Maximum mulch performance
‘‘Chop and drop’’ weeds and leave them on top of the garden bed. Don’t do this with grasses and couch grass that will easily re-root.
Chop some comfrey and place it around your tomatoes at regular intervals during the growing season.
Spread grass clippings thinly over your beds if you don’t want to compost them. Top up the mulch every time you mow.
You can also use plants as living mulches for your other plants, by using plants to suppress weeds and keep the soil cool. More on that another time.
