ROCKY SITUATION

 When I first established this bed, I placed the rock border in a nice thick bed of sand. Little did I know that our expanding clay soil was like quicksand...only in slow motion. So 5 years later the large base rocks were totally submerged in the dirt with only the top layer showing.  

This year I planned to enlarge this bed a bit and found that I had to dig out all the rock border. This time I have used a substantial base of gravel to keep the rocks from sinking (I hope). Time will tell on that! Check with me in 5 years! I got this done just in time as we've had over .5" of rain overnight.
