Help with soil preparation for new lawn
I'm needing some help with preparing my soil for a new lawn as I have no idea what I'm doing. So far I've started to kill off the old lawn with glyphosate and it's turned to what I can describe looks like straw. My garden is uneven and full of stones etc so I would like to get it nice and level before either seeding or turfing but I don't know what to do next.
Should I just rotavate the soil and level it out or do I need some top soil? Any advice would be helpful.
