Seeds of annual flowers fluctuate in their hardiness and talent to germinate beneath sure soil temperatures. Hardy annuals will be direct-seeded in early spring. Do not seed tender annuals till the soil has warmed to 60° F. As soon as the planting mattress has been ready, make a shallow furrow for planting the seed.
