Why are the leaves on my Philodendron turning yellow?

The leaves on your Philodendron could be turning yellow for a number of reasons. Let’s investigate and get to the bottom of this!


The most common cause of yellowing leaves among Philodendron plants is improper soil moisture–in particular, overwatering. Only water your Philodendron when the top 25% of the soil in the pot is dry. Soil should remain damp, but not wet. In the winter, you can allow your plant to dry out a little more between waterings, but be sure to boost humidity with regular misting, a humidifier, or pebble tray.


When you water your Philodendron, make sure you provide enough water so that liquid flows from the drainage hole at the bottom of the pot and into the saucer. It’s extremely important to discard any excess water in the saucer and to not let your plant sit in standing water. Your Philodendron will not respond well to “wet feet,” which causes the roots to rot and the eventual death of the plant.


Providing proper and consistent soil moisture is important in caring for a Philodendron. Alternating between bone dry and wet soil from ill-timed waterings can create stress and cause your Philodendron to yellow. 


Your humidity level

Low humidity and dry soil cause leaves to droop and brown on their edges, later followed by entire yellowing. Misting the leaves of your Philodendron often will increase the humidity. 


Improper Light

Philodendrons will grow best when placed in bright indirect sunlight. When exposed to direct sunlight for too long, the foliage will burn. While Philodendrons can adapt to low light areas, their growth will slow. If placed in very low light, yellow leaves may develop.



A weakened or stressed Philodendron is more susceptible to insect infestations. Sap-sucking bugs like spider mites can drain your plant of moisture. This problem quickly manifests itself by yellowing leaflets and fronds. Scale, mealybugs, and spider mites occur frequently in indoor conditions. If not killed early on, these small pests proliferate and move all along frond parts into nooks and crannies. The piercing mouths of the insects exhaust your plant and accelerate yellowing, especially if your Philodendron is already unhealthy from poor lighting, a nutrient deficiency or improper soil moisture. 


Some yellowing is natural

Is your Philodendron pushing out new growth? If there is new growth on your plant and the yellowing leaves are older, particularly at the bottom of the plant, this yellowing is natural. Your plant sheds its old leaves and sends energy to new growth.
