Residual weedkillers remain active in the top layer of the soil for an extended period, providing long term control of weeds.

  They work by preventing any weed seeds from germinating or by inhibiting the growth of young seedlings present. Their persistence can vary depending on the specific chemical, soil type, climate, and application method.

Long lasting weed control works well on surfaces such as gravel driveways and pathways, keeping them weed free for up to 6 months. If you have existing weeds, you could consider adding a total weedkiller such as Round Up Pro Vantage 480

While effective for weed management, residual herbicides require careful consideration to avoid harming desirable plants
