How to Care for a Swiss Cheese Plant
I recently purchased a Swiss Cheese plant a few weeks ago. I would like to know how to prevent the leaves from turning yellow and from drying out? Also, I want to know if I need to repot the plant? I noticed that the leaves were turning black and yellow. The plant gets direct sunlight and is in my living room. I water the plant once a week and mist the leaves to prevent it from drying out. Could the plant be receiving too much sunlight? I am a new grower and don't have any experience with houseplants. I would like to see this plant grow strong and healthy, so your advice is needed.

With houseplants, you should not be watering on a schedual, but rather checking on a schedual. Water the plant when just the very top of the soil is dry.
It sounds like it may have a bit of a fungus, which is causing the black spots and yellow leaves. Treat the plant with a fungicide. Since you know now that it is prone to fungus in that spot, you may be better off setting it on a pebble tray filled with water rather than misting to help with the humidity.
You probably do not need to repot it at this time. They like to be a little root bound.
