Hi,
We are orry to hear Westland Resolva didn’t work as expected despite following the instructions. If you’d like to discuss further, please contact us at customersupport@lawnsmith.co.uk.
“Easy to use, clear instructions. Seems to have done the job as no weeds have appeared during the 2 week wait between applying the weed killer and putting the lawn seed down. Good value compared to other weed killers available locally at the garden centre etc”
