What are some cheap containers that can be used for gardening?

teapots of all sizes, kettles.. old kitchen pots that have "seen their day" .. gavanized buckets (they come in SO many sizes and shapes), old paint cans .. a kid's old wagon looks awesome all planted :) I cant wait to see all the other suggestions!

here are some cute ideas I found, scavenge some yard sales

Old chairs,Metal buckets with drainage holes,old work boots ,rubber clogs,rain boots,pocket books. The ideas are endless.

Old wheelbarrows look great with a flourish of colorful flowers in them.

old boots, galvanized pans brightly painted, dollar store tubs.

If you want something really big use old bath tub or stock tank
