Coneflowers should be planted in the spring or early fall in full light. Add Miracle-Gro Garden Soil for Flowers to the in-ground soil to prepare it. At the time of planting and throughout the growing season, water plants thoroughly. Use Miracle-Gro Water Soluble Bloom Booster Plant Food to feed your plants.
Do coneflowers need to 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.
How are coneflowers cared for?
Echinacea, sometimes known as coneflowers, is a hardy perennial in the daisy family (Asteraceae). They are indigenous to the eastern and central United States, from Colorado to Texas in the south and the Great Lakes in the north. Here is how to cultivate this native American plant in your garden.
About Coneflowers
These quick-growing plants have a height range of 2 to 4 feet, blossom from midsummer till the first fall frost, and self-sow profusely. Coneflowers are named for their elevated, conical centers that draw bees and butterflies. The seed heads draw songbirds like goldfinches once they blossom. Once they are established in a conventional garden or a meadow of wildflowers, coneflowers enjoy the heat and are trouble-free.
The majority of echinacea species are purple (E. purpurea), but there are up to nine naturally occurring varieties that are yellow or purple (E. paradox). More sizes and colors are available with hybrids, but there are drawbacks as well: many of them lack genetic diversity and are sterile, which means they cannot produce viable seed.
The lower stem of the plant, which is frequently prickly, is referred to by its genus name Echinacea, which is derived from the Latin word for hedgehog, echinus. Coneflowers are so named because their elevated, cone-shaped centers are filled with seeds that draw butterflies. After bloom, leave the seed heads on the plant to draw in songbirds like goldfinches! They are less susceptible to deer than other floral plants since they are native plants with thorny stems.
When grown in large groups, coneflowers are spectacular, especially when they are a combination of different colors.
Coneflowers prefer soil that drains well and direct sunlight. Although coneflowers can thrive in a variety of soil types, nutrient-rich soil is where they bloom at their finest. 12 to 15 inches of loose soil should be added, along with a 2 to 4 inch layer of compost or aged manure. Pick a spot where the coneflowers won’t be shaded out or languish in soggy ground. If the correct circumstances exist, they will spread quickly. (Read up on how to get soil ready for planting.)
When to Plant Coneflowers
Coneflowers are typically purchased as little plants that will soon bloom. Planting time for these should be in the spring, early summer, or fall.
- Coneflowers should be planted while they are young and will bloom in the spring or early summer.
- Eight to ten weeks prior to the last spring frost date, seeds can be started inside. Alternately, plant them outside after the soil has warmed to at least 65°F (18°C). Plants grown from seeds are unlikely to blossom for two to three years.
- Note: Coneflower plants will rapidly self-seed if you don’t clip them back.
- Coneflowers should only be divided or moved in the spring or fall.
How to Plant Coneflowers
- Coneflowers should be spaced 1 to 3 feet apart, depending on the variety’s mature size.
- Dig a hole that is almost twice as wide as the pot if you are planting from one. The root ball of the plant should be level with the soil surface when it is placed. To the top of the root ball, fill in.
- At planting, give it plenty of water.
- To help keep plants wet and discourage weeds, cover the soil top with thin layers of compost, followed by mulch.

Coneflowers can withstand drought, although young plants require water from time to time, and more frequently if the spring is particularly dry.
- To help keep the plants wet and discourage weeds, mulch and compost in thin layers should be placed around them.
- Fertilizer is rarely needed in native soil. When you plant, make sure your soil has a lot of organic matter.
- If the spring is particularly dry or your coneflowers are recently planted, just add extra water in the late spring.
- When flowers start to fade, deadhead to extend the bloom duration. Trim stems to a leaf close to a bud. Late-season deadheading stops self-seeding and bird feeding.
- Optional: When coneflower plants bloom, prune them back by a foot to promote delayed blooming for fall enjoyment. Because coneflowers have a tendency to become lanky, this will result in later blossoming and more compact growth. For more evenly spaced bloom heights and periods, cut certain flowers but not others.
- August could bring on beneficial army beetles that resemble wasps. They pollinate plants and eat bug eggs and larvae. Avoid hurting them.
- In cooler areas, scatter mulch around plants in the late fall.
- When stems wilt or after a hard cold, trim them back to the soil line. Cut back in the late winter to encourage self-seeding. When cleaning up the garden in the late winter or early spring, prune back the plants.
- Optional: Think about allowing late-season flowers to develop on the plants. Birds will be drawn to the seed heads, which will encourage self-seeding. If you prefer not to have self-seeding, deadheading will stop it. Cut the dead flower back to a leaf where you can see a bud that is about to swell in order to deadhead.
- Coneflowers can be divided or moved in the spring or fall.
Growing Coneflowers in Pots
Coneflowers are often grown in the ground as perennial plants, but you can grow them in pots if the pots are deep enough to accommodate the plant’s taproot. Use containers with drainage holes that are at least 2 or 3 gallons in size. For drainage, spread crushed gravel in the pots’ bottoms. With potting mix, halfway fill the pot. Slow down. Spread the roots out and plant the root ball an inch below the container’s rim. Gently press down the soil after adding it gradually until it is level with the top of the root ball. Deep breathing.
- Place pots in full morning sun and half afternoon shade after keeping them in partial shade for two to three days.
- Always deeply water the soil when it feels dry to the touch. There is a risk of fungus from water on leaves.
- Every few weeks, fertilize the soil with a water-soluble 10-10-10 product.
- For sustained flowering, remove the dead flowerheads slightly below the flower’s base.
- When plant development slows in the fall, trim plants to the soil level to overwinter them.
