Reasons That Answer Why Do Geranium Leaves Turn Yellow

Geranium offers that beauty you expect from a plant. It offers a better view and fresh smell with relatively much lesser care. But sometimes, it needs to be given proper care.

These can be the times of seasonal changes or the plant’s blooming phase. Below are four reasons to answer why do Geranium leaves turn yellow.

1)    Sunlight Issues

Sunlight is an essential aspect to consider while looking for the reasons to why do Geranium leaves turn yellow. If the plant doesn’t get proper sunlight, it impacts the growth leading to yellow leave. Having said that, just don’t run straight out to place your Geranium in the sun yet.

You might have planted Geranium indoors, which restricts the plant from receiving enough sunlight. If so, this goes on to make the plant crumble more towards the top.

While looking for good sunlight for your Geranium, always consider the morning sun. Geranium demands a minimum of four to six hours of morning sunlight for proper growth.

It is not recommended to put the plant in direct sunlight during mid-day. This will keep Geranium dehydrated, eventually turning the plant’s leaves yellow.

2)    Watering Issues

Be it any plant or a Geranium, too much water is not good. Similar is the case also when the water is less.

Geraniums display identical signs and symptoms along with other plants when overwatered. So, if you are overwatering your plant, it might turn pale pretty soon. This is because the plant cannot digest too much water.

On the flip side, underwatering the plant means it will remain dry for a long time. You will quickly notice the dryness in the plant if you are underwatering it. Hence the edges of the leaves start to turn yellow but not the whole plant. 

If you are worried about the right time to water your Geranium plant, just check the moisture in the soil of the plant by sticking your finger. You will find out whether to water your plant or not. If the soil is dry, it needs water. Easy. Isn’t it?

3)    Diseases

If we talk about the diseases in a Geranium plant, it tends to catch diseases pretty soon. Geranium is one of those plants that get diseased quickly.

To be precise, four types of disease might affect the plant. They are Bacterial Blight, Bacterial Lead Spot, Southern Bacterial Wilt, and other Viral infections.

Also, these diseases spread rapidly in the Geranium plant. You must be aware of isolating your plant from these diseases pretty quickly.

But if your plant is badly affected already, there is no option other than to abandon the plant. If not done so, it might affect other plants in your garden too.

4)    Lack of Nutrients

To answer your query as to why do Geranium leaves turn yellow, it is also due to the lack of nutrients available for the plant. Your plant might be deficient in essential nutrients required for the good growth of the plant. This leads your Geranium to turn partially or fully.

If you’re confused about what nutrients to use for your Geranium, go for the use of Magnesium. Magnesium will help fuel the chlorophyll in your plant bringing back the green pigment.

Also, check the pH value of the soil. Poor knowledge of soil pH value leads to your plant’s failure in good growth.
