The answer to 'landscape lighting erosion' is that landscape lighting can sometimes cause soil erosion around the fixtures. This is usually due to poor drainage, improper installation, or excessive water runoff from the lighting. Symptoms include visible soil loss, pooling water, and damage to the landscaping around the lights.
To fix landscape lighting erosion, start by ensuring proper drainage around the fixtures. This may involve adding gravel, French drains, or other drainage solutions to divert water away from the area. You should also check the installation to make sure the lights are level and the soil is properly compacted around them. In some cases, you may need to relocate the lights to a better-draining area. For more serious erosion, it's best to call in a professional landscaper who can assess the issue and provide a long-term solution.
