Thankfully, growing a potted plant is pretty simple. It begins by selecting a pot that will fit your plant, usually one that's only an inch or two larger in diameter than the container your plant is currently in. Add some soil to your new planter, place your plant in, and fill in any gaps with more soil. Give it a good water, and let the plant do its thing. Make sure you keep the potted plant in an area that gets plenty of light and water it according to the suggested amount based on the type of plant you have.
