1, soil. For gardenia, the soil environment is very important because it has a preference. It likes to grow in a slightly acidic environment, and it is necessary to choose the soil before planting flowers. Generally, we need to control the pH value of flower soil in the range of 4.0 to 6.5.

2. temperature. We also need to control the temperature. Its optimum growth temperature is between 16 and 18. Because temperature is the key, it should be well preserved. If there is no suitable temperature, the growth of gardenia will be hindered. In addition, it is necessary to pay attention to ventilation conditions and maintain good ventilation to make it grow well.

3. Moisture. We need to remember to water it often and sprinkle some on its leaves, which will help us raise gardenias. In addition, we need to adjust the humidity in the air. Of course, it will be more difficult to raise gardenias in winter. Be sure not to water it too much, lest the gardenia rot.

4. Lighting. Because gardenia loves light, we must provide it with enough light. In spring and autumn, the light time can be appropriately increased to make it grow better. In summer and winter, although it should be kept indoors, light is still indispensable, which is a good way to raise gardenias.

5. fertilizer. Nutrition is equally important to it, and it must be provided with sufficient nutrition to raise it well. When it grows fast, it should be fertilized once every half month, and bean cake or sesame sauce residue can be used as flower fertilizer.

Step 6 trim. Because of the complexity and overlap of some branches, the growth of gardenia will also be affected, so pruning is needed to raise gardenia well. Only in this way can we raise it well.

Second, gardenia in the pot:

1, open the pot and trim the roots. When I got home, I removed the original disposable basin and saw that the roots were full and there were many white roots. At this time, I will break the root by hand and divide it into four parts, so as not to hurt the root as much as possible.

?

2. Prepare the soil for the basin. Prepare pot soil, you can dig a little under the pine tree, which is breathable, acidic and drainage. Put the seedlings into the pot, shake the seedlings and add soil until the soil reaches 2/3 of the pot, and press with your hands to ensure the soil is practical.

3. Dip the basin and then water it. Soak the planted flowerpot in water and take it out after ten minutes. Wash the soil off the leaves with a sprayer.

4. Pruning and maintenance. Cut off the weak branches of gardenia to reduce the burden on the roots. Move the flowerpot to a cool and backlit room for 5 days, and then move it to a place with scattered light for 10 days. If there is water shortage during this period, water should be supplied in time, and a little fertilizer should be applied after half a month.

Matters needing attention in gardenia cultivation:

1. After winter, let gardenias cool for 1 month to pass the dormancy period, then move them indoors, and keep the room temperature above 18℃ by increasing the temperature and supplementing the light, which can promote gardenias to bloom in winter and spring and can be widely used as materials for various bouquets. ?

2. After planting, root water should be poured in time to keep the air and soil humidity high, but no water should be accumulated to avoid root rot. Before flowering, the management of fertilizer and water should be strengthened, and the principle of thin application and diligent application should be implemented.

3. The row spacing of plants depends on the purpose of producing gardenia. Generally, the depth and width of cut flowers and planting pits in public places are about 50cm, so it is best to plant them during dormancy. If you need to plant in the growing period, it is best to bring a lump of soil to ensure survival. ?

4. Gardenia in the open field has strong adaptability, extensive cultivation management and easy success. It is advisable to choose acidic and slightly acidic soil with abundant sunshine but not easy to be exposed to direct sunlight, fertile and loose soil and good drainage for cultivation. The technical requirements of soil preparation, box opening and base fertilizer application are the same as those of other flowers. ?

5. Gardenia pruning is mostly done in early spring. After each new shoot, you should pick the heart and divide one branch into three branches to form a fast crown and many flowers. At the same time, cut off too many branches in the inner room. When the flowers in each season are about to wither, it is necessary to remove the residual flowers in time, which is conducive to the differentiation of flower buds in the next season, and it is better to spend more.
