Removing Weeds from Your Lawn: Herbicides, Overseeding and Prevention

Our goal was to map the complete weed management process – not just the first step. We therefore specifically looked for products that fit into three phases: a selective herbicide for the actual weed elimination, fast-germinating overseeds for closing the gaps, and a lawn fertiliser that acts preventively over the long term. The selection was informed by manufacturers' stated use cases, ratings from several thousand buyers each, and concrete product characteristics – spectrum of action, area coverage and nutrient composition.

Not every weed problem calls for the same intervention. Individual dandelion plants can be removed with a weeding tool without needing a herbicide. But anyone dealing with widespread clover, broadleaf plantain or ground elder – species that spread vegetatively or grow flat and escape the mower – quickly hits the limits of purely mechanical methods. This is exactly where selective herbicides begin to prove their worth. The second scenario concerns overseeding: once the herbicide has worked, gaps appear that become the next entry point for weeds without prompt action. The third scenario is prevention: a well-fertilised, dense lawn simply leaves weeds no room.

COMPO Rasenunkraut-Vernichter Banvel Quattro is the only product in this selection that acts directly against weeds. It is formulated as a concentrate that, according to the product description, specifically targets hard-to-control broadleaf species such as clover, plantain and ground elder. For the phase that follows, two overseeds are available: WOLF-Garten LR25 for smaller areas up to 25 m², and COMPO Turbo Nachsaat for up to 50 m². Anyone who also wants to protect the lawn long-term against new weeds reaches for the Turbogrün summer fertiliser – it strengthens the lawn throughout the entire summer season, when weeds grow most aggressively.

Weed control in a lawn is not a one-time event but a process. Phase 1: the herbicide is applied in dry weather; broadleaf weeds die off while the grass is spared. Phase 2: after the action period, the dead plant material is removed – and the bare patches are immediately overseeded. Phase 3: the lawn receives fertiliser to carry it through the critical summer season. Anyone who consistently follows all three phases will find that renewed weed pressure noticeably diminishes – because the lawn simply offers no more gaps.
