How to grow & propagate coreopsis (tickseed)
Everything I've worked out about starting this one, keeping it alive through a Texas year, and turning one plant into many — free.
How to propagate coreopsis (tickseed)
The daisy family is a seed family — those flower heads are seed factories, and most members come up fast and willing from direct sowing. The perennial members (coneflower, black-eyed Susan, the native sunflowers) also clump up over a few years and can be lifted and split in fall or early spring to make free plants and keep the center from dying out.
Growing coreopsis (tickseed) in Texas
Give it full sun and tolerant soil. Match the spot to the plant and most of the battle is already won.
Time your planting to our long warm season and watch the frost dates at both ends; the live weather tool on this site is built for exactly that.
Once it's rooted in, this is a low-water plant — overwatering does more harm than drought here. Water deeply to establish, then back off and let it prove how tough it is.
Harvesting
Figure on roughly blooms spring-summer before you're harvesting.
Making more for free
If you want more, let your healthiest plants mature fully and collect the seed once it's dry on the plant — then store it somewhere cool, dark, and dry until next season.
