The answer to 'why is my landscape lighting weeds' is that weeds can often grow around and under landscape lighting fixtures, especially if the soil around the fixtures is not properly maintained. This can be caused by a few common issues:
Inadequate soil preparation - If the soil around the lighting fixtures was not properly prepared and amended before installation, weeds can easily take root and thrive. Compacted or poor-quality soil provides the perfect environment for weed growth.
Lack of edging or mulch - Without proper edging or a thick layer of mulch around the fixtures, weeds can easily spread and encroach on the lighting area. The mulch and edging help suppress weed growth.
To solve this problem, you'll want to carefully remove any weeds, improve the soil, and add a 2-3 inch layer of mulch around the fixtures. If the issue persists, you may need to call a professional landscaper to properly maintain the lighting and surrounding area.
