The brightly colored petals and large center eyes make gerbera daisies a bold addition to planters or garden beds. The flowers are grown primarily as potted plants, but they also survive in a flower garden. Gerbera daisies are perennials but are grown as outdoor annuals in areas that experience temperatures below 30 degrees Fahrenheit. Whether grown in beds or pots, the plants require a regular fertilization schedule to ensure best bloom and continued plant health.
Things You'll Need
- Slow-release fertilizer
- Iron foliar spray
Fertilize garden gerbera daisies in spring after planting or once perennial plants begin showing new growth. Apply slow-release, low-phosphorus fertilizer, such as 15-5-15, at the rate recommended on the package for the size of your bed.
Water the plants immediately after fertilizing, rinsing the foliage with the water. The leaves are easily burned by contact with fertilizer.
Fertilize a second time two months after the first application. Apply a third application two months after the second application.
Spray the daisies with an iron foliar spray in midsummer if the foliage begins to yellow. Gerbera daisies are prone to iron deficiencies. Follow the instructions on the spray label for proper application method and amount.