- Move to a spot with low to moderate indirect light and a cool (40 to 50 °F) temperature.
- Every few weeks, check the soil and water it lightly if the top 3 inches are dry.
- If new growth starts to sprout in the spring, relocate to a warmer (60 to 70 °F) and more sunny spot. Moving the plant aids in preparing it for life in the spring and summer outdoors.
- Avoid watering leaves from above since this can promote fungus on the leaves. Instead, hydrate the soil. If you notice any bugs or aphids, use a neem oil solution spray or an insecticidal soap.
- Dividing and repotting echinacea plants every three to four years following the start of new growth is recommended.
- Echinacea purpurea cultivar “Robert Bloom” features pronounced, dark orange centers and vivid scarlet flower petals.
- The dark mauve flower petals of Tennessee coneflower (Echinacea tennesseensis) have greenish-pink cores.
- Echinacea purpurea’s “Finale White” variety includes flower heads that are creamy white with greenish-brown cores.
- The soft-yellow petals of the hybrid echinacea “Cleopatra” have golden-green cores.
Are coneflowers contagious?
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 are coneflowers prepared for 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.

If deadheaded, do coneflowers bloom again?
Coneflowers’ rebloom can be prompted by deadheading. Black-eyed Susan must be deadheaded if you want dependable repeat blooming all summer and into fall, while purple coneflower and yellow coneflower will rebloom without it.
Self-seeding can also be avoided by removing wasted blooms. Deadhead plants before the seed heads ripen if you don’t want them to spread over the garden. As soon as a flower has completed blooming, remove it from the garden to keep it looking tidy.
Use sharp shears or pruners to cut the blooms off coneflowers because they have sturdy stalks. If a bloom is already dead, simply make a clean cut just above the first set of leaves beneath the flower to remove it. Pruning tools should be cleaned by soaking them in a solution of one part home bleach or pine oil cleanser mixed with three parts water for five minutes before using. Prior to use, rinse with clean water.
How can coneflowers be made bushy?
Echinacea plants don’t need any additional feedings when they are grown in good, rich soil. These plants may eventually turn lanky if they receive excessive fertilizer. However, they will gain from compost applications made once a year in the spring. Your plants’ foliage and blossoms will look healthier thanks to the compost’s great nutrient boost.
The best time to prune your Echinacea plants is in the spring if you want to achieve a generally bushy appearance. Your beauties’ blooming season will be extended by this procedure, which will assure their healthy growth. These plants can also have all of their dead flowers removed to allow place for new ones to bloom.
How should coneflowers be handled after blooming?
Coneflowers can also be pruned in the summer. Pruning, meanwhile, does not appear the same in the summer as it does in the spring or fall. When you prune in the summer, it is more akin to “dead heading” and bouquet-making trimming. Unlike in the fall or spring, you won’t want to completely prune your plant.
In order to deadhead your coneflowers in the summer, you must remove bloom-expiring flowers. Deadheading is frequently done to maintain the plant’s appearance, stop seed production, and promote new blooms on the plant.
Did you know that cutting the flowers will increase the amount of blooming in many coneflower species? It’s true that cutting your flowers to enjoy indoors can frequently lead to even more blooms all summer long. So pull out the scissors and enjoy the lovely blooms both inside and outside.
How old are coneflowers on average?
All Echinacea species, with the exception of Echinacea purpurea, are deciduous herbaceous perennials. Echinacea grow in clumps that slowly increase and can be divided every few years to keep their vigor. Echinacea of the wild kind are often 2′ broad and 3–4′ tall. However, the eastern taxa are often smaller than the high-plain taxa from Texas to Canada. Modern hybrids range in height from less than a foot to three feet and are two feet wide. A single plant can live up to 40 years in the wild. Every four years is the ideal time to divide them in the garden.
Echinacea flowers, like all plants in the Asteraceae family, are actually inflorescences, which are made up of 200–300 disk florets, which are small, fertile florets that are grouped together on the cone. A ring of sterile ray florets, or what we call petals, surrounds the disk florets. The width of the entire inflorescence can range from 2″ to 5″. The ray florets’ main function is to draw pollinators to the disk florets, where pollination takes place, using their vibrant colors. A coneflower plant’s disk florets do not all release pollen (reach anthesis) at the same time, as may be seen by paying close attention to the plant. Over the course of many days, the florets in the center of the disk open first and then move outward in succession. You may use this procession to gauge how much longer your bloom will live by watching it.
The disk florets might be black, white, yellow, dark burgundy, or orange. Echinacea ray flowers typically have pinkish-purple or, less frequently, yellow or white florets. Petal colors including orange, peach, salmon, and reddish-orange can now be found in newer hybrids, which have overcome this color barrier. The petals of wild-type echinacea can be held outward, but they are typically reflexed to varied degrees downward. Although the petals might be broad and overlap one another, they are often thin with room in between. Modern breeders have made strong selections for hybrids with outward-held, broad, overlapping ray florets. While Echinacea simulata and several contemporary hybrids have exceptionally sweet scents, the wild-type Echinacea purpurea frequently has only a faint aroma.
A robust, rigid, hirsute (hairy), typically unbranched stem (peduncle) that is at least 36″ tall holds the inflorescence. Cultivars with spectacular, widely-branched flower stalks, including Echinacea ‘The King’ and Echinacea ‘Elton Knight,’ are the exception to the rule of the unbranched stems. Along the length of the flower stalk, there may be tiny leaves that are widely spaced. produced in a profusion of overlapping inflorescences beginning in July and lasting until the first frost. Up to a dozen inflorescences may be open at once as a result of the overall effect.
