Gardenias require at least an inch of rain (or equivalent watering) each week. (If planted outside) apply a 2- to 4-inch layer of organic mulch to help keep soil moist, reduce weeding, and maintain a constant soil temperature. Feed monthly during the growing season with an acidifying fertilizer. Prune in early spring to shape the bush, and deadhead after flowering to encourage more flowering. Check periodically for white flies and mealybugs, using a horticultural oil or insecticidal soap to control these pests. In regions where the plant is marginally hardy, protect bushes from hard freezes and drying winter winds. Any fertilizer for Azeleas will work well for Gardenias
