Watering is the most important thing. You want to check your medium. If it is bark, it needs more frequent watering schedule. Moss medium takes less frequent. You want to take the orchid out of the decorative pot. And take the plastic pot inside the decorative pot under your sink. Mix your orchid food with the water following the directions on your label. Pour the water all over the medium and let it drain from the bottom. You need to wait until all the water comes out of the bottom before you put it back in the decorative pot. If you live in a dry area, you can get some decorative glass beads, put the beads in a decorative glass bowl and fill it with water and place it next to your orchid for humidity. In 3 weeks or so, once it gets used to its new home; you can repot it and check all the roots. Make sure they are all healthy and not soft or discolored. The dead ones can be cut off. There are a ton of you tube videos that show how to repot an orchid.
Have fun!
