New lawn

My old lawn is very uneven and full of weeds. I have been given some Rosate weedkiller and told that if i spray the old lawn with it I can re lay turf on top of it after spraying. I have been told that there are different strenght ratios of weedkiller to water. Canm anyone help


  • No no no. You have an uneven lawn. This will make it worse. You can either apply a selective weedkiller in spring and then tipdress 2-3 times during the year to reduce the hollows, or spray the lawn with glyphosate, skim off the dead turf 2-4 weeks later, hire a rotovator and thoroughly dig over the whole lawn, adding sharp sand ideally, and lay the new lawn on this. Again, in spring.
