Why Are Your Arrowhead Plant Leaves Turning Yellow:
Causes and Solutions

Arrowhead plants are popular houseplants that are prized for their attractive foliage. These plants are relatively easy to care for, but one common problem that many people encounter is yellowing leaves. If you have noticed yellowing leaves on your arrowhead plant, don’t panic. In this article, we’ll explore the most common causes of yellowing leaves on arrowhead plants and provide you with some solutions to help you keep your plant healthy and thriving.

Common Causes of Yellowing Leaves on Arrowhead Plants

1. Overwatering

One of the most common causes of yellowing leaves on arrowhead plants is overwatering. Arrowhead plants prefer moist soil, but they do not like to be sitting in water. When a plant is overwatered, the roots become waterlogged and cannot absorb oxygen properly. This can cause the leaves to turn yellow and eventually die.

2. Underwatering

On the other hand, underwatering can also cause yellowing leaves on arrowhead plants. When a plant does not receive enough water, it will start to wilt and its leaves will turn yellow. This is because the plant is not receiving enough moisture to support its growth.

3. Lack of Light

Arrowhead plants require bright, indirect light to thrive. If your plant is not receiving enough light, its leaves may start to turn yellow. This is because the plant cannot produce enough chlorophyll without adequate light.

4. Pests

Pests such as spider mites and mealybugs can also cause yellowing leaves on arrowhead plants. These pests feed on the sap of the plant, which can cause the leaves to turn yellow and eventually fall off.

Solutions for Yellowing Leaves on Arrowhead Plants

1. Adjust Watering

If your arrowhead plant is suffering from overwatering or underwatering, adjust your watering schedule accordingly. Make sure that you are not watering your plant too frequently or too little. Allow the soil to dry out slightly between waterings and make sure that the pot has proper drainage.

2. Increase Light

If your arrowhead plant is not receiving enough light, move it to a brighter location in your home. You can also consider using artificial light sources such as grow lights to supplement natural light.

3. Treat Pests

If pests are causing yellowing leaves on your arrowhead plant, treat them immediately with an insecticidal soap or neem oil spray. Make sure to follow the instructions carefully and repeat treatment as needed.

FAQ

Q: Can I save my arrowhead plant if its leaves have already turned yellow?

A: It depends on the severity of the damage. If only a few leaves have turned yellow, you can remove them and take steps to correct any underlying issues (such as overwatering). However, if most of the leaves have turned yellow and the plant looks wilted or limp, it may be beyond saving.

Q: How often should I water my arrowhead plant?

A: Arrowhead plants prefer moist soil but do not like to be sitting in water. Water your plant when the top inch of soil feels dry to the touch.

Q: Can I grow an arrowhead plant in low light?

A: While arrowhead plants prefer bright, indirect light, they can tolerate lower light conditions as well. However, growth may be slower and the color of the leaves may not be as vibrant.

Q: How do I know if my arrowhead plant has pests?

A: Look for signs such as webbing (indicating spider mites) or white fuzzy spots (indicating mealybugs). You may also notice tiny insects crawling on the leaves or stems of your plant.

In conclusion, yellowing leaves on arrowhead plants can be caused by a variety of factors including overwatering, underwatering, lack of light, and pests. By adjusting your watering schedule, increasing light exposure, and treating any pest infestations promptly, you can help keep your arrowhead plant healthy and thriving for years to come.
