Gerbera Daisy

Plant gerbera daisies in spring after the last frost in rich, well-drained soil in full sun. The critical planting detail is to set the crown slightly above the soil surface, as burying the crown leads to crown rot, the most common cause of failure. Space twelve to fifteen inches apart and ensure excellent air circulation around the plants.

Water at the base rather than overhead, keeping the crown and foliage as dry as possible. Gerbera daisies need consistent moisture during active growth but are extremely sensitive to crown rot in wet conditions. Feed every two to three weeks with a balanced liquid fertilizer during the growing season. In hot climates, light afternoon shade prevents flower color from bleaching.

Remove spent flower stems by pulling them gently from the base. Deadheading encourages continuous blooming from late spring through autumn. In zones 8 and above, gerberas are perennial and will return each year if drainage is excellent. In colder zones, grow as annuals or bring container-grown plants indoors before frost. Gerberas are also outstanding greenhouse crops for year-round cut flower production.

The gerbera daisy (Gerbera jamesonii) originates from the grasslands and rocky slopes of South Africa's Mpumalanga and Limpopo provinces, formerly known as the Transvaal. The species was first collected near the mining town of Barberton in the 1880s by Robert Jameson, a Scottish-born gold prospector and amateur naturalist, which gave the plant its botanical epithet 'jamesonii.' It was formally described and classified by Sir Joseph Dalton Hooker at the Royal Botanic Gardens, Kew, in 1889. The wild species bears modest orange-red flowers on short stems, a far cry from the spectacular cultivars grown today. The transformation of the gerbera from a regional wildflower into a global horticultural commodity began in the early 1900s when Richard Irwin Lynch at the Cambridge Botanic Garden in England crossed Gerbera jamesonii with the closely related Gerbera viridifolia, producing hybrids with larger flowers and a wider color range. These early hybrids attracted the attention of Dutch and Danish flower breeders, who recognized the commercial potential of the gerbera as a cut flower. By the mid-twentieth century, intensive breeding programs in the Netherlands had produced thousands of cultivars with improved stem length, vase life, disease resistance, and an extraordinary spectrum of colors. The introduction of tissue culture propagation in the 1970s revolutionized gerbera production, allowing growers to mass-produce genetically identical plants with consistent flower quality. Today, the Netherlands, Colombia, and Kenya are the leading producers of gerbera cut flowers. The plant has become deeply embedded in the global floriculture industry, consistently ranking among the top five cut flowers sold worldwide, with annual production valued at over one billion dollars.

Gerbera daisies require rich, well-drained soil with a pH of 5.5 to 6.5. They prefer slightly acidic conditions and may develop iron chlorosis in alkaline soils. Amend with compost and ensure excellent drainage by adding perlite or coarse sand to heavy soils. Feed every two to three weeks with a balanced liquid fertilizer during active growth. Apply chelated iron if leaves show yellowing between green veins. Avoid wetting the crown when watering.

Cut gerbera daisy stems when the outer two rows of petals have opened and the flower center is still tight. Use a sharp knife to cut stems cleanly at the base and place immediately in shallow water, no more than two inches deep, as the hollow stems can become waterlogged and collapse. Support the heavy flower heads with floral wire inserted through the stem if needed. Fresh-cut gerberas last seven to twelve days with proper care and water changes every two days.

Gerbera daisies do not dry well and are best enjoyed fresh. In frost-free zones, plants remain in the ground year-round. In cold climates, container-grown gerberas can be brought indoors to a bright, cool location for winter bloom. The plants need temperatures above 45 degrees Fahrenheit and bright light to continue flowering indoors. Seeds can be collected from mature flower heads and stored for spring sowing, though hybrid varieties will not come true.
