Gerbera daisies (Gerbera jamesonii) were discovered in the 1800s by a gold miner in South Africa, according to Auburn University. Gardeners have fallen in love with the plants thanks to the daisy's relatively low-maintenance nature and its bright blossoms. If your gerbera daisy isn't blossoming or is only producing a limited number of flowers, give it the care and management it needs for optimal flower growth.
Provide your gerbera daisies with lots of sunshine. The plants thrive best in a minimum of six hours of sunlight daily. Insufficient sun can cause poor blossom production and thin, pale foliage.
Test the soil around your gerbera daisies with a soil pH testing kit. Gerbera daisies grow best and bloom the most in a soil pH of 5.5 to 6.2, according to the Alabama Cooperative Extension. Raise or lower the pH of the soil with various types of limes and phosphates, respectively. Consult your local cooperative extension system office to find what pH amendments are commonly used in your area.
Fertilize the daisy plants once a month during the summer growing season. Insufficient nutrition will cause little to no flower production as the plant tries to save energy. Auburn University recommends using any low-ammonium fertilizer like a 15-15-18 or 15-16-17 product. Spread the fertilizer around the plant's roots at the rate listed on its label, since potency varies widely by product and brand.
Water the gerbera daisies once every two to three days. Use enough water to moisten the soil to a depth of 6 inches, then wait to water until the top 2 inches of dirt feel dry to the touch. This helps reduce the chances of the plant contracting a fungal disease and also improves the health of the flower stems, according to the Alabama Cooperative Extension.
Deadhead the gerbera daisy as soon as its flowers wilt, according to North Dakota State University. Snip off the flower stem as close to the base of the plant as possible. This encourages the plant to produce more blossoms.
