The answer to 'best time for landscape lighting' is that the optimal time to install landscape lighting is typically in the fall or early spring. This allows the lighting to be in place and fully functional before the winter months when the days are shorter and there is a greater need for exterior lighting.
Installing landscape lighting in the fall or early spring also gives the plants and landscaping time to adjust to any changes or modifications made during the installation process. This helps ensure the lighting blends seamlessly into the overall landscape design.
