How to raise gardenia in autumn

1. Lighting

Gardenia can not be exposed to the hot sun, nor can it be completely overcast. Generally speaking, the light in autumn is not particularly strong. But sometimes the light at noon is also very strong, so it should be sheltered properly. When the other light is not strong, you can accept the light. The light intensity should be kept at about 60%.

2. Humidity

What we're talking about here is humidity in the air. Not less than 70%, or there will be problems with the growth of the plant. In addition to spraying the surface of the leaves, you can also spray the ground.

3. Fertilizer

There are many kinds of fertilizers available, as long as they are fermented. Such as bean cake, peanut butter and so on. Pay attention to the comprehensive variety of fertilizers. If only nitrogen fertilizer is used, it is not easy to blossom; if there is too much phosphate and potash fertilizer, it will also cause flowers to fall off.

4. Temperature

Preferably in the range of eighteen to twenty-two degrees. Autumn can generally meet the needs, if the occasional temperature is too high, then adjust.

5. Pruning

Branches tend to be dense, so their nutrients are not enough. Generally speaking, especially after flowering, a pruning should be carried out to shorten most of the branches, which is conducive to later growth.

6. Prevention and control of diseases

Chlorosis is easy to appear, which will affect the formation of chlorophyll. Generally speaking, it is caused by iron deficiency. It can be replenished with molten ferrous sulfate and used every ten days or so.
