The answer to 'landscape lighting not growing' is that there could be several common causes, such as improper installation, electrical issues, or damage from pests or weather. The symptoms may include lights that won't turn on, dim or flickering lights, or lights that go out over time. The solutions can range from simple troubleshooting and repairs to more complex electrical work or even full replacement of the lighting system.
If the issue is related to improper installation, such as poor wiring connections or incorrect placement of the lights, this may be something a homeowner can fix themselves with some basic electrical skills. However, for more complex electrical problems or extensive damage, it's generally best to call in a professional landscaping or electrical contractor to diagnose and resolve the issue properly and safely.
