The perennial echinacea is resilient and can withstand extremely chilly winters. In the winter, plants go dormant and emerge in the spring.
How resistant to cold is echinacea?
This hardy perennial will provide you with years of spectacular flowers with little maintenance. The following advice will demonstrate how to take care of purple coneflowers.
Sunlight needs for Echinacea
This perennial really enjoys the heat. Coneflowers should be grown in full sunlight so that they receive at least 5 hours of direct sunlight each day. The plant can take light shade, but it thrives in full sunlight because plants cultivated in darker areas like to “stretch for the sun.”
Moisture and Soil requirements for Coneflowers
The coneflower plant can withstand droughts pretty well, although it prefers good soil that drains well. But it can handle bad soil fairly nicely. Although it can survive in arid environments, it prefers to receive approximately an inch of rain every week. You will need to give the plant more water if your area receives less rainfall than this.
Although coneflowers appreciate a small amount of organic matter when planted, avoid adding too much. This may lead to the plant having very thick, emerald-green foliage but few blooms. The pH of the soil should be between 6.5 and 7.
Pests and Diseases
Coneflowers require little maintenance and are not frequently afflicted by diseases, but they occasionally succumb to leaf miners, powdery mildew, gray mold, or vine weevils. Most fungus illnesses can be controlled by cultivating the plants in areas with adequate ventilation.
Coneflowers are another one of the Japanese beetles’ favorite plants. Knock the beetles off into a pail of soapy water if the infestation is not too bad.
Cold Hardiness
Although purple coneflowers (and other types) can withstand drought, they can also withstand cold temperatures rather well. Most types may be grown in most parts of the USA because they are cold hardy in zones 3 to 8.
The first winter the plant spends in your garden may require some care, but after that they are hardy and resilient.
What is the ideal location to grow echinacea?
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 does echinacea survive the winter?
Echinacea is simple to grow once it is established in the landscape, but growing it can be difficult at times, especially when it comes to overwintering. Here are some pointers for effectively overwintering echinacea.
The majority of the echinacea we transport in the spring overwintered here in bare-bones homes. Here are some advice from our farmers on how to effectively overwinter echinaceas if you are receiving them in the fall.
Temperature
Keep them at a steady temperature of 45 degrees F in our 50mm Elle Plugs or 38 to 40 degrees F in gallon containers. Larger containers are typically preferable for overwintering echinaceas.
Disease Management
We advise performing one preventative fungicide drench right after transplanting and then another drench approximately 14 days later if you intend to pot the plants up into 1-gallon containers, grow them on for a while, and then let them go dormant. This will safeguard the plants when they enter dormancy. As the plants begin to become dormant, be careful to keep an eye out for botrytis and keep the dead leaves off the plants. By keeping an eye on when and how much the plants are watered, botrytis can be reduced to a large extent.

Do I prune my echinacea throughout the winter?
By the fall, many perennial herbaceous plants have run their course and are starting to lose their blooms and old foliage. The old leaves should be pruned back to the ground now. The plant’s crown, or base, will remain dormant throughout the winter and sprout new shoots the following spring.
Dying stems will benefit from being severely pruned back because they can become damaged to the crown and roots if pounded by autumn and winter gales. By doing this, messy clumps can also be cleaned up. Autumn pruning and cleanup of leaves can also aid in preventing fungus issues. Dead and rotting foliage, which can also house pests like slugs, can serve as a wintering place for diseases.
But that does not mean that all perennials need to be thinned out. These days, many gardeners choose to leave certain perennials intact, especially those with beautiful seedheads since they offer interest in the winter and give wildlife essential food and shelter. In the spring, when new growth begins to show at the base and they begin to appear untidy, they can be pruned back.
Many gardeners these days choose to leave some perennials whole, especially those with eye-catching seedheads.
Cut down old flower stems
Pruning with wasted flower stems removed is the most basic kind. Since these are frequently hollow, cut them as low and angularly as you can to prevent water from collecting within and freezing, which would harm the crown. If the base of the cluster has already developed new growth, cut just above it.
Prune clump-forming perennials
In the fall, cut perennial clumps like alchemilla, astrantia, and hardy geraniums down to the ground. To prepare the plant for winter, remove all the dead leaves with secateurs. This technique can be used in the fall to tidy up any perennials and grasses that die back.
Leave attractive seedheads
Perennials with attractive seedheads or stems, such as ornamental grasses, thistles, and umbellifers, shouldn’t be cut down since they give structure and appeal over the winter and provide essential food and shelter for wildlife. Find plants with beautiful seedheads.
Perennials to leave
The dense clump of basal leaves that some perennials, including Pulmonaria, retire to should be left alone. Leave perennial evergreens like epimedium, euphorbia, and hellebore. Penstemons shouldn’t be pruned until spring since the old stems will shield the crown from winter frost.
Does echinacea reappear each year?
Yes, because echinacea is such a prolific self-seeder, it will come back every year and frequently in the most unexpected places.
The perennial echinacea is resilient and can withstand extremely chilly winters. Plants go dormant in the winter and reappear in the spring; you should prune them back at this time for the summer.
An important component of the appeal of these perennial favorites is the ease with which they can be grown.
Does Echinacea Need Deadheading?
Despite the fact that the majority of us would want to spend the entire day in our gardens, real life interferes. Instead, we choose simple, low-maintenance plants that, despite only requiring a few minutes here and there of care, give the impression that we spent hours in the garden. Coneflower is a plant that I frequently recommend since it can withstand poor soil, extreme heat, drought, full sun to part shade, and it blooms continually whether you deadhead it or not.
Aren’t coneflowers sounding quite good right now? Getting better Echinacea attracts and feeds pollinators and a variety of butterflies when it is in bloom (such as Fritillaries, Swallowtails, Skippers, Viceroy, Red Admiral, American Lady, Painted Lady, and Silvery Checkerspot).
After they stop blooming, their seed-covered “cones serve as a valuable source of food for many birds from late summer to winter (such as goldfinches, chickadees, blue jays, cardinals, and pine siskins). Therefore, when people ask me about deadheading Echinacea plants, I normally advise them to only do it during the flowering period in order to keep the plant looking lovely, but to leave fallen flowers in the late summer to early winter for the birds.
In order to stop Echinacea from reseeding itself all over the garden, you can also deadhead it. Older forms of coneflower can self-seed, though not quite as aggressively as Rudbeckia. Newer hybrids typically do not self-sow and do not generate viable seed. Birds aren’t really interested in these more recent hybrids either.
Should I reduce my fall Echinacea planting?
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.
Does echinacea thrive in containers?
As long as they have enough space to grow, lovely echinacea flourish in both garden borders and pots. They should be planted in a deep container that is placed in an area with lots of sunlight.
Growing echinacea in containers is definitely a better option if your soil is thick clay and susceptible to becoming soggy. Use a multipurpose potting compost with lots of horticultural grit for free draining, like John Innes No 3.
Since containers tend to dry out much more quickly than garden beds, it’s good news that echinacea are naturally drought tolerant plants. However, you don’t want them to dry out too much. When the soil’s surface starts to dry out, water them.
Choose the largest container you can to reduce the amount of watering required and to give the plant plenty of area to grow.
