Yep! Something my grandma told me about many years ago. It does work! By the way, I love your teapot.

Nutsedge weed/grass can very easily be pulled up.

Also--if you want to--Home Ddepot sells a spray specifically for Nutsedge.
It comes in "Ready-to-spray"...or in the attach a hose to the bottle and spray method.
