Lynn, Proximity to the source and freight rates mean everything when it comes to rock. For a new bed I am putting in I am getting a truck load of probably 1/1/2" Sioux Quartzite. $46 per ton delivered but fuel is expensive these days.
For top dressing on a large semp bed would you use 3/4", 1", or 1 1/2"? 4" available too but that is more for rock mulch around very large plants in public spaces.
