Suppose you have had a grassy yard for more than 10 years and are tired of mowing, fertilizing and watering. Even worse, in recent years you have lost an ongoing battle with pearl scale, a soil disease that destroys patches of grass, and your yard is showing the damage. It's time to consider changing your landscape. With diseased soil, the best option is to shift from lawn to rock landscaping. But make sure you are firm in your decision to do so: once you begin the transition from grass to rock landscaping, it is difficult and time consuming to reverse the process.
Spray a heavy layer of grass killer over the entire yard to permanently kill the remaining grass. Remember that after this point there is no turning back to lawn unless you wish to wait a few months and reseed the yard.
Rake up the dead grass and bag it for disposal.
Cover the yard with a landscaping tarp. This thin, typically plastic or fabric material prevents weeds from growing and poking through the rocks.
Dig a 2-inch trench along the border of the area where the rocks are being placed. Tuck the tarp into this border.
Place bricks over the top of the trench, and cut any tarp that is peeking through the outside of the bricks.
Lay your rocks with a shovel, and rake them until their appearance is completely even.
