So instead of using the black ground cover that is sold in garden supply stores (for a high price), I bought inexpensive light weight tarps from the Dollar Store. I also used some left over scrap linoleum from a friend. I covered the areas that I wanted to mulch. The tarps worked wonderfully because they already have the holes in them for me to put the peg into (to hold it down to the ground). I decided to let the walkway remain grassy and am going to put step stones on it. They won't actually be "stones" though...they will be things that I already have or things that I find. Currently I am using old door mats for the "stones"...but I don't have enough so I am going to have to get creative. On both sides of the walkway will be mulch.
In different places in the mulched area will be a garlic bed, a strawberry bed, blueberry bushes, a tree and grape vines. The kid's pool is also up here (because it is the only area in the yard that is actually flat and not on a slope).
This area shows the mulched area and the dirt bed where I am going to plant wildflowers (the triangle area). The area with rocks is a little water garden.
