I bought some flower seeds and they won't come up?

I bought zinnias, wildflower mixes, snapdragons, and some others that are supposed to spread. I planted them according to the directions on the back of the seed packets and nothing has come up yet. Regular watering, tilled soil, etc. The soil was great. The packets said 7-10 days germination. It's been about 14 now. Shouldn't I be seeing something already?

Maybe you planted them to deep?
Reply:Did you know that certain seeds like the temperature of the ground a certain temperature before they start growing if you live in a place that is still having some cooler weather you might want to give the ground a little more time for instance for pumpkins to start growing the temperature of the ground needs to be 70 degrees before the pumpkin seeds really start to grow so since it is spring and you did not say where you are at Id give them a little more time.
Reply:depends on soil conditions and temperatures too. Also, look on your seed packets if you still have them, what year where the seeds packed for? If it's a year other than 08 sometimes they lose the germination success rate. Give it a few more days and see if you don't start seeing something!
Reply:you could try starting seeds in your home first with jiffy starter packs, they are little pellets that you add water and seeds to, when they start to grow, you can transplant them outdoors.
