Is it normal for geranium leaves to turn white? What should I do if geranium leaves turn white?

Geranium, also known as hydrangea, is a plant with bright and long blooming flowers. Many people keep one or two pots of it in their gardens. So is it normal for geranium leaves to turn white? What should I do if geranium leaves turn white? The following editor will explain them one by one, hoping to help you.

Is it normal for geranium leaves to turn white?

This is mainly because the temperature is too high, the water evaporates quickly, the pot soil is too dry, and the soluble iron ions in the soil are reduced, which affects the absorption of iron by the roots of geraniums. The iron deficiency of new leaves will affect the synthesis of chlorophyll. If the chlorophyll synthesis is insufficient, the leaves will appear white. The more serious the iron deficiency, the whiter the geranium leaves. When the iron deficiency is not serious, only part of the leaf tissue will turn white and yellow, and the veins will still be green.

What to do if geranium leaves turn white

1. Reasonable iron supplementation

Geraniums like slightly acidic soil. Every month in summer, you can water the geraniums or spray some dilute ferrous sulfate solution on the leaves to ensure that the potting soil is rich in iron and iron deficiency does not occur.

2. Reduce ambient temperature

When the weather is too hot in summer, geraniums should be placed in a cool place for maintenance, such as a north balcony or north window, so as not to let geraniums suffer in high temperatures. Especially when the temperature in some areas is as high as 37 or 38 degrees, it is necessary to cool down the geraniums.

3. Early detection and early treatment

When the new leaves of geraniums turn yellow or white in summer, they must be dealt with in time by watering or spraying with ferrous sulfate once every seven days. Spraying three times in a row will restore the leaf color.

When the new leaves of geranium turn too white, applying ferrous sulfate may not necessarily restore them. It is best to cut them off early to save nutrients and wait for normal new leaves to grow out.

Geranium care tips

Before flowering: Geraniums must ensure appropriate temperature and proper nutrition before flowering. If the temperature does not reach above 15 degrees, it will be difficult to form flower buds. Insufficient nutrition will cause the flower buds to fall off and reduce the number of flowers. Avoid exposure to the sun before flowering and provide appropriate shade.

Flowers: When geraniums are in bloom, you must not apply fertilizer or water them with large amounts of water. Applying fertilizer or watering in large amounts will cause the flowers to fall off.

After flowering: After geraniums bloom, remove the withered buds and dead leaves in time, and replenish nutrients and water in time.
