Have a person that wants new beds put in, planted, and mulched where an existing lawn is along a fence. I know mulch can be bought by the bag or bulk. I need to know how much time on average it takes to put down mulch to price the job. The bed will be in the back yard, so the mulch will have to be wheel barreled through a 36" gate. So in this case I think bag will be faster to get into the back yard from the front. Thank you for your advice.
