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

Arboricola plants, also known as umbrella trees, are highly popular for their beautiful foliage and adaptability to different types of environments. However, if you notice that the leaves of your arboricola plant are turning yellow, it could be an indication of some underlying issues that need to be addressed.

In this article, we will explore the common causes of yellowing leaves on arboricola plants and suggest some solutions to help you restore the health and beauty of your plant.

Common Causes of Yellowing Leaves on Arboricola Plants

Overwatering

Overwatering is one of the most common causes of yellowing leaves in arboricola plants. When the roots of the plant are constantly soaked in water, they become waterlogged, which can prevent them from absorbing essential nutrients and oxygen. As a result, the leaves start to turn yellow, wilt, and drop off.

To avoid overwatering your arboricola plant, make sure to water it only when the top inch of soil is dry to the touch. Also, ensure that your pot has proper drainage holes at the bottom to allow excess water to drain out.

Underwatering

Underwatering can also cause yellowing leaves in arboricola plants. When the plant does not receive enough water, it tries to conserve moisture by shedding its leaves. As a result, the remaining leaves turn yellow and start to drop off.

To prevent underwatering your arboricola plant, make sure to water it thoroughly whenever the top inch of soil feels dry. Also, avoid leaving your plant in direct sunlight or near heat sources as it can quickly dry out the soil.

Nutrient Deficiency

Arboricola plants require a balanced supply of essential nutrients such as nitrogen, phosphorus, and potassium to grow healthy foliage. A lack of these nutrients can cause yellowing and stunted growth in leaves.

To address nutrient deficiency in your arboricola plant, consider using a slow-release fertilizer that provides a steady supply of nutrients over time. Make sure to follow the instructions on the fertilizer package and avoid over-fertilizing as it can cause root burn.

Pests and Diseases

Pests and diseases can also cause yellowing leaves in arboricola plants. Common pests such as spider mites or mealybugs can suck the sap from the leaves, causing them to turn yellow or brown. Fungal diseases such as root rot or leaf spot can also cause yellowing and wilting of leaves.

To prevent pests and diseases from affecting your arboricola plant, make sure to keep it clean and free from debris. Also, avoid overcrowding your plant with other foliage plants that can harbor pests or spread diseases.

Solutions for Yellowing Leaves on Arboricola Plants

Water Management

If you suspect that overwatering or underwatering is causing yellowing leaves in your arboricola plant, adjust your watering schedule accordingly. Make sure to water your plant regularly but avoid saturating the soil with water.

You may also want to consider repotting your plant into a well-draining potting mix or adding perlite to improve drainage.

Nutrient Supplementation

If nutrient deficiency is causing yellowing leaves in your arboricola plant, consider supplementing it with a balanced fertilizer designed for houseplants. You can choose between liquid or granular fertilizers depending on your preference.

Make sure to follow the instructions on the fertilizer package and apply it only during the growing season when your plant is actively growing.

Pest Control

If pests or diseases are causing yellowing leaves in your arboricola plant, you may need to take more aggressive measures such as using insecticides or fungicides. However, before using any chemicals on your plant, make sure to identify the type of pest or disease affecting it and choose an appropriate treatment option.

You may also want to consider using natural pest control methods such as neem oil or insecticidal soap that are less harmful to beneficial insects and safer for indoor use.

FAQ

Q: Can I save my arboricola plant if all its leaves have turned yellow?

A: Yes, you can save your arboricola plant even if all its leaves have turned yellow. Cut back all the dead stems and branches and repot it into fresh soil with proper drainage. Water it sparingly until new growth appears.

Q: Can low humidity cause yellowing leaves in arboricola plants?

A: Yes, low humidity can cause yellowing leaves in arboricola plants. These plants prefer high humidity levels between 40% – 60%. You can increase humidity by placing a humidifier near your plant or by misting its foliage regularly with water.

Q: Can pruning help prevent yellowing leaves in arboricola plants?

A: Yes, pruning can help prevent yellowing leaves in arboricola plants by removing dead or diseased foliage that can attract pests or spread diseases. You can also shape your plant by pruning back leggy stems or branches that are not producing new growth.
