What to do if wisteria leaves turn yellow and fall off

Reasons and solutions for the yellowing of wisteria leaves

Overwatering

Many flower lovers, when they have nothing to do, want to communicate with wisteria by watering it and chatting with it, but if they are not careful, the plant may be drowned by their saliva. Wisteria does not require a lot of water every day like humans. If you water too much, the new leaves at the top will turn light yellow, the old leaves will gradually turn yellow, and the plant will become shorter and shrunken. If plants live in an overly wet soil environment for a long time, their roots will easily rot.

Treatment

Loosen the soil frequently, control watering, and try to move the potted wisteria indoors to avoid rain on rainy days.

Soil Drought

Obviously, soil drought means too little watering. The underground rhizomes cannot continue to grow because the soil is too dry and hard, causing the lower leaves to age, but the top leaves grow normally. But as time goes by, the leaves will gradually turn yellow and fall off from bottom to top.

Solution

Watering, of course! But don't water too much at one time. Increase the amount of water gradually and water thoroughly.

Fertilizer deficiency & fertilizer damage

Symptoms of improper fertilization include thin and yellow leaves and an uneven, uneven surface. Long-term lack of fertilizer or excessive fertilizer application will cause the roots to not grow normally.

Treatment

Apply fertilizer appropriately and change pots in time. When the plant grows slowly, add liquid fertilizer in time. However, if the dosage is not controlled well, water should be applied in time to dilute the fertilizer and avoid fertilizer damage!

Alkaline

Wisteria likes acidic soil. Yellowing and leaf falling are caused by alkaline soil.

Solution

Soak the grass on the roadside in water and water it directly, and apply ferrous sulfate as a topdressing, the leaves will gradually turn green. Or simply repot and change the soil to acidic.

Light discomfort

If potted wisteria is kept indoors, the leaves will easily turn yellow due to lack of sunlight. Even if there is plenty of sunlight, if the light is too strong or the high temperature is exposed for too long, the leaves will turn yellow and fall off.

Solution

Normally wisteria does not need shade or shading, but in the south where the summer temperatures are high and the light is strong especially at noon, potted wisteria needs to be properly shaded.
