Philodendron schmidtiae

Natural range and habitat of Philodendron schmidtiae

Philodendron schmidtiae is native to Ecuador, where it grows in the wet tropical biome.

Growing Philodendron schmidtiae indoors

Support and pot stability: Use a broad, rigid pole or plank and anchor it securely. The stout stem and very large leaves can make a light container unstable as the plant gains height.

Light and temperature: Position it in bright indirect light and shield the broad leaves from strong sun. Keep temperatures around 18–29 °C and above 15 °C, away from hot radiators and cold draughts.

Humidity and airflow: Provide about 50–60% humidity. Steady humidity is useful while the very large leaves expand. In a dry heated room, a humidifier can reduce repeated crisp leaf edges. Keep air moving around the upper stem so its persistent fibres dry promptly after watering.

Water and potting mix: Use a coarse mix that holds some moisture and stays open around the large root system. Check below the surface before watering because the centre of a substantial pot can remain wet after the top has dried. Water thoroughly only when the mix is dry enough, then let the excess drain.

Feeding: During active vine growth, give complete houseplant fertiliser sparingly. Use a lighter feeding schedule once growth slows.

Repotting: Repot when roots crowd the container, the mix compacts or the support becomes unstable, using a pot only slightly larger than the root ball.

Propagation: Choose a healthy cutting carrying a node. An established existing aerial root is useful but not essential.

Troubleshooting Philodendron schmidtiae

• Several leaves yellow or wilt while the pot stays wet: Delay watering and check the centre of the root ball. If decline continues, inspect the roots and preserve all firm tissue. Cut only clearly rotten, soft root sections back to healthy tissue with disinfected scissors and discard them. Replace collapsed mix with fresh, airy substrate if needed.
• Old sheath fibres become wet, soft or smelly: Remove only loose decomposing material and keep the exposed node dry and ventilated. If the stem softens, cut back to firm healthy tissue with a clean tool.
• White cottony clusters or sticky residue appear among the old fibres: Isolate the plant, remove accessible mealybugs and treat the nodes and petiole bases with a houseplant product labelled for mealybugs. Follow the label for repeat timing; see our mealybug guide.
• Hard brown or tan bumps remain fixed around nodes or petiole bases: Isolate the plant, remove accessible scale insects and use a houseplant treatment suitable for scale. Follow the label for repeat timing; see our scale insect guide.
• New leaves become progressively smaller: Check light, root health and whether the climbing stem is still securely supported. Correct the limiting condition before increasing fertiliser.

Philodendron schmidtiae is toxic to people and pets

• Keep this plant away from children, cats and dogs.
• Its leaves and stems contain insoluble calcium oxalate crystals, which can irritate the mouth, throat, skin and eyes.
• Chewing may cause burning pain, drooling, swelling, vomiting or difficulty swallowing. Contact a veterinarian or medical professional after exposure, especially if swelling or breathing problems occur.

When and where was Philodendron schmidtiae first published?

Philodendron combines Greek philein, meaning “to love,” with dendron, meaning “tree.”

Heinrich Wilhelm Schott established the genus Philodendron in 1829 in Wiener Zeitschrift für Kunst, Literatur, Theater und Mode, volume 3, page 780.

Thomas Bernard Croat and Carlos E. Cerón first described Philodendron schmidtiae in 2013 in Aroideana, volume 36E, issue 1, page 60.
