The answer to 'why is my stone walkway dying plants' is that the stone walkway is likely preventing adequate water and nutrient absorption for the plants. Stone walkways can create a barrier that restricts the flow of water, air, and nutrients to the soil and plant roots underneath.
Some common symptoms include wilting, discolored, or stunted plant growth along the walkway. Over time, this can lead to the plants completely dying off. The good news is that there are several solutions to address this issue and help your plants thrive again.
