Name: greene Savannah, GA (Sunset 28) (Zone 8b) I have no use for internet bullies!
Sharp pruning shears work good. Electric or gas powered hedge trimmers work very good also.
If you would first take the time to tie the grass into a "pony tail" tied with twine then cut below the twine cleanup will be much easier.
