Coneflowers are drought-tolerant and winter-hardy plants. It is only required to water a coneflower that has been buried during the winter if the winter has been exceptionally dry. Other than that, no extra water is required.
Coneflower in a pot, however, frequently needs watering in the winter. If the top few inches of the soil are dry to the touch, water your potted coneflower sparingly every other week because containers and planter boxes dry up much more quickly in the winter than the ground. Coneflowers dislike having their feet wet, so take care not to overwater or allow the soil to become damp.
Coneflowers will they return each year?
- Before cutting down to the ground to get ready for fresh growth in the spring, let plants stand through the winter to provide food for wildlife.
Coneflowers are a must-grow if you appreciate watching pollinators buzz and flit about lovely, trouble-free flowers that bloom for a long time. Although purple coneflowers (Echinacea purpurea) are the most prevalent, there are many new coneflower cultivars available in a rainbow of cheery hues, including pink, yellow, orange, red, and white. These flowers don’t just provide joy for a short time; they return year after year because they are perennials.
Because of the “cone that starts to poke up in the center of the circle of petals as each flower matures, coneflowers get their name. Actually, this is a group of seed heads that, when allowed to dry on the plant, serve as Mother Nature’s bird feeder, luring a large number of cardinals, goldfinches, and other hungry birds.
How to Choose Coneflowers
Which of the dozens of different coneflower kinds should you grow? The quickest response is: whichever ones you deem attractive and have room for (check the plant tag for info on this). Want some recommendations? Use these
- There are numerous native coneflower species, but the purple coneflower, which typically reaches heights of 2 to 4 feet, is the most well-known.
- ‘White Swan’ is a well-known variety that grows up to 4 feet tall and has big white blossoms among other widely available types.
- A lot of dwarf coneflower types, like “Kim’s Knee High,” remain fairly compact (with pinkish-purple flowers). If you have a small garden, consider planting them because you will get many blossoms in a short amount of space.
- Coneflower variants are also available that hardly resemble coneflowers at all, notably hybrid double types with two rows of petals. Just be mindful that some of plants produce flowers that fade more quickly than others in the garden.
Where to Plant Coneflowers
Coneflowers should be planted in an area with at least 6 to 8 hours of sunlight per day. However, in warmer climates (zones 8 and higher), a little midday shadow is beneficial because it will prevent the blooms from fading. As a result of their clump-forming nature, these plants won’t spread as widely as some other perennials. If you leave blossoms in situ, many of the older kinds may self-seed, which is a simple way to grow new plants!
When to Plant Coneflowers
Coneflowers grow best in the spring, after all threat of frost has passed. You can plant in the early fall as well. Just make sure your new plants have at least 6 weeks before the first anticipated frost to form roots; otherwise, they might not reappear in the spring.
How to Prepare the Soil for Planting Coneflowers
Coneflower roots need a healthy environment to flourish, so strengthen your natural in-ground soil by adding 3 inches of Miracle-Gro Garden Soil for Flowers to the top 6 inches of soil. The Moisture Control technology in this nutrient-rich garden soil helps to safeguard plants when they unintentionally receive too much or too little water. Additionally, if you use Miracle-Gro soil and plant food (and adhere to all instructions), you’ll get up to three times as many blossoms during the growing season (compared to unfed), so be sure to read the part below on “How to Feed Coneflowers.” Just one coneflower planted? Make a hole, then mix garden soil and the recently excavated earth 50:50.
How to Plant Coneflowers
1. Determine the location where you’ll plant your coneflowers, making sure to allow enough room between each plant. (The plant tag ought should indicate how much room you need.)
2. Create a hole for each plant that is identical in depth and width to the root ball.
3. To give root growth a boost for the first 30 days, drop a Miracle-Gro Quick Start Planting Tablet into the planting hole (as per the instructions on the label).
4. Remove a coneflower plant from its pot and insert it into the gap. The top of the root ball should be level with the surrounding soil.
5. Fill in the area surrounding the plant and firm up the dirt there.
6. Water sources.
7. Spread a 3-inch layer of mulch around the plant, being careful not to let it contact the stem, to help keep the soil moist and to block sunlight so weeds can’t develop.
