I loved this idea..What a clever mind!!!

When Suzanne Forsling moved to Juneau Alaska from Iowa, she found that it was a little bit harder to get her garden to grow. Frustrated by cold soil, scarce sunlight, hungry slugs, root maggots, porcupines, cats, bears and ravens she got resourceful. She got her crops off the cold ground and into the light by afixing gutters to the wood siding of her house on the sunny side and using them as planters.
This is really a great space saving idea for those with green thumbs and not enough yard to exercise them. Personally I think these would go great along a deck railing or cut down to be mini-window boxes. So next time someone you know replaces their gutters snatch them up and give them a new lives as planters.
