Green bottles on the edge
Empty glass bottles can be put to a good second use as edging for garden pathways. A trench slightly wider than a bottle is dug along the perimeter of the beds to be enclosed. Clean bottles are sunk neck-first into the earth, to approximately two-thirds of their height. Backfilling the spaces around the bottles ensures they are firmly held in place. Glass bottles are not used to edge vegetable beds. Bottle edging is never stepped upon, and care is taken when using tools nearby.
