Care Essentials
Get to Know Your Philodendron Xanadu
The #1 killer? Overwatering. Let the soil dry between waterings and your Philodendron Xanadu will thrive.
Light
medium to bright indirect
Most comfortable in medium to bright indirect light. Avoid prolonged direct sun exposure.
💡 Grow lights: Thrives under artificial grow lights (LED or fluorescent, 10-12 hours/day). A great option if your space lacks natural light.
Watering
every 10-14 days
Let the soil dry out significantly between waterings — this plant is very sensitive to overwatering. When in doubt, wait another day.
Humidity & Temperature
Appreciates some humidity but adapts to average home conditions. Brown tips in winter? Your air might be too dry — a light misting helps.
Standard room temperature (60-80°F / 15-27°C) is perfect. Avoid cold drafts and sudden temperature swings.
Soil
Needs well-draining soil — add perlite or orchid bark to a standard potting mix. Good drainage is critical to prevent root rot.

Why are my Philodendron Xanadu leaves turning yellow?
Yellowing lower leaves on philodendrons most commonly trace to overwatering or to a winter chill, but heat too high, humidity too low, soil that swings between bone-dry and waterlogged, and cold water on the foliage can each yellow leaves across the canopy

Why are my Philodendron Xanadu leaves turning yellow?
Yellowing lower leaves on philodendrons most commonly trace to overwatering or to a winter chill, but heat too high, humidity too low, soil that swings between bone-dry and waterlogged, and cold water on the foliage can each yellow leaves across the canopy
Cause
Yellowing lower leaves on philodendrons most commonly trace to overwatering or to a winter chill, but heat too high, humidity too low, soil that swings between bone-dry and waterlogged, and cold water on the foliage can each yellow leaves across the canopy.
Solutions
- Let the top inch of potting mix dry between waterings and reduce watering frequency in winter; water thoroughly so excess drains from the pot.
- Use tepid or room-temperature water and avoid wetting leaves in cold conditions to prevent yellow or white rings forming on foliage.
Prevention
Maintain steady indoor temperatures, water only when the mix begins to dry, and keep humidity moderate (around 30 percent) so philodendrons do not yellow from combined heat, dry air, and erratic watering.
Diseases (1 topics · 1 cases)
Why does my Philodendron Xanadu have root rot?
Root rot on philodendrons is almost always the result of waterlogged, poorly drained potting mix, compounded by pots without drainage holes or compacted, sour soil that suffocates the roots and lets the plant collapse
80%
Why does my Philodendron Xanadu have root rot?
Root rot on philodendrons is almost always the result of waterlogged, poorly drained potting mix, compounded by pots without drainage holes or compacted, sour soil that suffocates the roots and lets the plant collapse
Cause
Root rot on philodendrons is almost always the result of waterlogged, poorly drained potting mix, compounded by pots without drainage holes or compacted, sour soil that suffocates the roots and lets the plant collapse.
Solutions
- Tip the plant out, shake off the soggy mix, cut away any black or mushy roots, and repot into a fresh, well-draining aroid mix in a container with drainage holes.
- Allow the potting mix to dry back between waterings and hold off on feeding until new growth resumes so the plant can recover from root loss.
Prevention
Use containers with drainage holes, water only when the top of the mix begins to dry, and refresh compacted soil at repotting so philodendron roots never sit in saturated, oxygen-poor conditions.
Pests (2 topics · 2 cases)
Why does my Philodendron Xanadu have mealybugs?
Mealybugs appear as white cottony clusters tucked into the leaf axils and stem joints of philodendrons, sapping the plant and producing undersized, spindly foliage along with an overall loss of vigor

Why does my Philodendron Xanadu have mealybugs?
Mealybugs appear as white cottony clusters tucked into the leaf axils and stem joints of philodendrons, sapping the plant and producing undersized, spindly foliage along with an overall loss of vigor
Cause
Mealybugs appear as white cottony clusters tucked into the leaf axils and stem joints of philodendrons, sapping the plant and producing undersized, spindly foliage along with an overall loss of vigor.
Solutions
- Dab individual bugs and small colonies with a cotton swab dipped in rubbing alcohol, then wash the plant with soapy water and rinse clean.
- For heavier outbreaks, spray with Malathion following the label, or apply a soil-applied systemic insecticide for longer protection.
Prevention
Inspect new plants before adding them to the collection, wipe foliage weekly with a damp cloth to remove eggs and crawlers, and discard any heavily infested plant to prevent mealybugs spreading to healthy philodendrons.
Why does my Philodendron Xanadu have spider mites?
Microscopic red spider mites colonize philodendrons in dry indoor air, leaving fine webs at leaf and stem axils and causing leaves to mottle, turn gray or brown, and become dry and crumbly
80%
Why does my Philodendron Xanadu have spider mites?
Microscopic red spider mites colonize philodendrons in dry indoor air, leaving fine webs at leaf and stem axils and causing leaves to mottle, turn gray or brown, and become dry and crumbly
Cause
Microscopic red spider mites colonize philodendrons in dry indoor air, leaving fine webs at leaf and stem axils and causing leaves to mottle, turn gray or brown, and become dry and crumbly.
Solutions
- Spray the plant forcefully above and below the leaves to break the webs, then mist regularly to raise humidity around the foliage.
- Treat a heavy infestation with a miticide spray such as Dimite or Aramite, applied to the undersides of leaves where the mites feed.
Prevention
Keep humidity moderate by misting foliage weekly and wiping leaves with a damp cloth, since spider mites thrive in dry indoor air and rarely become a problem in a humid atmosphere.
