Philodendron Leaves Turning Yellow: Causes and Solutions

Finding your Philodendron with yellowing leaves can be frustrating. You may wonder what you’re doing wrong. Don’t worry, most of the issues causing yellowing leaves can be fixed if you act quickly.

Why Are My Philodendron Leaves Turning Yellow? 

There are many reasons for a Philodendron’s leaves turning yellow. Knowing the cause will help resolve the situation quickly. Here are some of the most common reasons:

• Overwatering
• Insufficient light
• Lack of nutrients
• Natural aging process
• Excessive fertilizing
• Pests

How Do You Fix Yellow Leaves on Philodendron?

Check your plant’s soil, and if it’s wet, refrain from watering until the top inches are dry. If the plant is seriously affected, you may need to repot it in fresh, well-draining soil and remove roots affected by root rot.

If your Philodendron plant isn’t getting enough light, move it closer to a window. Philodendron plants should be protected from direct sunlight, which can scorch their leaves.  

Be careful when fertilizing; use a balanced fertilizer to provide all the necessary nutrients, and always dilute the recommended dose to avoid overfertilizing. Repot every few years into fresh, nutrient-rich soil.

If one or two leaves turn yellow only occasionally, it’s probably part of the plant’s natural aging process. Check your plant regularly for insects and treat with organic insecticide if necessary.

Other Common Philodendron Problems

While they’re easy-care plants, Philodendrons need the right growing conditions to grow well indoors. They may struggle if grown in an unsuitable location or not given proper care. So, what are some common problems with Philodendron?

What Causes Philodendron Leaves to Curl? 

Philodendron leaves may curl as part of the plant’s defensive mechanism, reacting to temperature fluctuations or insufficient watering. Houseplants also sometimes suffer due to low humidity in dry indoor spaces.

Philodendron Leaves Curling: Fixes

Check the plant’s soil and water if necessary. Place your Philodendron’s pot on a pebble tray to trap moisture, group with other plants to increase humidity, or use a humidifier. Keep your plant away from doors or windows, as cold drafts can stress the plant.

Why Are the Leaves on My Philodendron Turning Brown? 

Wondering why your Philodendron leaves are turning brown? Here are some of the most likely causes of Philodendron leaves turning brown:

• Underwatering
• Low humidity  
• Fungal or bacterial issues (usually large brown spots on the leaves)
• Sunburn

How to Get Rid of Brown Spots on Philodendron Leaves?

The first thing to do if your Philodendron has brown leaves is to check the soil. It may simply be underwatered.

Increase the humidity using a pebble tray or a humidifier. Brown or yellow spots on Philodendron leaves, especially if they’re spreading, can be a sign of fungal or bacterial disease. Fungal spots will normally have a brown or black ring around them, while bacterial spots are often mushy and discolored. Move an affected plant away from other plants, and treat it with the appropriate fungicide.

If you find tiny brown spots, evenly distributed on the leaf, they’re likely nectaries, a natural, sap-producing part of the Philodendron’s leaves.

Crisp, brown spots near the edges are often scorch marks from overexposure to direct sunlight. Move your plant away from the window.

Philodendron Drooping Leaves: Reasons and Fixes 

Philodendron leaves drooping can be caused by low temperatures, transplant shock, inconsistent watering, or low light. If you notice your Philodendron leaves turning mushy, the reason is overwatering.

How Do You Fix a Droopy Philodendron?

Check the soil to make sure it isn’t soggy (you can use a moisture meter), and move your plant closer to the window if it’s not getting enough light. Keep it away from cold drafts or heat vents. If it’s suffering from transplant shock, give it time to recover.

Why Are Leaves Falling Off My Philodendron?

A Philodendron dropping leaves is often a sign of watering issues. Check the soil and watch for other signs of overwatering or insufficient watering. Inappropriate lighting or shock from sudden heat or cold can also cause leaf drop.

Will Philodendron Leaves Grow Back?

Philodendron leaves won’t grow back on the exact spot, but new leaves will normally bud from the top of the stem. If moved to more favorable conditions, the Philodendron plant will recover and continue growing.
