Gardenality.com's Answer · I always use a slow-release granular plant food on Gerbera daisy. The one I use, GreenView Flower & Bulb Food is a homogenous fertilizer, which means it contains all the essential nutrients in each granual of the fertilizer. I just put it out at planting time in spring and thereafter about every 6 weeks. I don't use the fertilizers that claim they release for 6 months or more because the hot summer sun and water usually degrades the capsule the fertilize is contained in within a much shorter period of time.
Here in mid Georgia, Gerbera daisies will often be perennial if they are planted in very well drained pots or flowerbeds. I've also found that if the soil is allowed to dry out between waterings - to the point that foliage is allowed to start wilting - that the plants think they are dying and will send up more flowers in an effort to create seeds for reproduction. If soil stays constantly damp or moist flowering diminishes and plants will often decline and die.)
