I have found a great way to enlarge a bed, Jan. I buy the oblong bales of straw, and they come apart in 'books', or so I'm told the name is, but like thick sheets, and I put them at the outside of the bed I want to enlarge. It kills the grass underneath, but I notice the ground will have a ton of earthworms in it. Then in the fall, or whenever it's ready to plant. I don't till. It looks kind of silly when the 'books' are laying there, but it does the job.
