Have a large pot you’d like to plant cucumbers or flowers in? Don’t fill it up with planting soil! Save your soil and fill the base with Styrofoam first. The foam will reduce the overall weight of your planter, enabling you to move it around for best sun exposure. It also acts as good drainage for water.
We found some big chunks of styrofoam washed up on our local beach, so I knew that we wouldn’t be able to recycle it. If you don’t have a readily-available source on your beach, save a few styro-blocks to stuff into your large planters. If you’re concerned about the carcinogenic qualities of polystyrene, make sure you place the foam on the very bottom of the planter so the roots don’t touch it. Then, fill with good planting soil, ensuring you’ve filled in all the in-between spaces so your plants’ roots don’t dry out.
Studies aren’t conclusive whether there are any known effects of styrofoam or plastics in our soil upon our foods. If so, we’re in trouble. Almost all commercial compost has polystyrene and hard plastics throughout.
Most of our styrofoam gets recycled around Earth Day when a local feed store drives our styrofoam to a recycler on the other side of Puget Sound.
What do you think? Have you got your own reuse for Styrofoam? We’d love to hear from you.
