How to raise gardenia? Its breeding methods and matters needing attention are introduced!

Gardenia is a plant of the genus Gardenia of Rubiaceae. Its leaf color is evergreen all the year round, and it generally blossoms from May to July, with white flowers and fragrant flowers. Besides ornamental, its fruits, leaves and roots can be used as medicine. In addition, gardenia can also be used to make vegetables to eat, flowers can be dried to make tea and drink, and fruits can be used as paint for painting. So, how to raise gardenia? The following is to introduce the breeding methods and matters needing attention of gardenia.

First, how to raise gardenia? Introduction to the culture method of gardenia!

1. Propagation: gardenia can be propagated by sowing, cutting and striping, generally mainly by cutting and striping.

Cuttings can be cut by water or soil, and the survival rate of water cutting is higher. Soil cutting is often carried out in warm places in the south from March to October, and in the north from May to June, and water cutting can be carried out from April to July.

2. Soil: the soil for cultivating gardenia should be acidic.

Gardenia likes to grow in acidic soil. When selecting soil, it is necessary to choose acidic soil with fertile, loose and good drainage, and the soil pH value should be controlled between 4.0 and 6.5.

3. Temperature: the growth temperature of Gardenia jasminoides is 16 ℃-18 ℃.

Gardenia likes warm environment and is not resistant to cold. The suitable temperature for growth period is 18: 22 ℃, and that for overwintering period is 5: 10 ℃. The best growth temperature is 16 ℃-18 ℃. Too high or too low temperature is not conducive to the growth of Gardenia jasminoides. Therefore, it is suggested to choose a well-ventilated indoor for culture.

4. Illumination: gardenia should have plenty of sunshine during its growth.

Gardenia is a plant that loves light, but it can not be exposed to the hot sun. Therefore, it is necessary to increase the light time in spring and autumn, and indoor culture with light is recommended in summer and winter. 60% of the light should be maintained throughout the day in order to meet the needs of its growth.

5. Moisture: gardenia should have sufficient water during its growth period.

Gardenia is a wet plant, and the air humidity should not be less than 70%. Therefore, during the growth period, we should pay attention to increasing the amount of water, and at the same time, we should often spray some water to the leaves.

6. Fertilization: gardenia should be thin and fertilized during the growth period.

Gardenia is a fertilizer-loving plant. In the peak growth period, soybean cake, sesame sauce dregs, peanut bran and other fertilizers can be applied every half a month.

7. Pruning: gardenia should be pruned at the right time.

Gardenia is easy to overlap branches in the growing period, so it should be pruned timely, the jumbled branches and leaves should be cut off during the bud period in April, the residual flowers should be cut off in time to promote new shoots after flowering, and the coring should be carried out when the new shoots grow to 2-3 nodes, and the second stubble branches should be coring again in August.

Second, what are the matters needing attention in breeding gardenia?

1. The alkali content in the soil of cultivated gardenia will make the plant branches withered, leaves scorched, and even die, so it is necessary to prevent soil Alkalization.

2. Gardenia is afraid of strong light, which leads to yellowing, whitening and shedding of leaves. Therefore, it should be maintained in a place with scattered light in summer.

3, gardenia can not accumulate water, in order to avoid rotting roots, do not water the flower when blooming, otherwise it is easy to rot.

4. Gardenia is afraid of thick fertilizer and raw fertilizer, so it is easy to burn roots, and it can not be fertilized during flowering, otherwise it is easy to cause overgrowth of plants, resulting in falling buds and flowers.

5. Gardenia is prone to leaf yellowing disease and leaf spot disease, and insect pests are harmful to diamondback moth, shell insect and whitefly, so attention should be paid to control.

Third, how to maintain gardenia in winter?

Winter weather is cold, gardenia will be dormant, to maintain room temperature between 6-12 degrees, too low easy to freeze damage; even if gardenia dormancy, but also to bask in the sun, 3-4 hours a day, can be a long time without sunlight will cause leaves to turn yellow; winter is also to be watered, but not too much, can be watered once a month, but do not wait until the soil is dry and then irrigated, can not be fertilized.

Are gardenias the same as jasmine?

Gardenia is different from jasmine.

The old branch of gardenia is gray, the old branch of jasmine is brown; the leaf of gardenia is about 12cm, the leaf of jasmine is 3-8cm, and the leaf of gardenia is thicker than that of jasmine; the bud of gardenia is sharp, the flower is one, the bud of jasmine is round, and the flowers are three or more flowers blooming together. The flowering period of gardenia is from May to July, the fragrance of jasmine is like cream, and there are three flowering periods of jasmine. From late June to early July, about early August, and from early September to early October, the flower is like green tea; the fruit of gardenia is oval, relatively large, yellow or orange-red in color, and the fruit of jasmine is spherical, relatively small and purplish black.

The above is the gardenia breeding methods and matters needing attention, and gardenia and jasmine are different, we should pay attention to the distinction.
