Watering

Water Purple Coneflower deeply and infrequently to ensure its roots are reaching deep into the soil. You should water the soil to a depth of 3-4 inches and do it about every 7-10 days, or whenever the top few inches of soil is dry. Place your finger into the soil up to the second knuckle for an accurate assessment of the moisture levels. Make sure it does not remain soggy or overly wet.

Light

Purple coneflowers (Echinacea purpurea 'Kim's Knee High') need full-sun or at least 6 to 8 hours of sunlight per day.
