Many arrowhead plant owners have encountered this issue at some point in their gardening journey. So why exactly do these vibrant plants start to turn yellow, and more importantly, how can you fix it? Let’s find out!
Arrowhead plants, also known as Syngonium podophyllum, are popular houseplants known for their attractive, arrow-shaped foliage. However, it’s common to notice the leaves turning yellow, which can be worrying. In this article, we’ll explore the possible causes and solutions for yellowing arrowhead plant leaves to get your plant back to good health.
What Causes Arrowhead Plant Leaves to Turn Yellow?
There are a few key reasons why the leaves on your arrowhead plant may start to yellow.
Improper Watering
Excessive watering can lead to saturated soil, resulting in root rot and yellowing leaves. On the flip side inadequate watering causes the leaves to dry out and yellow as well. Avoid both extremes by watering only when the top 1-2 inches of soil become dry.
Low Humidity
Arrowhead plants prefer a humid environment. Low humidity causes the leaves to brown and yellow along the edges. Boost humidity through regular misting, using a humidifier, or placing your plant on a pebble tray.
Insufficient Light
Arrowhead plants need bright, indirect light Too much shade leads to weak, yellowing leaves Move your plant to a brighter location, but avoid direct sun which can scorch the leaves.
Temperature Stress
Drastic temperature changes or cold drafts shock arrowhead plants causing yellowing leaves. Keep your plant away from air vents, windows, and doors. Maintain a temperature between 60-80°F.
Nutrient Deficiencies
Lack of nutrients like nitrogen, iron, and magnesium shows up as yellowing leaves. Apply a balanced liquid fertilizer every 2-4 weeks during the growing season.
Pests
Spider mites, mealybugs, and other pests feed on and damage leaves, causing yellow spots. Treat infestations immediately by isolation, pruning affected parts, using insecticidal soap, and removing heavily infested plants.
Diseases
Fungal diseases like root rot, powdery mildew, and botrytis blight can contribute to yellowing leaves. Improve airflow and isolate affected plants. Remove and destroy severely infected plants.
Natural Causes
As part of the natural growth cycle, lower mature leaves will yellow and drop off over time. This is normal as long as it’s only affecting the oldest leaves.
How to Fix and Prevent Yellow Leaves on Your Arrowhead Plant
Once you’ve diagnosed the cause of the yellowing leaves, here are some tips to get your arrowhead plant healthy again:
-
Adjust watering frequency – Water only when the top inch of soil is dry to prevent overwatering. Or increase watering if leaves are dry and crispy.
-
Increase humidity – Use a humidifier, place on a pebble tray, or mist leaves daily to combat low humidity.
-
Provide adequate sunlight – Place in a brighter location with indirect sun to prevent insufficient light. Filter harsh sun with curtains.
-
Maintain ideal temperature – Keep between 60-80°F and away from cold drafts.
-
Apply fertilizer – Use a balanced liquid fertilizer every 2-4 weeks in the growing season.
-
Treat pests – Isolate and prune affected parts. Use insecticidal soap sprays to treat infestations.
-
Improve airflow – Circulate air with fans and prune congested growth to prevent diseases.
-
Repot annually – Repot in fresh, well-draining soil to replenish nutrients.
-
Prune regularly – Remove yellow or dead leaves and stems to encourage new growth.
With the proper care, your arrowhead plant’s yellow leaves can recover. Be vigilant about monitoring for pests, diseases, and environmental issues to keep your plant happy and healthy. With the right growing conditions and care, you can enjoy the vibrant green arrow-shaped leaves that this tropical plant is prized for.
Lack of Humidity
Another possible reason for yellowing leaves could be a lack of humidity in the air. Arrowhead plants are native to tropical regions where they thrive in high humidity environments. When grown indoors, however, the dry air can cause their leaves to lose moisture and turn yellow. A lack of humidity makes it difficult for the plants to retain adequate moisture through their leaves, leading to dehydration and stress, resulting in yellowing foliage.
