When To Plant Echinacea Plants

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.

When should Echinacea be planted?

In its first year, echinacea doesn’t always flower properly. If you want to give yourself the best chance of a good display the next year, plant out in the early fall (September or October).

Echinacea will germinate in approximately three to four weeks and generate leaves in three months if you plant them in the early spring (after the last frost) as part of your spring gardening tasks, but it can take up to two years for them to really produce blossoms.

Is echinacea a perennial plant?

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.

Can I plant echinacea right now?

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.

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.

Are coneflowers contagious?

I’ve cultivated countless coneflowers of various types over the years. I now fully understand how coneflowers proliferate and how to handle them. So let me share what I’ve discovered with you.

Coneflowers reproduce through self-seeding and developing a deeper root system. Coneflowers do not, however, spread their roots and take over gardens (rhizomes). Each Spring, a coneflower plant may produce several seedlings, and its root mass may enlarge by one to two diameters. However, it won’t produce runner roots.

So, if you’re interested in learning how far a coneflower will spread, continue reading and check out the images.

Are dogs poisoned by echinacea?

Coneflowers are a lovely, low-maintenance addition to a sunny garden, and you may have even heard Echinacea used in herbal medicines, but does that indicate that it is safe for kids, animals, and other creatures to eat?

Echinacea species are not generally thought to be poisonous. A UC Davis study found that the plant’s entire composition is regarded as safe for consumption.

However, consuming enough of any new plant material could upset your stomach or digestive system, so speak to your doctor or veterinarian right away if you are worried about your child, dog, cat, or other animal.

Is echinacea shade-tolerant?

Moderate/Watering: Full sun is ideal for flowering, though plants can take some light shade. Once established, these plants are highly drought-tolerant because to their deep taproots.

Echinacea purpurea may grow in a variety of soil types, although it likes sandy, well-drained loam with a pH range of 6.0 to 7.0. No additional fertilizer will be required if a few inches of organic matter, such as compost or well-rotted manure, is applied around the plants in the early spring.

Echinacea is rarely plagued by pests or illnesses, and none are severe enough to call for protective measures. Plants do draw beneficial insects, particularly soldier beetles that resemble fireflies and eat caterpillars and aphids.

Companion Plants: Dwarf Goldenrods (Solidago) and Salvia are excellent companions, as are perennial Geraniums, dwarf types of Catmint (Nepeta), and perennial Geraniums. Shorter perennials can conceal occasional legginess. Perovskia, Phlox, Sedum, Veronica, and Monarda are companion plants that grow taller.

Reflowering: Even without deadheading, echinacea has a lengthy bloom season, but this method will lead to more blooms. Early in the summer, plants can be pruned by half for a later blooming period but a more compact form. There are few sights more pleasant than watching the small, golden birds wave about as they pick up the seeds, so leave some seed heads to serve as food for goldfinches.

Plant transplantation and dividing: Because of the taproot, elder plants might be challenging to transplant. However, it is possible if you dig deeply and leave a substantial amount of soil around the roots.

Calendar of Care

Late Spring: Only if the climate is exceptionally dry or if the Coneflowers have just been planted, add extra water.

Summer: You can deadhead if you’d like, but remember to leave some seeds for the goldfinches. In August, keep an eye out for beneficial army beetles and avoid harming them. In June, plants can be pruned back by half for later-flowering, more compact growth.

Fall: In cooler climates, a light mulch is good. Because the seed heads feed hungry birds and accumulate snow into gorgeous tiny puffs, plants may survive the winter.

How is echinacea prepared for winter?

The ideal course of action would seem to be to prune all of your perennials in the fall. I see why you would want to trim down the perennials and get ready for the upcoming Christmas season—you have lovely fall weather, you’re already raking leaves, etc. Unfortunately, our desires and the needs of our plants are not always the same. Here are some common queries about perennial winterization answered.

Depending on what you have planted in your garden, the process of effectively winterizing your perennials can frequently take place from late October into the first few weeks of spring. The most important thing when cutting perennials for the fall is to take your time.

A plant’s leaves are what give it life, so they should never be entirely clipped until after several hard frosts. It is possible for the plant to absorb the additional energy it requires by letting it naturally wither away. The plant moves its energy from the dying foliage to the roots, where it will be stored for the winter and used to grow a new, attractive plant in the spring. By pruning a perennial too soon in the fall, you run the risk of weakening it and having it perform poorly the next year.

The perennial variety will determine when to prune, but there are primarily 3 categories to consider:

  • After the deadly frost, thoroughly prune the tree.
  • In the spring or fall, prune to the base of the leaves.
  • Never prune in the fall (prune or clean up in spring)

1. After the fall killing frost, totally prune the tree. Although pretty self-explanatory, be aware that this process could happen at any time between mid-October and December.

