I was over zealous a week ago when the weather was nice and warm and planted my Zinias. Since then we have had some really cold weather (-3 with the wind chill) Can anyone tell me if there is any hope of my seeds germinating? It is a very large flower bed in my front yard so I grow from seed. Not even 1 seed has sprouted yet. When I have started them in the house they only take 2 - 3 days.

Thanks
