How to Care for a Golden Gardenia

The golden gardenia, or Gardenia carinata, is a shrub that can reach a height of 10 feet when it grows in its preferred tropical environment. The leaves are dark green and shiny, like the more familiar Gardenia jasminoides, but the flowers are golden yellow instead of white. Like other gardenias, the golden variety produces highly fragrant flowers from spring through fall. It performs well in a container, which you can keep outdoors from spring through fall; move this plant indoors to protect it from winter frosts.

Instructions

    • 1

      Plant your golden gardenia in an area that receives partial to full sun, where the soil has good drainage. If your winters are cold, grow it in a 12-inch or larger pot with a drainage hole. If you plant it in the ground, amend the soil with one part organic compost to every four parts of soil. If you grow it in a container, use a good-quality potting soil that drains quickly.

      Water your golden gardenia when the soil begins to dry out. To check soil moisture, poke your finger into the soil 1 to 2 inches deep: if it comes out slightly moist, allow the soil to dry a bit longer before you water again. Do not allow your plant to sit in waterlogged soil.

    • 3

      Place a potted golden gardenia plant on a saucer filled with pebbles: keep water in the saucer to increase humidity around the plant.

    • 4

      Fertilize the plant once each month April through October. Use a plant food designed for acid-loving plants, such as azaleas and rhododendrons. Choose a balanced fertilizer in granular form that contains iron.

      Treat most insect pests, such as aphids, spider mites, thrips and mealybugs, with insecticidal soap spray. If scale insects attack, add 1 tbsp. canola oil to each quart of insecticidal soap. The oil smothers hard-bodied insects.

      Move your golden gardenia indoors before fall temperatures drop into the low 30s.
