Why are my philodendron leaves turning yellow? Here Are The Most Common Causes

You were enjoying your philodendron houseplant for a while. Still, suddenly you find that your philodendron leaves are turning yellow, and you are wondering why are my philodendron leaves turning yellow?

There are many reasons why leaves on philodendrons might turn yellow. Some causes are environmental factors, such as over-watering or not providing enough light. Other causes may be more specific to the plant itself, such as damage from a pest or disease. If you suspect that your philodendron is experiencing any of these problems, you’ll need to take action to correct them.

This article will cover the most common causes of yellow leaves on philodendron plants and offer some solutions.

Why are philodendron leaves turning yellow?

The most common cause of yellowing or wilting philodendron leaves is a deficiency in the plant’s nutrients. Philodendron leaves may also turn yellow due to damage by pests, such as aphids or whiteflies. If the plant is not getting enough sunlight, its leaves may also turn yellow.

We will explain some of the most common causes of leaf yellowing and how to treat them.

Nutrient deficiency

One common problem with philodendrons is nutrient deficiency, which can cause leaves to turn yellow and become brittle. Deficiencies can occur when the plant doesn’t receive enough nitrogen, potassium, or phosphorus. A soil test can help identify specific weaknesses in your philodendron’s environment.

Root rot causes

Root rot is a fungus that attacks the root system of plants. The fungus enters the plant through the soil and spreads down to the roots, where it causes them to die. This can happen to any plant, but it is most common in philodendrons. The leaves will turn yellow and fall off, eventually leaving the plant to die. There is no cure for root rot, so prevention is key. Ensure your plants are well-watered and fertilized, and keep away from diseased plants. If you find your philodendron has root rot, there’s not much you can do other than remove the affected plants from your garden.

Pest infestation

The leaves of a philodendron may turn yellow and fall off due to infestation by pests. The most common pests are aphids, which suck the sap from the leaves, and mites burrow into the leaves. These pests can cause the leaves to turn yellow and fall off. If you notice your philodendron has yellow leaves, and some are falling off, there is a good chance it is infected with one or more pests. There is no cure for philodendron pests, so you will need to take action to get rid of them. Use a spray to kill the aphids and mites and treat the soil around the plants with an insecticide.

Overwatering or underwatering 

Watering philodendron plants can be a challenge. Too much water and the leaves can turn yellow and die. Too little water, and the roots may rot. Philodendrons are particularly sensitive to overwatering because they have large root systems that need plenty of moisture to grow well. It is essential to check the plant frequently to adjust watering as needed.

Natural yellowing and shedding 

The leaves will eventually fall off the plant and decay. This natural process is called shedding. Shifting soil can also cause leaves to turn yellow and lose wat. Philodendron leaves turn yellow and fall off because of a natural process called yellowing and shedding. Yellowing is the gradual loss of green color in the leaves, while shedding is when the leaves fall off the stem. Yellowing and shedding can be caused by several things, including sun exposure, lack of water, pests, and diseases. Suppose you’re seeing yellowing and shedding on your philodendron. In that case, the best action is to check the plant’s environment and take any necessary steps to address the problem.

Temperature fluctuations 

Temperature fluctuations can play a significant role in turning yellow leaves on philodendrons. When temperatures are high, the leaves will convert more of their photosynthesis into creating chlorophyll. This will cause the leaves to become yellower and eventually turn yellow. Conversely, when temperatures are low, the leaves will convert less photosynthesis into creating chlorophyll, resulting in a green appearance and eventual lack of yellowing.

Low humidity

Low humidity levels are the most common reason why philodendron leaves turn yellow. When the air is too dry, the leaves become brittle and can easily break. Additionally, the leaves will take on a yellow color as they lose their chlorophyll. Suppose your plant is experiencing low humidity levels. In that case, you can try to increase the humidity by misting or spraying the leaves.

Poor soil nutrition

Poor soil nutrition is one of the most common reasons for leaves on philodendron turning yellow. A lack of nitrogen, phosphorus, and potassium can lead to yellowing and stunting of the plants’ growth. These elements are essential for plant growth and function. You can increase the plant’s nutrient uptake by adding a layer of compost or organic matter to the soil or by fertilizing with a balanced fertilizer.

