Philodendron xanadu prefers bright indirect sunlight but can live in lower light conditions. When this plant receives less than 5 hours of indirect sunlight each day, its new leaves will emerge smaller, its vines will become leggy, and vibrant colors and variegation may fade! If your home doesn't have bright indirect sunlight, you can use artificial light as a supplement. We recommend LED grow lights turned on for 8-10 hours daily!

Your Philodendron xanadu plants soil should be watered thoroughly after the soil is completely dry. It indicates that it needs water when the leaves start wilting. Water more often in the growing season and reduce the frequency during winter. It is best to refrain from watering if you cannot decide whether to add more.


Philodendron xanadu (and all philodendrons in general) love loose, nutrient-rich potting soil. Use a soil medium that can retain moisture but allows for draining excess water to avoid root rot. Most pre-mixed soils will suffice. Ensure plenty of organic matter, like coco-coir, peat moss, or shredded leaves, and prevent soil containing moisture-retaining crystals. If your soil drains too quickly, we recommend repotting it into a compost-rich soil mixture with fewer drainage materials.


Most household temperature ranges (65-80°F) are adequate for your Philodendron xanadu plant during the daytime. Philodendron xanadu plants can tolerate cooler temperatures at night, down to around 60 degrees, however, don't allow this plant in temperatures below 50 degrees. It can stunt your plant's growth, and prolonged exposure to cold temperatures can be fatal for this tropical indoor plant. 


Like most tropical indoor plants, Philodendron xanadu will benefit from higher humidity but do fine in average household air. Higher humidity (over 50%) is always better for tropical houseplants like this one. To increase humidity for your plant, you can mist the leaves, use a humidifier, provide a tray filled with water and pebbles near the plant, or group plants together! Also, you must avoid low humidity. 


A Philodendron xanadu plant will benefit significantly from regular fertilizing because it is a fast-growing houseplant! Use a weak solution (diluted to ¼ the recommended strength) of a complete liquid fertilizer every four to six weeks throughout the growing season. Do not fertilize during the winter months. Sometimes this indoor plant will grow all year long.

Growth Rate

Philodendron xanadu plants can reach a mature height of around 2 to 4 feet (60 to 120 cm) or more. It is dependent on the specific conditions and care provided to your plant.

Pro Tips

  1. Don’t let your Philodendron xanadu receive exposure to the direct sunlight, as it can burn the leaves of your plant.
  2. Avoid overwatering this plant as the Philodendron xanadu is susceptible to root rot in soil that is soggy.
  3. We suggest you wipe the leaves of you plant carefully with a damp cloth to get rid of dust and to keep them clean. This will help promote better photosynthesis.
  4. Repot your plant when it becomes root bound or if the potting mix has broken down. Usually, repotting is needed every 2-3 years.