How to Stake Coneflowers
Coneflowers rarely need to be staked because of their sturdy branches and large flowerheads. However, if you do encounter floppy plants, drive a strong stake close to the middle of the plant (avoid going through the plant), and then loosely wrap twine around the stake and the individual stems. Or, you might spend money on a spherical flower clumping stake. In either case, the finished product should appear natural, not constricted around the plant’s middle.
How to Water Coneflowers
Coneflowers can tolerate drought pretty well once they’ve had some time to establish themselves. Check on them every other day after planting; if the top inch of soil is dry, thoroughly water. Your coneflowers’ droopy leaves are another indication that they need water. Coneflowers shouldn’t require watering after a full growth season in the garden unless it hasn’t rained in at least two months.
How to Feed Coneflowers
Want a ton of lovely flowers? As soon as fresh leaves begin to grow in the spring, begin feeding your coneflowers Miracle-Gro Water Soluble Bloom Booster Plant Food. Your plants will grow bigger and produce more blooms as a result of this flower feast, which gets to work right away. Additionally, since you may apply water-soluble fertilizer when watering, it won’t require any extra time to do so.
How to Deadhead and Prune Coneflowers
Deadhead coneflowers frequently at the start of the bloom season to promote greater flowering by removing the faded blossoms before they set seed. Always prune back to a leaf or section of the stem where a new bud is visible. You can just leave them alone later in the season when the plant starts to produce fewer blooms.
To feed the birds over the winter, let the plants alone. Prune them to the ground in late winter. In the early spring, leaves will appear at ground level, soon to be followed by flower stalks.
Try this simple trimming tip to prolong the blooming period of your plants’ coneflowers by at least a season. Cut back some of the stems by half as they start to grow again in the spring to postpone flowering on those stalks. The cut stems will lend their beauty a bit later in the season after the uncut stems have finished blooming.
Can I Divide Coneflowers?
While some perennials need to be divided in order to keep on thriving, coneflowers do not. They are difficult to divide because each plant has a single taproot. Therefore, simply let them be.
Coneflower can withstand how much cold?
According to the Lady Bird Johnson Wildflower Center, moist stratification promotes the optimal germination of purple coneflower seed. The seeds can be kept wet without preventing later germination by mixing them with a tiny amount of sawdust, vermiculite, or peat moss inside a plastic zipper bag or small jar for cold stratification.
In containers filled with damp potting soil, seeds are placed one-quarter inch deep and covered with plastic to keep moisture. These containers are placed in a refrigerator or another space with a constant temperature range of 33 to 60 F throughout the stratification process. Experts generally recommend temperatures between 40 to 59 F for E. purpurea coneflowers, with the majority at the lower end of the scale.
Gardeners in regions with steady winter temperatures in this range can set trays outside. Oftentimes, pre-stratified seed that is packaged does not need to be chilled before germination.
Coneflowers are pruned back for the winter.
What time of year should coneflowers be pruned? Depending on your garden objectives and pruning strategy, the answer to this question may change. For further information on when you should go to your plant with the shears, see the seasonal recommendations below. Keep in mind that some pruning may occur both during the active growing season and during the dormant period.
Fall/Winter Pruning
Coneflowers can be pruned after they become dormant in the late fall or early winter if you choose to keep your garden neat during the colder months. In the fall, trimming back the dormant stalks and seed heads will lessen the likelihood of the plant naturalizing, or spreading. If the seed heads are not trimmed back, native prairie coneflower species, such as Ratibida columnifera and Ratibida pinnata, will easily spread via seed. Pruning in the fall is for you if you have a little garden that you like to maintain neat.
Spring Pruning
On the other hand, I frequently advise delaying the pruning of native plants like coneflowers until the spring for a number of reasons. First of all, during the fall and winter, these flowers offer vital nutrition to the local avian population. You’re helping the local wildlife by letting the seeds stand if your garden is big enough to support some naturalizing by native plants like coneflowers. Additionally, while some gardeners may view the spreading of plants as a drawback, others consider it as an advantage—free plants! Last but not least, seed heads add aesthetic interest to your environment during the winter, when most plants are dormant.
