Before you decide to dispose of your landscape rock, you should look into options where the rock could be repurposed. Post on social media like Facebook marketplace or Nextdoor to see if anybody nearby would be willing to take them for free. Alternatively, try to think about ways you could reuse the rock on your own property. For example, rock can be reused as fill for a retaining wall or base for a paver patio. Or you could make a berm by piling up the rock and then adding a fresh 2-3 inch layer of dirt on top.
