How to Care for a Philodendron Xanadu

Use these instructions to care for a Philodendron Xanadu. This guide will tell you how to water your Philodendron Xanadu; its light, temperature, and humidity preferences; and any additional care your plant might need to help it grow.

Light Requirements

Your Philodendron Xanadu prefers medium to bright indirect light—placing it near an east or south-facing window is ideal. It will, however, survive in lower light and the leaves will turn a darker green. Direct sun or too much light will burn or fade the leaves.

Water Requirements

Water your Philodendron Xanadu when its soil becomes dry to a depth of 1-2 inches. Water the plant until water flows into the saucer, then pour out any excess. Don’t allow the pot to stand in water, as this will cause root rot. During the winter, water less often, keeping the soil barely moist.

Humidity Preference

Your Philodendron Xanadu will tolerate the level of humidity found in most homes, but high humidity promotes lush growth and shiny foliage, so it is a good idea to mist the plant regularly.

Optimum Temperature

Your Philodendron Xanadu likes warm temperatures above 55 degrees. Keep them away from drafts and open doors, especially during the winter.

Plant Food

Fertilize monthly during the spring and summer with a balanced, water-soluble fertilizer diluted to half the recommended strength. Never apply fertilizer to dry soil, always make sure soil is damp before applying plant food.

Additional Care

Yellow leaves on your Xanadu occur naturally as new growth comes in or if it is acclimating to a new spot in your home. Remove these yellow dead or dying leaves regularly by snapping them off where the leaf stem touches the primary stem or the soil surface. It is also a good idea to periodically look between the dense foliage and remove the dried leaf husks left behind when a new leaf is produced. Regularly clearing away this dead organic material prevents mold, fungus, and worst of all Fungus Gnats.


Philodendron Xanadu leaves are toxic to pets and humans. Typically, ingestion will result in swelling of the lips and tongue, and stomach irritation with possible vomiting.
