(We've done this for 2 years now and I will never garden without mulch again!) Ruth Stout, no- work garden, this is one great concept for anyone wanting to garden effectively and easily! from Mother Earth News
DIY Simple Backyard Shade - PVC pipe in a bucket, then pour cement around it. Once dry, put bucket into tall planter, surround bucket w/ gravel, then top w/ soil. (Not covering pipe) Stick bamboo pole into the pipe & hang fabric w/ ties through grommets.
Brick pavers make a simple, handsome border and work well as edging material. They're ideal for a wide border that keeps grass out of the garden, yet allows flowers etc. to spill over without intruding onto the grass.
