Because of their beauty and aroma, gardenias are plants many people would like to grow in their homes. But they are very picky about growing conditions and often difficult to keep alive in a dry and shaded house. Given the right tools and the proper care, however, gardenias can be grown in virtually any home.
Gardenias are evergreen shrubs. Their leaves are shaped like ovals, dark green and glossy. They have white flowers and waxy petals. They can get up to 6 feet tall. When the gardenia is not cared for, the leaves can turn yellow and even drop off. In a vulnerable position, gardenias are likely to be attacked by pests.
Set the thermostat between 68 and 74 degrees in order to create an ideal temperature for gardenias. A humidifier can help the gardenia plants by making sure the room does not become too dry, according to Purdue University.
In small indoor spaces, gardenias might need to be pruned. If flowers are pruned right after they stop blooming, they will bloom more often, according to Purdue.
The soil gardenias grow in must be loose, organic and contain plenty of nutrients, according to Purdue. The pot the gardenia is kept in must drain well, and peat moss can be used to help the soil retain moisture. Any tray the water drains into should be emptied out. Too much moisture can cause flowers to drop, encourage mold and even draw pests into your home. But dryness will also cause gardenia flowers to drop. The leaves should not be misted; this can cause fungal leaf spot.
Gardenias must have full sun when grown indoors, since they need as much sunlight as they can get, according to Purdue. They should be placed by a window in a spot where no sunlight is blocked. If there is not enough sunlight, use grow lights.
In addition to making the inside of the home more attractive, gardenia plants benefit homeowners by improving the moisture and air quality within the home, according to Utah State University. The gardenia is also very aromatic, so this plant will not only create pleasant smells but can also mask bad ones.
