Yesterday i was outside and i noticed a little maple in a small tree line at
the edge of my property.it must've been mowed over in the past couple of years
and has stayed small and has interesting scarring on one side. BRBR

Before you waste any time, find out what kind of a maple it is. If it is a
seedling of a nearby street tree, it is probably a Norway maple and useless for
bonsai.
