II. Culture methods of Gardenia jasminoides

1. The soil should be cultivated in acidic soil which is rich in humus and fertile. Generally, rotten leaf soil can be used to add 1 portion of rotten bean cake fertilizer, mixed with a certain amount of ferrous sulfate, or drenched with 0.2% ferrous sulfate or alum fertilizer water for 3 to 5 times.

2. Watering gardenia requires high air humidity. The principle of watering is dry and thorough. It is suitable to be irrigated with soft water in summer, because there are more calcium and magnesium salts in hard water, which is very disadvantageous to the growth of gardenia. In order to overcome the alkalinity of soil and water quality, alum fertilizer was irrigated once a week during the growing season to keep the branches and leaves green. Winter should be controlled watering, do not dry do not water, long-term water content is too much, easy to cause rotten root death.

3. Fertilizing Gardenia jasminoides is not a very fat flower, but because of its exuberant growth, it needs reasonable fertilizer during the growing period. When mature human feces, urine or cake fertilizer is applied every 10 days or so, watering should be stopped one day before fertilization, and permeable water should be watered at the same time on the day of fertilization.

For the above cases, rotten human feces and urine or cake fertilizer can be forced to apply.

6. Changing the basin usually turns the basin once every 1 to 2 years, which is the best in spring to effectively prevent the alkalization of basin soil. When changing the basin, cut off part of the roots, such as disease and insect roots, too numerous roots, and then plant.

Shaping and pruning are generally carried out in spring, cutting off overlong branches, weak branches and other random branches that affect the plant shape in order to keep the plant shape beautiful.
