Why do geranium leaves turn yellow in summer?

Geranium's leaves turn yellow due to environmental changes

When growing geraniums, the leaves will turn yellow due to changes in the environment. Many people will move geraniums to a cooler place indoors for maintenance in the summer, which will cause the growth environment of geraniums to change, causing the old leaves to turn yellow and the flowers to dry up.

This problem is easy to solve. After the geranium is able to adapt to the new environment, just cut off the yellow and dried flowers.

Geranium leaves turn yellow due to high temperatures

In the summer, the temperature is very high, so it is easy for geranium leaves to turn yellow. Generally, it is because of the high temperature that the roots of the plant can hardly absorb nutrients normally, and the leaves turn yellow due to iron deficiency.

At this time, you can spray some iron solution on the geranium, or lower the temperature of the environment, and wait for the leaves to slowly recover.

Geranium leaves turn yellow due to watering

In summer, improper watering can easily cause yellow leaves. Whether it is too dry or too waterlogged, yellow leaves are very common, and in severe cases the leaves may even fall off.

In summer, watering of geraniums is very important. You should pay attention to the watering method, alternating between dry and wet, avoid excessive watering, and avoid not watering for a long time.

Geranium yellow leaves after fertilization in summer

Fertilization can easily cause geranium leaves to turn yellow in summer, because if there is insufficient nutrition in the summer, it is easy to cause yellowing due to starvation, while excessive fertilizer can also cause yellowing. When fertilizing geraniums, we must pay attention to the plant's demand for fertilizer and not fertilize blindly to avoid causing adverse phenomena such as yellowing of the plant's leaves.

Geranium leaves turn yellow due to pests and diseases

Pests and diseases are prone to break out in the summer, and geraniums are also easily harmed by them, causing their leaves to turn yellow. At this time, you should pay attention to preventing and controlling diseases and insect pests to prevent the plants from being harmed and the leaves from turning yellow.