It is ultimately up to you and what you want for your garden whether you decide to prune your plants in the fall or the spring. Moreover, if you have a lot of coneflowers in your yard like I do, you can decide whether to prune part of them in the fall and leave others for the spring.
Will coneflowers in pots last the winter?
Simply plant the seed in the container in the fall and leave it outside to start your coneflowers from seed. As a result, the stratification that the seeds require to germinate will naturally occur. If you are transplanting a seedling, be sure to keep the soil level—you don’t want to bury the crown.
Coneflowers growing in containers should be fertilized with 10-10-10 fertilizer. Put the container in a spot that gets direct sunlight.
Coneflowers can be grown in pots down to USDA zone 5, as they are hardy in zones 3 to 9. For additional winter protection, you can bury the container in the ground or mulch all around it.
How are coneflowers prepared for the winter?
Due to their hardiness, coneflowers are among the easiest perennials to care for throughout the winter. The only thing left to do is watch them resurrect in the summer rather than pruning them back in the fall or spring.
- Decide whether to prune your coneflowers in the spring or the fall. Either method works, but leaving them up over the winter gives nearby birds access to seeds.
- Cut your coneflowers back 3-6 inches from the ground if you decide to prune them in the fall.
- Coneflowers planted in the ground should only be watered during unusually dry winters. Every other week, or as soon as the top few inches of soil feel dry to the touch, lightly water potted coneflowers.
- Coneflowers should be pruned down 3-6 inches from the ground in the early spring if you leave them up during the winter.

Coneflowers can they spread?
Echinacea needs full to partial sun to grow well. At least four hours of sunlight every day are required for plants. Since the plants are native to woodland borders, they will flourish in locations with morning shade and afternoon light, or the opposite.
Echinacea may thrive in rocky, poor soil, but not in soggy, waterlogged soil. Compost should be used as a mulch around newly planted plants.
Coneflowers grow in clumps and require space. One plant will typically grow bigger, but it won’t spread through roots or rhizomes and take over the entire garden. Check the mature size stated in the plant description to help you choose the appropriate spacing because the final size of the plant clump depends on the cultivar. Leave 18 inches between plants if it is anticipated that they will spread to be 18 inches broad. Echinacea must be planted where you want them since they have deep taproots. They dislike being relocated after being established.
Echinacea plants should be planted in well-drained soil in full to part sun in the spring or the fall. Echinacea is also simple to cultivate from seed, but it needs a period of stratification—a cold, damp time—in order to germinate. In the fall, scatter seeds widely (after hard frost in the north and prior to winter rains elsewhere), lightly covering them to deter birds from eating them. In the spring, seeds will begin to sprout. One benefit of starting with transplants is that the majority of plants will bloom during the second year.
How should my echinacea plant be cared for over the winter?
Guide to Growing Echinacea
- Miscellaneous
- soil that is rich and nearly pH neutral.
- In mild regions, there is full sun; in hot climes, there is moderate midday shade.
- The perennial echinacea is resilient and can withstand extremely chilly winters.
- Every winter, cover the dormant plants with thick compost.
Should coneflowers be deadheaded?
Always use a clean pair of sharp pruning shears when pruning or deadheading any plant. Echinacea stems are too thick and coarse to be pinched and require a clean, precise snip with pruners, in contrast to many annuals and perennials that may simply be pinched back by snapping the spent flower head off. Before trimming, sanitize pruners in a solution of rubbing alcohol, bleach, and water to reduce the possibility of disease transmission from plant to plant.
Follow the stem from the blossoms down to the first set of leaves and cut just above these leaves to deadhead wasted blooms. In the event that the plant variety only produces one flower on each stem, you can also cut the stem all the way down to the plant’s crown. The majority of coneflowers have many flowers on each stem and will rebloom even without deadheading.
At leaf nodes, fresh blooms frequently develop before the top flower has finished wilting. In this situation, cut the stalk and spent flower back to the fresh blossoms. In order to prevent the plant from having strange-looking naked stems all over it, always clip the spent flower stem back to a set of leaves or a fresh flower bud.
Stop deadheading wasted blooms in the late summer or early fall so that birds can consume the seed throughout the fall and winter. Coneflower petals can also be used to prepare herbal drinks that fight off winter colds. You can also collect a handful of the fall blossoms to dry.
