These planters are awesome! We have received so many complements. We used the recipe on some of the planters to make them oxidize quicker (photographed above). The planters that didn't get the recipe for oxidation have oxidized a little darker. But all are gorgeous and look great together! Yes, when it rains the rust stains the concrete but get some Rust Out or Iron Out and spray it on concrete and rinse off and BAM it's gone. No scrubbing needed. These planters are heavy. We live in TX so I left the styrofoam inside (like a reviewer suggested) to help keep plants cooler. We started with one planter and now we have 4. Great Purchase!
