Using the sterilized knife, slice off the bottom 2 in. of root ball (or less, if the plant is in smaller than an 8-in. pot), like you see here. Tease out the remaining roots with your fingers to loosen thick tangles. Then shear off 1 in. of these feeder

Tease out the remaining roots with your fingers to loosen thick tangles. Then shear off 1 in. of these feeder roots all around the circumference of the root ball.
