Coneflower Gardening: Best Practices for Cutting Back

Coneflowers are low-maintenance perennials that bring the prairie landscape to your backyard. These drought-tolerant plants are some of North America’s toughest wildflowers and an important food source for wildlife. Although you can take a hands-off approach to coneflowers, cutting them back once a year is beneficial. In this article, we’ll explain when and how you should cut back coneflowers.

When Do You Cut Back Coneflowers? (Essential Guide)

When Do You Cut Back Coneflowers? Key Takeaways

Coneflowers benefit from being cut back once a year in spring or fall. Although these perennials will return each year, cutting them back can stimulate stronger growth. Once coneflowers have finished flowering, cut them to approximately 3 to 6 inches above the soil, depending on the variety.

Is Cutting Back and Deadheading Coneflowers Necessary?

Although pruning and deadheading coneflowers aren’t technically necessary, they can yield plenty of benefits for the plant. As perennials, coneflowers will grow back every year regardless of whether we prune them or not. But cutting them back once a year can help encourage more vigorous growth and a more extended flowering period.

When to Cut Back Coneflowers

Coneflowers should be cut back in either spring or fall to reinvigorate them for the next blooming season. If you want to cut back your coneflowers in the fall, wait until the plants have finished flowering. You can cut them back close to the ground to protect them during the winter.

Cutting back coneflowers at this time yields a more extended flowering period next year. Coneflowers will also readily self-seed once the flowering season ends, which is fine if you want them to spread. But if you want to keep them in check, cutting them back in the fall is best.

You can also hold off on cutting back your coneflowers until the spring after flowering has finished. This allows you to enjoy the seed heads throughout the winter and benefits wildlife. When spring arrives, cut your coneflowers back to approximately 3 and 6 inches above the ground. Remember that cutting back coneflowers in the spring will slightly shorten the flowering season.

You can also deadhead coneflowers throughout the blooming season to encourage the plant to produce new blooms. Check out our essential guide to deadheading coneflowers for more information.

Key Considerations When Cutting Back Coneflowers

Before cutting back your coneflower, you must decide how much of the plant you will remove. This is determined by the size of the plant, which can vary depending on the exact species. Smaller coneflower varieties can usually be cut back harder than larger varieties.

Small varieties such as Echinacea angustifolia grow to about 1 or 2 feet tall. These coneflowers can be cut back to about 3 inches above the soil. Because they are smaller plants, they will grow back faster than larger coneflowers.

If you have a large coneflower variety like Echinacea purpurea or Echinacea laevigata, don’t cut it back as hard. These large species can grow between 2 and 5 feet tall and 1.5 to 2 feet wide. Cut them back down to between 4 and 6 inches above the ground so that they can recover next season.

As well as bringing beauty to our gardens, coneflowers have tremendous benefits for wildlife. During the fall, coneflower seed heads can provide a welcome food source for birds and other creatures. If you avoid cutting back your coneflowers until spring, your local wildlife can enjoy the seeds during fall and winter.

Although coneflowers should be cut back in spring or fall, you can cut them back at other times of year for specific reasons. You can cut back coneflowers to stagger the emergence of flowers during the flowering season. This allows you to enjoy these beautiful flowers for a lot longer.

If you have a lot of coneflowers, it’s worth cutting them back at different times to boost the duration of the flowering season. As usual, cut back your coneflowers in spring to enjoy the flowers as soon as the blooming season starts. Then, cut some back mid-summer to encourage flowering later during the fall when your other coneflowers have finished.

Essential Tools for Cutting Back Coneflowers

Whenever you decide to cut back your coneflowers, using clean, sterile cutting tools is essential. This prevents your coneflowers from being infected by diseases that other plants may carry. Sterilize your pruning shears with a 5% bleach solution before pruning your coneflowers.

It’s also worth ensuring that your tools are sharp before pruning coneflowers. Whenever you prune a plant, making a sharp, clean cut is much better than struggling with a blunt tool. Clean cuts minimize the opportunity for diseases or pests to invade the plant, so sharpen your tools beforehand.

How to Cut Back Coneflowers

There are some best practices to minimize plant damage when deadheading or cutting back coneflowers. You can also prune any diseased or damaged foliage throughout the season to keep your coneflower looking good.


Always use clean, sharp pruning shears to deadhead your coneflowers. Once a flower head begins to wilt, remove it to divert energy into fresh blooms. Cut back to an emerging bud so that the coneflower can keep flowering.


You can keep your coneflowers neat by removing damaged or diseased foliage during flowering. Browning, drooping, or yellowing leaves can be removed individually with sharp pruning shears. Removing affected foliage immediately is crucial if you spot symptoms of diseases or pests.

Cutting Back

Cut back your coneflowers in spring or fall to help revitalize the plant. If you want the best flowering season next year, cut coneflowers back in the fall. If you leave the seed heads during fall and winter, wait until spring to cut the plant back.

Here’s a quick step-by-step guide for cutting back coneflowers:

  1. Ensure your pruning shears are clean, sharp, and sterile before cutting.
  2. Choose how much you want to cut back your coneflowers depending on the plant’s size. Cut it back closer to the ground if it’s a smaller variety. Leave up to 6 inches of stem above the ground if it’s a larger variety.
  3. Make a sharp, clean cut at your chosen point on the stem, leaving 3 to 6 inches above the soil. This helps reduce the risk of your coneflower getting infected by diseases or infested with pests.

Winter Care For Coneflowers

As perennials, coneflowers will go dormant and die back over winter before reemerging the following spring. Your coneflowers will survive the winter without being cut back and left to die naturally. However, cutting them back can encourage more robust and vigorous growth next spring.

Coneflowers can survive winter perfectly well, even if they get covered in snow when cut back close to the ground. Depending on the size of your plant, cut it back to around 3 to 6 inches above the soil. Smaller varieties can be cut back harder than larger ones.

If you live in USDA Zones 3 to 9, you shouldn’t need to provide any extra winter protection for your coneflowers. However, if you live in colder climates with harsh winters, you may need to protect them from the cold. It’s also a good idea to mulch your coneflowers to preserve the roots and help them retain moisture.

Essential Coneflower Plant Care

Coneflowers need hot, sunny conditions to truly thrive and should get six to eight hours of direct sun every day. Plant coneflowers in loose, well-draining chalky, loamy, or sandy soils that are neutral to acidic. Coneflowers are drought-tolerant plants, and mature specimens will rarely need watering. Give coneflowers a small dose of fertilizer or a fresh layer of compost once or twice a year. Coneflowers are also relatively easy to transplant or divide if you ever need to relocate or are looking to expand your collection. 

The Final Word

Coneflowers are excellent low-maintenance plants for any garden and are a great choice for novice gardeners. Although cutting them back isn’t necessary, it helps promote more vigorous growth and a more extended flowering period. Coneflowers should be cut back in spring or fall to about 3 to 6 inches above the ground.
