climates.

10. Can Be Used for Short-Term Periods

Crimson clover is a common sight in pastures and meadows, often used as a cover crop or forage for livestock.

But what many people don’t know is that crimson clover can also be used for short-term periods, in order to improve the quality of the soil.

The roots of crimson clover are deep and dense, making it an excellent choice for preventing soil erosion.

11. Improves Fertility for Corn and Cotton

A recent study found that crimson clover inhibits the growth of a fungus that competes with corn and cotton plants for nitrogen.

This means that by planting crimson clover, farmers can reduce the amount of nitrogen fertilizer they need to use, saving money and reducing environmental impact.

Crimson clover also has the added benefit of providing habitat for beneficial insects such as bees and ladybugs.

12. A Great Staple Forage

Crimson clover is a great staple forage. It is easily digestible and has a high protein content which makes it ideal for livestock.

Crimson clover is also high in calcium and phosphorus which are essential for the growth and development of bones and teeth.

Furthermore, crimson clover is known to improve the quality of milk produced by dairy cows.

It produces a high-quality forage that is high in crude protein and digestible energy. It also has a high tannin content, which makes it unpalatable to some animals.

However, crimson clover can be an excellent forage crop for sheep, goats, and cattle.

When grazed, crimson clover can help to improve the quality of the soil by increasing nitrogen levels. When used for hay, crimson clover can provide a nutritious and palatable feed for livestock.

13. Suppresses Weeds

Crimson clover is a beautiful addition to any garden, but it also has a number of practical benefits. One of the most important is its ability to suppress weeds.

Crimson clover grows quickly and densely, creating a dense mat that crowds out weed seedlings.

In addition, the deep roots of crimson clover help to compete with weeds for moisture and nutrients. As a result, crimson clover can be an effective tool for keeping weeds at bay.

This is especially helpful in gardens because weeds around crops are difficult to control, such as corn or potatoes.

14. Used as a Roadside Cover Crop 

Crimson clover is often used as a roadside cover crop. It is a hardy plant that can tolerate a wide range of growing conditions. It is drought-tolerant and does not require much maintenance.

How to Use Crimson Clover as a Cover Crop

Crimson clover is not a well known cover crop, but it should be. This annual legume seeds in the fall, overwinters, and flowers in the spring.

It fits well into most any kind of crop rotation and can be planted as a main crop, or as a between-crop. Here are some tips on how to grow it.

1. Any Kind of Soil Works

Clover is not demanding and will do well even in sandy loam, which other cover crops find lacking. The exception to this is if your soil is clay-based, waterlogged, or either too acidic or too alkaline.

If any of those are the case, look for another cover crop species or take the time to amend your soil as needed first.

2. Inoculate If You’ve Never Grown Before

If you are planning to use crimson clover as a cover crop, it is important to inoculate it if you have never grown it before.

This will ensure that the nitrogen-fixing bacteria in the soil are able to work effectively. Inoculating crimson clover is easy to do, and there are many products available at garden centers and online.

With a little planning, you can ensure that your crimson clover cover crop will be a success.

3. Improve Alkalinity of Soil and Potassium/Phosphorous Content to Improve Nitrogen Fixation

Crimson clover is commonly used as a cover crop, but in order for it to be most effective, the alkalinity of the soil should be improved and the potassium/phosphorus content should be increased.

This will help improve nitrogen fixation, which is essential for healthy plant growth.

There are several ways to improve soil alkalinity, such as adding lime or wood ash. For best results, a soil test should be conducted to determine the ideal amount of alkalinity-increasing material to add.

Incorporating organic matter into the soil can also help to increase its potassium and phosphorus content.

This can be done by adding compost or manure to the planting area before sowing the crimson clover seeds.

By taking these steps, farmers can ensure that their cover crop will be able to provide the nitrogen-rich environment that their plants need to thrive.

4. Don’t Plant Too Early or it Will Go to Seed and Not Regrow in Spring

One of the most common questions asked about crimson clover is when to plant it. The answer, unfortunately, is not a simple one.

Crimson clover can be planted as early as the last frost date in spring, but if it is planted too early, it will go to seed and not regrow in spring.

Conversely, if it is planted too late, it will not have enough time to establish itself before winter. In general, the best time to plant crimson clover is before the first frost date in fall.

This will give the plants enough time to establish themselves without going to seed. Once established, crimson clover will reseed itself each year and provide a consistent source of cover for your garden.

5. As a Winter Annual, Seed 6-8 Weeks Before Frost

For best results, sow the seeds 6-8 weeks before the first frost date in your area. This will give the plants enough time to establish themselves before winter sets in.

6. Kill Mechanically or Till In if Not Winter Killed

If crimson clover is not winner killed, it can become a weed in subsequent crops. Therefore, it is important to kill crimson clover mechanically or till it in if it is not winner killed.

What Else is Crimson Clover Good For?

Crimson clover is a beautiful flowering plant that is often used as an ornamental cover crop. However, this hardy plant is also known for its many other uses.

For example, crimson clover can be used as a green manure, providing essential nutrients to the soil. It can also be used as mulch or added to compost.

Moreover, crimson clover helps to suppress weeds and can even be used as animal feed.

Whether you are looking to improve your soil health or simply add a splash of color to your landscape, crimson clover is definitely worth considering.

Will Crimson Clover Come Back Every Year?

Crimson Clover is an annual plant, meaning it will only live for one growing season. Once winter arrives and the temperatures start to drop, the clover will die off.

However, before it dies, the clover will produce seed pods that contain thousands of tiny seeds. These seeds can remain dormant in the ground for several years before finally germinating.

As a result, it’s possible for crimson clover to reappear in your garden year after year. If you want to ensure that the clover comes back, be sure to leave some of the seed pods on the plant when you harvest it.

This will give the seeds a chance to fall to the ground and start new plants next spring.

In addition to fixing nitrogen, crimson clover also improves soil health and helps suppress weeds. If you’re looking for a new cover crop to add to your rotation, consider giving crimson clover a try!
