This is why you don’t pull Nutsedge

I don't know who needs to see this, but I hope this helps someone understand.

As you can see at the very bottom of the root base, there are "nutlets". These nutlets are connected by very weak roots and extremely prone to break off when pulled out. Also, as you can see, there are often more than one. The second one broke off here just from very gently juggling it in water to attempt to clean it off. If you leave that nutlet in the ground, it will obviously grow back.
