Why are the leaves of gardenia turning yellow?

1. Too much water

Reason: Most plants will have many problems if they are in a waterlogged environment for a long time. The same is true for gardenias. Their leaves will turn yellow when they are in waterlogged.

Solution: Reduce the frequency and amount of watering, and change the watering method. If you water it normally, you can wait until the soil is completely dry before watering it, and just water it thoroughly.

2. Iron deficiency

Reason: Pay attention to fertilizing on a regular basis. If the plant is deficient in iron, the leaves will turn yellow.

Solution: Apply fertilizer containing iron to it in time. When maintaining it, you can apply ferrous sulfate diluted with 300 times of water and then spray it. Water it once every half a month for two months, and apply it once a month in the later stage.

3. Lack of sunlight

Reason: When the plant is in a dark environment for a long time, it cannot form more chlorophyll without light, and its leaves will easily turn yellow or even fall off.

Solution: Move it to a location with good lighting conditions in time for maintenance. Light is indispensable for plant growth, and it should receive about four hours of light every day.
