When To Split Coneflowers

Although you can divide at any time, early fall or early spring are often the best times. The soil is still warm enough in the fall for plants to grow strong roots before the winter months arrive. Although the temperatures are mild enough to allow the plant to begin developing before hot weather, the soil is still on the cold side in the spring.

Even though echinacea is drought resistant once it is established, you still need to water it frequently until it has grown deep roots.

Do coneflowers require division?

Coneflowers (Echinacea spp. ), which have vibrant daisy-like blooms and can draw bees and butterflies, are a great addition to sunny gardens. Depending on the species you choose, these perennial plants can grow in U.S. Department of Agriculture plant hardiness zones 3 through 10. Coneflowers benefit from being divided every three to four years, despite their drought tolerance and low maintenance needs. It’s critical to pick the correct season to transplant your plants to ensure their survival.

How are coneflowers divided and moved?

Your coneflowers seem to be getting rather large. While the remainder of the plant appears healthy, are the cores dying? You might consider dividing your Echinacea purpurea. Even though splitting a plant in half may appear weird, dividing perennials is relatively simple. You may effectively divide your plants using my step-by-step instructions and video!

Every three to five years, Echinacea purpurea can be divided. Dig up the root mass in the early spring or the late fall. The root mass can be divided into two or three pieces with a shovel, pruning saw, or gardener’s knife. Place the pieces inside a damp towel. The root fragments should be planted right away at the same depth as they were taken, then watered.

When should coneflowers be transplanted?

Coneflowers are best moved or transplanted in the early spring, when the earth is just starting to warm up and soften. In the early fall, when temperatures are cooler and the sun is not as intense as it is in the summer, they can also be transplanted. Coneflower transplanting should not be done in the summer.

After allowing them to mature for around three or four years, you can divide your coneflowers and transfer them. Or, you can frequently transfer a whole plant from one location in your yard to another. You should have no trouble replanting your coneflowers as long as you take care to do it at the appropriate time of year and are able to obtain enough of the healthy root system for a successful transplant.

Coneflowers generally tolerate drought because of their extensive tap roots. The roots of Echinacea purpurea have been found to extend five feet deep! Coneflowers should be divided and transplanted after being dug up as deeply as possible to preserve as much of the root system as possible. Although you won’t be able to collect the entire root system, your transplant should be fine as long as you can get around a foot of root development.

Once you have separated and prepared to transplant your coneflower plant, proceed as instructed in the “Steps to Plant Coneflowers” section above.

Should I prune coneflowers back for the winter?

  • 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?

Coneflowers don’t require dividing like some perennials do in order to thrive. They are difficult to divide because each plant has a single taproot. Therefore, simply let them be.

Should coneflowers be deadheaded?

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 are coneflowers multiplied?

Coneflowers rarely yield more than 20–30 undesirable seedlings per plant in my experience. Additionally, this only happens in disturbed or open soil, or in mulch. Because the roots are only a few inches long, it only takes approximately five minutes to remove the seedlings (25 mm). Therefore, I don’t think the spreading is a problem.

The immature, delicate seedlings can also be readily potted up to continue growing and finally placed somewhere more appealing. But you can move on to the following stage if you don’t want any stray coneflower seedlings. Coneflowers can be kept from self-seeding with a very easy approach.

Deadhead Coneflowers to prevent spreading

It is quite simple to stop the proliferation of coneflowers. Once the coneflowers’ blooms have faded, just deadhead them. You must continue until they cease blossoming.

Using pruning shears or scissors, cut the stem where it joins the two leaves, starting at the spent bloom. Just above these two leaves, trim the stem. By doing this, you will stop seeds from developing and new plants from sprouting the next Spring.

Physical Description

Coneflowers grow numerous daisy-like flowers on stems that are up to 4′ tall. When fully grown, the plant will have a diameter and spacing of 2′ to 3′. In the majority of kinds, the leaves are broad, lance-shaped, serrated, and several inches wide. The majority of coneflower species have taproots and are difficult to transplant. Echinacea purpurea, a common Purple Coneflower, has fibrous roots and is simple to divide.

Coneflowers are frequently planted in well-kept flower beds, border gardens, backyard meadows, and micro-prairies. These plants are typically well-behaved and, when positioned properly, look really stunning. Coneflowers are an essential component of the environment because they attract a variety of pollinators, including bees, butterflies, and birds that eat the seeds they produce.

When can cornflowers be transplanted?

When starting seedlings indoors, move them to their final garden bed before they reach a height of 4 inches. Only transplant when the threat of frost has passed. For maximum results, cornflowers need moist but well-drained soil and direct sunlight. Always replant flowers that were grown in pots at the same depth in the bed where they were originally planted. While perennials require at least 2 feet between plants, annual species only need a 6- to 12-inch gap. Cornflowers need space to spread out since they develop numerous stems, each of which might bloom.

How far apart should coneflowers be planted?

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.)

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.
  • 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.

Learn more about the advantages of planting coneflowers by watching our video:

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.
