Red Clover: A Cover Crop & Herb

Red clover (Trifolium pratense) is an herbaceous biennial plant native to Europe that has naturalized throughout North America. While some consider red clover a weed, herbalists, and gardeners recognize its value. This beautiful plant is excellent for soil and human health. Here are some of the reasons we’re big fans of red clover and how we use it. 

Red Clover as a Cover Crop

Red clover is a nitrogen-fixing cover crop. It’s an excellent choice for adding green manure to build up soils and a good nectar source for some pollinators. You can sow it in fallow fields, pathways, and small openings to help suppress weeds. 

You can sow red clover in early spring, late summer, or fall as a winter cover crop. It can be a little slow to establish, so sow clovers at least 40 days before your average first frost.

Consider using buckwheat as a nurse crop if you’re sowing red clover during the hotter months. The clover will grow slowly under the buckwheat until fall frost kills the buckwheat, allowing the clover to establish quickly without the need for fall tilling.Bumblebee on a red clover blossom

Red Clover in Herbal Medicine

I’m not a doctor. This article is for informational purposes only. Consult a physician or clinical herbalist before using herbal remedies to treat any condition. 

Herbalists have used red clover for centuries to treat a wide range of conditions, from menopause to whooping cough. Many of its uses revolved around female health. Modern science is beginning to explore the properties of plants, including red clover. While further research is needed, red clover tea and tincture may have a few potential benefits.

Benefits of Red Clover

  • Red clover contains phytoestrogens, which can mimic estrogen in the body.
  • Red clover may reduce osteoarthritis symptoms related to menopause. A 2015 study of 60 women found that taking red clover extract over 12 weeks reduced bone mineral density loss in the spine.
  • In another study of 109 postmenopausal women, participants reported skin and hair texture improvements after taking red clover extract for 90 days.

Further research is needed in all of these cases. Don’t use red clover if you have a hormone-sensitive condition like breast cancer. 

Harvesting and Using Red Clover

Beyond its health benefits, red clover is also just an enjoyable herb to use. Both the leaves and the flowers are edible. Some of you may remember pulling the pink blossoms from the flowerhead and eating them as a kid. 

The leaves, which have a mild bean-like flavor, can be added to salads. The blossoms, which are sweet, can be used in tea, baked goods, or salads. It’s best to break them up or pull the tubular flowers from the flowerhead, as whole flowerheads can be dry and tough to chew.

Harvest leaves and flowers that look fresh and are free from dried, brown spots. Remember to leave some blooms for the pollinators, especially if you’re harvesting from wild patches.

Making red clover tea is simple: Pour about 2 cups of boiling water over about 1/4 to 1/2 cup of fresh or dried red clover blossoms and let it steep for 10 to 15 minutes. You can also let it cool and pour it over ice to make a fun summertime herbal iced tea. 

Red clover mixes well with other flavors. Feel free to experiment with adding lemon balm, mint, white clover, chamomile, or orange slices to the mix and sweeten with honey or maple syrup to taste.

Red Clover Tincture

Using the folk method, you can make a basic red clover tincture with fresh or dried red clover blossoms. All you need is a few simple ingredients and some patience. 

You simply place the blossoms in a glass jar and cover them with 80-proof alcohol. Then, keep the tincture somewhere dark for 2 to 6 weeks, shaking it once a day. After this period, you can strain it and begin using it.

Red clover is a fun herb to grow and use. Try growing it as a cover crop in your garden this season and enjoy its many soil health, culinary, and herbal benefits. 

Fall Cover Crops & Their Importance

Fall is actually one of the best times for backyard gardeners to work on improving their soil health. Without a lot of effort gardeners can improve the soils through the fall, winter, and early spring for a better gardening season next year through the use of cover crops. Cover crops are not just for large farms and have a variety of benefits.

Benefits

Reduce Erosion

First off, using a winter cover crop is extremely important in resducing erosion. When there’s nothing growing in the soil in fall, winter, and early spring any rain or melt water can erode valuable soil and nutrients and pollute the local water system. Too many nutrients in the lakes, streams, and river can cause algae blooms that can be dangerous to both people and aquatic life.

Add Organic Matter

As cover crops die or are tilled into the soil they add organic matter which is key to soil health! It gives the soil structure, retains moisture, provides habitat and food for beneficial insects and microbes, and adds nutrients to the soil as it slowly breaks down. If not tilled in the pant material also functions as a mulch to continue to suppress weeds, preserve moisture, and reduce ersosion.

Conserve Moisture

In the same way that open soil is vunerable to ersion it’s also vunerable to evaporation.  Cover crops prevent sun and wind from drying out the soil and hold rainwater.

Some Fix Nitrogen

Any cover crop variety that is a legume actually adds nitrogen to the soil as it grows in addition to the nutrients it provides when it dies or is tilled under. Some examples SESE carries will be given below.

Suppress Weeds

Cover crops also help to suppress weeds. Most cover crops are quick growing and vigorous allowing them to outcompete and knock back weeds.

Help Pollinators

Often your fall cover crops will be one of the first plants blooming in the spring, a critical time for pollinators. Planting in the fall gives you and them a jump start. They’re provided a reliable food source early helping you ensure reliable pollination throughout the growing season.

Fall Cover Crop Varieties

Southern Exposure offers a variety of cover crops suitable for fall planting.

Hairy Vetch

Hairy Vetch is both beautiful and useful. Bees and other pollinators love its purple flowers. It’s also a nitrogen fixing legume. Sow August 1st – November 1st.

Austrian Winter Peas

This awesome crop can be grown through the winter in zones 6 and up. It’s nitrogen fixing and edible! Sow August 15th – November 1st.

Buckwheat

Buckwheat isn’t really a winter cover crop becuase it’s what is called a “winter-kill crop” meaning that it dies back with the fall frosts. However it’s great for planting in the fall with a mix of clover because it provides clover shade and cool soil until it dies allowing th clover to take off. It can be planted in the spring up until 1 month before the last fall frost.

Crimson Clover

This nitrogen fixer does best where winter temperatures don’t dip below 10°F. It has longer blooms than traditional red clover. Sow from mid-July through mid-September.

Red Clover

Red clover has a lot going for it. It’s well loved by pollinators, fixes nitrogen, is great for weed supression and makes a wonderful, medicinal tea. Sow in spring or fall.

White Dutch Clover

Like the other clovers White Dutch is excellent for nitrogen and supressing weeds. Sow in late winter, spring, late summer, or fall.

Hulless Oats

Hulless Oats make an excellent cover crop for adding a lot of organic material. It should be noted that they will winter kill in areas where the temperature drop below 10°F. Oatstraw stems can be harvested for tea. Sow in later summer for a winter cover crop.

Common Winter Rye

While Winter Rye is not nitrogen fixing it’s still an excellent cover crop. It can actually help stabilize excess nitrogen and releases phosphorus and potassium from the soil for plants to use. It’s extensive root system makes it excellent for improving soil structure. It’s also vigorous and great for weed supression, erosion reduction, moisture conservation, and adds tons of organic material to the soil. Sow August 1st – November 15th.

Just because the gardening season is coming to a close doesn’t mean there’s not still planting to be done. If you want a healthy productive garden next year it’s definitely worth the effort to plant a cover crop this fall!
