What Causes Philodendron Leaves to Turn Brown?
Philodendron leaves turn brown because of several causes, including incorrect soil type, over or under-watering, and low humidity levels. You will also see brown spots if you place your plants under direct sunlight. Sometimes, pest feeding and cold stress can change the plant’s color.
– Using Incorrect Soil For Growing
When grown in unsuitable soil, issues like philodendron xanadu leaves turning brown can arise. The biggest thing that makes soil “bad” is poor drainage. If it retains excessive moisture near the roots, the chances of root rot (one of the worst fungal diseases) will go higher.
Similarly, roots can’t breathe when immersed in water. When this happens, they can’t absorb moisture (even though they are under the water). As a result, the plant gets weak and starts to become brown.
Conversely, soil that drains too swiftly might not offer the roots enough time to absorb the necessary moisture, leading to dehydration and browning of the leaves. So, when you water, carefully examine whether the soil retains too much moisture or gets dry quickly.
– Not Enough Water
A common query among plant enthusiasts is, “Why is my philodendron turning yellow and brown?” The answer often lies in the watering routine. Underwatering can lead to yellow leaves because water is a critical part of processes like evaporation. Such processes keep the internal temperature within optimal range, which keeps the plant healthy.
So, when you don’t add enough water, the internal processes can stop, leading to yellowing. If not addressed, the yellow patches can become brown. So, if you are witnessing “philodendron leaves turning yellow and brown,” and the top two inches of soil feel bone dry, the reason behind the discoloration is underwatering.
– Dry Air (Less Humidity Levels)
Originating from tropical regions, philodendrons have a natural affinity for humid environments. That’s why these plants exhibit signs of stress when exposed to dry air, particularly for extended periods. One of the most common symptoms is the Philodendron new leaves turning brown.
Dry air can cause rapid moisture loss from the plant, leading to dehydration. This is especially concerning for indoor plants that might be situated near heaters or in rooms with low ambient humidity.
– Diseases: Another Leading Cause
Diseases can wreak havoc on philodendrons, leading to many symptoms, including browning leaves. One prevalent issue is the fungal leaf spot disease, which manifests as Philodendron leaves brown spots.
If not addressed promptly, these spots can enlarge. With time, you’ll notice Philodendron leaves turning black. Another significant concern is root rot, which we’ve discussed earlier. Moreover, Bacterial leaf spots are another ailment that can cause browning. In this, you’ll also observe Philodendron leaves curling.
You can confirm a disease attack by checking the soil condition. If it looks bad and discolored, fungus or bacteria have attacked. You might also smell a foul odor from the root zone. Spots on leaves are another indication of infection.
– Placing Plants Directly Under the Sun
Philodendrons love light, but not too much of it. When they’re placed directly under the sun, they can get sunburned. This sunburn often shows up as brown leaf tips on the plant. The effect will be visible on the top leaves first. With time, every leaf will become brown if you don’t do anything.
– Cold Stress: The Winter Damage
Philodendrons are tropical plants that are used in warm, humid environments. So, when they’re exposed to cold temperatures, they can get stressed. This stress often shows up as Philodendron leaves brown edges. It’s their way of telling you they’re unhappy with the cold.
– Giving More Fertilizers than Recommended
Fertilizers provide essential nutrients that help plants (including Philodendron) grow strong and healthy. However, as taking too many vitamins can harm humans, over-fertilizing can harm your philodendron plant.
When given in excess, fertilizers can lead to a buildup of salts in the soil. These salts can draw moisture from the plant’s roots, causing dehydration. The first signs of this are often brown tips on the leaves. As the condition worsens, entire brown leaves can appear. It indicates that the plant is receiving more nutrients than it can handle.
– Pest Feeding
Pests are a nightmare for any plant owner. For philodendrons, certain pests can be particularly troublesome. These pests feed on the plant’s sap, depriving it of essential nutrients. Over time, this feeding can lead to visible damage.
One of the first signs of pest infestations is the Philodendron leaves turning brown and brown. The leaves might start curling as the pests feed, indicating severe stress.
Regularly inspecting your Philodendron for pests and checking the leaves top and bottom can help in early detection. But there’s a lot more to do if you want your Philodendron to stay healthy, which is what we’re now discussing.
How to Fix the Brown Leaves of a Philodendron Plant
– Change the Soil if It’s Wrong or Gone Bad
Over time, soil can become compacted, lose nutrients, or even become contaminated. If you think the soil isn’t good, it might be time to change it. Remember that fresh, well-draining soil can make a world of difference.
But when changing the soil, ensure you gently remove the old soil from the roots, not damaging them. Then, repot the Philodendron in a pot with adequate drainage holes. It will provide a new start, and the leaves will become healthy again.
– Learn About the Watering Requirements of Philodendrons
Philodendrons have specific watering needs. To keep them vibrant and prevent brown spots, it’s essential to water philodendron plants correctly. Note that these plants prefer their soil to be kept evenly moist but not soggy.
Ensure you water thoroughly when watering, allowing the water to drain from the pot’s bottom. This ensures the roots get adequately hydrated. You can also use the ice cube method to water these plants. You place two to three ice cubes on the soil and let them melt. This slowly adds moisture to the soil, so you won’t have to worry about overwatering.
– Maintain Humidity Levels Around 60 Percent
Philodendrons, with their tropical origins, thrive in environments with higher humidity. Aiming for a humidity level of around 60 percent can significantly affect their health and appearance. But did you know that different philodendrons might have slightly varied humidity needs?
- Heartleaf Philodendron: This popular houseplant, with its heart-shaped leaves, prefers humidity levels between 60 to 70 percent. It’s a forgiving plant, but its leaves might brown at the edges if the air gets too dry.
- Thaumatophyllum Xanadu: Previously known as Philodendron Xanadu, this plant loves humidity. It thrives best when humidity levels are maintained between 65 to 75 percent. In drier conditions, its leaves can become crispy.
- Philodendron Erubescens: This plant has striking red stems, also known as the Red Emerald Philodendron. It enjoys humidity levels of around 60 to 70 percent. When the air is too dry, its growth can become stunted, and its vibrant color might fade.
- Philodendron Cordatum: This heart-leafed beauty is adaptable but prefers humidity levels between 55 to 65 percent. Its growth might slow in lower humidity, and its leaves can develop brown tips.
Consider using a room humidifier to maintain these humidity levels, especially during drier months. Alternatively, placing the plant on a tray filled with water and pebbles can also help increase the surrounding humidity.
– Fertilize in the Correct Manner
Fertilizing is like giving your Philodendron a nutrient boost. However, it’s essential to do it right. Over-fertilizing or using the wrong fertilizer can lead to philodendron brown spots on the leaves. Here’s what you need to know:
- Philodendrons aren’t heavy feeders. They typically require a balanced, water-soluble fertilizer. When feeding your plant, following the recommended dosage on the fertilizer package is crucial. Overdoing it can lead to a buildup of salts in the soil, leading to brown Philodendron.
- It’s also a good practice to water your Philodendron before fertilizing. This ensures the roots are moist and can absorb the nutrients more effectively. Fertilizing a dry plant can lead to root burn.
- Remember, your Philodendron’s growth will slow during the dormant winter months. It’s best to reduce the frequency of fertilization during this period.
By understanding your Philodendron’s specific needs and adjusting your care routine, you can ensure a lush, vibrant plant that’s a joy to behold.
– Provide Protection from Environmental Extremes
