Growing Tips
- 1Plant coneflowers in a sunny spot, as they thrive with at least 6 hours of direct sunlight each day.
- 2Use well-draining soil and water them moderately, allowing the soil to dry out between waterings to prevent root rot.
- 3Space plants about 1 to 3 feet apart to ensure good air circulation, which helps prevent diseases and pests.

How to Harvest
- 1Harvest coneflowers when the petals have fully opened and the central cone is firm.
- 2Use sharp, clean scissors or pruners to cut the stem about 12-18 inches below the flower head, making the cut at a slight angle.
- 3To avoid damaging the plant, leave some flowers on the plant to allow for reseeding and continued growth.
Step 5
Saving Seeds
How to Save Seeds
Saving seeds from your Coneflower plant is easy and rewarding! Once the flowers have faded and the seed heads turn brown and dry, simply snip them off and gently break them apart to collect the seeds inside. Let the seeds air dry for a few days, then store them in a labeled envelope or paper bag in a cool, dry place until you’re ready to plant. You’ve got this—saving seeds is a simple way to keep your garden growing year after year!
