Why are the leaves on my house plant turning yellow?

I have a houseplant that I recently brought back from my workplace. I keep in mainly in artificial lighting similer to the kind it was in before I got it, and am watering it about 1-2 times a week. The leaves are all turning yellow and some are begining to wilt. I am not too good with plants but am trying to improve and would like some suggestions onto what is causing this and what I can do it keep my plant alive and heathly.

I would call myself a pro at plant, I have always been in and around plant. You are giving to much water and your plant has root rot. stop watering it you should only have to water about one time every other week. Give it the finger test feel the dirt it may be dry on top but not two inches down. You can pull the plant out of the soil and check the root system take a peice of the root and pull if the root peels like skin then it is to much water and it is root rot. Good luck...Oh and don't feel bad weman have the problem they take to good of care of their plants...
Reply:It sounds like theres too much water, perhaps you are soaking it too much on those two days that you are watering it.
Reply:thanks
Reply:Give it some natural light, artificial light can't really give it what it needs to thrive. What kind of house plant is it too? Also, for watering, you could be over watering or underwatring it. It all depends on the type of house plant you are talking about.
Reply:If they are yellow at the base, too much water. Not enough if it's at the top of the plant.
Reply:Your plant might be suffering from root rot. Too much water can be just as bad as not enough, water once every week or once every two weeks. Try giving your plant some natural sunlight. Make sure the plant gets some air movement over the surface of its foliage.
Reply:Artificial sun light is ok for some plants. But most need real sunlight. They need rain water for nutrients and stuff they can't get out of tap water.

You might try also thinking of the climate they are in and suppose to be in. Try also transplanting them into bigger pots. Some plants need lots of room to grow. If your soil in the pots are continuously wet then maybe you are watering them too much or too often.
Reply:try changing the humidity the plant is getting.Consider the temperature you had when it was in your workplace. And is it getting enough sunlight?
