When pruning pampas grass, am I cutting the entire bush down to about 8 inches from the ground?
While the plant is dormant for winter, cut it down as low as you can. This can be done in late fall or very early spring. If it is a large plant, and they can get very large, electric hedge clippers or a small chainsaw come in handy. Use twine or a bungee cord to tie up the top. This gives you easier access to the plant base and quicker clean-up.
