Killing a lawn and starting again
I've been fighting a losing battle with a poor, uneven, weed-riddled lawn. This year I plan to kill off the existing patch (about 30ft x 20ft) and relay with new turf.
Last year I added a brick edging to the lawn which means I'm in a position to raise the level of the lawn by a couple of inches. So, after killing the old lawn I was going to add appropriate top-soil to raise the level before laying turf.
What's the best process to achieve this?
1. What do I do to kill the lawn - whilst making sure that there's no harm to new turf?
2. How do I remove the dead thatch?
3. What time of year would be best to crack on with this project?
Thanks in advance for any advice.
