Care for Coneflowers

By Kathryn Hatter ; Updated September 21, 2017

Coneflowers are native to North America and grow prolifically in both landscape areas and naturalized prairies. Coneflowers come in a variety of different colors, with purple being the best known of the coneflowers. Gardeners who seek to attract hummingbirds and butterflies to a growing area often add coneflowers to their flower gardens. Coneflowers are easy to grow and spread quickly to establish themselves.

Plant coneflower seeds in the spring after the last spring frost. Choose a sunny growing location and spread the seeds with 12 inches between each seed. Cover the seeds with ΒΌ inch of soil.

Water the planting area generously after planting and keep the soil moist during germination. Watch for the seeds to germinate between one and three weeks after planting. Provide enough water to fully moisten the soil if the weather is dry; otherwise, the coneflowers do not need supplemental irrigation.

Fertilize the coneflower plants approximately one month after planting and again 6 weeks later. Mix the fertilizer with water according to package recommendations and pour the fertilizer onto the soil around the coneflower plants.

Stake tall varieties of coneflowers if they need support to stay erect. Push the stakes into the soil 2 to 3 inches away from the stems and tie the stems to the stakes.

Control the spread of coneflowers by clipping the spent flowers from the stems immediately after they fade. If you wish to allow the coneflowers to spread in a growing area, leave the spent flowers on the plants until autumn. This will enable the seeds to drop to the soil and the seeds will self-sow for new coneflowers during the next growing season.


Things You Will Need

  • Coneflower seeds
  • Trowel
  • All-purpose fertilizer (water-soluble)
  • Stakes
  • Twine
  • Pruning shears


  • Instead of spacing the coneflower seeds carefully, spread them evenly over a growing area for a wildflower effect.
  • Coneflowers are hardy to USDA zones 3 through 9.
  • Coneflowers do not need any special winter protection.


  • Avoid getting fertilizer on foliage because it may burn the tender leaves.
  • Coneflower roots may decay if the soil does not drain adequately. Do not allow coneflowers to sit in soggy soil.
