Improve Your Environment
Conventional weed killers can leave lingering chemical residues. FireHawk Bioherbicide’s naturally powerful formula hits weeds hard above ground then returns to nature below ground. Reassurance that chemical residues aren't lingering in your garden.
Soil Health and Repair
Weeds thrive in disturbed and tilled soils meaning they'll keep come back again and again. FireHawk Bioherbicide helps improve soil health by minimising tillage and feeding soil microorganisms. This allows healthy vegetation to thrive, minimizing the growth of new weeds.
