Gerber (Gerbera) daisies are big and showy, with brightly colored flowers. These annuals are desirable for their wide range of neon colors---and show spectacular results with only basic care, according to North Dakota State University. Gerber daisies are usually sold as young potted plants rather than by seed, as the seeds are very delicate. Grow them in a pot, or plant them in the garden and enjoy the rainbow of colors they provide all summer long.
Plant your Gerber daisy in well-draining, sandy soil rich in organic matter. Add peat moss to improve drainage and nutrients, if the potting soil does not already contain peat moss.
Place your Gerber daisy in a sunny location, but take care not to overheat the plant, or it can wilt, according to information published by North Dakota State University. Warmer climates with hot summers should place the daisies where they will receive dappled shade in the afternoon, if grown outdoors.
Keep the soil evenly moist while the flowers are blooming but not soggy, or the plant may develop root rot, a fungal disease that attacks the roots of the plant. Let the soil dry out a bit between waterings after the plant has finished blooming.
Fertilize your daisies regularly. Gebera plants are heavy feeders, according to the University of Florida. Apply a slow-release, iron-rich fertilizer at the start, middle and end of the growing season (late spring through summer). Water before and after applying the fertilizer.
Remove the faded flowers and stems to keep the plant looking attractive. Watch for insect pests such as spider mites and spray with insecticidal soap to treat any infestations.
