When to Plant Coreopsis Seeds
To start indoors you can plant Coreopsis indoors 6-8 weeks before you transplant it outdoors after the last killing frost. You can also directly sow your seeds into the ground after the last frost when the soil has become workable.
Where to Plant Coreopsis Seeds
Whether you are transplanting or directly sowing, choose a well lit area with well-draining soil.
How to Plant Coreopsis Seeds
Coreopsis seeds require light to germinate, so be careful not to cover them when planting. Learn more about germination light requirements here.
Once all weeds are removed, plant your Coreopsis seeds 1/2″” deep and lightly cover them with soil or lightly press them in. These seeds need sunlight to germinate so make sure you don’t fully cover them.
If transplanting, dig a hole big enough to engulf the root ball and surround with fertile soil. The top of the root ball should be level with the ground. Routinely water plants but be careful not to overwater.
How to Care for Coreopsis
When blooms begin to fade, deadhead them to encourage new growth. Thin out plants when they become 2″ tall.
