How to Grow Coneflowers
- Choose the right coneflower varieties for your tastes and your garden.
- Plant coneflowers in full sun in the spring or early fall.
- Prepare in-ground soil by adding Miracle-Gro® Garden Soil for Flowers.
- Water plants thoroughly at the time of planting and regularly throughout the season.
How do you plant coneflowers?
Choosing and Preparing a Planting Site
- Coneflowers prefer well-drained soil and full sun for best bloom.
- They may reach between 2 and 4 feet in height, depending on variety.
- Coneflowers are very tolerant of poor soil conditions, but they perform best in soil that’s rich so mix in organic matter if needed.
How deep do you plant cone flowers?
How to plant: To plant Echinacea seeds, loosen the soil to a depth of 12 inches. Add compost to the top 2-4 inches of soil. Seeds take approximately 3 to 4 weeks to germinate, and you should see true leaves at about 12 weeks.
Do coneflowers spread?
Spacing: Coneflowers are clumping plants. One plant will tend to get larger, but it will not spread and overtake the garden via roots or rhizomes. Because Echinacea establish deep taproots, you need to plant them where you want them. They do not like to be moved once established.
Are cone flowers easy to grow?
Coneflower plants are heat- and drought-resistant, which makes them easy to grow even for beginners. “Coneflowers do best in full sun, and bloom within roughly 60-90 days,” says Sears. “Most coneflowers will do best in USDA zones three to nine.” Just make sure you plant them somewhere they’ll see plenty of light.
When should I plant coneflowers?
The best time to plant coneflowers is in the spring, when all danger of frost has passed. You can also plant in early fall. Just be sure your new plants have at least 6 weeks to establish roots before the first expected frost or they might not come back in the spring.
Do coneflowers bloom the first year?
Flowers reliably bloom the first year from seed if sown early (see Summer Flowers for Color). Pinch off spent flowers on a regular basis — or use them as cuttings in flower arrangements — to extend the blooming period.
How long do cone flowers bloom?
Coneflowers bloom for about two months, attracting birds and butterflies to the garden. After the flowers fade, the domed seedheads stand tall through the winter.
What grows well with coneflowers?

Should coneflowers be deadheaded?
In the beginning of the bloom season, to encourage more flowering, deadhead coneflowers regularly by cutting off the faded blooms before they produce seeds. Later in the season, when the plant begins to produce fewer blooms, you can just let them be. Let the plants stand during the winter to provide food for birds.
Do cone flowers reseed themselves?
In fall, break seed heads apart, sprinkling seeds where you want more coneflowers to grow. Or let coneflowers self-seed on their own. Most coneflowers grown from seed won’t flower until their second growing season.
Can you separate coneflowers?
Divide your coneflowers in the spring or late fall. Planting in the early spring is ideal because the plants have yet to bloom, while fall also works because the blossoms die down. Conducting division during these months is the least invasive and will minimize damage done to the plant.
How do you plant coneflower seeds outside?
Sowing Directly in the Garden:
- Direct sow in late summer at least 12 weeks before the ground freezes.
- Remove weeds and work organic matter into the top 6-8 inches of soil; then level and smooth.
- Sow seeds evenly and cover with 1/4 inches of fine soil.
- Firm the soil lightly and keep it evenly moist.
Do coneflowers bloom all summer?
That being said, deadheading is the primary maintenance for coneflowers. They are prolific bloomers, and deadheading (removing the dead flowers from living plants) will keep them in bloom all summer. Flowers start blooming from the top of the stem, and each flower remains in bloom for several weeks.
Why do my coneflowers fall over?
Coneflowers do not grow well in heavy, clay soils that retain moisture. Too much moisture in clay soils may cause flower buds to wilt over before they start to bloom. Alternately, lack of water, particularly in full sun, may also cause buds to droop, though they tend to perk back up in the evenings.
