You can just poke the seeds into the ground and they'll come up easily enough.
The big question is what growing conditions you have? I know the seeds in my birds' mix (millet, sunflower, and safflower) all do best with full sun and decent drainage. My yard has too much shade for them to thrive, but I'm going to take a crack at safflower this year anyway, because I never learn my lesson, lol.
