What causes the yellowing of roses and gardenias leaves
Many rose and gardenia enthusiasts have encountered the situation of yellowing leaves. In fact, yellowing leaves are a "warning signal" that the plant's body is having a problem, just like a person getting a cold and having a runny nose. Therefore, when encountering yellowing leaves on roses and gardenias, never ignore them.
1. Excessive watering
The first possible reason for yellowing leaves on roses and gardenias is excessive watering, which causes root积水 and root rot, and the leaves gradually turn yellow. At this time, you must stop watering and place the plant in a shady and well-ventilated area for maintenance. Trim the bad leaves and branches, and wait for it to recover slowly.
2. Insufficient soil acidity
In addition to excessive watering, there is another important reason, which is the insufficient acidity in the soil. At this time, we can add a little lemon acid to the water and water the plant once every half a month. Not only will the yellow leaves quickly turn green, but the buds of gardenias and roses will also sprout wildly. Or you can also use some ferrous sulfate, dilute the ferrous sulfate with a proper amount of water, and then pour it directly into the potting soil of roses and gardenias. After using it several times, it can greatly reduce the chance of yellowing leaves.
The "antidote" to yellowing leaves of roses and gardenias is lemon acid water and ferrous sulfate, which both roses and gardenias love. Use it several times to turn yellow leaves into green leaves.