Fungal diseases 

A few fungal diseases can cause leaves on philodendrons to turn yellow and eventually die. One of the most common is Botrytis cinerea, caused by a fungus. The fungus grows on the surface of the leaves, making them dry out and fall off. This condition is referred to as leaf dieback or botrytis disease.

Other fungal diseases that can cause leaf death in philodendrons include:

• Phytophthora cinnamomi (soil-borne fungi).
• Alternaria solani (a plant pathogen).
• Sphaerotheca macularis (a soil-borne fungus).

Each of these fungi causes specific symptoms that must be identified and treated accordingly. Philodendron owners should always consult with a professional if they notice their plants are showing signs of a fungal disease.

Seasonal Changes Causes philodendron leaves turning yellow

When it comes to the leaves on your philodendron, they are going through many changes during the seasons. In the Springtime, the leaves will start to grow and turn green. As the days get warmer, the leaves will change colors, from yellow and green to reddish-brown. The Summertime is when the leaves start to grow and get big. They will be a different color every day, but they will usually be bright green or yellow. The Fall is when all of the leaves on your philodendron will fall off and die. At this point, your philodendron might have new growth starting in late November or early December.

Plant Leaves Turning Yellow With Age

Philodendrons are beautiful plants that can add a splash of color to any room. However, if the leaves on your philodendron start to turn yellow and fall off, it is likely due to age or neglect. Over time, the leaves will lose their ability to photosynthesize and will become dry and brittle. If the plant is not given enough water and sunlight, the leaves will eventually fall off. Suppose you notice that your philodendron’s leaves turn yellow and fall off. In that case, it is essential to take steps to care for it properly. Give it plenty of water and sunlight, prune back any overgrown foliage, and make sure there is enough humidity in the air. By taking these simple steps, you can help your philodendron stay healthy and vibrant for years to come.

How to fix philodendron leaves turning yellow

Many factors can cause leaves on a philodendron to turn yellow. The most common causes are environmental stress, lack of light, and improper watering habits. Here are some tips for fixing yellow leaves on your philodendron:

• Check the environment for possible sources of environmental stress. This could include a lack of sunlight or water availability. If the plant is in an area with high humidity, it may also be experiencing environmental stress.
• Give your philodendron enough light and water to ensure proper growth and health. Over-watering can result in wilting or even death of the leaves, while under-watering can cause leaves to become dry and brittle. Philodendrons need approximately 1/2 inch of water per week, so check the soil moisture level and adjust.
• Prune back any overgrown foliage. Overgrowth can block light and water from reaching the leaves, contributing to yellowing and eventual leaf drop.
• Humidity is essential for healthy philodendron growth and leaf health. Mist or spray your plant regularly with a humidifier or distilled water to maintain high humidity levels in the air around it. 
• Feed your philodendron a balanced mix of fertilizers during the growing season. Choose a fertilizer designed explicitly for philodendrons and use the recommended dosage.
• Remove any dead leaves and branches. Over time, dead leaves and stems can accumulate on the plant, contributing to yellowing and leaf drops.

FAQ about Why are philodendron leaves turning yellow

Why is my philodendron Birkin turning yellow?

The plant’s leaves may be yellowing due to a lack of sunlight. Without an adequate amount of light, the plant will not be able to produce the chlorophyll necessary for photosynthesis. As a result, the leaves will turn yellow. Additionally, if the plant is not getting enough water, its leaves may also turn yellow.

Should I remove yellow leaves from philodendron?

The leaves of a philodendron plant can be either green or yellow. If the leaves are mostly yellow, it might be time to prune the plant. Pruning a philodendron can help keep it healthy and looking good. Removing the yellow leaves will allow the new, green leaves to grow.

Can Yellow philodendron leaves turn green again?

The leaves of a yellow philodendron can turn green again if the plant is getting enough sunlight. The leaves will turn green again as the plant begins to photosynthesize and produce energy. The leaves may also turn green if the plant is over-watered or not getting enough nitrogen.

How often should you water a philodendron?

The most important thing to remember when watering philodendrons is that they should always be given a thorough drenching. Do not water them sparingly or allow the water to sit on the leaves; instead, make sure the entire pot is wetted down. Philodendrons are opportunistic water consumers and quickly turn yellow and die if they don’t receive enough moisture.

How do I know if my philodendron is healthy?
