- 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.
How soon should I prune my coneflowers?
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.
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 shorter?
In the early summer, use pruning shears to trim the coneflowers to half their length. The plant will grow back more compactly and stockily, but this is optional and may result in late blooming.
How can you ensure that coneflowers bloom all summer long?
That being stated, the main care for coneflowers is deadheading. Since they bloom frequently, you can prolong the blooming season by deadheading (removing the spent flowers from living plants). Each flower blooms at the top of the stalk and continues to bloom for a few weeks.
