What to do if geranium leaves turn yellow

Normal update

If you are raising geraniums for the first time, you may not have much experience. The newly grown small leaves may be dull in color, which is normal and will recover after a while. There is another situation where the plant grows well, but the leaves close to the soil begin to turn yellow and fall off. This is the normal metabolism of the plant. Don't worry.

Sudden environmental changes

Many flower lovers will move geraniums when the temperature changes, moving them from outdoor flower stands to indoors, or from the south balcony to the north balcony, or from the full-sun outdoor to the corridor, etc. In these cases, the sudden change in the maintenance environment will cause the old leaves of the geraniums to turn yellow and the flower buds to dry up. As long as the dead leaves are cut off in time, the plant will adapt and recover naturally after a period of time.

high temperature

In summer, the leaves turn yellow, affecting the normal growth of the root system. The main reason is that the environment is hot and stuffy, and the roots cannot absorb nutrients from the soil, causing the new leaves to turn yellow. In severe cases, dead spots appear and they gradually burn and fall off. There is no need to worry about this situation. You can spray and water the plant with iron solution once a week. The plant will basically recover after three waterings. In addition, if you cool down and ventilate appropriately, the leaves will slowly recover.

Improper watering

Watering too frequently or not watering for a long time will cause the leaves of the plant to turn yellow. If you water too little and the soil in the pot is dry, the leaves of the geranium will turn yellow and fall off from the bottom to the top. In severe cases, the petioles will droop and wilt. If you water too much and the soil in the pot is wet, there will be no obvious changes in the old leaves and the young leaves will turn light yellow. In severe cases, the roots will rot and the plant will die.

Water in moderation. If you water too much, place the flower pot on newspaper or peat to absorb excess water. Or you can directly remove the pot, dry the plant, and replant it.

Diseases

Pests and diseases are also important reasons why geranium leaves turn yellow. When geraniums are infected by fungi or viruses, they will develop various leaf spot diseases and gray mold, causing the leaves to lose their green color and develop spots. The same phenomenon occurs when the plant is infested by pests and diseases. Actual spraying of pesticides is required for prevention and control.
