I'm either an expert at mulching or doing a really crappy job b/c it doesn't take me that long at all. I get a ton of bags - dump them all over the yard, open 'em up and spread them out.
What am I missing? It takes me longer to go to Home Depot and get the bags (at least 2 treks) than the actual mulching part. And if you're having it delivered, that cuts out that step.
You'll need a wheelbarrow, shovel and a rake type of thing to spread it. That's it.
