Things You'll Need
Shredded leaves and bark
Balanced fertilizer (10-10-10)
The winter care technique for gerbera daisies depends on where they are grown. These showy blossoms will not tolerate freezing cold winter temperatures. In the winter, the roots have to be kept adequately warm. In USDA zones 8 through 11, gerbera daisies can be overwintered outdoors in the ground. In colder regions, you must grow them in containers and move them indoors for the winter.
USDA Zones 7 and Lower
Move potted gerbera daisies indoors before the first frost of the season.
Place the potted gerberas in an indoor area with temperatures between 40 and 45 degrees Fahrenheit. An area that receives partial sunshine would be ideal. The potting soil must dry out slightly before you water the plant again.
Mix the fertilizer with water according to package recommendations to fertilize the daisies. Fertilize the daisies once every other month during autumn and winter.
Remove the plant from its existing container in the spring after temperatures rise above freezing. Fill the container with fresh potting soil and replant the gerbera daisies in the container. Move the gerbera daisies back outside again when the temperatures climb above 45 degrees Fahrenheit.
USDA Zones 8 through 11
Cover the growing area with at least 4 inches of shredded leaves or bark to insulate the roots from possible freezing temperatures.
Pound 3-foot stakes at least 6 inches into the soil surrounding the daisies. Stretch burlap around the outsides of the stakes and wrap twine around the burlap to hold it in place. This will create a windbreak around the daisies.
Water the gerberas once or twice each month. Pour only enough water over the roots to keep them from completely drying out.
Mix the fertilizer with water according to package recommendations. Fertilize the daisies once every other month during autumn and winter, and once a month in the spring and summer.
