Many American gardeners have a rusty barrel in the middle of their garden.
We can see this here too. However, in the US, metal barrels are not used for watering, but for collecting rust.
It is worth its weight in gold for local gardeners. We tell you how American gardeners use rust.
Why do American summer residents need rust?
American gardeners grind up the collected rust and dilute it with water, and use the resulting mixture for spraying.
They use it to cultivate the soil around garden beds, trees and bushes, in greenhouses and hothouses.
It turns out that rust is an effective remedy for pests such as aphids and spider mites.
Rust can also be used to prevent rot and mold.
