Flame weeding is a non-chemical weed control method that uses brief, intense heat to damage plant cells, causing dehydration and death. It’s most effective on young, broad-leaved weeds and is commonly used before crop emergence or early in crop growth. Suitable for both small and large-scale horticulture, it requires careful timing, crop selection, and operator training. While effective, it can be costly due to propane use and equipment needs, and may harm beneficial insects. Weather conditions, burner height, and tractor speed all influence success. With proper management, flame weeding offers a sustainable alternative to herbicides in weed control.
