The brightly coloured petals and large centre 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 -1.11 degrees Celsius. Whether grown in beds or pots, the plants require a regular fertilisation schedule to ensure best bloom and continued plant health.

  1. 1

    Fertilise garden gerbera daisies in spring after planting or once perennial plants begin showing new growth. Apply slow-release, low-phosphorus fertiliser, such as 15-5-15, at the rate recommended on the package for the size of your bed.

  2. 2

    Water the plants immediately after fertilising, rinsing the foliage with the water. The leaves are easily burnt by contact with fertiliser.

  3. 3

    Fertilise a second time two months after the first application. Apply a third application two months after the second application.

  4. 4

    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.

Tips and warnings

  • Fertilise potted gerbera daisies with a slow-release fertiliser as you would garden plants. Alternatively, apply a soluble fertiliser once monthly when the plants are actively growing.
