How often to water a bonsai tree?

I have a cheap "tropical" bonsai tree I got from wal-mart for around 10 bucks, It has long, thin grassy leaves coming off it and it is about 20" high, how often should I water it? Should I water it less often because it is a "tropical" tree?|||First rule of watering any plant, bonsai or otherwise, is never set up a regular schedule, but water only when it needs it. Most plants want only to be moist, and not soaking wet; but of course, as with any rule, there are exceptions. GENERALLY, when the top 1/2 inch is dry, water it well, and let the water drain out the bottom holes. You might want to read the Bonsai Care page on my website:
