Yellow leaves on a split-leaf philodendron can be a common issue for plant enthusiasts. There are several reasons why your plant may be experiencing leaf discolouration, and understanding these causes is essential for effective remediation. Let’s explore the underlying factors and solutions in the article below.

1 Understanding the Causes of Yellow Leaves on Your Split-Leaf Philodendron

Causes of Yellow Leaves on Split-Leaf Philodendrons

Several factors can contribute to the yellowing of leaves on your split-leaf philodendron, but the following are the most common reasons:

Overwatering: Excessive watering leads to soil conditions that are no longer suitable for the plant’s growth.
Underwatering: Dry soil that doesn’t provide enough moisture to the plant will result in brown edges on the leaves, eventually turning them entirely yellow.
Inappropriate Lighting: Split-leaf philodendrons thrive in areas with indirect sunlight. Placing the plant in direct sunlight will scorch the leaves, making them crisp and turning them brown or yellow.
Insect Infestation: Spider mites, scale insects, and mealybugs can suck moisture from the plant, causing leaf discolouration. If left untreated, the plant will become weakened and unable to recover.
Natural Growth Process: If your split-leaf philodendron is producing new leaves and the oldest leaves at the bottom of the plant are turning yellow, it’s a natural occurrence. Your plant is shedding old leaves to focus its energy on new growth.

2 Remedies for Yellow Leaves on Your Split-Leaf Philodendron

Remedies for Yellow Leaves

If your split-leaf philodendron is suffering from yellow leaves due to overwatering, try the following corrective measures:

Water your plant only when the top layer of soil is dry. Maintain moist but not soggy growing media.
Ensure you water slowly and thoroughly, providing adequate water to the plant. During colder seasons or periods of high humidity, extend the time between waterings.
If your plant is showing signs of leaf discolouration due to underwatering, increase humidity by misting the leaves or using a humidifier.
If leaves are scorched and yellow due to direct sunlight, relocate your split-leaf philodendron to a position with suitable lighting – not too strong or too weak. Insufficient light will also cause leaf discolouration.
To address insect infestations, mix soap with water at a ratio of 1:10 and spray it evenly on the leaves and stems. Repeat this process every 3-5 days until the insects and their eggs are eliminated.
Use the soap and water mixture to combat insect infestations and restore the health of your split-leaf philodendron.
If, despite your efforts, the leaves remain yellow, remove them to prevent the plant from wasting energy on damaged leaves. This will allow your plant to redirect its energy towards healthy growth.

We hope that the information provided on the causes and solutions for yellow leaves on your split-leaf philodendron will help you nurture a healthy and vibrant plant.

Frequently asked questions

There are several reasons why the leaves of your Split-leaf Philodendron (Monstera deliciosa) may be turning yellow. It could be due to overwatering, nutrient deficiencies, excessive sunlight, or natural aging. It is important to identify the specific cause to take appropriate corrective actions.

Overwatering is a common issue with Split-leaf Philodendrons. Symptoms include yellowing leaves, especially if they are soft and mushy, and root rot. Allow the soil to dry out slightly between waterings and ensure proper drainage to prevent overwatering.

Nitrogen, magnesium, and iron deficiencies are commonly associated with yellow leaves in Philodendrons. A nitrogen deficiency will cause older leaves to turn yellow first, while a magnesium or iron deficiency will result in yellowing between the leaf veins.

These plants thrive in bright, indirect sunlight. Direct sunlight can scorch the leaves, causing them to turn yellow or brown. If your plant is receiving too much direct sunlight, move it to a location with bright, filtered light.

Yes, it is natural for the older leaves of a Split-leaf Philodendron to turn yellow and eventually fall off as the plant grows and directs its energy towards new growth. This is particularly common with lower leaves. Ensure you provide adequate care to promote healthy new growth.
