Georgia falls into the USDA hardiness zones 6 through 8 with a costal climate marked by warm summers and mild winters. This means that large portions of the state never experience winter temperatures below 0 degrees F. Winter flowering annuals will thrive in Georgia if planted in fall, and will bring color all winter long. Many winter flowering annuals are hearty down to -20 degrees, and will thrive in Georgia's mild climate.
Break up the soil for your winter flowering bed by inserting a spade into the ground to a depth of 8 inches. Loosen the soil by working the spade back and forth.
Remove any rocks, sticks, debris and remnants of old plants and roots from the planting bed with a rake.
Spread peat moss over the bed in a 4-inch layer and then mix in with the soil using the rake.
Dig holes that are twice as deep as the seed's diameter at its widest point. Plant seeds and cover with soil.
Water the flowers until the roots become established. The soil should remain as wet as a wrung-out sponge. Check the soil once weekly in your garden. Winter gardens need water less frequently than summer gardens.
