In its native tropical environment, pothos (Epipremnum spp.) grows to several feet with leaves that can measure up to 2 feet long. A sturdy vine, pothos wraps itself around other plants, such as trees, or trails across the ground, making it useful in warm climates as a dense ground cover. Below U.S. Department of Agriculture plant hardiness zones 10 through 11, where it grows outside as a perennial, pothos, also called devil's ivy, can be grown as a houseplant. An aggressive grower, pothos can quickly become overgrown and tangled, but you can trim it and save the cuttings to grow new plants. You can root these cuttings in water.
1 Unwind one of the longest vines and cut it a few inches above the soil. Lay it on several thicknesses of newspaper to absorb the moisture that leaks out of the cut ends.
2 Start from the leafy end of the vine, and find the root nodes along its length, which appear as small yellowish-brown nubs protruding from the green tissue.
3 Make a cut about 2 inches below the first root node at the leafy vine end, and make other cuts every 6 inches along the rest of the vine. Include at least one node and two or three leaves on each section.
4 Fill vases or cups halfway with water and place one cutting in each vase. Adjust the water level so it is over the node. Remove any leaves that are below the water.
5 Place the vase in an area that receives filtered sunlight, as pothos dislikes intense direct light. Add more water, as needed, to keep the water level above the root node.
