The answer to 'landscape lighting overgrown' is that overgrown vegetation can often obscure and interfere with landscape lighting. Common causes include bushes, trees, and other plants growing too large and blocking the light. Symptoms include dark or uneven lighting, reduced visibility, and an unkempt appearance. The solution is to regularly trim and maintain the landscaping around your outdoor lights.
For DIY homeowners, this typically involves pruning back any overhanging branches, bushes, or other vegetation that is obstructing the light fixtures. Use pruning shears, loppers, or a hedge trimmer to carefully cut back the growth without damaging the lighting. Be sure to dispose of any trimmings properly. If the problem is more extensive or you're not comfortable working with electrical components, it's best to call a professional landscaper or lighting technician to assess and resolve the issue.
