Yep! I wanted to kill the pervasive bermuda grass without RoundUp, so I used ChipDrop in late 2021 and got something like 70 cubic yards of mulch piled on my front lawn. Gave a little bit away, but used most of it to bury the grass around my front yard garden, which is about 1,750 square feet in total. Here’s a before and after.

Annoyingly the grass is so persistent, it’s still poking up through the mulch, but by pulling those stolons when they appear, we’re slowly winning a war of attrition. I don’t use the mulch on my raised boxes or where I’ve planted in the ground, there I use straw, but I run drip lines under the straw so it really shouldn’t matter for water infiltration.

I have noticed a massive uptick in the bugs in my yard, the mulch is decomposing fast and is loaded with worms, millipedes, grubs and beetles, which has brought a lot more birds around too. I also noticed that the tomatoes I planted in the ground adjacent to the mulch took off way faster than those in my boxes, despite the boxes having been filled with the same soil from the front yard (excavated for a driveway expansion), and lovingly amended with excellent compost.
