The Gardenia J. Ellis genus is named after the American amateur florist A. Garden, who lived in the second half of the 18 century and listed about 250 species of plants from the Brooch family. Gardenia are evergreen shrubs that reach the size of small trees.

Subtropical forests of Japan and China.

Gardenia are a very demanding plant, they love year-round diffuse light, heat and high humidity. They slowly adapt when moving to a new location, in the pre-blooming phase, it is enough to rotate the pot by 180 degrees to cause the colored buttons to fall off.

Bright, diffused, without direct sunlight.

Moderate, in spring-summer - 22-24 ° C, in autumn and winter 18 ° C (not lower than 16 ° C).

Depending on the variety and type, as well as the growing conditions.

From spring to autumn, we water heavily after the surface layer has dried. During the winter, gardenia is watered moderately, waiting two to three days after the topsoil has dried. The substrate in which the plant is planted must not be dried or wetted.

Gardenia love high humidity, it is advisable to spray twice or thrice a day. To maintain it, we can put the plant in a pot with a pad of moist sphagnum, expanded clay or clay. It is important that the bottom of the pot is not submerged in water. We can also periodically wipe the leaves of the plant with a damp cloth to wipe away dust and polyps.

Rest period:
 From four to six weeks in the winter, gardenia needs rest. Irrigation should be reduced and nutrition stopped. During this period the gardenias need good lighting, temperatures not lower than 16 ° C and no higher than 20 ° C.


From spring to autumn, young plants are fed twice a month with organic and mineral fertilizers. Mature plants are fed weekly with calcium-free fertilizers.

After blooming, we trim to 1 / 3 from the new undergrowth. During the summer, it is desirable to trim the tips of young twigs to enhance the thickening of the crown.

The soil:
Gardenia like acidic soils, (5 -5.5 pH) loose and nutrient-rich. A slightly acidic substrate is used (as for azaleas) consisting of equal parts coniferous leaf, peat and sand (sand can be replaced by three parts perlite). Over time, the soil is depleted and acidified and normalized. In order to restore optimal acidity, it is necessary to irrigate 2-3 once a month with slightly acidic water, in which a few drops of citric juice or citric acid crystals (per 1 liter of water) are added. Iron sulphate - 0,5 grams per liter is also added. Extra acidity of the soil may be introduced when watering with the water in which we have soaked the peat.

 We only transplant when needed, when the roots firmly fill the entire pot. Gardenia roots grow extremely slowly and frequent transplanting is not recommended to avoid injury.

Reproduction: Through cuttings half-stiff in spring or autumn. In the spring, we cut lengths of about 10 cm in length and plant them in sand (best river) or sand and peat substrate. It is desirable to immerse 4-5 minutes in pale pink solution of potassium permanganate for disinfection before planting. Another method is rooting cuttings in water. Eyelashes should be clogged with a transparent container or plastic bag to provide the necessary humidity while maintaining a temperature of 25 ° C. After rooting the cuttings (about a month), they are transplanted into a substrate of peat, coniferous soil and sand.

Growing difficulties:
During the formation of flower buds does not tolerate large temperature differences. Massive budding of flower buds occurs when the temperature drops below 16 degrees or when dried. With prolonged cloudy weather, flower buds will not open and will fall off. The yellowing of the leaves is caused by more basic (6 and upward pH) soil or temperatures below 12 degrees.
