  •  Seedlings emerge in 15-30 days
  •  When seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow. Incandescent bulbs are not recommended, because they will get too hot. 
  •  If growing coreopsis in small cells, transplant the seedlings to 3 or 4 inch pots when they have at least 2 pairs of true leaves before transplanting to the garden so they have enough room to develop strong roots.
  •  "Harden Off "Coreopsis seedlings before transplanting outdoors. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning.  


Sowing Coreopsis Directly Outdoors:


  •  Plant Coreopsis in full sun with well-drained soil after danger of frost has passed. In frost free areas sow from fall to early spring.
  •  Remove weeds and work organic matter into the top 6-8 inches of soil; then level and smooth.
  •  Sow evenly and thinly cover with ½ inch of fine soil.
  •  Firm the soil lightly and keep it evenly moist.
  •  Seedlings will emerge in 15-30 days.
  •  Thin to 18 inches apart when seedlings are 2 inches tall.
