Terra-cotta pots are great for container gardening and are an environmentally friendly alternative to plastic pots. But terra-cotta pots can break easily. Instead of tossing those shards in the trash, use them to improve your garden. Mix the shards in the soil under the eaves of your house, where rainwater can build up on stormy days. It will help with drainage, since terra cotta absorbs water. Plus, you won't see the shards since they are mixed in the soil.
