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.
However, it takes the right kind of fertilizer applied at the proper time to get the job done. Gardenias love acid-rich soils, and the soil pH should be between 5 and 6, with an ideal of 5. Before applying fertilizer, have the soil pH tested. If the pH is higher and on the alkaline side, or above 7, a soil acidifier helps bring it back to the level gardenias love. Gardenias need fertilizer during their growth cycle to support development and fuel growth and flowering.
Flowering is part of the reproductive cycle of plants. Plants expend a great deal of energy creating baby plants!

Mulch plants with a 2- to 3-inch deep layer of pine straw, compost or ground bark.
Fertilize gardenias lightly in the spring once frost has passed with a well-balanced, extended-release, acid-forming, azalea fertilizer. Fertilize the shrubs again 6 weeks later to encourage extra flowers or faster growth of young shrubs.
By well-balanced, this means to look for nutrients in the ratio of Fertilizer examples are:. Complete, acid-forming organic fertilizers are also excellent choices for use on gardenias for spring and early summer fertilization. They are typically not as nutrient rich, and because of both the low nitrogen content and their inability to burn the roots, they can be mixed lightly into the soil in the fall at planting to enhance root growth. Organic fertilizer examples are:.
This is also a good time to prune any leggy growth. Gardenias should be fertilized three times a year in spring, summer and early fall, applying the amount recommended on the fertilizer label or slightly less. Since gardenias are evergreens, they will continue to grow all year if protected from frost, but they should be given a rest from fertilization during winter months. When applying fertilizer, water the plant lightly first; applying fertilizer to a dry plant may harm the roots.
Gardenias prefer a slightly acidic soil pH of 5. To correct the soil pH, once a month water the gardenia with 1 tablespoon of white vinegar mixed into 1 gallon of water.
