There is a saying that a plant will only grow as big as its pot, however, it's fair to say that a trailing pothos plant can get pretty large before you might notice its current pot simply isn’t big enough to accommodate its size.
With any plant, the roots need space to expand and grow, and there needs to be enough space in the soil for water and nutrients to be absorbed by the roots for it to stay healthy. Without enough space, plants can struggle or die. Therefore in addition to pruning your pothos it’s important that you know how to repot it.
