Floor Dirt Toxic to Plant

Question

I work in a building where the janitorial staff keeps dumping the floor swept dirt into my plant – no matter how often I tell them not to. I work in an industrial area, so people have several kinds of chemicals on their shoes and it’s killing the plant. I’m wondering if there is any kind of lid or something that I could place on the top of the planter to prevent any dirt or grabage being put in on the plant and soil. Thanks!

Answer 1

I don't know of a lid that you can buy, but you can make one. Take a look at using an old tupperware lid of the correct width to cut and place over the soil.
