How to Choose the Best Weed Killer
The best weed killer depends entirely on where you're treating. Use a selective weed killer on a lawn to kill broad-leaved weeds without harming the grass. Use a total (glyphosate) weed killer on paths, patios and driveways where you want to clear everything. Using the wrong type is the most common — and most expensive — mistake.
This guide compares the four main weed killer categories stocked by Ransley Pro Grow — professional-grade, UK-approved formulations trusted by groundscare contractors, landscapers and local authorities since 1951.

Best Weed Killer by Surface & Need
Best for lawns (selective)
To kill dandelions, daisies, clover and plantains without harming the grass, use a selective lawn weed killer like Depitox or Dicophar. These liquid concentrates are diluted and applied by sprayer when weeds are actively growing (May–July). For a one-step option, Nutrigrow Feed, Weed & Moss Killer fertilises the grass while controlling weeds and moss in a single application.
Best for paths, patios & driveways
On hard surfaces you want to clear completely, a total weed killer is the right choice. Glyphosate-based concentrates are systemic — they travel from the leaf to the root, killing the whole plant. For paving and gravel, a path & patio weed killer with residual action gives fast knockdown plus a barrier that prevents regrowth for weeks.
Best for moss alongside weeds
If your lawn has moss as well as weeds, a Feed, Weed & Moss 3-in-1 granular product is the most efficient solution. It feeds the grass, kills broad-leaved weeds and blackens moss in one pass — saving you two separate treatments. Apply from April to September when the lawn is moist and growth is active.
Best for home & garden borders
For general weed control around the garden — beds, borders and uncultivated ground — a home & garden weed killer offers broad-spectrum control in a ready-to-use or concentrate form. Apply carefully on a still day to avoid drift onto wanted plants, and spot-treat where possible to minimise chemical use.
