All this is further explained here. Similarly, what is the best fertilizer for gardenias?
Acid-Loving Plants Gardenias prefer acidic soil with a pH around 5.5. Some fertilizers, like blood meal, cottonseed meal and fish emulsion, can help acidify soil and maintain a low soil pH. These fertilizers for acid-loving plants are the best choice for gardenias.
Furthermore, what do you feed a gardenia? Gardenias use a lot of nutrients to produce so many glorious blossoms. Feed your shrubs by applying an acidic, slow-release fertilizer such as an azalea or camellia fertilizer. For the organic gardener, blood meal, fish emulsion or bone meal work well.
Similarly, you may ask, can gardenias be potted?
Gardenia grows best in U.S. Department of Agriculture plant hardiness zones 8 through 10 , but you can enjoy these aromatic beauties indoors with little effort. With adequate water, sufficient drainage, an acidic soil and plenty of sunlight, gardenias can grow just as well in pots as they do planted in the ground.
How often should I water a potted gardenia?
Monitor the soil for dryness, especially when the plant is in bloom. If rainfall is insufficient, give gardenia plants about 1 inch of water per week, but more often if roots dry out quickly. Do not flood the roots. If rainfall is limited, shrubs growing near heated buildings may need more water.
