Extended information:
Gardenia is a typical plants in acid soil. During the breeding process, it should be noted that Gardenia likes fat, so it should be watered more in summer, sprayed with clear water every morning and evening, and sprayed on the ground to cool and humidify when the weather is hot. Avoid sun exposure. Otherwise, the leaves will turn yellow easily, so we should always pay attention to the wettability of the basin soil.
1. Acid-loving soil. Soil, water and fertilizer contain alkali, which makes plants unable to absorb iron, and affects the formation of chlorophyll, causing branches to wither, leaves to scorch and even death. Rich, loose and well-drained acid soil should be used, such as mixing pine sawdust thoroughly into the soil, and the use effect is also very good.
2, like the shade. Don't be exposed to the hot sun, but some people often mistakenly think that gardenia requires full shade, which leads to mistakes in cultivation. In fact, while paying attention to cultivating its cool environment, it is necessary to maintain 6% light all day to meet its growth needs.
3. Humidity preference: If the air humidity is lower than 7%, it will directly affect flower bud differentiation and flower bud growth, but excessive humidity will cause root rot, branches wither and leaves fall off.
4. Fertilizer-loving: It is advisable to apply fertilizers such as cooked bean cake, sesame sauce residue, peanut bran, etc., which can be acidic after fermentation and decomposition, but it is necessary to apply more thin fertilizers, avoid thick fertilizers and raw fertilizers, and do not apply fertilizers during hibernation. If it has been planted for less than three years, it is forbidden to apply human excrement and urine.
5. Temperature preference: 18℃ to 22℃ in the growing period, 5℃ to 1℃ in the wintering period, and it is easy to be frozen below -1℃.
6. Timely pruning: Gardenia has strong germination, easy overlapping of branches, airtight and scattered nutrition.
