Why Is My Split Leaf Philodendron Turning Yellow and How to Care for It

A yellowing Split Leaf Philodendron can be a worrying sight for any plant parent. This is often a sign that the plant is not getting enough light.

Split Leaf Philodendrons need bright, indirect light to photosynthesize and stay healthy. If your plant is not getting enough light, it may turn yellow due to a lack of chlorophyll production.

Overwatering is another common reason for a yellowing Split Leaf Philodendron. This can cause root rot, which can lead to the plant's leaves turning yellow and dropping off.

By understanding the causes of a yellowing Split Leaf Philodendron, you can take steps to care for your plant and prevent further damage.

Yellowing leaves on your split leaf philodendron can be a real concern, but don't worry, it's often a fixable issue. You'll need to become a watering ninja, striking with precision—neither too much nor too little.

Overwatering is a common mistake, and it's easy to make. Too little water, on the other hand, can also cause yellowing leaves.

Light woes can also be a culprit, so play musical chairs with your plant until it's singing in the right spot. If you've recently moved your plant to a different location, this might be the cause.

Nutrient deficiencies can also cause yellowing leaves, so whip out that fertilizer, but go easy, tiger—think 'Weakly Weekly.' This will help prevent burning your plant's roots.

If you've fertilized your plant recently, it might be over-fertilizing that's causing the problem. Feeding your indoor or outdoor plants is essential for their growth, but too much of a good thing can be bad.

To fix over-fertilizing, place your plant in the sink and flush the soil with water. Repeat this process four times to flush out the salt build-up and fertilizer.

Overwatering is a common cause of yellow leaves on split-leaf philodendrons, as it can prevent the roots from taking up nutrients and lead to root rot.

Too much water can cause the soil to become soggy, and if left unchecked, it can kill your plant. In severe cases, you may need to repot your philodendron with fresh potting mix.

To avoid overwatering, water your philodendron only when the top inch or two of soil has begun to dry out. This will help prevent waterlogged soil and root rot.

If you do overwater your philodendron, you can try to salvage it by leaving it alone and allowing excess moisture to evaporate from the soil. However, if the damage is severe, you may need to repot your plant with fresh soil and trim away any decaying roots.

Underwatering can also cause yellow leaves, especially if the plant is not receiving enough moisture. A thirsty philodendron can turn yellow, and if left untreated, the leaves may turn brown and fall off.

To determine whether your philodendron has been over- or underwatered, look for signs such as swollen and mushy leaves (overwatered) or wilted and thin leaves (underwatered).

Here's a quick guide to help you identify the issue:

By being mindful of your watering schedule and taking steps to prevent over- and underwatering, you can help keep your split-leaf philodendron healthy and thriving.

Philodendrons thrive in high-humidity environments, typically above 60 to 70 percent. Low humidity can cause yellow leaves, especially when combined with dry soil.

Grouping your philodendron with other moisture-loving plants can create a more humid microclimate. Alternatively, running a small humidifier near your plant can also help.

Too much direct sunlight can cause yellow leaf spots, which can darken with time. Moving your plant further away from direct sunlight or behind sheer curtains can help prevent this.

Misting your split-leaf philodendron's leaves once or twice a day can help if you suspect low humidity is contributing to the problem. If the leaves perk up, consider investing in a room humidifier.

Philodendrons love high humidity, usually around 60 to 70 percent. This is because they're native to high-humidity forest environments in Central and South America.

If your philodendron's leaves are dry and turning yellow, low humidity might be the culprit. You can try misting its leaves once or twice a day to perk them up.

In fact, if the leaves perk up from the added moisture, it's a good idea to invest in a room humidifier to boost the moisture level in the air. This will save you from having to mist your plant so often.

Grouping your philodendron with other moisture-loving tropical plants can also create a more humid microclimate. This is because their leaves release moisture through transpiration.

Running a small humidifier near your plant is another effective way to combat low humidity. This will help prevent brown edges and droopy leaves caused by dry conditions.

Philodendrons are understory plants that thrive in dappled light, so too much direct sunlight can cause them to turn pale or develop yellowish spots.

Move your philodendron several feet away from a sunnier south- or west-facing window to prevent this from happening. A north-facing window or an east-facing window with only a few hours of weaker morning light is perfect for these plants.

Worth a look: Yellow Light

You can also put up a sheer curtain to help filter and weaken the light, which will help your philodendron grow more vigorously.

Water your philodendron when the top inch or two of soil has dried out, rather than following a set schedule, to ensure it gets the right amount of moisture.

If your philodendron's leaves are yellowing due to too much light, don't expect them to turn green again – they'll continue to fade and eventually die.

Here's a quick guide to help you determine the right amount of light for your philodendron:

By following these tips, you can help your philodendron thrive in its ideal environment.

Pests like aphids, spider mites, mealybugs, and scale can turn your philodendron yellow by sucking moisture out of its leaves.

Inspect your plant for yellowing leaves around the edges or spots where bugs may have had a nibble.

