Many people like to grow gardenias in their daily life. Gardenias have lush branches and leaves, evergreen leaves, simple and elegant flowers, green leaves and white flowers, which are very beautiful and lovely. They can be planted in the courtyard or made into potted plants and placed indoors. However, when people grow gardenias, they often encounter yellowing leaves. So what is the reason for the yellowing of gardenia leaves? How to solve the problem of yellowing gardenia leaves?

1. Improper watering

Improper watering is one of the main reasons for the yellowing of gardenia leaves. Especially when people water the gardenia too much, the inner part of the gardenia will become dark yellow and dull, while the old leaves will be almost unaffected. If the leaves turn yellow due to this reason, the gardenia should be placed in a cool and ventilated place in time, and the soil in the flowerpot should be slightly dry before putting it back. If the gardenia is lacking water during cultivation, the leaves will also turn yellow. At this time, it should be watered thoroughly in time.

2. Unreasonable lighting conditions

Unreasonable light conditions are also the main reason for the yellowing of gardenia leaves. Especially when the light is too strong, the leaves of gardenia will not be fully exposed to the sun and red spots will appear. At this time, you should move it to a cool place for maintenance in time, so that the leaves can slowly recover, and the new leaves that grow will not have yellow spots. When there is insufficient sunlight, the leaves of gardenia will turn yellow or even fall off. At this time, you can move the gardenia to the sun and supplement it with sufficient sunlight.

3. Improper fertilization supply

The amount of fertilizer you apply to gardenias is also very important. If you apply too much fertilizer or too little fertilizer, it can cause the leaves to turn yellow. If it is too much fertilizer, the top will turn yellow easily. At this time, you should stop fertilizing. If it is serious, you should also flush the soil to reduce the concentration of fertilizer. If the leaves turn yellow due to insufficient fertilizer, you can add fertilizer in time. If the leaves of gardenias turn yellow due to iron or magnesium deficiency, you need to add these trace elements in time.
