Why Are My Philodendron's Leaves Turning Yellow?
Philodendrons are charming and vibrant, often with variegated foliage that grows in gorgeous cascades, and they're a beloved low-maintenance houseplant. But even with their easy-going temperament, they can develop yellowing foliage, which can be troubling. Here's why your Philodendron's leaves may be turning yellow and how to get it back on track.
At Léon & George, our master gardeners have spent nearly a decade growing premium plants and helping thousands of plant parents nationwide, so the guidance here comes straight from hands-on experience.
Natural Aging
Most plants shed some yellowing foliage from time to time as they drop old growth to focus on new leaves, and occasionally a young leaf just doesn't thrive. This isn't a systemic health issue, just normal plant behavior. If your Philodendron looks healthy overall but has a few yellow leaves, simply pull them off gently or trim them with clean, sharp scissors.
Overwatering
Philodendrons can be overwatered, and yellowing foliage is one of the most common signs. Water only when the top two inches of soil are dry to the touch, rather than on a timetable. Check by lifting the decorative moss and inserting your finger two inches into the soil; if it's dry, water, and if it's still moist, hold off. Persistently soggy soil leads to widespread yellowing and, eventually, root rot.
Incorrect Light
Too little light, or harsh direct sun, can also cause yellowing. Philodendrons are happiest in bright, indirect light. If yours sits in deep shade or direct sun, adjust its position. Once watering and light are dialed in, new leaves will come in a healthy, vibrant green.
Frequently Asked Questions
Why is my Philodendron turning yellow?
A few yellow leaves is usually natural aging. Widespread yellowing is most often overwatering, and incorrect light (too little or too much) can also be a cause. Check the soil moisture first.
How often should I water a Philodendron?
Only when the top two inches of soil are dry, typically every seven to ten days. Always check the soil rather than watering on a fixed schedule, as overwatering is the main cause of yellowing.
Should I cut yellow leaves off my Philodendron?
Yes. Yellow leaves won't turn green again, so pluck or trim them with clean scissors to let the plant focus its energy on healthy new growth.
How much light does a Philodendron need?
Bright, indirect light is ideal. Too little light or harsh direct sun can both cause yellowing, so place your Philodendron near a window but out of direct rays.