If you suspect pests, look for nearly invisible webs spun by spider mites and mist them lightly with water to see if they're present.

To prevent infestations and eliminate minor pest problems, spray your plant with a weak mixture of white vinegar and water.

Fungal diseases can also cause yellow leaves by disrupting nutrient flows, but pests are a more common issue.

A nutrient deficiency can be caused by hard water, poor-quality soil, or neglecting to fertilize your plant.

If you have hard water, switch to filtered, bottled, or rainwater to prevent nutrient deficiencies.

Add a teaspoon of magnesium sulfate supplement (Epsom Salts) to a gallon of water to supplement your soil's magnesium content and help correct a nutrient deficiency.

Insect infestations are a common problem for indoor plants, and your Philodendron is no exception. Some well-known insects that can affect your plant are mealy bugs, spider mites, aphids, and scale.

These pests can cause yellowing leaves by sucking out the moisture from the foliage. Fungal diseases like rust, leaf spot, and powdery mildew can also disrupt nutrient flows essential for green coloration.

Inspect your plant carefully, checking the undersides of leaves for signs of pests, such as thin webbing, eggs, insect bodies, or sticky honeydew. This can help you diagnose the issue before it gets out of hand.

To treat a pest infestation, quarantine the plant from the rest of your collection and treat it with horticultural oil or insecticidal soap. You can also dab away pests with a cotton ball or swab dipped in rubbing alcohol, then wipe down leaves with a damp cloth to remove honeydew.

Mixing a gallon of water with a teaspoon of neem oil is an effective way to prevent infestations and eliminate minor pest problems naturally. This solution can be sprayed on the plant or added to the soil.

Philodendrons can be sensitive to nutrient deficiencies, which can cause yellow leaves. This is often due to a lack of iron, magnesium, or calcium in the soil.

A soil tester can help identify the problem before adding fertilizers. If the soil is lacking in magnesium, adding a teaspoon of magnesium sulfate supplement (Epsom Salts) to a gallon of water can help.

Yellow spots on the surface of foliage might indicate a magnesium deficiency. To correct this, water the plant with the magnesium solution, but avoid overwatering.

If the yellowing leaves persist, the soil may be low in iron. In this case, a store-bought fertilizer like Ironite can be used to supplement the iron.

It's essential to use a soil tester before applying any fertilizer or salts to the plant, as this can affect its pH or nutrient balance.

A nutrient deficiency can cause yellow leaves to form v-shaped patterns along the veins of the plant's leaves. Supplementing the soil's magnesium content can help correct this issue.

Over-fertilizing can also cause yellow leaves, particularly with leaf drops. To fix this, flush the soil with water and repeat the process four times to remove the salt build-up and fertilizer.

To keep your Split Leaf Philodendron happy and healthy, it's essential to understand its care and maintenance needs. You can grow it indoors or outdoors, but it prefers well-draining soil and indirect sunlight, which can be achieved by placing it near an east- or west-facing window.

To avoid root rot, make sure the pot has good drainage holes and repot your philodendron every 1-2 years in the spring when it becomes pot-bound. You can also check for root rot by looking for soft, mushy roots, which can be a sign of overwatering.

Water your philodendron when the top 1-2 inches of soil feel dry to the touch, and avoid getting water on the leaves to prevent fungal diseases. Humidity is also crucial, as Split Leaf Philodendron prefers a humid environment, typically between 50-70% relative humidity.

Here are some key care and maintenance tips for your Split Leaf Philodendron:

Split-leaf philodendrons generally prefer a peaty, soil-based potting mix. An expert we interviewed recommends mixing your own potting mix for philodendrons.

To keep your philodendron happy, provide it with a trellis or stake to climb, as its tall leaves tend to fall over or grow horizontally without support.

You'll need to repot your philodendron every year or so to avoid becoming rootbound, which they hate. If you prefer to keep your plant in the original pot size, you can propagate the philodendron cuttings you prune away and grow them in vases.

Here are some general guidelines for caring for your philodendron:

As a plant parent, it's natural to worry when you notice yellow leaves on your split-leaf philodendron. However, it's essential to remember that shedding and regrowth are a normal part of your plant's life cycle.

A plant only has so much energy to put into growth, and sustaining old, damaged leaves takes precious energy away from growing new ones. This is why your philodendron may shed leaves to make way for new growth.

If most of the yellowing leaves are near the bottom tier of foliage, it's likely that the yellowing is part of the natural growth cycle of your plant. This can be a reassuring thought, especially if your plant is otherwise thriving.

This process of shedding and regrowth is a natural part of your philodendron's life cycle, just like it is for most plants.

Philodendron leaves turning yellow is a sign that something is amiss with your plant.

Overwatering is a common reason for yellowing leaves. The Plant Expert advises against bottom-watering, as it can lead to stagnant water and root rot.

Watering from the top, letting the soil become moist but not soggy, is a better approach.

The soil should be allowed to dry slightly before watering again. This will prevent overwatering and promote healthy growth.
