Philodendron Xanadu Care: How to Care for Philodendron Xanadu

Xanadu philodendron is the most beautiful tropical plant that thrives indoors and in warm weather landscapes. The species grow in clumps rather than climbing like other indoor philodendron varieties.

Philodendron Xanadu care involves the provision of moderate indirect sunlight, well-draining potting soil, medium moisture, and high humidity. Feeding every month during spring and summer is recommendable. Maintain a temperature of 65-85oF (18-30oC).

What Does Philodendron Xanadu Looks Like?

Philodendron Xanadu is pronounced as fil-oh-den-dron zan-ah-doo. The philodendron species is also known as winterbourne.

Xanadu hails from Brazil despite being popular in the United Kingdom and Australia. The philodendron variety generates tropical vibes whether grown as houseplants or landscaping mass.

Xanadu philodendron is a good-looking foliage houseplant that makes lasting impressions in both indoor and outdoor spaces. Thanks to its shiny leaves with multiple lobes.

The multiple lobes result in a cut-leaf philodendron name. This fast-growing philodendron species can reach 120cm tall and 90cm wide.

The Xanadu foliages grow up to a foot long when grown in a container. A mature Xanadu has dark green leaves with a thick trunk and aerial roots along the soil surface.

How to Care for Philodendron Xanadu Plant

Philodendron Xanadu Light Requirements

Xanadu philodendron thrives in moderate to bright indirect sunlight. Filtered natural light prevents the thick stems from growing leggy and falling over.

Direct sunlight exposure cause leaves to scorch and wilt. Low light conditions result in stunted growth and leggy stems.

Place your Xanadu philodendron near the north-facing window. Ensure the window has curtains or shears to reduce sunlight intensity.

Remember to water the plant more often to prevent the thick stems from losing turgidity. Use Grow Led Lights (Check Best Deals on Amazon) in rooms with insufficient natural light.

How to Water Philodendron Xanadu

Philodendron Xanadu loves slightly moist soil to stay happy and healthy. Be sure to water the houseplant when the topsoil 2-3 inches dry out.

I recommend inserting the index finger in the potting mix to determine moisture content level. Soak the potting soil with either rainwater or distilled water until it passes via the drainage holes.

Overwatering can result in fungal diseases that might ruin the health and appearance of your Xanadu plant. Under-watering also makes the plant wilt and die.

Develop a strict watering routine to make your houseplant flourish. Never let your philodendron sits in a damp environment.

Best Philodendron Xanadu Soil Requirements

Xanadu philodendron species prefer rich and well-draining potting mix. The loose soil should retain adequate water without becoming soggy.

I recommend mixing equal amounts of coco coir, peat, and perlite. Add compost to increase soil fertility for vegetative growth purposes.

Repot the indoor plant in case the potting soil exhausts its fertility. The Xanadu plants do experience slow to stunted growth in soil without nutrients.

Philodendron Xanadu Humidity Requirements

Xanadu philodendrons grow well in moderate to the high humidity level. Maintaining indoor humidity levels that meet this tropical plant requirement can be challenging.

Install a digital hygrometer (Check Best Deals on Amazon) to help monitor the indoor humidity fluctuation. Use a humidifier to increase the humidity level in the house.

Be sure to maintain humidity level at around 40-80%. The moist air will keep the plant happy and healthy throughout the year.

Avoid misting Xanadu foliages to reduce the risk of bacterial leaf spots and attraction of sap-sucking insects. The best alternative is to relocate the houseplant to the bathroom.

Best Temperature Range for Philodendron Xanadu

Philodendron Xanadu flourishes at an average indoor room temperature. The ideal temperature range is about 65-85oF (18-30oC).

The philodendron species will grow faster if the temperature is about 73oF (23oC). If you grow the Xanadu philodendron outdoor, ensure the temperature is not below 55oF (12oC).

Keep the houseplant away from radiators, air conditioners, open windows, and doors. Both cold and heat drafts might harm your favorite houseplant.

How to Fertilize Philodendron Xanadu

Philodendron Xanadu is not a heavy-feeder tropical plant. But the houseplant needs fertilizer to enhance vegetative and active growth.

Use a water-soluble balanced fertilizer every month during spring and summer. Do not fertilize the plant in winter due to the dormancy stage.

Too much fertilizer will burn the roots to result in poor growth and yellow leaves. Flush the potting mix with rainwater or distilled water to remove the toxic minerals.

Another excellent option is to repot the houseplant to a fresh potting mix rather than flushing the current soil. It will help to reduce the risk of overwatering problems.

Philodendron Xanadu Flowers

Indoor philodendron Xanadu is more about foliages and not flowers. The plant does not bloom despite ultimate care provision.

Outdoor Xanadu philodendron produces a spathe that is dark with a purple cover around the inner spadix spike. The spadix contains a myriad of tiny flowers.

Pruning and Maintenance

Xanadu philodendron requires a minimal trimming routine. I recommend removing dead or damaged foliages to maintain a compact shape design.

Use a sharp and sterilized pruner (Check Best Deals on Amazon) to remove dead foliages and stems. It helps to redirect energy to the growing regions or parts.

How to Repot Philodendron Xanadu

A less frequent repotting routine is the best philodendron Xanadu care. Every houseplant enthusiast needs to repot the plant in case of root-bound issues.

Root-bound causes stunted growth and yellowing of leaves. I recommend repotting the houseplant in spring and not winter due to dormancy.

Use well-draining soil and water the plant every 2-3 days. Besides that, ensure the new container is about 1-2 inches more than the previous one. Large pots increase the risk of overwatering.

Philodendron Xanadu Propagation

Root division and stem cutting are the best methods for propagating philodendron Xanadu. The philodendron species is highly vulnerable to root rot and direct sunlight.

Divide the roots into sections during spring and plant each part in its pot. Water the parts more often until the roots become resilient.

Stem cutting propagation is the most challenging to novice houseplant growers. Cut the stem about 3-6 inches long and implant it in the soil. Keep it warm and under indirect sunlight.

Common Problems and Solutions


Xanadu philodendron is more susceptible to houseplant pests. Spider mites, scales, and fungus gnats are the most common sap-sucking creatures that attack the Xanadu plant.

Use neem oil solution or insecticidal soap to kill these houseplant pests. Be sure to isolate the indoor plant from other plants to inhibit the spread.

Allow the potting soil to dry between the watering gaps. A damp environment encourages these houseplant pests to thrive.


Xanadu plant is vulnerable to bacterial and fungal diseases with improper care routine. A damp potting soil condition encourages fungal spores to multiply.

Bacterial diseases cause root rot and leaf spot. I recommend repotting the houseplant to save it from dying. Use sterilized containers and fresh potting soil.
