The scientific name of these bright blooming flowers is Gerbera jamesonii, but many gardeners prefer Gerber daisy. The vibrant colors of Gerber daisies make them a favorite among gardeners. Because Gerber daisies are sensitive to cold temperatures, only gardeners living in regions where the temperature will not fall below 10 degrees Fahrenheit can successfully grow Gerber daisies as a perennial flower unless they take the daisies indoors. Winterize Gerber daisies to keep these garden beauties growing energetically for many years.
Winterizing Perennial Gerber Daisies
Cut back the Gerber daisies growing in the soil to just above the soil level before the first autumn frost. Use the pruning shears to cut the stalks off approximately 1 inch above the soil level.
Cover the Gerber daisies with between 3 and 4 inches of shredded mulch, making sure you cover the entire planting area evenly with the mulch.
Remove the mulch the following spring when the temperatures moderate and all threat of spring frosts pass.
Winterizing Annual Gerber Daisies
Cut back the Gerber daisies growing in containers to just above the level of the potting soil with the pruning shears. If you have Gerber daisies growing in the ground, they will not survive the winter if temperatures fall below 10 degrees Fahrenheit. Therefore, gardeners living in these colder regions must grow Gerbers as annual flowers when planting in the soil (replacing them each spring with new flowers) or grow them in containers.
Move the Gerbers in containers from their outside growing location to a protected location where temperatures will stay around 40 degrees Fahrenheit.
Provide water for the Gerber daisies once or twice each month to prevent them from completely drying out.
Move the Gerbers outside when temperatures moderate and all threat of spring frosts pass.
