Concerns about the widespread use of glyphosate in public parks and open spaces, including gardens, has led to the marketing of several unconventional alternative methods for weed control that do not rely on chemicals alone. Examples include foams, applied with hot water containing plant oils and sugars; pulses of electricity, which can kill plants by destroying the vascular bundles; microwaves, that can kill weed seeds in the soil; and directed burning with a naked flame. While these treatments may be chemical‐free, they can be labour intensive, costly, often require more than one treatment and have their own risks associated with use.
