Causes and treatments of yellow wisteria leaves

1. Too much water

Reason: Wisteria doesn't need a lot of water to grow. If you water too much, the new leaves growing on the top of the wisteria will turn light yellow, the old leaves below will also turn yellow, and then the whole wisteria will slowly wither.

Measures: If you water too much, you need to change the pot and soil, and trim off the rotten roots. You should control the amount of watering on a daily basis and don't water it constantly when you are idle. Then loosen the soil frequently and move it indoors if it rains.

2. Soil drought

Reason: Wisteria prefers fertile and moist soil. If the soil in which it grows is too dry, it will stunt its root growth. Over time, the plant will gradually turn yellow from bottom to top and then fall off.

Measures: If the soil is dry, simply increase the frequency of watering to increase soil moisture, but do not water too much at once.

3. Improper fertilization

Reason: Whether it is due to lack of fertilizer or too much fertilizer, the leaves of wisteria will be uneven and turn yellow. Because of the lack of nutrients, the root system cannot extend and grow normally.

Measures: Control the amount of fertilizer applied. If the growth is slow, add additional fertilizer. If too much fertilizer is applied, dilute the fertilizer by adding water in time. If the situation is serious, the soil needs to be changed and replanted.

4. Soil is alkaline

Reason: Wisteria requires acidic soil for its growth. If the leaves turn yellow because of the soil, it is probably because the soil is alkaline.

Measures: If you want to save trouble, you can directly change to acidic soil, or apply ferrous sulfate to gradually affect the soil quality, allowing the leaves to gradually return to green.

5. Improper lighting

Reason: Wisteria needs sunlight to grow. If it is not exposed to sunlight for a long time indoors, it will cause yellow leaves. If exposed to strong light, yellow leaves may also appear.

Measures: Wisteria can be grown in a place with diffuse light to avoid direct sunlight.
