Removing Old Mulch, No Fabric

[Snapper12]

Only if it needs it, if it's crappy mulch and never breaks down it does need to be removed and replaced and with good organic mulch.

Best practice is to turn the mulch and top dress it. It should break down.

I took over an account a few years ago and the beds were about to spill over with mulch. We just turned it and put a thin layer on it. In about 2 season, back to adding a few inches mulch again....
