|Why do Bonsai houseplants have rocks cemented into place so you cannot access the soil?

|I know it's annoying but the rocks are glued in place to help anchor the plant and the soil while it's in transit, during handling, and while it's sitting on the store shelf. You can dissolve the glue by setting the pot in enough water to completely cover the tops of the rocks and allowing it to soak for about 30 minutes. You should be able to move the rocks around after the soaking and the glue should be gone.
