Creating a new mulch bed
I've wanted to create a new, sizeable mulch bed in my back yard which consists of mostly clover and some grass. I overbought mulch for another area so I want to use it. I have access to a power tiller but not a sod cutter. Can I define the shape of the mulch bed and then till the soil to cut up the clover and existing grass?
I'm talking an area about 30 feet wide by 10 feet deep or so. Removing the existing stuff is not the hassle, getting rid of it is and I don't have too much space to let it stack up.
Will I just be fighting off clover and grass as it grows back up through the mulch or if I till it all over, will the mulch help smother it out?
