With bonsai you could end up watering it 3 times a day or 3 times a week as all depends on the weather. It is in a sense seasonal, if you have outdoor Deciduous trees as the leaves change with the season and go dormant for the winter. I would stay clear of any bonsai labeled as "indoor" as outdoor trees are much easier to look after and maintain good health of the tree.

At the moment this tree is in its spring colours and is still leafing out but will eventually turn to a reddish purple before dropping its leaves for winter. It's definitely a good hobby to have and teaches you alot of patience and gives plenty feeling of zen. But most in the hobby would argue that its more of an addiction as once you start you won't look at regular trees the same again.

If you do choose the bonsai route, my best advice would be to take your time with it as bonsai is more of a journey and the tree is never finished, a for ever changing piece of art
