The cause of yellowing of Gardenia jasminoides leaves and its control

Gardenia is a relatively common kind of flower, which is planted by many flower growers. Because it is mainly sold as ornamental plants, its appearance needs to be paid attention to. So to some extent, the yellowing of gardenia leaves has a great impact on flower growers. Let's take a look at it with Xiaobian.

1. Moisture

The amount of water will have a great impact on the leaves of Gardenia jasminoides, because the yellow leaves caused by water will have different performance due to the amount of water. More water, its leaves show a kind of water yellow, darker color, caused by the lack of water is dry yellow, the color is lighter, looks very thin. In this case, just control the watering. It is suggested that florists should manage gardenia in this situation separately until they are ready and then send them back to the shed.

2. Lighting

Now many flower growers build cultivation sheds for better lighting, their light transmittance is generally better, but they do not do enough in sunshade. Gardenia is not suitable for long-term exposure to the sun, generally the afterlight of the sun is the best. If you find that the leaves turn yellow after a period of exposure, or after long-term exposure for a certain period of time, it is best to move to a place that is out of direct sunlight and observe for a period of time. Then shade is installed in the breeding shed to prevent it from withering.

3. Fertilizer

Fertilizer is also one of the reasons for the yellowing of gardenia leaves, because the demand for fertilizer of gardenia is not so obvious, so flower farmers will use it improperly when fattening. If there is too much fertilizer, there will be a situation of burning seedlings, and if there is not enough fertilizer, it will show that the plant will wither. In this case, the cultivated soil needs to be changed, but not if there is a lack of fertilizer, because in the case of fertilizer accumulation, it is difficult for gardenia to absorb the excess residual fertilizer.

Gardenia is a relatively fragile plant, so the daily management is that florists need to be careful. If there is a situation once, we had better be on guard to avoid a second time. In general, the yellowing of leaves has little effect on the plant, just adjust it in time, but if it is caused by disease, florists should pay attention to it.
