Philodendron selloum is a tropical plant from the Brazilian rain forest, where its broad leaves grow 2 feet wide on the 15-foot-tall plant. The foliage also has pronounced lobes formed by deep contours. In the United States, the heat-loving shrub grows as an indoor plant, except in U.S. Department of Agriculture hardiness zones 10 to 12, where it thrives outside. As a potted plant, Philodendron selloum produces leaves of a more modest size and shape and it rarely flowers. A simple way of propagating philodendrons is by stem cuttings.
Fill a 2-inch pot with 1 part peat moss and 1 part sand uniformly blended.
Irrigate the rooting medium until excess water flows out of the drainage holes.
Select a philodendron stem with at least two nodes and cut it off the plant.
Plant the cutting in the peat-moss blend. Verify that the bottom node is below the surface; roots will sprout from it.
Water the cutting at planting. Keep the soil consistently moist to encourage root development.
Cover the stem with a clear plastic bag to create a warm and moist environment. Set the pot in indirect sunlight.
Dig gently around the stem's base to check for roots once a week. Transplant a newly rooted Philodendron selloum to a 3-inch pot filled with potting mix. Upgrade to a 5-inch container when the roots outgrow the current planter. Next time the roots become too long again, move the philodendron to the ground if you live in hardiness zones 10 to 12. Otherwise, transplant it to a bigger pot.
