how to deadhead coreopsis grandiflora-tickseed
Do I simply pull off the head of the flower (like a marigold), or do I remove the entire stem (like a geranium)? Also, where can I purchase various coreopsis seeds? Thank-you!

I like to trim mine down to the next leaf structures.
I use a small sharp garden scissors and it makes a nice clean cut.
