The Q&A Archives: Philodendrons Have Yellow Leaves

Question: I have some philodendrons that are doing fine and others next to them that have yellow leaves and light green leaves. What is causing this and what can I do to fix the problem?

Answer: Usually this is a sign of a root problem. If a plant gets too dry it can soon develop yellow leaves. Also, if a plant stays too wet for a time, roots will be lost due to lack of oxygen in the soil, and the top portion will begin to turn yellow and/or light green. Only water when the soil is no longer moist a couple of inches down below the surface.

You may want to turn the plant upside down and lift the pot off. Then examine the outer roots for signs of the healthy cream color. If the roots are brown cut away the outer inch or two of the root ball, repot the plant in fresh soil, and water enough to moisten the soil. Then resume a limited watering schedule. The plants should recover over a few weeks.
