How to fertilize Thaumatophyllum Xanadu
Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Thaumatophyllum Xanadu after it doubles in size or once a year—whichever comes first.

Im starting to feel like i’m losing her, how can i lift her spirits again yall 🫶🏾

Limp and yellow leaves My philodendrons old leaves are yellowing and the new leaves have black around the edges. What’s its problem and how do I fix it? #Philodendron

I am not sure if a philodendron Xanadu is the same as a philodendron Tiger Tooth Can someone bring me clarity? #CutLeafPhilodendron
-
Hey Greg! Any reason why this guy’s so droopy? He’s sprouting new stalks but his bigger ones just seem to fall. Is this normal? Does he need a deeper pot? #Philodendron #HappyPlants
-
Lots of Yellowing leaves Any help would be great! In the same pot as I got from the plant shop. Been watering according to soil.

Before and After! This plant had long slim leaves when I bought it. As it matures, the leaves grow more defined and wide. They look like grinch fingers 😂 #HappyPlants #PlantsMakePeopleHappy #Philodendron #xanadu

How do I treat this? #CutLeafPhilodendron

Hi, can anyone help identify what’s going on with my split leaf? I was checking over my plants yesterday and it’s got some yellow spots on top so I flip it over to inspect further and it’s like its got a bunch of little glass balls or water droplets. They were hard to the touch but if you crushed them (by mistake) they were sticky. They just looks so so shiny like glass balls though. I’ve attached pics #NewPlantMom #PestControl

Can I? Should I? Can I or should I give this beauty a moss pole? If so- what’s the best way to make it work for her? Don’t get me wrong- I love how big she’s getting, but it’s getting harder to find the right spot for her. She’s been giving me a new leaf every couple of weeks since my mother in law gave her to me. Thoughts? #HappyPlants #PlantsMakePeopleHappy #PlantAddict #NewGrowth #PlantCorner #Philodendron
Thaumatophyllum Xanadu is generally easy to care for, though some plant parents report facing challenges with growing it. Check out the reviews down below to read more about their experiences!
💦 Water Needs
Thaumatophyllum Xanadu prefers for the soil to dry out between waterings and should be watered regularly. Use our water calculator to personalize watering recommendations to your environment or download Greg for more advanced recommendations for all of your plants.
☀️ Sunlight Needs
Thaumatophyllum Xanadu may have difficulty thriving and will drop leaves 🍃 without ample sunlight. Place it less than 3 feet from a window to maximize the potential for growth. Select your region to see how the current weather in your area affects the placement in your home 🏡.
🐶 🐈 👶 Toxicity
Thaumatophyllum Xanadu is not safe to consume. If you, a family member, or a pet has ingested any amount of plant material contact Poison Control, US (800) 222-1222, or your veterinarian. If you have children, cats, or dogs in the home, we suggest keeping this plant out of reach.
💨 Humidity
Thaumatophyllum Xanadu doesn’t require additional humidity. Plants absorb most water through their root system rather than their leaves, so the best way to provide humidity for your plants is through watering the soil.
🪴 Soil
Thaumatophyllum Xanadu does best in well-draining soil. A good soil will contain lots of organic matter such as coco coir as well as perlite or vermiculite to help with drainage. Adding a handful of perlite to regular store-bought potting soil should do the trick!
💩 Fertilizer
Thaumatophyllum Xanadu should be repotted after it doubles in size or once a year, whichever comes first. Fresh potting soil has all the nutrients your plant needs, so as long as it’s refreshed yearly, you shouldn’t need to use fertilizer. Remember, plants get their energy from sunlight, not fertilizer!
🌎 Native Region
Thaumatophyllum Xanadu is native to Tropical South America.
🌸 Flowers
Yes, you may see your Thaumatophyllum Xanadu bloom with the right amount of sunlight and water.
⬆️ ⬇️ Growth Pattern
Thaumatophyllum Xanadu is a naturally climbing plant and can be trained to climb indoors if you provide a moss pole or trellis. The newest growth will emerge from the end of the stems.
🌦️ Growing Outdoors
USDA Hardiness Zone
Thaumatophyllum Xanadu can be grown outdoors in USDA Hardiness Zones 10a-12a. Find your local hardiness zone here.
🌱 Propagation
Thaumatophyllum Xanadu can be propagated by the stem method. To propagate:
- Make a cut just above the node. The node is the break in the stem where the leaf emerges.
- To get the cutting to root, you can either:
- Place the cutting in water until roots emerge and are ~2” long and then transplant into well-draining soil, or
- Place the cutting directly into well-draining soil and water when dry.
🍂 Yellow Leaves
Yellow leaves aren’t always a reason to panic, and can be a normal part of a plant’s life cycle. Unless brand new leaves are turning yellow or all the leaves change color at once, it’s likely just your plant shedding old leaves.
Overwatering and root rot are the most likely cause of problems in Thaumatophyllum Xanadu, since they are sensitive to wet soil. The leaves may also appear to be curling or drooping. Less often, yellow leaves are caused by underwatering, nutrient deficiencies, or pests.
Replace soggy soil with fresh, dry soil and download Greg to make sure your plant never gets overwatered again!
🧐 Troubleshooting
When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.
Inspect the soil moisture; too dry or too wet soil can cause problems.
Ensure the plant is getting the right amount of light, as too much or too little can stress it.
Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.

Care Summary for Thaumatophyllum Xanadu
Thaumatophyllum Xanadu
Greg recommends:
0.5 cups every 9 days
< 3ft from a window
Repot after 2x growth
Based on the 4” pot your plant is in, and that it doesn’t get direct sunlight.
What other plant parents say
When I first got the plant it was super root bound in the container I brought it home in. Then it got root rot. I trimmed the bad leaves and replaced all the soil with new soil which saved her and she has grown new leaves quickly.
Watch for mushy leaves and trim them quickly or they spread to the rest of the plant!
