Coreopsis Planting and Care Guide

Quick Facts About Coreopsis

Plants in the Coreopsis genus are commonly called Tickseed due to the seeds resembling little ticks. There are some species that are annuals and some that are perennials, and both grow readily from seeds. Once established, Coreopsis is fairly heat and drought tolerant. The flowers are excellent for cutting and last for most or all of the summer, attracting butterflies and other beneficial insects. Coreopsis is great for flower beds and borders as well as naturalized meadows and prairies, and the plants are usually deer resistant.

Planting Time

Coreopsis seeds can be started indoors 6 - 8 weeks prior to the end of frost season. Or, sow the flower seeds directly outside once frost danger has passed.

Planting Location

Coreopsis prefers to live in full sun and tolerates partial shade. The plants are not picky about soils, but a neutral pH and a well-draining soil is best.

How to Plant Coreopsis

  • Start the Coreopsis seeds in starter trays
  • Press the seeds into the soil but do not cover
  • Keep the seed continually moist and warm for germination
  • Keep tray in a bright sunny window for growing
  • Once the seedling is several inches in height, harden off 7 - 10 days
  • Transplant outside
  • Or, weed and work the soil to a depth of 6 inches or so
  • Add compost to improve soil
  • Rake the soil smooth and scatter the Coreopsis seeds
  • Press the flower seeds into the soil but do not cover them
  • Keep the area continually moist for germination
  • Thin to strongest plant 12 inches apart

Care And Maintenance

  • Irrigate regularly to establish Coreopsis plants
  • Once established, Coreopsis plants are fairly drought tolerant, but the bloom production is higher with consistent irrigation
  • Mulch around the base to suppress weeds and help maintain moisture
  • Cut the plant back by 1/3 in mid-summer to promote new growth and new blooming
  • Once die back starts in fall, trim back and remove dead material
