We're going to need more info, such as its growing conditions. Do you grow it inside or outside? What kind of light does it receive? etc.

I grow mine outdoors, where it gets plenty of water and both morning & evening sunlight, and it grows like a weed. I'm already going to have to prune it back and stick the pruned sections back in the pot to make it even bushier. I have it hanging off of my back porch and it's starting to reach the ground. However, when I bring it back inside for the colder months, it doesn't grow quite as fast, and the leaves are slightly smaller. Outdoors, the leaves grow bigger and the green & yellow marbled pattern is much more pronounced.

A lot depends on the climate and conditions it's in.

@tommyboy69 I used to grow it inside my room, and it gets a lot of morning sunshine through the blinds, but sometimes I forget to open them. But then I placed it in the hallway, where it can get a lot of indirect sunlight. Now its outside and almost in the sun.

P.S. I also live in California

I think pothos is slow to take off and then it grows steadily! Don't overpot.

I took home 3 cuttings from my workplace. They haven't grown for almost a year. Since then there are new leaves every week. Just be patient and don't overwater.
