Trash Hacker: Styrofoam Planter Filler

By Liesl Clark

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.

So save a few styro-blocks to stuff into 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.

    Thanks for the idea. I shared it with somebody who found a large chunk on the beach (and which he would have recycled had it been in pristine condition).

      That’s great, Diane. It’s a decent reuse for that “sea foam” as we call it.

    [...] some large chunks of styrofoam on your beach, it can’t be recycled but you might be able to reuse it in a large planter as drainage and to lower the overall weight of your planted [...]
