I got this from Will Creed - let's hope I don't butcher the explanation too badly in the retelling. First, when you move a
plant to a larger pot, visible growth slows down because the
plant is sending all its energy into increasing its root mass to fill its new space. If you repotted into a much larger pot than the original (more than 2") this can take a long time.
More importantly, however, is that if you repot unnecessarily or into a too-large pot, you risk root rot, especially with
plants that prefer to be on the dry side. The reason for this is when the top inch or two of the soil feels dry, the bottom soil is still moist. Roots require air as well as water; without the opportunity for the lower roots to dry out, they will rot. Over an extended period of time, as the lower roots die, the root rot will gradually spread to the upper roots, eventually killing your
plant.
So if you recently repotted your snake
plant into a much larger pot, you might want to consider downsizing it. Either way be very careful of overwatering. Good luck!
