Does Boiling Water Really Kill Weeds?

How Long Does It Take Boiling Water to Kill Weeds?

The amount of time it takes for boiling water to kill weeds depends on the type of weed and its size. Smaller annual weeds will die almost immediately after contact with boiling water, while larger perennials may take several minutes or longer before they succumb to the heat.
