We cut the pampas grass and used a small light weight tarp for cleaning up the clippings. After putting it on the tarp, I tied the bottom ends of the tarp together in a loose knot, then tied the other end to give me a good grip to drag it. It took 3 trips and the tarp worked great for dragging the heavy clippings to the brush pile. It was easy to roll them off after I untied the ends.
This is a good tip. Saves some work and its frugal or thrify for sure. I just got a free tarp from Harbor Freight coupon a couple weeks ago so I know what I will use it for now. Thank you!
