1. Causes and measures1. The first situation is that the leaves lack iron, so the green of the leaves is not a very fresh green and may even be slightly yellow. In severe cases, the leaves will wither and the whole tree is likely to die. If this is the case, you can spray some iron supplement solution at a ratio of 0.2 to 0.5%, which can successfully prevent and control it. 2. The second situation is a lack of magnesium, which can cause chlorosis, spreading from older leaves to newer leaves. Although the leaves are still green, they will dry up and fall off in severe cases. If this is the reason, you can spray some 0.7 to 0.8% boron magnesium fertilizer. 3. The third situation is lack of nitrogen. In this case, its leaves will become withered and yellow, and the leaves will grow very small and brittle. If this is the case, apply nitrogen fertilizer in a gradient. 4. The fourth situation is a lack of potassium, in which the leaves turn from green to brown. In these cases, the leaves look like they are dead. If this is the case, apply potassium fertilizer in a gradient. 5. If there is too much water or the temperature is too low, it will be frozen and the leaves will dry out easily, so you must take good care of it. If this is the case, you should change the soil and increase the temperature in time and take good care of it. 2. Precautions1. This flower prefers acidic soil, which allows it to grow lushly. If your home is in the north, the soil is mostly alkaline, so the leaves of your home will easily turn yellow or wither. Therefore, if you buy gardenia, you must use acidic soil to cultivate it. 2. If it is summer, the sunlight is very strong and its branches and leaves are easily sunburned. If it lasts too long, the damaged leaves will wither. So you should place it in a semi-shaded area, and don't pour water directly on it. You can spray water on the leaves. Generally, it will regain its vitality in about 15 days. If all the leaves of your tree have withered, there is no way to save it. 3. If the leaves of your tree dry up, you need to readjust your care methods. Always pay attention to the condition of its roots. Don't water it all the time. Wait until the leaves stretch out and then resume normal care. |
