The answer to 'landscape lighting overgrown' is that overgrown vegetation can block and obscure landscape lighting, reducing its effectiveness. Common causes include plants and trees growing larger over time, improper initial placement of the lights, or lack of regular maintenance and trimming. Symptoms include dimly lit areas, shadows, and lights that are no longer visible or illuminating the intended areas.
The solution is to regularly trim and prune any plants, trees, or bushes that are encroaching on the landscape lighting. This may require a one-time more extensive trimming or pruning, followed by periodic maintenance every 6-12 months to keep the lights clear. For DIY homeowners, this can often be done with basic gardening tools. However, for larger or more complex landscaping, it's best to hire a professional landscaper or arborist to ensure the job is done safely and effectively.
