Growing Gardenias, Caring for Gardenias, Planting Gardenias


Beloved for their intoxicating fragrance and attractive, waxy, creamy-white flowers contrasting beautifully with their shiny, leathery, dark green leaves, Gardenias are irresistible heat-loving evergreen shrubs or trees. Native to the tropical and subtropical regions of Africa, southern Asia, Australasia, and Oceania, Gardenias are not the easiest shrubs to grow, but their exquisite fragrant flowers make up for the extra attention they require.

Gardenia Requirements

Gardenias are beautiful subtropical plants that may be fussy and quite temperamental in their cultural needs. To grow them with success, make sure you follow the below requirements.

  • Select a site with full sun to light shade. Although a Gardenia plant prefers full sun, some shade is appreciated during the warmer months of the year or its leaves may scorch and its buds may fall off if they get too much sunlight. In hot climates, Gardenias grow best with morning sun and afternoon shade. In cooler areas, they can tolerate full sun, especially if their roots are covered with organic mulch. Gardenias growing in containers need a bright light or filtered shade with no direct sun. Gardenias grown indoors should receive at least 6-8 hours of direct sunlight through a sunny window.
  • Make sure your Gardenia soil is moist and well-drained. Gardenias need at least 1 inch of rain (or equivalent watering) each week. Keep the soil consistently damp but not soggy. Don't let the soil dry out and don't over-water your Gardenias or the flower buds will not open and may even drop off. Apply a 2-4 in. layer of organic mulch (5-10 cm) to maintain the soil moist and keep a constant soil temperature. In order to drain away excess fertilizer salts in the soil, water with distilled water once a month.
