Watering on a schedule is a mistake. You should let the soil dry out a bit in between thorough waterings, a little bit each day is the wrong approach.
The first order of business is to identify the plant. Post pictures if you are able. Go to google and check the following candidates. Juniper, Ficus, Serissa, Fukien Tea, Chinese Elm. Proper care depends upon a proper identification.
You are lucky in that you have a family member with experience, I would avail myself of your uncles experience. Ask him about watering techniques, soil, fertilizing, etc.
