The answer to 'why is my landscape lighting erosion' is that erosion around landscape lighting is a common problem caused by factors like water runoff, soil type, and improper installation. Symptoms can include exposed wiring, unstable fixtures, and pooling water around the lights. To fix this, you may need to adjust drainage, add soil amendments, or re-level the lighting fixtures.
In many cases, minor erosion can be addressed with DIY solutions like adding gravel, redirecting water flow, or resetting the lights. However, for more significant erosion issues or complex drainage problems, it's best to call a professional landscaper or electrician to properly diagnose and resolve the problem.
