Hi my name is frank. I have been in love with the art of bonsai since I was a kid. I am finally now seriously getting into it. I was given a crimson maple tree that is basically a 7 foot tall whip. The trunk is about 1 1/4" at the base. I would like to cut it down to about a foot to a foot and a half tall. I would like to know if its possible to cut it so drastically and when the best time to do it would be. I live in N.J. if that helps as far as climate. Thank you in advance for any info.
