Should purple coneflowers be cut back?
Cutting back or pruning coneflowers is an important maintenance task because it rejuvenates the plant. It encourages new growth, increased blooms and keeps the plant from looking overgrown or untidy. Pruning is a necessary task for all gardeners because it keeps their plants healthy and gardens beautiful.
Where do coneflowers grow best?
Coneflowers prefer well-drained soil and full sun for best bloom. Choose a location where the coneflowers won’t get shaded out nor shade out others. They may reach between 2 and 4 feet in height, depending on variety.
Do I need to deadhead coneflowers?
Most coneflowers produce several flowers per stem and will rebloom without any deadheading. Oftentimes, new blooms will appear at leaf nodes before the top flower finishes wilting. In late summer to fall, stop deadheading spent blooms so that birds can eat the seed through the fall and winter.
How do you keep coneflowers blooming all summer?
Cut the coneflowers down to one-half of their length with pruning shears in the early summer. This is optional and can cause late blooming, but the plant will grow back more compact and stocky. Deadhead coneflowers throughout the summer and early fall when the flowers wither or dry up.
Can 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. If a plant is estimated to grow to 18 inches wide, leave 18 inches between plants. Because Echinacea establish deep taproots, you need to plant them where you want them.
How tall do coneflowers get?

What should I do with my purple coneflower plant?
Although coneflowers thrive best in a soil high in organic matter, too much supplemental fertilizer can cause them to become leggy. Adding compost each spring usually gives them the nutrition they need for healthy foliage and blooms. Pruning purple coneflower is helpful, but not imperative.
Are there any problems with my coneflower plant?
For the most part, coneflowers have very few problems. As long as the plants are given plenty of room for good air circulation, they should not be bothered by fungal diseases. If you see mildew or spots on the leaves, simply cut them back and let them fill in on their own.
Can a aster leafhopper survive in a perennial?
Don’t—the pathogen can survive in perennial plants from one season to the next, and infected perennials can transmit aster yellows to other plants for many years. All it takes is an aster leafhopper feeding on that plant. For that reason, you should remove any perennials—landscape plants as well as weeds—from your garden.
