Welcome to bonsai and to Bonsai Nut.
You probably know where you are and what the weather and climate is like but none of us do. Adding a location to your profile will help members give better advice based on your location and climate.
For now care consists of watering when it needs water and trimming any long shoots. Fertilize every few weeks through the growing season (which will depend on your location and where you keep the tree).
Just concentrate on keeping it alive for the first year which is often easier said than done.
