One of the first locations I put the rocks in was the front sidewalk garden. That bed was completely without a border before and now has an edge all along the side with the grass. I replaced a few of the original rocks I used in the front garden with different ones that I think have more character. The one on the left is my favorite. It has a nice round shape that will look very cool once the phlox grows in all around it. The one in the upper right has a round flat top that hangs over the rock next to it and the one in the bottom right I like because of it's thickness and consistency. It almost looks like a retaining wall block.
The self-seeding garden also got the stone border treatment, at least on the backside where it joins up with the border garden. I really like having rocks that are large enough to sit on spaced every now and then in the border. It adds a convenient seat for anyone walking by who might want to stop and enjoy a particular angle of the garden. It also makes for a great spot to sit and weed the garden.
With these rocks I edged the entire length of the border garden except for about 5-7 feet. I'll have to go on another rock hunt soon to finish it all up.
I still have a couple other uses for all that rock to show you. Stay tuned for more rock gardening!
