Pick a section of the philodendron stem that contains at least one node -- a budlike bump -- and a leaf.
Cut the stem so it is about 1 1/2 inches in length with sharp scissors, pruning shears or pinch it off with your fingers.
Fill a small pot full of well-drained quality potting soil.
Plant the stem cutting at a depth of 1/2 inch.
Water the philodendron so that the soil is moist, yet not over saturated or soggy. Drain off any excess water that leaks out the holes in the bottom of the pot. Philodendrons thrive best in moist soils that you allow to dry out between watering.
Place the pot in indirect sunlight or a shady area outdoors. Philodendrons grow best in areas with nighttime temperatures around 60 degrees and daytime temperatures of 70 to 75 degrees Fahrenheit.
Wait about three to five weeks for new buds to appear. Rooting takes place in approximately four to six weeks.
