Philodendron maximum is a magnificent and truly impressive aroid, celebrated for its exceptionally large, deeply lobed leaves and vigorous climbing nature. This Philodendron species features broad, glossy green foliage that can attain immense dimensions, often with prominent veins and a somewhat wavy margin. Its imposing size and lush appearance make it a dramatic focal point in any spacious indoor setting in the UK. It is a member of the Araceae family.
The genus name Philodendron comes from Greek words, reflecting the plant's tendency to grow on trees in its native environment. Maximum refers to the plant's potential to grow very large, particularly its leaves.
Light: Philodendron maximum thrives in bright, indirect light. Strong, direct sunlight can damage its leaves, while insufficient light may result in slower growth and smaller foliage, diminishing its characteristic grandeur. A position near a window with filtered light in a typical UK home is ideal.
Water: The potting mix should be kept consistently moist but not saturated. Allow the upper inch or two of the soil to dry between waterings. Ensure the pot has excellent drainage to prevent root issues, which can be a common problem, especially in the UK's climate.
Soil: An airy and well-draining potting mix is essential. A mix specifically formulated for aroids, incorporating materials such as coco coir, perlite, and orchid bark, is often recommended to provide the necessary aeration and drainage.
Fertilising: Use a diluted liquid fertiliser every two to three weeks during the active growing period in spring and summer. Reduce or stop fertilising during the autumn and winter months when the plant's growth naturally slows. This species is considered a heavy feeder due to its potential for large growth.
Temperature: This plant prefers warm temperatures, ideally between 18°C and 29°C (65°F and 85°F). It should be shielded from cold drafts and sudden temperature changes, which can occur indoors, particularly during colder UK months.
Humidity: Higher humidity levels are highly beneficial for Philodendron maximum. Consider using a humidifier or placing the plant on a pebble tray with water to maintain optimal conditions, especially during drier indoor periods in the UK.
Growth Habit: This Philodendron has a strong climbing growth habit. To encourage its impressive leaf size and vertical development, providing a sturdy support such as a moss pole or tree bark is crucial. It will produce aerial roots that cling to these surfaces.
Toxicity: Like all Philodendrons, this plant is toxic if ingested by humans or pets.
