All you've got to do is a some simple wiring and a little digging in the garden.
Among the simplest creative reuse projects I've done, this landscape uplight is also one of my favorites. I mean, who knew that you could use an old chimney pot to cast a warm, 50-watt glow on the undersides of a Japanese maple's leaves? Well, besides me, there was the kind lady with the landscape lighting company, who hooked me up with a low-voltage spot that fits inside the chimney pot's base, as well as the 60-watt transformer, which plugs directly into an all-weather outlet. A key feature on the transformer is a built-in timer that will automatically turn the light on and off each night, so you'll never have to flip a switch.
