Cotyledons Turning Yellow

Have you recently noticed that the cotyledons on your plants are turning yellow? You’re not alone! Many gardeners experience this frustrating issue. But don’t worry, we’re here to help you understand why this happens and what you can do about it.

First, let’s discuss what cotyledons are. Cotyledons are the first leaf-like structures that emerge from a seed during germination. They provide the initial nutrients for the plant until the true leaves start to grow. Cotyledons are crucial for a plant’s early growth and development.

So why do cotyledons turn yellow? There are a few possible reasons. One common cause is overwatering. When plants are overwatered, their roots become waterlogged, making it difficult for the plant to absorb oxygen. This lack of oxygen can cause the cotyledons to turn yellow and die.

Another possible cause is nutrient deficiency. If a plant is not getting enough nutrients, its cotyledons may turn yellow and fall off. This is especially common in seedlings that have not been given enough fertilizer.

Pests and diseases can also cause cotyledon discoloration. For example, aphids and mites can suck the sap out of cotyledons, causing them to turn yellow and droop. Fungal diseases, such as damping-off, can cause the cotyledons to rot and turn brown or yellow.

So what can you do to prevent cotyledon discoloration? First, make sure you are not overwatering your plants. Allow the soil to dry out slightly before watering again, and make sure your pots have proper drainage. Secondly, make sure your plants are getting enough nutrients by fertilizing them regularly. Finally, keep an eye out for pests and diseases and take action as soon as you notice any issues.

In summary, cotyledon discoloration is a common issue with several possible causes. By understanding the reasons behind this problem and taking preventative measures, you can ensure that your plants grow strong and healthy. Happy gardening!
