Overwintering Echinacea in Pots and the Ground

Echinacea is a beautiful perennial that can be grown in many parts of the country. It is a hardy plant that can survive cold winters, but there are some things you need to do to ensure it survives. In this blog post, we will discuss how to overwinter echinacea plants so they come back strong in the spring!

How to Overwinter Echinacea in Winter?

Echinacea goes dormant in the winter, so overwintering them is simply a case of protecting the roots, pruning the flowers in fall, and providing them with a small amount of water. Doing this will help your echinacea plants get the rest they need during the cold winter months.

While it sounds easy to do the above there are some important things to keep in mind when overwintering your echinacea plants. I will now discuss some of the key tips and tricks to help you get your echinacea through winter successfully.

When Should I Cut Back Echinacea?

The best time to cut back your echinacea is a complicated one that depends on where you live. In general, the best time to cut back echinacea is in the fall, before the winter sets in. Doing it at this time of year allows the plant to replenish its energy stores and get ready for the cold winter ahead.

I recommend cutting your echinacea from around 3-6 inches above the ground, depending on how tall it is. Make sure to cut back any dead or dying leaves as well, to prevent disease and other issues from affecting your plants.

Some people choose to prune their echinacea in early spring as it gives birds a food source during the long winter months. Pruning in spring means that your echinacea will have a shorter blooming period, but you can still expect flowers in the summer.

How Do I Protect Echinacea Roots in Winter?

Echinacea that is planted in the ground should be protected from frost and other harsh winter conditions by mulching around the base of the plant. This will help keep the roots warm and insulated, while also preventing moisture loss in dry winter weather.

If you are growing echinacea in containers or pots, it is a good idea to move them into a sheltered location during cold snaps. You can also take your pots inside if you want to be extra careful about protecting your echinacea.

If you do bring your echinacea inside, ensure that it isn’t placed next to any heaters or on drafty windowsills, as these can dry out the plants and cause them to die.

Should I Cover Echinacea In Winter?

There is usually no need to cover your echinacea in winter, as they are fairly hardy plants and can usually withstand cold weather. However, if you live somewhere that gets particularly harsh winters with lots of snowfall or extreme temperatures, then it may be a good idea to cover your plants temporarily to protect them from the elements.

The optimal growing zones for echinacea in winter are zones 3-9, so if you live outside of these zones you may need to use a thick tarp or another cover to insulate your plants from the cold. Just make sure to remove the covers once temperatures start warming up in spring so that your echinacea can get plenty of sunlight and begin growing again!

When Should You Water Echinacea In Winter?

As echinacea are native to the American plains, they are used to dry conditions and can actually become damaged if watered too much in winter. In general, it is best to water potted echinacea every other week during the winter, while echinacea planted in the ground should only be watered if the weather is particularly dry.

Snow that falls onto your plant and melts gradually should be monitored, as this is effectively watering your plant. Too much snowfall or rain can damage your echinacea, so it is best to remove any excess moisture as soon as possible.

Overwatering your echinacea can lead to root rot, which is a serious plant disease that can kill your plants. So be sure to only water your echinacea when the soil starts looking dry and keep an eye on it throughout winter so you know exactly how much water it needs.

Echinacea Disease Management In Winter

Potted echinacea is vulnerable to fungus during the winter months, so it is important to be vigilant about preventing disease and taking action if any signs of fungus appear. Botrytis is a common type of fungus that can affect echinacea, so be sure to monitor your plants closely for any signs of this disease.

The best way to prevent botrytis is by making sure that your plant has good air circulation and is not overwatered or overfed. You should also remove any dead or dying leaves from your plant and keep it sprayed with an organic fungicide to prevent the spread of disease.

I apply fungicide regularly during winter to keep my echinacea healthy and strong. Simply mix the fungicide with water and spray it onto your plants regularly to protect them from disease and other issues.

Neem oil is another great fungicide that you can use to keep your echinacea healthy and vibrant throughout the winter. Just make sure to follow all instructions carefully when using these products, and consult a horticulturist or your local garden center if you have any questions or concerns.

Can Echinacea Withstand Frost?

While the stem and flower buds of echinacea may be more vulnerable to frost, the roots and leaves are actually quite hardy and can usually withstand cold temperatures. Echinacea has tap roots that store food and water, so they are able to survive even the harshest of winters.

However, if your echinacea is growing in a pot and you live somewhere with particularly cold or wet weather, then it may be wise to bring it inside for winter. You can also mulch around the base of your plant to help insulate the roots and prevent them from getting too cold.

When Is It Too Late To Plant Echinacea?

Spring or fall are the best times to plant echinacea, as they are seasons when the weather is mild and your plants can get a good start. Give at least six weeks before the first frost when planting echinacea in the fall, and at least four weeks after the first frost when planting in spring.

Planting during winter or summer can be tricky, as the weather is usually too cold or hot for echinacea to thrive. So if you’re looking for the best time to plant your echinacea, look no further than spring and fall!

Does Echinacea Come Back Every Year?

As a perennial plant, echinacea does indeed come back every year. While it may not flower as much in the first few years after planting, eventually your echinacea will become well-established and bloom abundantly every summer.

However, echinacea will only survive every year if it is given the correct care and attention. Be sure to water it regularly, feed it with a good-quality fertilizer, and keep an eye out for any signs of disease or pest infestations. With proper care, your echinacea will continue to thrive year after year!

My own echinacea tends to last 4-5 years before they start to show signs of age. I always look forward to their beautiful blooms each summer, and am always amazed at how hardy and enduring these plants can be!


In conclusion, if you want to ensure that your echinacea thrives and flourishes throughout the winter, then it is important to take good care of it. Be sure to prune the flowers, water sparingly, protect the roots with mulch, and apply fungicide regularly to prevent any diseases or pests from harming your precious plants.

I hope that this post has given you some useful tips and insights into how to care for your echinacea during the winter months. With a little bit of effort and attention, your echinacea can continue to flourish long after the cold weather sets in! Good luck!
