What Causes Leaves To Turn Yellow?

Are you singing the tune “Yellow Submarine” after witnessing your plants turning yellow? Don’t worry, it’s not your gardening skills that are failing you. The yellowing of leaves is a common problem and can be caused by various factors. In this article, we will delve into the causes of this problem and give you tips on how to prevent your plants from turning yellow.

1. Overwatering

Overwatering is a common cause of yellowing leaves. When you overwater your plants, the soil becomes waterlogged, and the roots don’t receive enough oxygen. As a result, the roots start to rot, and the leaves turn yellow. To prevent this from happening, water your plants only when the soil is dry to the touch.

You can check the moisture levels of the soil by sticking a finger in the soil to about 2-3 inches. If it’s dry, it’s time to water your plants.

2. Lack Of Nutrients

Another reason for yellowing leaves is the lack of nutrients. In this case, the plant is not receiving enough minerals like nitrogen, potassium, and magnesium, that are essential for growth. This can be easily remedied by fertilizing your plants regularly.

You can use organic fertilizers or even compost to provide your plants with the necessary nutrients.

3. Pest Infestation

Pests like spider mites and aphids can also cause yellowing of leaves. These tiny creatures feed on the sap of the plant, depriving the leaves of nutrients. You can get rid of them by using natural pest control methods like neem oil or insecticidal soap.

4. Exposure To Extreme Temperatures

Exposure to extreme temperatures can also lead to yellowing of leaves. If your plant is exposed to high temperatures, the leaves will lose moisture rapidly, leading to dehydration and yellowing. Similarly, exposure to cold temperatures can also cause the leaves to turn yellow.

To prevent this, make sure your plants are placed in areas with the appropriate temperature range.

5. Old Age

Finally, yellowing could just be a natural part of the plant’s life cycle. As plants age, the leaves start to deteriorate, and eventually, fall off. This is normal, and you don’t need to do anything about it.

The Bottom Line:

Yellowing of leaves can be caused by various factors, but the good news is that most of these issues can be easily identified and remedied. By watering your plants correctly, fertilizing them regularly, protecting them from pests, and ensuring they are placed in the right location, you can prevent your plants from turning yellow.

So next time you hear your plants singing “Yellow Submarine,” you’ll know exactly what to do. Happy gardening!