  • When the foliage turns black, cut the anemone (Anemone x hybrid) to the ground.
  • When the beebalm (Monarda) dies back, cut it to the ground. Occasionally, if powdery mildew is a serious infestation, this may need to be reduced early.
  • Nepeta catmint should be cut down when the foliage turns brown.
  • Cut down Cranesbill (Geranium) when the foliage turns brown.
  • Hemerocallis daylily, cut to the ground as the leaf turns brown.
  • Cut Hosta (Hosta) to the ground once the leaf has withered.
  • Cut the iris (Iris sibirica) to the ground when the leaf withers or leave it for winter interest and trim it back in the spring before the new growth appears.
  • When the foliage dies down, cut the peony (Paeonia) to the ground.
  • Cut to the ground Sedum (Sedum) as the foliage dies back, or leave for winter interest and trim in the middle of winter or in the first few weeks of spring before new growth starts.
  • When the foliage on tall Phlox (Phlox paniculata) dies back, cut it back to the ground.
  • When the foliage on Threadleaf Coreopsis (Coreopsis verticillata) dies back, cut it back to the ground.

2. Completely prune in the spring or fall to the base foliage. A structure’s base is referred to as its basal. In its simplest form, basal foliage is fresh foliage that emerges at a plant’s base.

  • Susan the Black-Eyed (Rudbeckia) For the benefit of wildlife, leave the seed heads up in the winter. In the spring, just wipe off the remaining leaves and cut the stems back to the basal foliage.
  • Campanula (Bellflower): In the fall, prune back to the basal foliage.
  • Coneflower (Echinacea)
  • For the benefit of wildlife, leave the seed heads up in the winter. In the spring, just wipe off the remaining leaves and cut the stems back to the basal foliage.
  • Penstemon (Penstemon digitalis) should be pruned in the fall to the basal foliage.
  • Trim the stems of the Shasta Daisy (Leucanthemum) to the basal foliage in the fall, and then in the spring, only remove any leftover foliage.
  • In the fall, cut back yarrow (Achillea) to the basal foliage.

Avoid pruning in the fall (prune or clean up in spring). Some perennials simply benefit from having more leaf on top in the fall to protect the plant’s crown, but evergreen and woody perennials should never be cut back.

  • Aster (Aster) In the spring, before the emergence of new leaf, totally prune.
  • Before the new leaf emerges in the spring, fully prune the asters.
  • Monarch Butterfly (Asclepias tuberosa)
  • It’s not necessary to wait until spring to cut this back, but because it blooms later than most other perennials, it’s usually simpler to leave it alone so that it can freely reproduce. In order to avoid mistaking the new seedlings for weeds come spring, you’ll need to know where it was in your garden.
  • Although it is not required to wait until spring, Cardinal Flower (Lobelia cardinalis) benefits from the additional leaves on top to help protect the plant’s crown.
  • Camembert Pinks (Dianthus gratianopolitanus)
  • Simply remove the dried flower stalks and any untidy foliage in the spring after they bloom because these have evergreen foliage.
  • Coralbells (Heuchera) have evergreen foliage, so in the fall, cut the flower stems to the base foliage, and in the spring, tidy up the foliage as needed.
  • Invading Phlox (Phlox stolonifera)
  • Simply clean the foliage once the spring blooms have passed since these have evergreen foliage.
  • False indigo (Baptisia australis): Either leave the foliage for the seed heads, or cut it back completely as new growth starts to emerge in the spring by cutting back by a third in the fall.
  • Lavender (Lavandula)
  • Since lavender is a woody perennial, they only need a small amount of shaping trimming in the late fall or early spring. Avoid forcing growth before a frost by not pruning back too early; you want the growth to be hardened off so the frost won’t destroy it.
  • Before the chrysanthemum’s new foliage emerges in the spring, fully prune the plant. Mums benefit from having more leaves on top throughout the winter to shield the plant’s crown.
  • Rogue Sage (Perovskia)
  • Since Russian sage is a woody perennial, only a moderate pruning to shape them in the early spring is beneficial.

There are several exclusions to the guidelines, as there usually are with gardening:

  • Pruning down in the fall, Bearded Iris Although the leaves will still be green, they must be removed since the iris borer’s larvae are found there.
  • Decorative Grasses
  • When ornamental grasses are left uncut after dying back, they produce stunning winter interest in the garden. If you must trim back in the fall, be sure to wait until they have fully died back. Make sure to prune in the early spring before new growth appears if you do so. For information on how to prune the various grass varieties, click here.
  • RosesIf it has to be shaped, leave the rest and only chop down a third. Any severe pruning should be postponed until early spring, right before new growth emerges.

When pruning and cleaning up your garden in the winter, remember to always practice excellent garden sanitation. To try to contain and control the disease, make sure to remove all foliage from the garden and the ground if you know a plant is sick. In order to avoid unintentionally spreading any diseases, you should also routinely clean your pruners with rubbing alcohol or a bleach and water solution.

Although perennials need patience, the reward is definitely worth the effort!
