Will be hard to tell you excatly how to care for that grass without
knowing its name.
Put the plant in a bright windows ( SE, S, SW or W exposure) but out of the
direct light of the sun. Water sparingly, no more than maybe once a week
every 2 weeks might be better. IF you water too much, you will drown its
roots and it will certainly die. Check for water by lifting the pot, if it
feels light, then give a good deep drink. You can verify by sticking your
finger into the soil.. If the top inch or two is dry, then water.
Try to find out its name, if you possibly can.. Can get mre accurate
guidelines from the group if you do.
