Pothos tend to become stringy looking if they don't get enough light and/or they are not pruned back regularly. In
greenhouse light you can grow long, health vines. In home light, long strands eventually start to lose leaves at the soil end.
In general, when a stem grows more than 12 to 18 inches long, it should be cut back to a length of 3 to 5 inches. New leaves will then start to grow at the end of that shortened stem, close to the soil. That will keep the
plant full and compact looking.
Pothos cuttings can be rooted in water or in moist soil. Tip cuttings that have no more than 4 leaves will root more readily than longer cuttings. Cuttings have about a 75% rooting rate. That means about 25% of the time, the stem rots before roots develop.
For cuttings rooted in water, wait for roots to grow about an inch long before transferring them to soil.
