A couple winters ago the utility company had a crew cutting limbs along their distribution lines and they had good sized truck with chipper & box , I asked the guys if they would like a place to dump at end of day and invited them to my place right down the road .Sounds better then the mountain clay I got lol. Got a lot of leaves and wood dirt mixed in for this year. Last year got a truck load of peat moss. It's looking better this year. But well see how she produces.
Believe it was 60 total yards they dumped that week and I just spread it out with the plow on my ATV , the following year I grew some nice sugar babies through that stuff.........my place use to be a dairy farm so the soil is plenty fertile to begin with and the mulch is mostly intended for weed control but is a great soil builder also.
Nice simple and free way to get mulch , in the summer I'll take a 2 yard trailer with sides that I built from an old boat trailer and go to the local burn site where they accept all yard waste ........there are several mounds of wood chips , leaves , grass clippings and black dirt there also free for taking, I usually take 2 yard load of heavily composted grass clippings & wood chips to put in the gardens .
Always people dumping and people loading up like myself for their gardens , there should be such sites right in your area to take advantage of .