To remedy this issue, try increasing the humidity around your arrowhead plant. You can do this by placing a humidifier near the plant or creating a humidity tray filled with water next to or underneath its pot. Just don’t let the pot sit in the water as this could lead to waterlogged soil. Grouping several houseplants together can also help create a microclimate of higher humidity.
Poor Light Conditions
As they are tropical, Arrowhead plants thrive in bright, indirect light, and if they are not receiving enough light, their leaves can turn yellow. If your arrowhead plant is placed in a dark corner or far away from a window, it may not be getting sufficient sunlight. Lack of natural light can hinder the plant’s ability to photosynthesize and produce energy, which can manifest as yellowing leaves.
To fix this issue, try moving your arrowhead plant to a brighter location with indirect sunlight. Avoid placing it in direct sunlight as this can scorch its delicate foliage. If you notice that the yellowing only occurs on one side of the plant, rotate it regularly to ensure all parts receive equal exposure to light.
In some cases, artificial lighting such as fluorescent lights or grow lights can also provide adequate illumination for Arrowhead plants. Consider supplementing natural light with these artificial sources if necessary.
One of the possible reasons why your arrowhead plant is developing yellow leaves is due to temperature changes. Sudden drops or increases in temperature can cause stress to the plant, leading to leaf discoloration, and it’s important to fix the issue before the plant gets too stressed.
During colder months, ensure that your Arrowhead plant is not exposed to drafts or cold air from windows or doors. This sudden change in temperature can shock the plant and result in yellowing leaves. Similarly, excessive heat can also have a negative impact on your arrowhead plant. Placing it near heating vents or radiators can dry out the foliage and cause it to turn yellow.
To prevent temperature-related leaf issues, try maintaining a consistent room temperature for your arrowhead plant. Avoid placing it near any extreme sources of heat or cold drafts. You could also use a thermometer near the plant to keep a closer eye on the temperature directly around your plant.
Nutrient deficiencies can be a common cause of yellow leaves in Arrowhead plants, as well. These tropical beauties require a well-balanced diet to thrive and maintain their lush green foliage, and when essential nutrients are lacking, the plant may show signs of distress. You’ll know it’s a nutrient deficiency if your plant just seems to look kind of dull and you’ve ruled out any other possible causes of the yellowing leaves.
To rectify nutrient deficiencies, fertilize your Arrowhead plant regularly. It’s suggested to use a plant food that is given with each watering to ensure your plant has a steady supply of nutrients at all times. Also, monitor the soil pH level as some nutrients may become less available if the pH is too high or low. Aim for between a 5.5-6.5 pH level.
A pest infestation is not something that any plant parent wants to see, and unfortunately, it’s one of the most common causes of yellowing leaves. These tiny intruders can wreak havoc on your plant, causing it to become weak and unhealthy.
Common pests that may attack your arrowhead plant include spider mites, aphids, and mealybugs. These insects feed on the sap of the leaves, which can lead to discoloration and wilting.
To identify if your plant has been invaded by pests, carefully examine the undersides of the leaves for webbing or small crawling insects. You may also notice sticky residue or tiny bite marks on the foliage.
If you discover an infestation, take immediate action to eradicate these pests. Start by isolating the affected plant to prevent further spread. Depending on the severity of the infestation, you can use organic insecticidal soap or neem oil spray as natural remedies.
Arrowhead plants shed older leaves as they grow and produce new ones. These spent leaves turn yellow or brown before falling off naturally. It’s similar to how trees lose their leaves in the fall. So if you notice only a few yellow leaves here and there, don’t fret! It’s just your arrowhead plant making room for fresh growth.
However, if you’re seeing an excessive amount of yellowing or browning leaves all at once, it could be a sign of other issues such as the ones mentioned above, so go through all of the possibilities before deciding that the yellowing leaves on your Arrowhead plant are just old, spent leaves.
