Colder weather gardeners will appreciate this mini-greenhouse made out of old windows and straw bales. The glass lets in light while the straw holds in the heat, creating a great outdoor space to sprout seedlings early in the year.

This one requires some sawing, but that just makes it more fun. If you don't have an old dresser lying around in your garage, you can probably pick one up at a local thrift store. Cut open the top and stagger the drawers to create terraced garden beds.

Fill some old rain gutters with potting soil and hang them along a bare outdoor wall to grow a garden without any floor space. Gutters can be bought new for just a few dollars a foot, but try scrap yards if you want to give waste metal a new home.

This picture shows up all over the internet, so we don't know who deserves credit for it. (We found it at Junk Drawer Décor.) Every tire store has piles of used tires awaiting recycling. Paint them, stack them, and fill them with potting soil for a funky urban garden in a small space.

Everything about these is simple: simple to find, simple to add drainage, simple to hang. Collect as many cans as you have space for, and use them to grow herbs or flowers.

The color pattern of these red and green two-liter bottles make this planter arrangement especially sexy. The great thing about the idea, though, is that you can use as many or as few bottles as you need to take advantage of the wall space you have. We love this idea for growing herbs and flowers, but also for light vine-grown veggies like snap-peas.
Our social media platforms have been flooded with images of people building gardens out of all kinds of waste materials.
With a little ingenuity, everything from egg shells to yogurt containers to old closet doors can be diverted from landfills and recycling centers to become vehicles for growing food or flowers.
