So glad I found this forum. I will apologise straight away as I am a complete novice at gardening in general and could use some advice.

We've moved into a new house and the lawn is in a bad state so we have decide that it is the best to kill it off and re turf. Once I kill the lawn and weeds, I was told by a friend that I would need to hire a rotavator to churn up the earth, rake it and pull out clumps and weeds etc, and then put a top soil down. Is this about right? I just want to be sure I am being pointed in the right direction!!

I've read on websites about soil improvers. Is that something I would use in addition to the top soil? Also, and idea how long to wait bewteen putting weed/lawn killer down and proceeding with turf laying? I read somewhere that it should be about 6 weeks?

Many thanks for any responses
