I just want to know how to keep skimmia plant alive? Do I hide it from sunlight and how much do I water it (daily, twice a week, etc..???)?
Also can I keep the skimmia plant in the pot of soil that I bought it with or I have to plant it in another pot?
These are shade plants. You will want to keep the area around them moist, but not wet. That means you will check and see if the soil is dry on top, and if it is, that is when you will water it again. It can take longer to dry during wet periods, and can dry very quickly in dry spells. This article will give you more information on the care of these: https://www.gardeningknowhow.com/ornamental/shrubs/skimmia/growing-japanese-skimmia.htm
