One nice and CHEAP way to light up your garden is to use Solar Powered Lights. These Solar Lights can be easy to install (put it together and stick it in the ground), and cost nothing once bought (unless you need to replace the batteries or bulbs, which shouldn’t happen very often).
I bought a couple of solar lights for my garden, and they work like a charm. They’re cute little things that just illuminate a section of the garden. I’m sure you can get solar lights with more powerful light bulbs, but the ones I bought are just there to accentuate and add a little bit of style to the garden.
You can even get solar fountains to add to your garden, which I think is a pretty clever idea, but if you already have a fountain or water feature, you could add a solar light or 2 around your feature, and voila, it is visible and highlighted all night. Now that’s just GREAT for those evening parties or dinners.
