If you have a variegated arrowhead plant and you’ve noticed that some of its leaves are turning yellow, you may be wondering what’s causing this problem. There are several possible reasons why your plant’s leaves are turning yellow, and in this article, we’ll explore some of the most common causes and provide tips on how to fix the issue.
Overwatering is one of the most common causes of yellowing leaves in houseplants, including variegated arrowhead plants. When you water your plant too frequently or give it too much water at once, the soil can become waterlogged, depriving the roots of oxygen. This can cause the leaves to turn yellow and eventually fall off.
To avoid overwatering your variegated arrowhead plant, make sure to let the soil dry out slightly between waterings. Stick your finger into the soil about an inch deep – if it feels dry, it’s time to water. Also, make sure that your pot has drainage holes so that excess water can escape.
On the other hand, if you’re not watering your variegated arrowhead plant enough, its leaves may also turn yellow. When a plant is underwatered, its leaves become dry and brittle, eventually turning yellow before falling off.
To avoid underwatering your plant, make sure to water it regularly, using the finger test mentioned above to determine when it needs water. If your plant is in a small pot or in a hot room, you may need to water it more frequently than usual.
Another reason why your variegated arrowhead plant’s leaves may be turning yellow is that it’s not receiving enough nutrients. This can happen if you haven’t fertilized your plant recently or if it’s been sitting in the same soil for a long time.
To remedy this, you can fertilize your plant with a balanced fertilizer every two to three weeks during the growing season (spring and summer). You can also repot your plant in fresh soil every year or so to provide it with fresh nutrients.
Sometimes, pests like spider mites or aphids can infest your variegated arrowhead plant, causing its leaves to turn yellow. These pests feed on the plant’s sap, which can cause the leaves to become discolored and eventually fall off.
To get rid of pests on your plant, you can try spraying it with insecticidal soap or neem oil. Make sure to follow the instructions carefully to avoid damaging your plant.
Finally, if none of the above reasons seem to apply to your variegated arrowhead plant, it’s possible that it’s suffering from a disease. Root rot, caused by a fungus called Pythium, is a common disease that can affect arrowhead plants and cause their leaves to turn yellow.
If you suspect that your plant has a disease, you may need to consult a professional for advice on how to treat it.
In conclusion, there are several reasons why your variegated arrowhead plant’s leaves may be turning yellow, including overwatering, underwatering, lack of nutrients, pests, and disease. By identifying the cause of the problem and taking appropriate action, you can help your plant recover and thrive once again.
