How to care for Tree Philodendron
Thaumatophyllum bipinnatifidum · Araceae
A sculptural floor plant (formerly Philodendron selloum) with huge, deeply lobed leaves on long stalks rising from a thick, trunk-like base. Given room and light it becomes a statement plant well over a metre across, with dramatic aerial roots. It is tolerant and long-lived, asking mainly for space and reasonable watering. Water roughly every 8 days while it's growing (about every 13 in winter), give it bright, indirect light, kept above 54°F (12°C) — average room humidity suits it.
Care at a glance
Water deeply when the top 2 inches (5 cm) dry; big pots hold moisture longer than you expect, so always check first.
Bright indirect light or gentle morning sun; in dim rooms the leaf stems stretch long and floppy.
Balanced fertilizer at half strength monthly — big leaves need steady nutrition.
Mistakes that kill this plant
- Overwatering a large, slow-drying pot in winter.
- Confining a naturally huge plant to a dark corner.
- Repotting into a pot several sizes too large, keeping roots wet for weeks.
Seasonal tips
- Wipe the big leaves down monthly — dust dramatically cuts their light intake.
- Rotate regularly so the crown grows evenly instead of leaning to the window.
- Water sparingly in winter; the thick base stores moisture.
