Gardenias are very beautiful ornamental flowers, with large blooms that emit a strong fragrance. We say that flowers need green leaves to make them even more beautiful, but if you are not careful during maintenance, gardenias are prone to yellowing leaves. Today, I will introduce to you the solutions for yellowing leaves of gardenias.
One, Adjust Watering Amount
If you find that the leaves of gardenias are not only yellowing but also drying and falling off, it might be because they haven't been watered for a while. It is important to replenish water in time. You can place the pot in a basin filled with water, allowing the soil to absorb moisture effectively. Additionally, you can spray some water mist on the leaves every few days to keep them moist. If the leaves turn yellow and lose their luster, it might also be due to excessive watering. In this case, you can take the potting soil out and let it dry in the open before replanting it.
Two, Change Soil
If the gardenias' leaves turn yellow after fertilizing, it might be because too much fertilizer was used. If it's not severe, you can water more to let the excess fertilizer flow out with the water. If it's serious, you will need to change the soil.
If the leaf veins are green and the rest of the leaf flesh is yellow, it is possible that the plant is deficient in iron. In this case, you can use diluted ferrous sulfate to spray on the leaves or pour it directly onto the soil, once every half month, and twice should show significant improvement.
Three, Reduce Sunlight
If the leaves of gardenias have yellow spots, it might be caused by exposure to strong sunlight. In this case, you can move it to a shady place for maintenance. Be aware that during the summer when the sunlight is intense, it is necessary to provide appropriate shade, or the leaves may get sunburned.
Four, Fertilize Properly
Gardenias are prone to yellowing leaves due to a lack of iron during cultivation. In this case, it is necessary to apply 0.5% ferrous sulfate solution to supplement iron for the plant. Gradually, the leaves will return to normal.
Five, Temperature Control
Gardenias prefer a warm and humid environment. High temperatures in the summer or low temperatures in the winter can cause the leaves to turn yellow. It is best to keep them in an environment with a temperature of 18-28 degrees Celsius.
