Do you mean trim the roots to keep plants miniature like Bonsai growers do or use scissors instead of a knife when repotting? If you mean the latter, I generally trim large rootballs with a knife because it's quick and uniform. However, with smaller shaggy rootballs I've used a small sharp pair of medical scissors (I also use them to cut off faded blooms). The scissors work very well and the plants don't mind at all.

Just regular trimming of roots after trimming older leaves. I had never heard anyone mention using anything but a sharp or serrated knife on this forum. I plan to get a pair of quality small scissors.

Thank you for your time Thom

Thom,
I use an old pair of scissors to trim the root ball when I repot.

I too use scissors to trim a root ball. Actually, I don't even have a knife in my tool kit, unless you count an exacto type knife.
