Q.pampas grass seems to have died on one side
My pampas grass seems to be dead on one side. Is this the case and should it be removed or will it come back on its own? The other side is growing fine while the seemingly dead side is brown with no new growth. It was a long and hard winter. My thought is that this may have damaged it.
Yes, I'd guess that the one side was more protected than the other. Cut the dead part down to the ground, the grass may be able to send new shoots up on that side, if the roots are okay.
