My vegetable garden needs some love now that the drought has broken and we are getting some decent rain!! :)
The internet tells me that 50 square feet < 5 square metres. The area that I mulched is 2m x 3m, so that should be sufficient for the bb (I intend to do the entire vegetable garden over the next couple of days).
The mulch was chopped and dropped directly into the bed, then I started on weeds and things growing on the pathways and then I started on the weeds in the surrounding area, no more than a 15 metre circumference from the garden. I used a pair of scissors to do the chopping (they broke and I got blisters, I think I need one of those curved knives).
