Why do the leaves of the fragrant vine turn yellow?

1. Phellodendron chinense

If its leaves turn yellow because the tips and edges of the leaves become dry and withered, and the old leaves start to turn yellow from the bottom to the top and even begin to fall off, and the new leaves grow better, then it can be determined that it is suffering from lack of water and drought. Generally, we should pay attention to watering and water enough each time.

2. Lack of fertilizer and yellowing

If the new leaves are dull in color, such as yellow or light green, while the old leaves are normal color or have turned from green to yellow, it can basically be concluded that it is lacking fertilizer. We need to check to see if the soil is dry and hard. If this symptom occurs, you can consider changing the soil. In addition, apply fertilizer in small amounts and more frequently, and you can add some alum water.

3. Lack of light yellow

If we often put it in a very dark place, its leaves will not get sunlight and it will be difficult to form chlorophyll. The leaves of the whole plant will gradually turn yellow and then begin to fall. Generally, we need to supplement it with light, which can alleviate the problem.

4. Fat and yellow

If we give it too much fertilizer or the concentration is too high, it may cause its leaves to turn yellow. Generally, the tops of the newly grown leaves will appear dry brown, and the leaves will be thicker but lack luster. In addition, it will be bumpy and unable to unfold, and the old leaves are likely to fall off. At this time, we should no longer fertilize, and if the condition is more serious, we should wash it with plenty of water.

5. Burn yellow

This is mainly because it is directly exposed to strong sunlight. Generally, it manifests itself in the dryness of the tips and edges of its leaves, and yellow spots on the leaves facing the sun, so we have to move it to a cooler place.

6. Water yellow

If the new leaves are yellow and dull, while the old leaves are normal, the branches are very thin and also yellow, and the new shoots are shriveled, this means that you have watered too much. Generally we need to take it out of the pot, let it dry in a cool place and then put it back.
