I remember when I was younger I watched the movie KARATE Kid and saw Mr. Me-agee trimming his Bonsai Trees! I think he did it blind folded...or maybe that was him trying to catch the flies with chop sticks
In any case Bonsai Trees are a great hobby, you just have to keep on watering them and make sure they do not dry out. Many places recommend that you soak your bonsai tree instead of watering from the top.
